Summary Stop using CMSampleBuffer in MediaRecorderPrivateWriter

Reported 2024-12-14 17:13:30 PST
In preparation of moving the MediaRecorderPrivateWriter in the GPU process so that we can use the AVAssetWriter (which the web process sandbox prevents from running); we need to move data types that can be serialised over IPC. CMSampleBuffer and CMFormatDescription can't be serialised, they are too complex and obfuscated. We should be using MediaSamplesBlock and TrackInfo objects which are platform-agnostic and "easily" serialisable.
