v4l: choppy sound (timing screwed, stopping resampling)

[fish]

When i try to view the v4l with vlc like that:

Code: Select all

vlc -vvv --color v4l:/dev/video0:adev=/dev/dsp:audio=0:norm=0:frequency=231250

I get those warnings and the sound is really choppy:

Code: Select all

audio drift is too big (-140977), clearing out, buffer is 69756 in advance, triggering downsampling, timing screwed, stopping resampling

When i leave the /dev/video0 out (so i have no video) the sound works fine:

Code: Select all

vlc -vvv --color v4l::adev=/dev/dsp:audio=0:norm=0:frequency=231250

Maybe some synchronisation issue?

I use vlc-0.8.5-r5 on Gentoo
