which of course involves compiling ffmpeg with jack enabled (and
recording is a bit clumsy as you have to manually connect the jack
client to ffmpeg jack client then cut that boring part from the video

I was wondering what people's setup for (especially on debian) are, and
if any simple solution currently exists.

Hi Lorenzo,

Maybe this Wiki page could be helpful:

Thanks Jeremy! Interesting approach... The Xephyr part is neat:
Although on debian you need to compile ffmpeg for x264 support, so maybe one might as well compile it with jack?

Here's my one-liner for ffmpeg.

ffmpeg -f jack -ac 2 -i ffmpeg -f x11grab -r 30 -s 1280x800 -i :0.0 -acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads 0 output.avi

Lorenzo

Best,

Jeremy
