system-audio delay sync #867

Open PeterAkakpo opened 6 years ago

PeterAkakpo commented 6 years ago

playing a video file with VLC plays okay, but with caparcg 2.2 latest download, audio and video are out of sync. the audio lags behind. this happens with any video file. I have also changed the video mode setting to match that of the file but it didn't have any effect. attached is the diagnostic screen ccg diagnostics ccg diagnostics1

the above images are for 1080p2500, which is not the file format

below images are for the 720p2398 , the format of the file

System audio is unfortunately not ready for production. This is a known issue. We will need to add configurable delays in consumer configuration so that one can correct for this.

Robert, is the delay/offset predictable and stable?

ronag commented 6 years ago

@jesperstarkar yes, it should be, but we will still need sample compensation for system audio for 100% correctness.
