New description:

 Summary of the bug:

 Attempted to remux MP4 to Matroska. Accidentally set -c:s copy from a TX3G
 track (which cannot fit in Matroska). FFmpeg raises the error to say this
 is not supported, but then hangs and needs to be killed.

 In 6.x, CLI exits properly on error and does not hang.

 How to reproduce:
 {{{
 ffmpeg -i "INPUT.mp4" -map 0:0 -codec:0 copy -map 0:1 -codec:1 copy -f
 matroska "VIDEO.mkv" -map 0:2 -codec:0 copy -metadata:s:0 title=BUG -f
 matroska "SUBS.mks"
 }}}
