Details

Similar to Bug 1861769, we should add a transfer property to EncodedVideoChunkInit's WebIDL and update its constructor algorithm. This will allow users to transfer ownership of data from a TypedArray to the EncodedVideoChunk, avoiding unnecessary copies. (See Bug 1861769, comment 1 for more details and rationale.)

dictionary EncodedVideoChunkInit {
  ...
  required AllowSharedBufferSource data;
  sequence<ArrayBuffer> transfer = [];
};

The expected outcome is that the implementation should pass the related WPT in transfering.https.any.js.
