Dear List,
I have a Sonix USB 2.0 webcam that is using
V4L2. There seems to be a problem with
mplayer..
I did..
svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer
(there is an earlier posting to this mailing list
that says that the repository version should work
OK with V4L2).
Then complied (configure, gmake, gmake install) and
tried
--------------
linux-q5nk:/home/sampsa/mplayer # ./mencoder tv:// -v -tv
driver=v4l2:width=576:height=576:input=1:device=/dev/video0:immediatemode=0:forceaudio:outfmt=yv12
-o outfile.avi -lavcopts vcodec=mjpeg
-----------
It gave me the following output..
