We have interest in being able to read timestamps in protocol headers also.

Do we have a doc that specifies which protocols in the video stream ffmpeg
supports with a timecode, and what format of the timecode is?

Does anyone have experience which layer  within the network stack has a
timestamp that is accessible, available and reliable?
