-
-## Collaborator
-If you are a collaborator, we have a guide on how to [release](./COLLABORATOR_GUIDE.md#releasing) the project.
-
-## Contributing
-If you are interested in contributing to `mux.js`, take a look at our docs on [streams](/docs/streams.md) to get started.
-
-## Options
-
-The exported `muxjs` object contains the following modules:
-
-- [codecs](#codecs): a module for handling various codecs
-- [mp4](#mp4): a module for handling ISOBMFF MP4 boxes
-- [flv](#flv): a module for handling Flash content
-- [mp2t](#mp2t): a module for handling MPEG 2 Transport Stream content
-
-### Codecs
-
-#### Adts
-
-`muxjs.codecs.Adts`
-
-The Adts(Audio Data Transport Stream) module handles audio data, specifically AAC. Includes an `AdtsStream` that takes ADTS audio and parses out AAC frames to pass on to the next Stream component in a pipeline.
-
-#### h264
-
-`muxjs.codecs.h264`
-
-The h264 module Handles H264 bitstreams, including a `NalByteStream` and `H264Stream` to parse out NAL Units and pass them on to the next Stream component in a pipeline.
-
-### mp4
-
-#### MP4 Generator
-
-`muxjs.mp4.generator`
-
-The MP4 Generator module contains multiple functions that can be used to generate fragmented MP4s (fmp4s) that can be used in MSE.
-
-#### MP4 Probe
-
-`muxjs.mp4.probe`
-
-The MP4 Probe contains basic utilites that can be used to parse metadata about an MP4 segment. Some examples include: `timescale` and getting the base media decode time of a fragment in seconds.
-
-#### MP4 Transmuxer
-
-`muxjs.mp4.Transmuxer`
-
-Takes MPEG2-TS segments and transmuxes them into fmp4 segments.
-
-Options:
-
-##### baseMediaDecodeTime
-
-Type: `number`
-
-Default: `0`
-
-The Base Media Decode Time of the first segment to be passed into the transmuxer.
-
-##### keepOriginalTimestamps
-
-Type: `boolean`
-
-Default: `false`
-
-The default behavior of the MP4 Transmuxer is to rewrite the timestamps of media segments to ensure that they begin at `0` on the media timeline in MSE. To avoid this behavior, you may set this option to `true`.
-
-**Note**: This will affect behavior of captions and metadata, and these may not align with audio and video without additional manipulation of timing metadata.
-
-##### remux
-
-Type: `boolean`
-
-Default: `true`
-
-Set to `true` to remux audio and video into a single MP4 segment.
-
-#### CaptionParser
-
-`muxjs.mp4.CaptionParser`
-
-This module reads CEA-608 captions out of FMP4 segments.
-
-#### Tools
-
-`muxjs.mp4.tools`
-
-This module includes utilities to parse MP4s into an equivalent javascript object, primarily for debugging purposes.
-
-### flv
-
-#### Transmuxer
-
-`muxjs.flv.Transmuxer`
-
-Takes MPEG2-TS segments and transmuxes them into FLV segments. This module is in maintenance mode and will not have further major development.
-
-#### Tools
-
-`muxjs.flv.tools`
-
-This module includes utilities to parse FLV tags into an equivalent javascript object, primarily for debugging purposes.

-Contains Streams specifically to handle MPEG2-TS data, for example `ElementaryStream` and `TransportPacketStream`. This is used in the MP4 module.
-
-#### CaptionStream
-
-`muxjs.mp2t.CaptionStream`
-
-Handles the bulk of parsing CEA-608 captions out of MPEG2-TS segments.
-
-#### Tools
-
-`muxjs.mp2t.tools`
-
-This module contains utilities to parse basic timing information out of MPEG2-TS segments.
-
-## Background
-
-### fMP4
-Before making use of the Transmuxer it is best to understand the structure of a fragmented MP4 (fMP4).
-
-fMP4's are structured in *boxes* as described in the ISOBMFF spec.
-
-For a basic fMP4 to be valid it needs to have the following boxes:
-
-1) ftyp (File Type Box)
-2) moov (Movie Header Box)
-3) moof (Movie Fragment Box)
-4) mdat (Movie Data Box)
-
-Every fMP4 stream needs to start with an `ftyp` and `moov` box which is then followed by many `moof` and `mdat` pairs.
-
-It is important to understand that when you append your first segment to [Media Source Extensions](https://www.w3.org/TR/media-source/) that this segment will need to start with an `ftyp` and `moov` followed by a `moof` and `mdat`. A segment containing a `ftyp` and `moov` box is often referred to as an Initialization Segment(`init`) segment, and segments containing `moof` and `mdat` boxes, referring to media itself as Media Segments.
-
-If you would like to see a clearer representation of your fMP4 you can use the `muxjs.mp4.tools.inspect()` method.
-
-## MPEG2-TS to fMP4 Transmuxer
-### Diagram
-
-
-## Usage Examples
-
-### Basic Usage
-
-To make use of the Transmuxer method you will need to push data to the transmuxer you have created.
-
-Feed in `Uint8Array`s of an MPEG-2 transport stream, get out a fragmented MP4.
-
-Lets look at a very basic representation of what needs to happen the first time you want to append a fMP4 to an MSE buffer.
-
-```js
-// Create your transmuxer:
-// initOptions is optional and can be omitted at this time.
-var transmuxer = new muxjs.mp4.Transmuxer(initOptions);
-
-// Create an event listener which will be triggered after the transmuxer processes data:
-// 'data' events signal a new fMP4 segment is ready
-transmuxer.on('data', function (segment) {
- // This code will be executed when the event listener is triggered by a Transmuxer.push() method execution.
- // Create an empty Uint8Array with the summed value of both the initSegment and data byteLength properties.
- let data = new Uint8Array(segment.initSegment.byteLength + segment.data.byteLength);
-
- // Add the segment.initSegment (ftyp/moov) starting at position 0
- data.set(segment.initSegment, 0);
-
- // Add the segment.data (moof/mdat) starting after the initSegment
- data.set(segment.data, segment.initSegment.byteLength);
-
- // Uncomment this line below to see the structure of your new fMP4
- // console.log(muxjs.mp4.tools.inspect(data));
-
- // Add your brand new fMP4 segment to your MSE Source Buffer
- sourceBuffer.appendBuffer(data);
-});
-
-// When you push your starting MPEG-TS segment it will cause the 'data' event listener above to run.
-// It is important to push after your event listener has been defined.
-transmuxer.push(transportStreamSegment);
-transmuxer.flush();
-```
-
-Above we are adding in the `initSegment` (ftyp/moov) to our data array before appending to the MSE Source Buffer.
-
-This is required for the first part of data we append to the MSE Source Buffer, but we will omit the `initSegment` for our remaining chunks (moof/mdat)'s of video we are going to append to our Source Buffer.
-
-In the case of appending additional segments after your first segment we will just need to use the following event listener anonymous function:
-
-```js
-transmuxer.on('data', function(segment){
- sourceBuffer.appendBuffer(new Uint8Array(segment.data));
-});
-```
-
-Here we put all of this together in a very basic example player.
-
-```html
-
-
- Basic Transmuxer Test
-
-
-
-
-
-
-
-```
-*NOTE: This player is only for example and should not be used in production.*
-
-### Metadata
-
-The transmuxer can also parse out supplementary video data like timed ID3 metadata and CEA-608 captions.
-You can find both attached to the data event object:
-
-```js
-transmuxer.on('data', function (segment) {
- // create a metadata text track cue for each ID3 frame:
- segment.metadata.frames.forEach(function(frame) {
- metadataTextTrack.addCue(new VTTCue(time, time, frame.value));
- });
- // create a VTTCue for all the parsed CEA-608 captions:>
- segment.captions.forEach(function(cue) {
- captionTextTrack.addCue(new VTTCue(cue.startTime, cue.endTime, cue.text));
- });
-});
-```
-
-### MP4 Inspector
-
-Parse MP4s into javascript objects or a text representation for display or debugging:
-
-```js
-// drop in a Uint8Array of an MP4:
-var parsed = muxjs.mp4.tools.inspect(bytes);
-// dig into the boxes:
-console.log('The major brand of the first box:', parsed[0].majorBrand);
-// print out the structure of the MP4:
-document.body.appendChild(document.createTextNode(muxjs.textifyMp4(parsed)));
-```
-The MP4 inspector is used extensively as a debugging tool for the transmuxer. You can see it in action by cloning the project and opening [the debug page](https://github.com/videojs/mux.js/blob/master/debug/index.html) in your browser.

-// proper Unicode equivalent. The first one-byte key is just a
-// non-standard character code. The two-byte keys that follow are
-// the extended CEA708 character codes, along with the preceding
-// 0x10 extended character byte to distinguish these codes from
-// non-extended character codes. Every CEA708 character code that
-// is not in this object maps directly to a standard unicode
-// character code.
-// The transparent space and non-breaking transparent space are
-// technically not fully supported since there is no code to
-// make them transparent, so they have normal non-transparent
-// stand-ins.
-// The special closed caption (CC) character isn't a standard
-// unicode character, so a fairly similar unicode character was
-// chosen in it's place.
