Video playback in slow-mo - MrFabou - 2024-03-19
I'm using Jellyfin 10.8.13 as a Linux Container in Proxmox with a i5 7500t and it's iGPU.
It work's fine with 1080p content, but if I try to watch HEVC 4K Movies, it only works on my native 4K TV and PC with Google Chrome, not on a 1080p Display with a Google Chromecast 4K.
If I change the bandwidth to 3-5mb/s it works fine. With set to "automatic" the video playback is in slow-mo and the audio is playing on 100%
I checked the logs and got a warning:
Code:

Did you manually set the player to libVLC? If so, try setting it to exoplayer. I've had a much more consistent experience setting it to exoplayer on my CCwGTV 4K.

It is already set to "ExoPlayer"
RE: Video playback in slow-mo - TheDreadPirate - 2024-03-19
Is it slow-mo only when it is direct playing? When you played it on your 4K TV and PC was it transcoding for those devices? I'm assuming this 4K TV is also running Android TV? Is the ffmpeg log you included from when you were playing on the CCwGTV with the bit rate set to auto or at 3-5Mbps?

What does direct playing mean? I just press play
Render/3D is not used when I play it on my pc, so I don't think so!
My 4K TV is running Android TV
The log is from the quality set to "auto"
RE: Video playback in slow-mo - TheDreadPirate - 2024-03-19
Direct play = no transcoding.

Thanks!
No, without transcoding (on my 4k tv and pc) it's not in slow-mo.

Weeeeird. Is your Chromecast running Jellyfin 0.16.6? Is the OS fully up to date? What happens when the libVLC player is selected?
In the Jellyfin web UI, can you copy and paste the "media info" menu for this video?

I'm running 0.16.7, OS is up-to-date
With libVLC I'm getting a still image, maybe if I wait 10 min the next image is moving in like a diashow :'D, but no audio, still image

Does it only happen with this particular 4K HDR movie? Or all 4K HDR movies?
