Comment (by CoRoNe):
I only saw your posts just now, because I didn't get email-notification.

which files are supposed to be submitted to Patchwork).''
Last time I didn't actually apply your patch the official way. I just
manually edited movtextenc.c. I've also done this now, because of line-
numbers in your patch not being up-to-date anymore.

Everything is just plain text. The subtitles vanish randomly.
I've successfully compiled FFMpeg with your changes, but after creating
another test-video (//'VPWON_1269922(FFMpeg-mux_t32)patch.mp4'//) my TV
didn't display subtitles at all anymore.
No problem with MPC-HC on my pc.
commandline used:
{{{
ffmpeg.exe -i "full-episode" -i "VPWON_1269922.srt" -t 32 -c copy -c:s
mov_text
-metadata:s:s language=dut "VPWON_1269922(FFMpeg-mux_t32)patch.mp4"
}}}
