The way I would do it (a variant on this may suit you) is: 1. ‘rip’ the audio from the original video into a lossless format (such as WAV) using avconv; 2. overlay/mix the additional audio using a tool such as Audacity (GUI) or sox <http://sox.sourceforge.net/> (command-line); 3. make a new video file by replacing the audio track on the original with your mix using avconv. -- *Cheers — Leon*
