Trouble playing video with dvdsub

[RonZwanson]

I did a bit more troubleshooting and it seems I was wrong, it's not the dvdsub that causes the issue, it's the AAC 7.1 audio track that cause the transcoding to fail somehow, on my phone i was able to play the movie by selecting a secondary audio track (AAC stereo) with the dvdsub enabled, it transcoded without issues.
