[MPlayer-users] vide4linux audio and colors

[domi]

Hi!

I could hardly beleive my eyes, when i noticed, that mplayer is - well,
sort of - already capable of using a video4linux device to show tv stuff,
and with mencoder, recording from tv is/should be possible too. I can see
the future, mplayer making coffee, washing clothes for me and who knows
what else :)

I tried it, and managed to view tv, but there was no audio! And somehow
colors were not right, people had blueish skin, and everything else was
different in color then normally. Is that just because of this part of the
code is in a very early development state, or am i doing something wrong?
When recording, of course the same thing happened, recorded video got
strange colors, and no audio.

I put here some outputs, maybe it helps:

mplayer -tv
