I’ve just recorded my first test screencast. I’ll need some more practice before posting on Youtube…
Here’s the command I use under OpenBSD to record:
ffmpeg -f sndio -i rsnd/0 \
-f x11grab -r 10 -s 1284x772 -i :0.0+1,16 \
-acodec pcm_s16le \
-vcodec libx264 -vpre lossless_ultrafast -threads 0 \
-y "./$(date +%FT%T).mkv"
