+[![Actions Status](https://github.com/Dador/JavascriptSubtitlesOctopus/workflows/Emscripten/badge.svg)](https://github.com/Dador/JavascriptSubtitlesOctopus/actions)
+
+SubtitlesOctopus displays subtitles in .ass format and easily integrates with HTML5 videos. It supports all SSA/ASS features and fully compatible with [libass](https://github.com/libass/libass).
+
+[ONLINE DEMO](https://dador.github.io/JavascriptSubtitlesOctopus/videojs.html) / [other examples with demo](https://dador.github.io/JavascriptSubtitlesOctopus/)
+
+## Features
+
+- Supports all SSA/ASS features
+- Supports any fonts (including woff2 fonts)
+- Works fast (because uses WebAssembly with fallback to asm.js if it's not available)
+- Uses Web Workers thus video and interface doesn't lag even on "heavy" subtitles (working in background)
+- Doesn't use DOM manipulations and render subtitles on single canvas
+- Fully compatible with [libass](https://github.com/libass/libass)
+- Easy to use - just connect it to video element
+
+## Included Libraries
+
+* expat
+* fontconfig
+* freetype
+* fribidi
+* harfbuzz
+
+## Usage
+
+To start using SubtitlesOctopus you only need to instantiate a new instance of
+`SubtitlesOctopus` and specify its [Options](#options).
+
+```javascript
+var options = {
+    video: document.getElementById('video'), // HTML5 video element
+    subUrl: '/test/test.ass', // Link to subtitles
+    fonts: ['/test/font-1.ttf', '/test/font-2.ttf'], // Links to fonts (not required, default font already included in build)
+    workerUrl: '/libassjs-worker.js', // Link to WebAssembly-based file "libassjs-worker.js"
+    legacyWorkerUrl: '/libassjs-worker-legacy.js' // Link to non-WebAssembly worker
+};
+var instance = new SubtitlesOctopus(options);
+```
+
+After that SubtitlesOctopus automatically "connects" to your video and it starts
+to display subtitles. You can use it with any HTML5 player.
+
+[See other examples](https://github.com/Dador/JavascriptSubtitlesOctopus/tree/master/example).
+
+### Using only with canvas
+You're also able to use it without any video. However, that requires you to set
+the time the subtitles should render at yourself:
+
+```javascript
+var options = {
+    canvas: document.getElementById('canvas'), // canvas element
+    subUrl: '/test/test.ass', // Link to subtitles
+    fonts: ['/test/font-1.ttf', '/test/font-2.ttf'], // Links to fonts (not required, default font already included in build)
+    workerUrl: '/libassjs-worker.js' // Link to file "libassjs-worker.js"
+};
+var instance = new SubtitlesOctopus(options);
+// And then...
+instance.setCurrentTime(15); // Render subtitles at 00:15 on your canvas
+```
+
+### Changing subtitles
+You're not limited to only display the subtitle file you referenced in your
+options. You're able to dynamically change subtitles on the fly. There's three
+methods that you can use for this specifically:
+
+- `setTrackByUrl(url)`: works the same as the `subUrl` option. It will set the
+  subtitle to display by its URL.
+- `setTrack(content)`: works the same as the `subContent` option. It will set
+  the subtitle to dispaly by its content.
+- `freeTrack()`: this simply removes the subtitles. You can use the two methods
+  above to set a new subtitle file to be displayed.
+
+```JavaScript
+var instance = new SubtitlesOctopus(options);
+
+// ... we want to change the subtitles to the Railgun OP
+instance.setTrackByUrl('/test/railgun_op.ass');
+```
+
+### Cleaning up the object
+After you're finished with rendering the subtitles. You need to call the
+`instance.dispose()` method to correctly dispose of the object.
+
+```JavaScript
+var instance = new SubtitlesOctopus(options);
+
+// After you've finished using it...
+
+instance.dispose();
+```
+
+
+### Options
+When creating an instance of SubtitleOctopus, you can set the following options:
+
+- `video`: The video element to attach listeners to. (Optional)
+- `canvas`: The canvas to render the subtitles to. If none is given it will
+  create a new canvas and insert it as a sibling of the video element (only if
+  the video element exists). (Optional)
+- `subUrl`: The URL of the subtitle file to play. (Require either `subUrl` or
+  `subContent` to be specified)
+- `subContent`: The content of the subtitle file to play. (Require either
+  `subContent` or `subUrl` to be specified)
+- `workerUrl`: The URL of the worker. (Default: `libassjs-worker.js`)
+- `fonts`: An array of links to the fonts used in the subtitle. (Optional)
+- `availableFonts`: Object with all available fonts - Key is font name in lower
+  case, value is link: `{"arial": "/font1.ttf"}` (Optional)
+- `timeOffset`: The amount of time the subtitles should be offset from the
+  video. (Default: `0`)
+- `onReady`: Function that's called when SubtitlesOctopus is ready. (Optional)
+- `onError`: Function called in case of critical error meaning the subtitles
+  wouldn't be shown and you should use an alternative method (for instance it
+  occurs if browser doesn't support web workers). (Optional)
+- `debug`: Whether performance info is printed in the console. (Default:
+  `false`)
+
+### Fast Render Mode (Lossy) (EXPERIMENTAL)
+The Fast Render mode has been created by @no1d as a suggestion for fix browser freezing when rendering heavy subtitles (#46), it use [createImageBitmap](https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/createImageBitmap) to render the bitmap in the Worker, using Promises instead of direct render on canvas in the Main Thread. When the browser start to hang, it will not lock main thread, instead will run Async, so if the function createImageBitmap fail, it will not stop the rendering process at all and may cause some bitmap loss or simply will not draw anything in canvas, mostly on low end devices.
+
+**WARNING: Experimental, not stable and not working in Safari**
+
+To enable this mode set the option `lossyRender` to `true` when creating an instance of SubtitleOctopus.
+
+### Brotli Compressed Subtitles
+The SubtitleOctopus allow the use of compressed subtitles in brotli format, saving bandwidth and reducing library startup time
+
+To use, just run: `brotli subFile.ass` and use the .br result file with the subUrl option
+

-### v0.11.0 - 2016/01/24
-- BREAKING CHANGE - WebRenderer.resize(width, height) used to have a broken implementation of letterboxing to move the subs div right or down. Now it's WebRenderer.resize(width, height, left, top) and expects the caller to calculate letterboxing itself and supply left and top accordingly. DefaultRenderer does it using the video resolution and users of WebRenderer can do the same.
-- BREAKING CHANGE - DefaultRenderer.resize() now ignores its parameters and always resizes to its video element's dimensions. It had already stopped resizing the video element when it was renamed from resizeVideo in v0.6.0, so it doesn't make sense to let it take a completely different width and height.
-- BREAKING CHANGE - Removed fullscreen support in DefaultRenderer. It started out as a hack using max z-index and works on even fewer browsers now. It probably didn't work for you anyway so it should be no big loss.
-- Implemented experimental support for \t
-- Added RendererSettings.fallbackFonts to set the fallback fonts for all styles. Defaults to 'Arial, Helvetica, sans-serif, "Segoe UI Symbol"'.
-- Better compatibility with loose ASS scripts - assume unnamed first section is Script Info, fall back to Default style for missing styles, recognize arbitrary-case property names, normalize asterisks in style names, etc.
-- Various font size improvements - faster calculation, fix for incorrect size when line-height is overridden by site CSS, fix for incorrect scaled sizes for letterboxed subs, fix for incorrect metrics for web fonts, etc. The last one requires that all web fonts be specified in RendererSettings.fontMap to be rendered accurately.
-- WebRenderer now supports using local() URLs in addition to url() in CSS font-face rules.
-- Added RendererSettings.useAttachedFonts. If true, TTF fonts attached to the script will be used in addition to fonts specified in RendererSettings.fontMap. This setting is false by default, and should only be enabled on trusted fonts since it uses a very naive base64 and TTF parser to extract the font names from the attachment. It also requires ES6 typed arrays - ArrayBuffer, DataView, Uint8Array, etc. in the environment.
-- Various pre-render, SVG filter and DOM perf improvements.
-- Fixed \fscx and \fscy to not scale shadows.
-- Fixed \fscx and \fscy to have optional values.
-- Fixed \fs+ and \fs- to have required values.
-- Fixed \r<target_style> to use the target style's alpha values instead of 1.
-- Fixed \fad subs to not flash after the fade-out ends with low-resolution clocks.
-- Fixed outlines to not be darker than they should be.
-- Fixed styles to not ignore the ScaleX and ScaleY properties in the script.
-- Fixed lack of sufficient space between normal and italic text.
-- Fixed SVG filters to interpolate in sRGB space instead of RGB.
-- Fixed ASS parser to complain if a script doesn't have a Script Info section at all.
-- The promise returned from ASS.from*() is now properly rejected due to errors from loading the script, instead of just remaining unresolved forever.
-- Fixed SRT parser to swallow UTF-8 BOM just like the ASS parser.
-- Fixed all clocks to suppress redundant ticks if the current timestamp hasn't change from the last tick.
-- Fixed {AutoClock, VideoClock}.{setEnabled, toggle} methods to actually enable / disable the high-resolution timer.
-
-
-### v0.10.0 - 2015/05/05
-- Implemented libjass.renderers.AutoClock, a clock that automatically ticks and generates clock events according to the state of an external driver.
-- Implemented \k
-- libjass.{Set, Map, Promise} can now be set to null to force the use of the polyfills, even if it defaulted to a runtime-provided implementation.
-- Added ASS.fromReadableStream(), a function that can be used to parse ASS from a readable stream such as the response of window.fetch().
-- ASS.fromUrl() now tries to use window.fetch() if available instead of XMLHttpRequest.
-- Fixed constant pausing and playing on Firefox triggered by how slowly it updates video.currentTime (wasn't noticeable but still undesirable).
-- Fixed a dialogue's animation state not getting updated while seeking if the start and end times of the seek were within its start and end times.
-- Fixed wrapping mode 1 (end-of-line wrapping) to actually wrap.
-- Fixed parser to parse the time components of karaoke tags as centiseconds instead of seconds.
-- Fixed parser to swallow leading BOM, if any.
-- Fixed errors reported by webworker API were empty objects without message and stack properties.
-
-
-### v0.9.0 - 2014/11/27
-- BREAKING CHANGE - ASS.fromString() now returns a Promise of an ASS object, not an ASS object directly. The synchronous ASS parser used by ASS.fromString() is no more.
-- BACKWARD-COMPATIBLE CHANGE - WebRenderer constructor parameters order has changed from (ass, clock, settings, libjassSubsWrapper) to (ass, clock, libjassSubsWrapper, settings). The constructor will detect the old order and reorder accordingly.
-- Added ASS.fromStream and ASS.fromXhr that read a stream and an XMLHttpRequest object's response respectively and return (a Promise of) an ASS object. Both of these parse the script asynchronously.
-- Added RendererSettings.enableSvg that can be used to toggle the use of SVG filter effects for outlines and blur.
-- libjass.js now has an AMD wrapper so that it can be used with RequireJS, etc.
-- Settings parameter is now optional for WebRenderer and DefaultRenderer.
-- Added support for clock rates apart from 1 to clocks and renderers.
-- Added a parameter to libjass.createWorker to specify the path to libjass.js that will run in the worker.
-- Fixed Style and Dialogue constructors not setting defaults for missing properties.
-- Fixed color and alpha parser to support more formats.
-- Fixed SRT parser to replace all HTML tags it finds, instead of just the first one.
-- Fixed font size calculation to use the vertical scale instead of horizontal.
-- Fixed line-height on newlines.
-- Fixed missing perspective on X and Y rotations.
-
-
-### v0.8.0 - 2014/08/16
-- Added web worker support. libjass.parse can now be offloaded to a web worker.
-- Implemented \fs+ and \fs-
-- Added ASS.addEvent() to add dialogue lines to an ASS object.
-- Renamed ClockEvent.TimeUpdate to ClockEvent.Tick, and added ClockEvent.Stop
-- Clock.enable() and .disable() now return a boolean to indicate whether the function had any effect.
-- Added Clock.setEnabled() to force the enabled-state to the given value.
-- Renamed ManualClock.timeUpdate() to ManualClock.tick()
-- Moved WebRenderer.enable(), .disable() and .enabled to NullRenderer
-- Fixed not being able to parse tags with default values.
-- Fixed font preloader downloading the same font multiple times because it didn't filter for duplicates.
-- Fixed min-width value not taking separate left and right margins into account.
-- Fixed absolutely positioned subs were always left-aligned even if they had an alignment tag.
-- Fixed blur and outlines getting truncated.
-
-
-### v0.7.0 - 2014/05/15
-- Implemented \be
-- Split a new renderer, WebRenderer, off DefaultRenderer that doesn't rely on a video element.
-- All renderers now require a Clock to generate time events. VideoClock is a Clock backed by a video element, while ManualClock is a clock that can be used to generate arbitrary time events.
-
-
-### v0.6.0 - 2014/03/24
-- All script properties and style properties are now parsed and stored in the ASS and Style objects.
-- Basic SRT support, by passing in a libjass.Format argument to ASS.fromString()
-- \clip and \iclip now have their drawing instructions parsed as an array of libjass.parts.drawing.Instruction's instead of just a string.
-- Added DefaultRenderer.enable(), DefaultRenderer.disable() and DefaultRenderer.toggle() to change whether the renderer is displaying subtitles or not.
-- DefaultRenderer.resizeVideo is now called DefaultRenderer.resize. Now it only resizes the subtitle wrapper div, not the video element.
-- Replaced the 41ms setInterval-bsed timer with a requestAnimationFrame-based timer to reduce load on minimized or hidden browser tabs.
-- DefaultRenderer now renders dialogues in the correct order according to the script.
-- Fixed incorrect font sizes.
-- Replaced jake with gulp.
-
-
-### v0.5.0 - 2014/01/26
-- Removed preLoadFonts renderer setting. It was redundant with the actual fontMap setting since the presence or absence of that setting is enough to signal whether the user wants to preload fonts or not.
-- Multiple renderers can now be used on the same page without conflicting with each other.
-- Implemented \shad, \xshad, \yshad
-- Fixed ASS draw scale being used incorrectly.
-- ASS.resolutionX and ASS.resolutionY are now properties of ASS.properties, a ScriptProperties object.
-
-
-### v0.4.0 - 2013/12/27
-- All parts moved from the libjass.tags namespace to the libjass.parts namespace.
-- Replaced PEG.js parser with a hand-written one. This allows for parsing lines that are strictly invalid grammar but are parsed successfully by VSFilter or libass.
-- All ASS tags are now supported by the parser.
-- Removed the useHighResolutionTimer setting for DefaultRenderer. DefaultRenderer always uses the 41ms timer now.
-- Implemented \move
-- Implemented ASS draw
-- Fixed subs overflowing the video dimensions still being visible.
-- SVG filters are now used for outlines and blur.
-- Delay parsing of dialogue lines till they need to be pre-rendered. As a side-effect, all fonts in the font map are preloaded now, not just the ones used in the current script.
-
-
-### v0.3.0 - 2013/10/28
-- Moved libjass.DefaultRenderer to libjass.renderers.DefaultRenderer
-- Added libjass.renderers.NullRenderer, a renderer that doesn't render anything.
-- DefaultRenderer's fontMap setting is now a Map instead of an Object. It now supports more than one URL for each font name.
-- DefaultRenderer now generates the subtitle wrapper div itself.
-- DefaultRenderer now takes video letterboxing into account when resizing the subtitles.
-- DefaultRenderer has a new setting useHighResolutionTimer that makes it use a 41ms timer instead of video.timeUpdate's 250ms timer.
-- div IDs and CSS class names are now prefixed with "libjass-" to avoid collisions with other elements on the page.
-- All numeric CSS property values are now truncated to three decimal places.
-- Added ```jake watch``` that rebuilds and runs tests on changes to the source.
-- Added ```jake doc``` that builds API documentation.
-- Added Travis CI build.
-
-
-### v0.2.0 - 2013/09/11
-- Added libjass.DefaultRenderer, a class that handles initializing the layer div's, preloading fonts, and drawing Dialogues based on the current video time.
-- libjass.js can now be loaded in node. Only the parser can be used.
-- Tests can now be run with ```jake test``` or ```npm test``` using Mocha.
-
-### v0.1.0 - 2013/08/29
-- First npm release.

-[![Build Status](https://travis-ci.org/Arnavion/libjass.png?branch=master)](https://travis-ci.org/Arnavion/libjass)
-
-libjass is a JavaScript library written in TypeScript to render ASS subs in the browser. [Check out the demo.](http://arnavion.github.io/libjass/demo/index.xhtml)
-
-
-### What's special about libjass?
-
-* libjass requires no tweaks to the ASS file from the original video.
-
-* libjass uses the browser's native CSS engine by converting the components of each line in the ASS script into a series of styled &lt;div&gt; and &lt;span&gt; elements. This allows all the layout and rendering to be handled by the browser instead of requiring complex and costly drawing and animation code. For example, libjass uses CSS3 animations to simulate tags such as \fad. While a canvas-drawing library would have to re-draw such a subtitle on the canvas for every frame of the video, libjass only renders it once and lets the browser render the fade effect.
-
-As a result, libjass is able to render subtitles with very low CPU usage. The downside to libjass's aproach is that it is hard (and potentially impossible) to map all effects possible in ASS (using \t, ASS draw) etc. into DOM elements. As of now, the subset of tags supported by libjass has no such problems.
-
-
-### I want to use libjass for my website. What do I need to do?
-
-You can install the latest release of libjass
-
-* using npm with `npm install libjass` and load with `var libjass = require("libjass");`
-* using bower with `bower install https://github.com/Arnavion/libjass/releases/download/<release name>/libjass.zip`
-* using jspm with `jspm install github:Arnavion/libjass` and load with `import libjass from "Arnavion/libjass";`
-
-Inside the package, you will find libjass.js and libjass.css, which you need to load on your website with your video.
-
-Alternatively, you can build libjass from source by cloning this repository and running `npm install`. This will install the dependencies and run the build. libjass.js and libjass.css will be found in the lib/ directory.
-
-Only libjass.js and libjass.css are needed to use libjass on your website. The other files are only used during the build process and you don't need to deploy them to your website.
-
-
-### What are all these files?
-
-* The src/ directory contains the source of libjass. They are TypeScript files and get compiled into JavaScript for the browser using the TypeScript compiler.
-
-* build.js is the build script. The build command will use this script to build libjass.js. The build/ directory contains other files used for the build.
-
-* The tests/ directory contains unit and functional tests.
-
-* The lib/ directory contains libjass.js and libjass.css. You will need to deploy these to your website.
-
-
-### How do I use libjass?
-
-The API documentation is linked in the Links section below. Here's an overview:
-
-* The [ASS.fromUrl()](http://arnavion.github.io/libjass/api.xhtml#libjass.ASS.fromUrl) function takes in a URL to an ASS script and returns a promise that resolves to an [ASS](http://arnavion.github.io/libjass/api.xhtml#libjass.ASS) object. This ASS object represents the script properties, the line styles and dialogue lines in it. Alternatively, you can use [ASS.fromString()](http://arnavion.github.io/libjass/api.xhtml#libjass.ASS.fromString) to convert a string of the script contents into an ASS object.
-
-* Next, you initialize a renderer to render the subtitles. libjass ships with an easy-to-use renderer, the [DefaultRenderer](http://arnavion.github.io/libjass/api.xhtml#libjass.renderers.DefaultRenderer). It uses information from the ASS object to build up a series of div elements around the video tag. There is a wrapper (.libjass-subs) containing div's corresponding to the layers in the ASS script, and each layer has div's corresponding to the 9 alignment directions. libjass.css contains styles for these div's to render them at the correct location.
-
-* The renderer uses [window.requestAnimationFrame](https://developer.mozilla.org/en-US/docs/Web/API/window.requestAnimationFrame) as a source of timer ticks. In each tick, it determines the set of dialogues to be shown at the current video time, renders each of them as a div, and appendChild's the div into the appropriate layer+alignment div.
-
-* The renderer can be told to dynamically change the size of the subtitles based on user input by calling [WebRenderer.resize()](http://arnavion.github.io/libjass/api.xhtml#libjass.renderers.WebRenderer.resize)
-
-* Lastly, the renderer contains an implementation of preloading fonts before playing the video. It uses a map of font names to URLs - this map can be conveniently created from a CSS file containing @font-face rules using [RendererSettings.makeFontMapFromStyleElement()](http://arnavion.github.io/libjass/api.xhtml#libjass.renderers.RendererSettings.makeFontMapFromStyleElement)
-
-* For an example of using libjass, check out [the demo.](http://arnavion.github.io/libjass/demo/index.xhtml) It has comments explaining basic usage and pointers to some advanced usage.
-
-
-### What browser and JavaScript features does libjass need?
-
-* libjass uses some ES5 features like getters and setters (via Object.defineProperty), and assumptions like the behavior of parseInt with leading zeros. It cannot be used with an ES3 environment.
-
-* libjass will use ES6 Set, Map and Promise if they're available on the global object. If they're not present, it will use its own minimal internal implementations. If you have implementations of these that you would like libjass to use but don't want to register them on the global object, you can provide them to libjass specifically by setting the [libjass.Set](http://arnavion.github.io/libjass/api.xhtml#libjass.Set), [libjass.Map](http://arnavion.github.io/libjass/api.xhtml#libjass.Map) and [libjass.Promise](http://arnavion.github.io/libjass/api.xhtml#libjass.Promise) properties.
-
-* [AutoClock](http://arnavion.github.io/libjass/api.xhtml#libjass.renderers.AutoClock) and [VideoClock](http://arnavion.github.io/libjass/api.xhtml#libjass.renderers.VideoClock) use [window.requestAnimationFrame](https://developer.mozilla.org/en-US/docs/Web/API/window/requestAnimationFrame) to generate clock ticks.
-
-* [WebRenderer](http://arnavion.github.io/libjass/api.xhtml#libjass.renderers.WebRenderer) and [DefaultRenderer](http://arnavion.github.io/libjass/api.xhtml#libjass.renderers.DefaultRenderer) use [SVG filter effects for HTML](http://caniuse.com/#feat=svg-html) to render outlines and blur. This feature is not available on all browsers, so you can tell them to fall back to more widely available CSS methods by setting the [RendererSettings.enableSvg](http://arnavion.github.io/libjass/api.xhtml#libjass.renderers.RendererSettings.enableSvg) property to false.
-
-* WebRenderer and DefaultRenderer use [CSS3 animations](http://caniuse.com/#feat=css-animation) for effects like \mov and \fad.
-
-* Using fonts attached to the script requires [ES6 typed arrays](http://caniuse.com/#feat=typedarrays) (ArrayBuffer, DataView, Uint8Array, etc).
-
-
-### Can I use libjass in node?
-
-libjass's parser works in node. Entire scripts can be parsed via [ASS.fromString()](http://arnavion.github.io/libjass/api.xhtml#libjass.ASS.fromString)
-
-```javascript
-> var libjass = require("libjass")
-undefined
-> var ass; libjass.ASS.fromString(fs.readFileSync("mysubs.ass", "utf8")).then(function (result) { ass = result; })
-{}
-> ass.properties.resolutionX
-1280
-> ass.dialogues.length
-9
-> ass.dialogues[0].toString()
-'#0 [646.460-652.130] {\\fad(200,0)}Sapien rhoncus, suscipit posuere in nunc pellentesque'
-> var parts = ass.dialogues[0].parts
-undefined
-> parts.length
-2
-> parts[0] instanceof libjass.parts.Fade
-true
-> parts[0].toString()
-'Fade { start: 0.2, end: 0 }'
-```
-
-[libjass.parser.parse](http://arnavion.github.io/libjass/api.xhtml#libjass.parser.parse) parses the first parameter using the second parameter as the rule name. For example, the [dialogueParts](http://arnavion.github.io/libjass/api.xhtml#./parser/parse.ParserRun.parse_dialogueParts) rule can be used to get an array of [libjass.parts](http://arnavion.github.io/libjass/api.xhtml#libjass.parts) objects that represent the parts of an ASS dialogue line.
-
-```javascript
-> var parts = libjass.parser.parse("{\\an8}Are {\\i1}you{\\i0} the one who stole the clock?!", "dialogueParts")
-undefined
-> parts.join(" ")
-'Alignment { value: 8 } Text { value: Are  } Italic { value: true } Text { value: you } Italic { value: false } Text { value:  the one who stole the clock?! }'
-> parts.length
-6
-> parts[0].toString()
-'Alignment { value: 8 }'
-> parts[0] instanceof libjass.parts.Alignment
-true
-> parts[0].value
-8
-```
-
-The rule names are derived from the methods on the [ParserRun class](http://arnavion.github.io/libjass/api.xhtml#./parser/parse.ParserRun).
-
-See the tests, particularly the ones in tests/unit/miscellaneous.js, for examples.
-
-
-### Can I contribute?
-
-Yes! Feature requests, suggestions, bug reports and pull requests are welcome! I'm especially looking for details and edge-cases of the ASS syntax that libjass doesn't support.
-
-You can also join the IRC channel in the links section below and ask any questions.
-
-
-### Supported features
-
-* Styles: Italic, Bold, Underline, StrikeOut, FontName, FontSize, ScaleX, ScaleY, Spacing, PrimaryColor, OutlineColor, BackColor, Outline, Shadow, Alignment, MarginL, MarginR, MarginV
-* Tags: \i, \b, \u, \s, \bord, \xbord, \ybord, \shad, \xshad, \yshad, \be, \blur, \fn, \fs, \fscx, \fscy, \fsp, \frx, \fry, \frz, \fr, \fax, \fay, \c, \1c, \3c, \4c, \alpha, \1a, \3a, \4a, \an, \a, \k, \q, \r, \pos, \move, \fad, \fade, \t (experimental), \p
-* Custom fonts, using CSS web fonts.
-
-
-### Known issues
-
-* Unsupported tags: \fe, \2c, \2a, \K, \kf, \ko, \org, \clip, \iclip
-* \an4, \an5, \an6 aren't positioned correctly.
-* Smart line wrapping is not supported. Such lines are rendered as [wrapping style 1 (end-of-line wrapping).](http://docs.aegisub.org/3.0/ASS_Tags/#wrapstyle)
-* Lines with multiple rotations aren't rotated the same as VSFilter or libass. See [#14](https://github.com/Arnavion/libjass/issues/14)
-- Desktop renderers include borders when calculating space between adjacent lines. libjass doesn't.

-/**
- * An implementation of {@link libjass.renderers.Clock} that automatically ticks and generates {@link libjass.renderers.ClockEvent}s according to the state of an external driver.

- * For example, if you're using libjass to render subtitles on a canvas with your own video controls, these video controls will function as the driver to this AutoClock.
- * It would call {@link libjass.renderers.AutoClock.play}, {@link libjass.renderers.AutoClock.pause}, etc. when the user pressed the corresponding video controls.

- * The difference from ManualClock is that AutoClock does not require the driver to call something like {@link libjass.renderers.ManualClock.tick}. Instead it keeps its
- * own time with a high-resolution requestAnimationFrame-based timer.
- *
- * If using libjass with a <video> element, consider using {@link libjass.renderers.VideoClock} that uses the video element as a driver.
- *
- * @param {function():number} getCurrentTime A callback that will be invoked to get the current time of the external driver.
- * @param {number} autoPauseAfter If two calls to getCurrentTime are more than autoPauseAfter milliseconds apart but return the same time, then the external driver will be
- * considered to have paused.

-# videojs-ass
-
-Add **Advanced SubStation Alpha (ASS)** subtitles support to
-[videojs](https://github.com/videojs/video.js) using the
-[libjass](https://github.com/Arnavion/libjass) library.
-
-Check out the demo
-[here](https://sunnyli.github.io/videojs-ass/example.html)
-
-
-## Install
-
-For plugin that supports videojs v5.x install using either:
-
-- `bower install videojs-ass`
-
-or
-
-- `npm install videojs-ass`
-
-For videojs v4:
-
-Just specify version to be within:
-
-```
-"videojs-ass": ">=0.3.0 < 0.5.0"
-```
-for bower or npm whichever you prefer using.
-
-
-## Usage
-
-Initialize the `ass` plugin with the `src` field like the following:
-
-```
-videojs('player_id', {
-  plugins: {
-    ass: {
-      src: 'subs/subtitles.ass'
-    }
-  }
-}
-```
-
-| Option      | Default       | Description                                                |
-| ----------- | ------------- | ---------------------------------------------------------- |
-| src         | -<sup>1</sup> | `.ass` / `.ssa` source.                                    |
-| label       | -<sup>2</sup> | subtitle track label that shows up in the subtitles picker |
-| delay       | 0<sup>3</sup> | delay subtitle rendering by the specified value in seconds |
-| rate        | 1             | subtitle update speed relative to video playback rate      |
-| enableSvg   | true          | see [here][svg-effects] regarding SVG filter               |
-| fontMap     | -             | see [here][font-map] regarding using custom web fonts      |
-| fontMapById | -             | alternate to above, takes id and runs [this][font-map-el]  |
-| videoWidth  | -<sup>3</sup> | metadata to assist in determining the optimal (cont below) |
-| videoHeight | -<sup>3</sup> | (cont) subtitle letterboxing ratio                         |
-
-**Footnotes:**
-
-1. This property is required!
-2. Has fallback values but you should provide a better label.
-3. Value can be negative
-4. Generally, you should set these values when using external videojs providers
-   as they might not expose the video dimensions to the player.

+   *    00000011 = length 7 because there are 6 zeros before a 1.
+   *
+   * 2. The bits used for length are removed from the first byte

+   * Primary timing in VHS goes by video. This is different from most media players, as
+   * audio is more often used as the primary timing source. For the foreseeable future, VHS
+   * will continue to use video as the primary timing source, due to the current logic and
+   * expectations built around it.
+
+   * Since the timing follows video, in order to maintain sync, the video loader is
+   * responsible for setting both audio and video source buffer timestamp offsets.
+   *
+   * Setting different values for audio and video source buffers could lead to
+   * desyncing. The following examples demonstrate some of the situations where this
+   * distinction is important. Note that all of these cases involve demuxed content. When
+   * content is muxed, the audio and video are packaged together, therefore syncing
+   * separate media playlists is not an issue.
+   *
+   * CASE 1: Audio prepares to load a new timeline before video:
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:                     ^
+   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Video Loader              ^
+   *
+   * In the above example, the audio loader is preparing to load the 6th segment, the first
+   * after a discontinuity, while the video loader is still loading the 5th segment, before
+   * the discontinuity.
+   *
+   * If the audio loader goes ahead and loads and appends the 6th segment before the video
+   * loader crosses the discontinuity, then when appended, the 6th audio segment will use
+   * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,
+   * the audio loader must provide the audioAppendStart value to trim the content in the
+   * transmuxer, and that value relies on the audio timestamp offset. Since the audio
+   * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the
+   * segment until that value is provided.
+   *
+   * CASE 2: Video prepares to load a new timeline before audio:
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:             ^
+   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Video Loader                      ^
+   *
+   * In the above example, the video loader is preparing to load the 6th segment, the first
+   * after a discontinuity, while the audio loader is still loading the 5th segment, before
+   * the discontinuity.
+   *
+   * If the video loader goes ahead and loads and appends the 6th segment, then once the
+   * segment is loaded and processed, both the video and audio timestamp offsets will be
+   * set, since video is used as the primary timing source. This is to ensure content lines
+   * up appropriately, as any modifications to the video timing are reflected by audio when
+   * the video loader sets the audio and video timestamp offsets to the same value. However,
+   * setting the timestamp offset for audio before audio has had a chance to change
+   * timelines will likely lead to desyncing, as the audio loader will append segment 5 with
+   * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.
+   *
+   * CASE 3: When seeking, audio prepares to load a new timeline before video
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:           ^
+   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Video Loader            ^
+   *
+   * In the above example, both audio and video loaders are loading segments from timeline
+   * 0, but imagine that the seek originated from timeline 1.
+   *
+   * When seeking to a new timeline, the timestamp offset will be set based on the expected
+   * segment start of the loaded video segment. In order to maintain sync, the audio loader
+   * must wait for the video loader to load its segment and update both the audio and video
+   * timestamp offsets before it may load and append its own segment. This is the case
+   * whether the seek results in a mismatched segment request (e.g., the audio loader
+   * chooses to load segment 3 and the video loader chooses to load segment 4) or the
+   * loaders choose to load the same segment index from each playlist, as the segments may
+   * not be aligned perfectly, even for matching segment indexes.

+   * Primary timing in VHS goes by video. This is different from most media players, as
+   * audio is more often used as the primary timing source. For the foreseeable future, VHS
+   * will continue to use video as the primary timing source, due to the current logic and
+   * expectations built around it.
+
+   * Since the timing follows video, in order to maintain sync, the video loader is
+   * responsible for setting both audio and video source buffer timestamp offsets.
+   *
+   * Setting different values for audio and video source buffers could lead to
+   * desyncing. The following examples demonstrate some of the situations where this
+   * distinction is important. Note that all of these cases involve demuxed content. When
+   * content is muxed, the audio and video are packaged together, therefore syncing
+   * separate media playlists is not an issue.
+   *
+   * CASE 1: Audio prepares to load a new timeline before video:
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:                     ^
+   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Video Loader              ^
+   *
+   * In the above example, the audio loader is preparing to load the 6th segment, the first
+   * after a discontinuity, while the video loader is still loading the 5th segment, before
+   * the discontinuity.
+   *
+   * If the audio loader goes ahead and loads and appends the 6th segment before the video
+   * loader crosses the discontinuity, then when appended, the 6th audio segment will use
+   * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,
+   * the audio loader must provide the audioAppendStart value to trim the content in the
+   * transmuxer, and that value relies on the audio timestamp offset. Since the audio
+   * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the
+   * segment until that value is provided.
+   *
+   * CASE 2: Video prepares to load a new timeline before audio:
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:             ^
+   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Video Loader                      ^
+   *
+   * In the above example, the video loader is preparing to load the 6th segment, the first
+   * after a discontinuity, while the audio loader is still loading the 5th segment, before
+   * the discontinuity.
+   *
+   * If the video loader goes ahead and loads and appends the 6th segment, then once the
+   * segment is loaded and processed, both the video and audio timestamp offsets will be
+   * set, since video is used as the primary timing source. This is to ensure content lines
+   * up appropriately, as any modifications to the video timing are reflected by audio when
+   * the video loader sets the audio and video timestamp offsets to the same value. However,
+   * setting the timestamp offset for audio before audio has had a chance to change
+   * timelines will likely lead to desyncing, as the audio loader will append segment 5 with
+   * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.
+   *
+   * CASE 3: When seeking, audio prepares to load a new timeline before video
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:           ^
+   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Video Loader            ^
+   *
+   * In the above example, both audio and video loaders are loading segments from timeline
+   * 0, but imagine that the seek originated from timeline 1.
+   *
+   * When seeking to a new timeline, the timestamp offset will be set based on the expected
+   * segment start of the loaded video segment. In order to maintain sync, the audio loader
+   * must wait for the video loader to load its segment and update both the audio and video
+   * timestamp offsets before it may load and append its own segment. This is the case
+   * whether the seek results in a mismatched segment request (e.g., the audio loader
+   * chooses to load segment 3 and the video loader chooses to load segment 4) or the
+   * loaders choose to load the same segment index from each playlist, as the segments may
+   * not be aligned perfectly, even for matching segment indexes.

+ * Primary timing in VHS goes by video. This is different from most media players, as
+ * audio is more often used as the primary timing source. For the foreseeable future, VHS
+ * will continue to use video as the primary timing source, due to the current logic and
+ * expectations built around it.
+
+ * Since the timing follows video, in order to maintain sync, the video loader is
+ * responsible for setting both audio and video source buffer timestamp offsets.
+ *
+ * Setting different values for audio and video source buffers could lead to
+ * desyncing. The following examples demonstrate some of the situations where this
+ * distinction is important. Note that all of these cases involve demuxed content. When
+ * content is muxed, the audio and video are packaged together, therefore syncing
+ * separate media playlists is not an issue.
+ *
+ * CASE 1: Audio prepares to load a new timeline before video:
+ *
+ * Timeline:       0                 1
+ * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Audio Loader:                     ^
+ * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Video Loader              ^
+ *
+ * In the above example, the audio loader is preparing to load the 6th segment, the first
+ * after a discontinuity, while the video loader is still loading the 5th segment, before
+ * the discontinuity.
+ *
+ * If the audio loader goes ahead and loads and appends the 6th segment before the video
+ * loader crosses the discontinuity, then when appended, the 6th audio segment will use
+ * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,
+ * the audio loader must provide the audioAppendStart value to trim the content in the
+ * transmuxer, and that value relies on the audio timestamp offset. Since the audio
+ * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the
+ * segment until that value is provided.
+ *
+ * CASE 2: Video prepares to load a new timeline before audio:
+ *
+ * Timeline:       0                 1
+ * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Audio Loader:             ^
+ * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Video Loader                      ^
+ *
+ * In the above example, the video loader is preparing to load the 6th segment, the first
+ * after a discontinuity, while the audio loader is still loading the 5th segment, before
+ * the discontinuity.
+ *
+ * If the video loader goes ahead and loads and appends the 6th segment, then once the
+ * segment is loaded and processed, both the video and audio timestamp offsets will be
+ * set, since video is used as the primary timing source. This is to ensure content lines
+ * up appropriately, as any modifications to the video timing are reflected by audio when
+ * the video loader sets the audio and video timestamp offsets to the same value. However,
+ * setting the timestamp offset for audio before audio has had a chance to change
+ * timelines will likely lead to desyncing, as the audio loader will append segment 5 with
+ * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.
+ *
+ * CASE 3: When seeking, audio prepares to load a new timeline before video
+ *
+ * Timeline:       0                 1
+ * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Audio Loader:           ^
+ * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Video Loader            ^
+ *
+ * In the above example, both audio and video loaders are loading segments from timeline
+ * 0, but imagine that the seek originated from timeline 1.
+ *
+ * When seeking to a new timeline, the timestamp offset will be set based on the expected
+ * segment start of the loaded video segment. In order to maintain sync, the audio loader
+ * must wait for the video loader to load its segment and update both the audio and video
+ * timestamp offsets before it may load and append its own segment. This is the case
+ * whether the seek results in a mismatched segment request (e.g., the audio loader
+ * chooses to load segment 3 and the video loader chooses to load segment 4) or the
+ * loaders choose to load the same segment index from each playlist, as the segments may

+ * Primary timing in VHS goes by video. This is different from most media players, as
+ * audio is more often used as the primary timing source. For the foreseeable future, VHS
+ * will continue to use video as the primary timing source, due to the current logic and
+ * expectations built around it.
+
+ * Since the timing follows video, in order to maintain sync, the video loader is
+ * responsible for setting both audio and video source buffer timestamp offsets.
+ *
+ * Setting different values for audio and video source buffers could lead to
+ * desyncing. The following examples demonstrate some of the situations where this
+ * distinction is important. Note that all of these cases involve demuxed content. When
+ * content is muxed, the audio and video are packaged together, therefore syncing
+ * separate media playlists is not an issue.
+ *
+ * CASE 1: Audio prepares to load a new timeline before video:
+ *
+ * Timeline:       0                 1
+ * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Audio Loader:                     ^
+ * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Video Loader              ^
+ *
+ * In the above example, the audio loader is preparing to load the 6th segment, the first
+ * after a discontinuity, while the video loader is still loading the 5th segment, before
+ * the discontinuity.
+ *
+ * If the audio loader goes ahead and loads and appends the 6th segment before the video
+ * loader crosses the discontinuity, then when appended, the 6th audio segment will use
+ * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,
+ * the audio loader must provide the audioAppendStart value to trim the content in the
+ * transmuxer, and that value relies on the audio timestamp offset. Since the audio
+ * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the
+ * segment until that value is provided.
+ *
+ * CASE 2: Video prepares to load a new timeline before audio:
+ *
+ * Timeline:       0                 1
+ * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Audio Loader:             ^
+ * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Video Loader                      ^
+ *
+ * In the above example, the video loader is preparing to load the 6th segment, the first
+ * after a discontinuity, while the audio loader is still loading the 5th segment, before
+ * the discontinuity.
+ *
+ * If the video loader goes ahead and loads and appends the 6th segment, then once the
+ * segment is loaded and processed, both the video and audio timestamp offsets will be
+ * set, since video is used as the primary timing source. This is to ensure content lines
+ * up appropriately, as any modifications to the video timing are reflected by audio when
+ * the video loader sets the audio and video timestamp offsets to the same value. However,
+ * setting the timestamp offset for audio before audio has had a chance to change
+ * timelines will likely lead to desyncing, as the audio loader will append segment 5 with
+ * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.
+ *
+ * CASE 3: When seeking, audio prepares to load a new timeline before video
+ *
+ * Timeline:       0                 1
+ * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Audio Loader:           ^
+ * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+ * Video Loader            ^
+ *
+ * In the above example, both audio and video loaders are loading segments from timeline
+ * 0, but imagine that the seek originated from timeline 1.
+ *
+ * When seeking to a new timeline, the timestamp offset will be set based on the expected
+ * segment start of the loaded video segment. In order to maintain sync, the audio loader
+ * must wait for the video loader to load its segment and update both the audio and video
+ * timestamp offsets before it may load and append its own segment. This is the case
+ * whether the seek results in a mismatched segment request (e.g., the audio loader
+ * chooses to load segment 3 and the video loader chooses to load segment 4) or the
+ * loaders choose to load the same segment index from each playlist, as the segments may

+   * Primary timing in VHS goes by video. This is different from most media players, as
+   * audio is more often used as the primary timing source. For the foreseeable future, VHS
+   * will continue to use video as the primary timing source, due to the current logic and
+   * expectations built around it.
+
+   * Since the timing follows video, in order to maintain sync, the video loader is
+   * responsible for setting both audio and video source buffer timestamp offsets.
+   *
+   * Setting different values for audio and video source buffers could lead to
+   * desyncing. The following examples demonstrate some of the situations where this
+   * distinction is important. Note that all of these cases involve demuxed content. When
+   * content is muxed, the audio and video are packaged together, therefore syncing
+   * separate media playlists is not an issue.
+   *
+   * CASE 1: Audio prepares to load a new timeline before video:
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:                     ^
+   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Video Loader              ^
+   *
+   * In the above example, the audio loader is preparing to load the 6th segment, the first
+   * after a discontinuity, while the video loader is still loading the 5th segment, before
+   * the discontinuity.
+   *
+   * If the audio loader goes ahead and loads and appends the 6th segment before the video
+   * loader crosses the discontinuity, then when appended, the 6th audio segment will use
+   * the timestamp offset from timeline 0. This will likely lead to desyncing. In addition,
+   * the audio loader must provide the audioAppendStart value to trim the content in the
+   * transmuxer, and that value relies on the audio timestamp offset. Since the audio
+   * timestamp offset is set by the video (main) loader, the audio loader shouldn't load the
+   * segment until that value is provided.
+   *
+   * CASE 2: Video prepares to load a new timeline before audio:
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:             ^
+   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Video Loader                      ^
+   *
+   * In the above example, the video loader is preparing to load the 6th segment, the first
+   * after a discontinuity, while the audio loader is still loading the 5th segment, before
+   * the discontinuity.
+   *
+   * If the video loader goes ahead and loads and appends the 6th segment, then once the
+   * segment is loaded and processed, both the video and audio timestamp offsets will be
+   * set, since video is used as the primary timing source. This is to ensure content lines
+   * up appropriately, as any modifications to the video timing are reflected by audio when
+   * the video loader sets the audio and video timestamp offsets to the same value. However,
+   * setting the timestamp offset for audio before audio has had a chance to change
+   * timelines will likely lead to desyncing, as the audio loader will append segment 5 with
+   * a timestamp intended to apply to segments from timeline 1 rather than timeline 0.
+   *
+   * CASE 3: When seeking, audio prepares to load a new timeline before video
+   *
+   * Timeline:       0                 1
+   * Audio Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Audio Loader:           ^
+   * Video Segments: 0 1 2 3 4 5 DISCO 6 7 8 9
+   * Video Loader            ^
+   *
+   * In the above example, both audio and video loaders are loading segments from timeline
+   * 0, but imagine that the seek originated from timeline 1.
+   *
+   * When seeking to a new timeline, the timestamp offset will be set based on the expected
+   * segment start of the loaded video segment. In order to maintain sync, the audio loader
+   * must wait for the video loader to load its segment and update both the audio and video
+   * timestamp offsets before it may load and append its own segment. This is the case
+   * whether the seek results in a mismatched segment request (e.g., the audio loader
+   * chooses to load segment 3 and the video loader chooses to load segment 4) or the
+   * loaders choose to load the same segment index from each playlist, as the segments may
+   * not be aligned perfectly, even for matching segment indexes.
