Transcoding issues and hardware acceleration

[TheDreadPirate]

The third digit is a minor version. Bug fixes and security patches only, usually. Each 10.# version is a fairly major version change for Jellyfin with new features, API changes, and dependency upgrades. For example, going from 10.9 to 10.10 comes with a major ffmpeg upgrade from 6.1 to 7.0.2. There were 4 additional 10.9.X releases (10.9.11) and we are up to 10.10.6.

But the log you shared doesn't appear to match your screenshot. In your screenshot you checked HEVC 10-bit decoding (you should also have HEVC checked) but the ffmpeg log doesn't indicate that it is hardware decoding this video. Nor does it show you have tone mapping checked (NOT VPP tone mapping).
