[MPlayer-users] No image with tv unless outfmt=uyvy

[Per Mellander]

Hi!

I'm using a similar setup ( WinTV Teather, AMD 1.2GHz 512MB RAM etc. )
and
was also having problem with -tv option. ( Funny colors. ) I use the -vo
mga
and at last I got it working. I patched the tv.c source that had YUY2
outfmt
commented out and put it back in. It's the only format that I know of
that
Hauppauge cards support. So running:

mplayer -tv
on:driver=v4l:input=1:norm=pal:width=640:height=480:outfmt=yuy2 -vo mga

made my day :)
