[MPlayer-users] Re: TV Problem

Sat Apr 27 16:10:01 CEST 2002

Hi again,

I thought maybe a log a mplayer's output would be useful in understanding the
problem. So here it is. (The explanation of the problem is copied at the bottom
of the message) One more precision: I tried accidentally to do this while xawtv
was running (and thus locking /dev/video), and it didn't change anything (no
message like "couldn't open device" ...) !

Command line:
mplayer -tv on:driver=v4l

And there, the black window doesn't react, and the CPU is a 99,... % ...

Thanks in advance for your help!
