Hi
I'm trying to capture a screencast of a jack2 client (renoise), but it
seems recordmydesktop and jack2 doesn't work well together. Anything I
should do different? Any alternative to recordmydesktop that I should
try instead?
I'm running ubuntu 12.10...

Hi,
I've had some success using Kazam on Ubuntu 12.04. It's possible to
get the audio into it using the Jack -> PulseAudio routing, which
might be on by default or by ticking the dbus option in QJackCtl?!
Though I'd recommend using the suggestion of recording the audio
separately. It sounds fine when recording, but sometimes the audio in
the recorded video can break up a bit.
Best wishes,
Neil

For me screen-capturing with jack seems terribly broken at the moment...
jack capture with (gtk)-recordmydesktop is broken since at least 1 year,
and seems related to the funky width and height values reported when you
use it with jack.
I had an ffmpeg (and newer avconv) script which worked very well until a
few months ago which is now also broken on my system (debian wheezy):
ffmpeg -f jack -ac 2 -i ffmpeg -f x11grab -r 30 -s 1280x800 -i :0.0
-acodec pcm_s16le -vcodec libx264 -preset ultrafast -threads 0 output.avi
Adapded from some blog online I can't recall. Actually it seems the X11
grabbing part is broken there, as recording a wav file through jack works.
I had tried gstreamer, but couldn't really get it to work (audio was
stuttery).

Do you actually need Jack for what is going on in the video? Could you not record using
Renoise in ALSA mode? Obviously you would lose come capability, such as external plugs and
routing, but depending on exactly what you wish to record it might be an idea.
