Re: new option x11grab? (Re: ffmpeg x11grab)

[Victor Dorneanu <victor%dornea.nu@localhost>]

Oh thanks! I'd use some other codec and call ffmpeg like this:

ffmpeg -an -f x11grab -r 25 -s 1024x768 -i ":0.0" -vcodec mpeg4 -sameq
/tmp/bla.mp4

But its up to you when it comes to the desired quality :)
