 Summary of the bug:
 With some files, even though the video file contains closed caption data
 when played in VLC, the ffmpeg srt extraction produces and empty file.
 This happens with the git version 20240629 and release 5.0.

 However, release 4.3.2 works fine with the same input and produces correct
 output.

 How to reproduce:
 {{{
 % ffmpeg -f lavfi -i movie=fox5-202410230440.ts[out+subcc] z.srt
 ffmpeg version:
 5.0 and git build 20240629 by John van Sickle
 built on ...
 }}}
 Patches should be submitted to the ffmpeg-devel mailing list and not this
 bug tracker.
