Re: how to use mencoder to record TV program

The command you gives does not work.
It seems to me that you miss "-tv", so I add it, mencoder says sth. wrong with audio device.
I think I can omit chanlist and channel specification in mencoder command, because I can use the command below to watch TV:

mplayer -tv driver=v4l:width=640:height=480:outfmt=i420 -vo xv tv://

Maybe mplayer can manage to do its job with defaults. Omitting them will make things a little easier for me. I'm in China, which use china-bcast in xawtv.

I try a command in page below, it seems to have similiar problem:


Below is output of your command after adding "-tv":

 As the V4L1 compatibility layer is broken, this may not work.
 If you encounter any problems, use driver=v4l2 instead.
 Bugreports on driver=v4l with v4l2 drivers will be ignored.

Requested mode was stereo, but v4l still reports mono.
You may need "forcechan" option to force stereo/mono audio recording.
