Same problem also with simply:
$ ffmpeg -f alsa -i hw:1,0 -f video4linux2 -i /dev/video0 out.mpg
, and audio completely out of sync...
And complete command output is still missing (it's always helpful)....
Since this works--
mencoder tv:// -tv driver=v4l2:width=640:height=480 [...]
The computer you're using may not have enough resources to process those
large frames. If the native resolution of the devices is 3200x2400, that's
23MB/frame, and encoding often needs to keep a few in memory at once. As you
tried in mencover, dial down the capture size in ffmpeg and see if that work.
