Yes really, the only way I have been able to get a picture using mplayer
with my v4l capture/tuner is to set the outfmt to uyvy
Even with this the colors are all wrong, its like a very green phto
negative. I have tried all combinations of the outfmt and -vc options, the
only picture I get is when using uyvy
All other v4l apps (xawtv, zapping etc) work well, as does mplayer with
everything other than the tv
The video source is a LD player with a PAL disk, I have tried other video
sources and that makes no difference.
My hardware/software is
Dell Dual Xeon, 1GB RAM, Haupaugge WinTVgo card, hardware RAID 5 (140GB).
running RH7.1 with X4.10 (built from source), 2.4.17 kernel
the command line I am using is
mplayer -tv on:driver=v4l:input=1:norm=pal:width=640:height=480:outfmt=uyvy -vo xv
the output I get is :-
