 Summary of the bug:

 This commit
 http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=17e4746687abc53f0a042620a7af6dd6cea44b80
 broke hardcoding of subtitles when encoding with libx265.

 Verified it is still broken with the latest Gyan build 2025-05-15-git-
 12b853530a

 How to reproduce:
 {{{
 % ffmpeg -i input -filter_complex [0:v][0:s:0]overlay -maxrate 89000k -crf
 16 -c:a copy -c:v libx265 -preset superfast -f mpegts file.ts
 ffmpeg version 2025-05-15-git-12b853530a
 built on 2025-05-15
 }}}

 I also have an automated test on GitHub for periodically checking whether
 this is fixed.
 You can see the failing build when FFmpeg is updated to latest:
 https://github.com/UniversalMediaServer/UniversalMediaServer/pull/5537/commits/bdcca6b4f2e06784a3de2f6cb3bd39ab47a69c08

 And the succeeding build when the older 7.1 release is used:
 https://github.com/UniversalMediaServer/UniversalMediaServer/pull/5537/commits/7065d765dac8acdc57d13a5628d15b891b3b1fdf
