The first number x represents the number of the input file. Note on the enumartion ‘#x:y’: Counting starts with 0.

If I flipped which map comes second, that is the stream that is audible in the output. I have used the following but again its seems to ignore the first -map option.

Basically I recorded game footage and the original file had both the in game sounds as well as the mic recording commentary on top. ffmpeg -i 'The Bunker.avi' -vcodec h264 TheBunkerMix.mp4īut, the resultant file only had one track/source. I have successfully converted the video without loss of quality with the following. When I pop the file into avimux, I can clearly see two audio tracks/sources. The video is using dxtory video codec and unknown audio codec.
