Hello,

We would like to capture the audio signal from another source then video signal. Video comes from X11 and audio from Line-In. In older ffmpeg releases the option "-ad" (set audio device) could be set in the command line. The "-ad" option is no more recognized in the newest release.

How can I set the audio input source in newer Versions of ffmpeg?

Thanks and kind regards
