Noticed that some files that have embedded subtitle in stream position 1 (normal is: stream 0: video; stream 1: audio, stream 3: subtitle), produce errors when transcoding it.
I don't know which tool produced such files, but quick fix is to remove subtitle, then output file is generated correctly, albeit, without subtitle. Subtitle then could be added in convert tab.
Of course, this could be done by mapping stream numbers, but that can be done by manually editing ffmpeg command.
My solution is quick and easy fix that is not ideal, but works.
