Summary: Sound problem due to not enough dropped frames(?)
Initial Comment:
Hi,
I have the following problem using newer version of
avifile (currently I'm using debian/latest sid
package):
I use a pretty slow computer K6/2-500 + G200 and
hence I have some dropped frames using DIVX-Playback.
Yet what is annoying that it seems that not enough
video frames are dropped to ensure proper playback of
the audio stream.
When playing back the audio stream alone or when
partially covering the video with another window, the
sound plays perfectly (the computer seems to be able
to keep the audio queue(?) filled).
Yet when I play back audio and video together and
make the computer do the work for the whole picture,
it works for a few seconds (audio queue filled
initially?) and then the audio quality is getting
very poor with static clicks and unclean noises ...
Previously I used an ancient version of avifile which
dropped far more frames but which played the stream
flawlessly.
Hence my guess is that the audio queue somehow
underflows. Note that even when the audio quality is
poor, I do not necessarily have dropped frames.
Best regards,
Ralf
P.S. I use OSS/Alsa audio playback and tried both
MP3-decoders with the exact same result.

Okay, I played just a little bit around and it seems like
SDL audio playback is working perfectly.
Hence it seems to be an OSS (OssAudioRenderer?) problem
only.
