[Live-devel] Audio Sync Issue from Axis Camera

[Justin Miller]

We are trying to use an Axis Q6034 Camera that sends out a video and audio
stream in h.264 and acc. The problem we are having is that the audio and
video do not sync no  matter what we try. We have tried the -y hook and
that actually causes a drift in the audio after a period of time. We have
tried changing the bit rate and GOV settings, I have been able to get the
closest results by setting the camera to 24fps and the software to 23.95
but we get inconsistent results. Typically the audio is ahead of the video
by 2 to 6 frames. Also this is not a  bandwidth issue as we have tested
that, there is also no packet loss and the time clock on the camera matches
the machine, as it syncs to the machine. Any suggestions?


Thanks,
