Transcoding when it shouldn't be #669

Describe the bug

I'm running the latest version of the Jellyfin server (10.8.8) and the current release of Swiftfin on an Apple TV 4K. I go to playback various 4K files from my server, and the Server claims it's doing direct play but when I look at top and CPU usage the server is actually maxed out and doing ffmpeg transcoding it appears.

Application version

1.0.0

Where did you install the app from?

Device information

I've experienced this, as well. Infuse is able to play the same file without transcoding.

What is the bitrate of these 4K movies?

iammattcoleman commented 1 year ago

I experienced it with a 16mbps 1080p 8bpp SDR H.264 file, not 4K. (In case it's relevant, it has 5.1ch DTS-MA audio.)
