Oh yeah, you are right.
But it's a copy/paste of one of the trick i've tried, my mistake
Sure i've already done an :
ffmpeg -f jack -ac 2 -i hw:1 -f x11grab -s 1920x1080 -r 25 -i :0.0
nul.mp4
But the same...
Stangely the jack_capture - or audacity - command work great...but i
want to avoid having, 1 sound file, 1 video file and then join them :/
Dont want to bring out the big guns for that.
Still looking....
Thank you anyway for reading.
All the best.

Only Jackd using it - and qjackctl.
Your original email had this as the ffmpeg command:
ffmpeg -f alsa -ac 2 -i hw:1 -f x11grab -s 1920x1080 -r 25 -i :0.0
00screencast.mp4
You are telling ffmpeg to use the ALSA device, but the ALSA device is
in use by jackd.
If you want to have ffmpeg capture the ALSA device then don't start
jackd. If you want to have ffmpeg use jackd ports then read the
ffmpeg man page for the correct options. The "-f" argument would be
jack instead of alsa, but you have to look at all the details of how
to get the ports connected correctly. I think you need to use
qjackctl or jack_connect to connect the ports after starting ffmpeg.
