Ok, somebody please tell me I'm not crazy:
I've been experiencing problems with audio/video synchronization when
capturing MJPEG avi files using xawtv. I tested on three different
systems, with three different sound cards, and two sets of sound
drivers, but the results are always the same - when capturing long video
sequences, upwards of an hour, I see the video diverging from the audio
by anything from a second or two to around five seconds.
Now, I don't like whining when I can instead read the source. It turns
out that xawtv's capture code is trying hard to sync the video to the
system's real time clock. I hacked it so it now synchs to the audio time
line, and I no longer lose sync, even after capturing video for over an
hour. Except for some minor issues, that's good enough for me.
I asked Gerd about it, and as far as I can see, he is in the opinion
that I'm wrong, his code is doing the right thing, and that my sound
card is a piece of crap. Actually, the sound card IS a piece of crap,
and I said it, not Gerd. He merely agrees with me on that.
So, am I the only one who's having problems with xawtv's capture code,
am I imagining things, or what?
Thanks in advance for the diagnosis,
Ori Pessach
