[MPlayer-users] mencoder TV Capture - video buffer full

[David Frey]

I am trying to record from my Phoebe TV Master in Canada using
mencoder.  My computer is an Athlon XP2400+ with 512 MB of RAM and
plenty of free HD space.  I looked through the man page for mencoder and
googled a bit.  I came up with the following command to record 30
seconds.  I am trying to use the onboard audio capture rather than the
line in so that's why I am using dsp1.

mencoder -tv
on:driver=v4l:width=640:height=480:fps=29.97:norm=NTSC:chanlist=us-cable:channel=8:adevice=/dev/dsp1 -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=1460:keyint=300 -oac mp3lame -lameopts cbr:br=128 -endpos 30 -vop pp=lb,pp=tn:3 -info name="test" -o test.avi

After I run the command, I can see my memory usage rising quickly in
gkrellm.  Once the memory is almost all used up, this error is printed
over and over quite quickly "video buffer full - dropping frame".  I
have included the full output (minus the repeating error at the end)
below.  I can view the TV using both mplayer and xawtv.  Another issue
is that once I try to start recording, the audio is played through my
speakers for some reason and then after I terminate the recording, the
sound won't stop until I unload the bttv module.  Any ideas?
