|

- `keyFrameInterval`: The maximum interval in seconds between two adjacent key frames. Defaults to 5 seconds. More frequent key frames improve seeking behavior but increase file size. When using multiple video tracks, this value should be set to the same value for all tracks.
|
||||
- `fullCodecString`: Allows you to optionally specify the full codec string used by the video encoder, as specified in the [WebCodecs Codec Registry](https://www.w3.org/TR/webcodecs-codec-registry/). For example, you may set it to `'avc1.42001f'` when using AVC. Keep in mind that the codec string must still match the codec specified in `codec`. If you don't set this field, a codec string will be generated automatically.
|

- `onEncodedPacket`: Called for each successfully encoded packet. Useful for determining encoding progress.

Browsers typically have no support for MP3 encoding in their WebCodecs implementations. Given the ubiquity of the format, this extension package provides an MP3 encoder for use with [Mediabunny](https://github.com/Vanilagy/mediabunny). It is implemented using Mediabunny's [custom coder API](https://mediabunny.dev/guide/supported-formats-and-codecs#custom-coders) and uses a highly-performant WASM build of the [LAME MP3 Encoder](https://lame.sourceforge.io/) under the hood.
