| # ffmpeg.wasm plugin | ||
|
|
||
| [FFmpeg](https://ffmpeg.org) is the Swiss-army knife of media transcoding. This plugin allows | ||
| you to run FFmpeg in the browser and perform on-the-fly transcoding of recorded data. | ||
|
|
||
| This plugin uses [ffmpeg.wasm](https://github.com/ffmpegwasm/ffmpeg.wasm) that provides a | ||
| Webassembly / Javascript port of FFmpeg. | ||
|
|
||
| ## Example | ||
|
|
||
| - [online demo](https://collab-project.github.io/videojs-record/demo/video-only-ffmpegwasm.html) | ||
| - [demo source](https://github.com/collab-project/videojs-record/blob/master/examples/plugins/video-only-ffmpegwasm.html) | ||
|
|
||
| ## Usage | ||
|
|
||
| Install the library: | ||
|
|
||
| ```console | ||
| npm install --save @ffmpeg/ffmpeg @ffmpeg/core | ||
| ``` | ||
|
|
||
| Include the library and place it before any other scripts: | ||
|
|
||
| ```html | ||
| <script src="@ffmpeg/ffmpeg/dist/ffmpeg.min.js"></script> | ||
| ``` | ||
|
|
||
| Import the plugin: | ||
|
|
||
| ```javascript | ||
| import FFmpegWasmEngine from 'videojs-record/dist/plugins/videojs.record.ffmpeg-wasm.js'; | ||
| ``` | ||
|
|
||
| And configure the `ffmpeg.wasm` `convertEngine`. For example: | ||
|
|
||
| ```javascript | ||
| record: { | ||
| audio: true, | ||
| video: true, | ||
| maxLength: 20, | ||
| debug: true, | ||
| // enable ffmpeg.wasm plugin | ||
| convertEngine: 'ffmpeg.wasm', | ||
| convertWorkerURL: '../../node_modules/@ffmpeg/core/dist/ffmpeg-core.js', | ||
| // convert recorded data to MP4 (and copy over audio data without encoding) | ||
| convertOptions: ['-c:v', 'libx264', '-preset', 'slow', '-crf', '22', '-c:a', 'copy', '-f', 'mp4'], | ||
| // specify output mime-type | ||
| pluginLibraryOptions: { | ||
| outputType: 'video/mp4' | ||
| } | ||
| } | ||
| ``` | ||
|
|
||
| ## Options | ||
|
|
||
| Options for this plugin: | ||
|
|
||
| | Option | Value | Description | | ||
| | --- | --- | --- | | ||
| | `convertEngine` | `ffmpeg.wasm` | Enables the plugin. | | ||
| | `convertOptions` | `['-f', 'mp3', '-codec:a', 'libmp3lame', '-qscale:a', '2']` | Array of arguments for FFmpeg. | | ||
| | `pluginLibraryOptions` | `{outputType: 'video/mp4'}` | Specify output mime-type and other options. | | ||
| | `convertWorkerURL` | `/path/to/@ffmpeg/core/dist/ffmpeg-core.js` | Specify encoding worker. | |
