I am happy with everything that is able to record mpeg2/mp2 (or even
A few days ago someone suggested that mencoder would be able to use the
mpeg2 support of recent ffmpeg cvs versions. The public cvs server of
ffmpeg lags a few days though, so I can't yet try that.
So I decided to test it with mpeg1 in the meantime. This works, but I
can't get any sound! The only legal combination is to use pcm audio
"codec" and even that does not work. Mencoder says it's recording audio
and video, but the resulting stream (!) (an avi is useless for me!)
lacks any audio.
So I suggested that it might be possible to add support also for audio
codecs from the ffmpeg/libavcodec package but nobody seems to be
interested. Support for ffmpeg/libavformat would be really great.
Maybe it would even be an option to drop all encoding and format stuff
from mencoder and make it a grabbing front-end to ffmpeg. Which imho is
great, handles a lot of codecs and formats, but doesn't handle a/v sync
