Function of 02.

MediaStreamTrack Insertable Streams source trial

This API is an extension of the MediaStream and WebCodecs APIS, allowing applications to:

  • Access raw data in MediaStreamTrack;
  • Define new custom MediaStreamTracks.

These two functions can be combined, for example, to create media effects (e.g., “funny Hats “).

The API relies on WebCodecs Raw Media interfaces and WHATWG Streams APIS. This feature is part of the WebCodecs source trial.

GetCurrentBrowsingContextMedia source trial version

This is a new experimental API for retrieving current Tab content that is currently under development. Implementation can be used as a trial version for the first time, for more information, see: docs.google.com/document/d/…
