[MPlayer-users] TV capture problems

Wed Jan 9 18:12:01 CET 2002

Hi,
I'm having 2 problems, and I have a question,
is there a way to when encoding use deinterlace
filter(a diferent one from divx4) 

Thanx 

1. When I try to watch TV with mplayer it says no
sound, as you can see I can change channels, and
besides I hear the TV sound that, my tv card works
well with xawtv.

2. The real problem is that I want to capture some
video, when I try to capture some video it works OK,
but then I try to play the avi and the avi goes too
fast time passes faster, althou the time is the same
as when I capture the file, I think is a problem that
mencoder can't capture the audio of my TV card, when
this happens the avi doesn't know how to count time or
something like that...here:

mencoder -tv
on:driver=v4l:width=640:height=480:fps=30:outfmt=i420
-vc rawi420 -ofps 24 -ovc divx4 -divx4opts
