Not working for me and this is getting me insane!!!
First of all, I had to adapt that command since it simply didn't work.
ffmpeg didn't knew what "alsa" was :s
> Unknown input or output format: alsa
I'm using ffmpeg SVN-r19468 built on Jul 20 2009 20:26:33, gcc: 4.3.3
I tried the following but only got a black screen and no sound:
Note that I'm trying to capture output audio.ffmpeg -f oss -i /dev/audio -f x11grab -s 1280x1024 -r 24 -b 100k -bf 2 -g 300 -i :0.0 -ar 22050 -ab 128k -acodec libmp3lame -vcodec libxvid -aspect 1.6 -sameq MyScreencast.avi
That is, I want to open a video file and capture what is played to the speakers.
Ideally I would like to record both output and input audio streams.
I have nVidia proprietary drivers.
Any ideas?$ aplay -l
