 Summary of the bug:

 I have muxed a bluray into a mkv using ffmpeg.
 But now ffmpeg is unable to work with that mkv because of the included pgs
 subtitle.

 (Subtitles are working, checked it with mpv).

 ffmpeg error:
 {{{
 [matroska @ 0x1f4af20] Application provided invalid, non monotonically
 increasing dts to muxer in stream 4: 14875 >= 14874
 av_interleaved_write_frame(): Invalid argument
 }}}

 ffprobe gives:
 {{{
 [matroska,webm @ 0x1e60cc0] Could not find codec parameters for stream 4
 (Subtitle: hdmv_pgs_subtitle): unspecified size
 Consider increasing the value for the 'analyzeduration' and 'probesize'
 options
 }}}


 How to reproduce:
 (even -fix_sub_duration does not help)
