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.
