gorecord foo.mp4
I've tried all of the screen recorders available for Linux and this is easily the best. xvidcap segfaults; VNC is too much hassle. There are alternatives of this command already here that I am just too lazy to reply to. Messing with the frames per second option, -r, 25 seems to be the best. Any lower and the video will look like a flipbook, if it records at all - -r 10 won't - any faster is the same, oddly enough.
Edit: CLF doesn't like my long command to add audio, so here it is in the description.
goaddaudio()
{
if [ $# != 3 ]; then
echo 'goaddaudio < audio > < src video > < dst video >'
return
fi
f=goaddaudio$RANDOM
ffmpeg -i "$2" &> $f
d=$( grep Duration $f | awk '{print $2}' | tr -d ',' ) &&
rm $f &&
ffmpeg -i "$1" -i "$2" -r 25 -ab 192k -ar 44100 -sameq -t $d "$3"
}
There are 7 alternatives - vote for the best!
