 > Can you try this patch series:

 > and see if it fixes things for you in the following situations:
 > * playback with ffplay;
 > * transcoding to a different sub codec (dvdsub; {{{-fix_sub_duration}}}
 is required, and {{{-s:s 1920x1080}}} also if the subtitles arrive too
 > * hardcoding the subtitles on the video.
 All three situations are fixed with your patchset (attached), both for the
 sample here in this ticket, and the sample from ticket #598 (that needs
 the CRC-check in pat_cb() disabled)!
