[MPlayer-users] Problems recording pwc webcam

[andrea]

Hi,

I am trying to record using a Logitech PWC webcam (Logitech QuickCam Pro 4000).
I can play using mplayer but recording fails

1) mencoder fails to start
2) I cannot use -dumpstream in mplayer

Case 1) is the one I would like to fix.
Do I need to tell more about the format to mencoder?
mplayer does not need anything else to play it.

I report below the output I get

1) mencoder -v -tv driver=v4l2 tv:// -o abc.avi
