H.265 files cannot be played in Safari without transcoding, even though it supports it.

[Southpaw1496]

Describe The Bug H.265 files cannot be played in Safari without being transcoded, even though it supports them. I have played back the raw files natively in Safari without issue, it only doesn't work when played through Jellyfin (without transcoding).

Steps To Reproduce

1. Obtain an HVEC video, and add it to Jellyfin
2. Disable transcoding for the user you wish to test with (Dashboard -> Users -> User ❌ Allow video playback that requires transcoding).
3. Try playing the H265 video
4. Observe

Expected Behavior Since Safari natively supports H.265 playback on Safari 11 (on macOS High Sierra or later) and later, the video should play successfully without transcoding enabled.

Logs Tested with the short "8 Ball Bunny"

Screenshots

System (please complete the following information):

• Platform: Docker (also tested on Debian Bullseye)
• Browser: Safari 16.2
• Jellyfin Version: 10.8.8

Additional Context I have also tested playback in the desktop app, Chrome, and Firefox. Chrome and the desktop app work fine, and Firefox does not, but it doesn't support H.265 in the first place anyway.

Have you tried enabling the fmp4-hls option in the web client? Screenshot_20221226-155254.jpg

I have now, and there is no difference.

Looks like HEVC is currently disabled on Safari (because some version was lying about support): https://github.com/jellyfin/jellyfin-web/blob/b90936912716832cab6e70b8f2876ac9f2ddf94d/src/scripts/browserDeviceProfile.js#L516-L519

It is better to try to rebuild the web with the discarded condition. But if you can't, you can try to remove s.Z.safari|| in main.jellyfin.bundle.js in the part that looks like: l(n,e)&&(s.Z.safari||L.push("hevc"),...).

Would this fix ever be added to Jellyfin itself, perhaps as a config option? Could you check for a specific version instead of just Safari in general?
