MAKE SURE TO START VLC
THEN START THE AUDIO SOURCE … OR IT WILL SAY : VLC can’t recognize the input’s format:
The format of ‘file:///tmp/nowardev.mp4’ cannot be detected. Have a look at the log for details

cd /tmp ; cvlc --jack-input-auto-connect screen:// --screen-fps=25 --input-slave pulse://jack_in --sout "#transcode{venc=x264,quality:100,scale=1,fps=30,acodec=mp3,ab=128,channels=2, samplerate=44100}:duplicate{dst=std{access=file,mux=mp4,dst=nowardev.mp4}}}"

multiple input slave with vlc

cd /tmp ; cvlc --jack-input-auto-connect screen:// --screen-fps=25 --input-slave pulse://jack_in#pulse://alsa_input.usb-046d_081b_2F2432A0-02-U0x46d0x81b.analog-mono --sout "#transcode{venc=x264,quality:100,scale=1,fps=30,acodec=mp3,ab=128,channels=2, samplerate=44100}:duplicate{dst=std{access=file,mux=mp4,dst=FILE_GRAB_DESKTOP_AUDIO_JACK.mp4}}}"
