-----------
Implement MediaStreamTrack transfer to dedicated workers in same agent cluster
rdar://121180907
https://bugs.webkit.org/show_bug.cgi?id=267682
Reviewed by Eric Carlson.
Introduce MediaStreamTrackDataHolder which is used to store the
MediaStreamTrack information necessary as part of the transfer.
It keeps the track source alive and allows to create a MediaStreamTrackPrivate
from it.
We expose MediaStreamTrack to window and dedicated worker but only support
transferring tracks in the same agent cluster.
The goal is typically to transfer the track from a window context to a
dedicated worker created by the window context, to do track video frame
processing.
Given the source, even if transferred, is kept by the document for which was
created the source, there is no impact on the privacy indicators.
The new tests highlighted three issues in MediaStreamTrackProcessor:
- The observer needs to be created right away or we need to add an if check. We
are creating it right away
- We were missing protecting the processor in
MediaStreamTrackProcessor::VideoFrameObserver::videoFrameAvailable.
- We should call ReadableStreamSource::pullFinished() only if enqueuing went
well.
