This change adds support for emitting encoded frames for recording when the decoder can't easily read out encoded width and height as is the case for AV1 streams, in which case the information is buried in OBUs. Downstream project relies on resolution information being present for key frames. With the change, VideoReceiveStream2 infers the resolution from decoded frames, and supplies it in the RecordableEncodedFrames.
