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

[Andre Bruce]

I have a duron 950mhz, 512 ram and had the same problem.
The problem is that my CPU (maybe yours too) is not fast enough to
compress in realtime. My solution was NOT to encode audio.
Change your -aoc mp3lame to -oac copy (or pcm) and you wont get video
buffer full anymore(i didnt.. )
The file will be bigger because sound wont be compressed.
Then just run mencoder and re-encode sound:
mencoder  -oac mp3lame -ovc copy input_file.avi -o output_file.avi
That way i can record everything running kde, and even run some
programs!! (if i run lot o f things, i get video buffer full :P )

What i usually do is: i have 1 script for recording, and after recording
it automatcly re-encodes! You should do something like that!
