[MPlayer-users] Trying to view TV from an s-video input

[Mark Zimmerman]

Greetings:

I have connected the s-video output of my Dish receiver to the s-video
input of my pcHDTV HD-3000 card and I am trying to view the results on
my PC. I can get a picture but I cannot seem to find the right color
space. The best I can get is a psychedelic looking red and green
picture - but it is the right size and shape. It is like looking at a
color film negative. I have tried all of the outfmt= options but none
are any good. From what I have been able to find out, s-video uses a
YC color space.

Some of the things in the console output indicate that support for
this may not all be there, but I would appreciate any ideas.

Here is a sample execution:

qpc$ mplayer -tv
driver=v4l2:device=/dev/video1:input=2:noaudio:outfmt=rgb24 -vo xv
tv://
