I have a video file and an audio file (that contains 2 channels) and i want to map the video to stream 0 of the resulting file and the audio file to the next stream/s.
Since the audio file has 2 channels, would i have to map it to 2 separate streams? (1 and 2 of the resulting file) Or just one stream?
Finally, how should i go about doing that? I've only tried mapping with video files so i'm not sure how to do it with audio ones.
