Comment (by JEEB):

 To debug what the actual FFmpeg libraries return from the MPEG-TS input,
 you can try the following:

 {{{
 ffprobe -v verbose -of json -show_programs -show_packets file.ts >
 packets_and_programs.json
 }}}

 You can then parse this with python or so, to get the packet information
 on the subtitle packets.

 For the durations, it seems like ffmpeg.c doesn't handle the duration that
 we utilize for "show until next packet" things. "-fix_sub_duration" should
 improve this.
