Hi,
This is a repeat request, as it's kind of a critical question for me.
Please help!!
I've got audio data coming into the output buffer of my CoreAudio
driver from Final Cut,
and at the same time there is video coming through Quicktime.
So I'm trying to sync the audio/video when playback starts.
My question is: do I assume that audio starts at the beginning of my
output buffer (at sample 0),
even if the actual audio data begins somewhere else (around sample 1100
typically)?
Or do I look for where the HAL starts writing data, and mark the start
of my first audio frame there?
So that I'm in sync with the first video frame.
Thanks,
Tommy Schell
