[FFmpeg-devel] [RFC] larger PCM packets from avidec

[Reimar Döffinger]

Hello,
with the sample in MPlayer/incoming/demux-avi/mjpg-pcm.avi the AVI demuxer
returns audio packets of 128 bytes size each (in this case, 3ms worth of data),
causing quite a overhead.
It's not a big issue, but it seems too extreme and since there's no comment
on the code how that value was chosen I'd like to hear comments.
I guess the 1024 of patch below would be going too far in the other direction,
it's just meant as an example.
