Grab video (994×746) with 30 pixel top-offset.

ffmpeg -r 24 -f x11grab -s 994x746 -i :0.0+0,30 -threads 0 -vcodec libx264 /tmp/out.mkv

The 994×746 video size matches the minimum window size of Ardour, and the 30 pixel verticla offste matches my toolbar at the top of the screen. In other words, this command records the entire Ardour window when positioned in the upper left corner of my screen and sized to the minimal size allowed by Ardour.


jack_rec -f /tmp/showcase.wav 'ardour:master/audio_out 1' 'ardour:master/audio_out 2' -b 16 -d100000

NOTE: Without the -d option it seems the recording is terminated immediately…
NOTE: Ardour and jackd must be started before this command is activated.


Transcode said video to ogg format (html5 video tag compatible):

ffmpeg2theora /tmp/out.mkv
