Hi, I've the same symptom on oneiric vlc version 1.1.12 streaming microsoft live webcam:

vlc -I dummy --color 'v4l2:///dev/video0:width=640:height=360' :input-slave=alsa://hw:1,0 --sout='#transcode{acodec=aac,vcodec=h264,audio-sync,width=640,height=360}:rtp{dst=0.0.0.0,sdp=rtsp://0.0.0.0:2323/test.sdp}' -vvvvv --sout-transcode-threads 3 --sout-x264-bframes 0 --no-sout-x264-cabac

The problem is that video is delayed (sound is before video). I've tried audio-sync and without but it has no effect.

Using gstreamer on the same system results in perfect sync even after many hours. I've also tried vlc forum to discuss it there: http://forum.videolan.org/viewtopic.php?f=13&t=95866 and the developer says that the v4l2 drivers are broken in some way.
