Still broken after 92053aa26053b941a027a4fc56674d7d86ba1e5 that fixed #6850. It is now even worse, seeking forward does not work.

The ts patch was applied and seeking by bytes was disallowed that thus fully fixed your ts link. Now we need to apply fmp4 patch, please rework it if needed and resend.

It is now even worse, seeking forward does not work.

This indeed broke latest fmp4 stream of apple. Need to fix ASAP by applying fmp4 patches above.

It ALSO APPEARS to cause a DOS and horrible crash of terminal app on windows. Older version of fmpeg works good enough.

Can you look into it? This is IMHO critical status, seeking in fmp4 is completly broken after 92053aa26053b941a027a4fc56674d7d86ba1e58 which was needed to fix fragmented ts.

Any Update onto this issue? I basically thought for months that this issue was related to VideoJS as ts segments were working fine! The problem is that HEVC/AV1 and/or 4k HDR content does not work properly with .ts segments. Basically blocking any new format to be streamed as long as this issue isn't solved! Urgently requesting a fix.

Thanks in advance
