Thanks a lot Dan. I used this command line: arecord -D default -t raw -c 1 -f S16_LE -r 48000 - | \ ffmpeg -f s16le -ab 128k -ar 48000 -ac 1 -i - -acodec mp2 \ -f x11grab -r 2 -s 1400x1050 -i :0.0 -vcodec mpeg4 \ /home/jmpoure/kdenlive/capture.avi But I only hear scratches. Image is good. Any input? Kind regards, Jean-Michel
