Bug Description

Encoding dual-audio video files might result in only the first track remaining in the resultant file.

Confirmed. LosslessCut shows that after the file is encoded, it is missing the second track.

Potential fix: forcing ffmpeg to use all tracks when encoding files

Possible solution:

Based off this post, you can probably do:

ffmpeg -i in.mp4 -map 0 out.mp4

Possible issue:

It may be better to have an option to merge the audio streams as opposed to keeping both separate, as video players will only play the first stream by default.

Now split into a separate issue as #12.
