PGS and Vobsub burn-in fails with hw transcode, FreeBSD 12.1

Thank you for being willing to take a look! I think the full logs have my token in them, I’ll PM you a link to a cloud share.

Since this is working in your environment, maybe we can figure out what’s different.

And yes, the only common thread is VOBSUB or PGS subtitles. Tested with MPEG2VIDEO and H.264 codecs, 480i, 480p and 1080p resolutions.

For the debug, these are the videos I tested and the rough start and stop times.

Test to show hw transcode works at all

VC1 Transcode test, start ~12:03PM EDT

Each video ~5 minutes wait, then killed when it didn’t start

Das Boot, start ~12:08PM EDT, stop ~12:13PM EDT:
480i (MPEG2VIDEO), VOBSUB

Spirited Away, start ~12:13PM EDT, stop ~12:21PM EDT:
480p (MPEG2VIDEO), VOBSUB

House of Flying Daggers, start ~12:21PM EDT, stop ~12:28PM EDT:
1080p (MPEG2VIDEO), PGS

War of the Arrows OpenSubtitles, start ~12:28PM EDT: Plays fine
Changed to PGS around 12:29PM EDT, error: “Conversion failed. The transcoder failed to start up”
1080p (H.264), PGS
