H.264 and H.265 unwatchable in browser and Jellyfin Media Player on my Mac

[dekomoon]

Color is still an issue when I play videos on my browser, but I have come to accept it as something MacOS related where browsers can't play 10-bit videos properly sadly. Then again, I have no plans to watch it in the browser as H264 at 35mbps for 4k60 is pretty bad haha.

Code:

PlayMethod=Transcode, TranscodeReason=DirectPlayError )

It looks like it tried to direct play, but had to transcode for some reason.  It's not clear from the server logs why there was a direct play error.  Client side bug?

The reason why is because I forced AV1 transcode on the client side plus specified in client setting that I prefer transcode to H265. When I do not force transcode AV1 videos, I only get the following log:

Code:

However the playback still lags and stutters sadly.

Can you tell us a bit about your server? Your client is on a Mac, but your server appears to be linux with a Nvidia GPU? What are the full specs of your server?

Yes gladly! My host/server is running Ubuntu 22.04. Jellyfin is running as a container of the latest official Jellyfin's image. My Docker version is 24.0.4 of build 3713ee1. I passed my GPU to my docker container. Here is my compose file: https://pastebin.com/g82fNhqF

The ffmpeg logs indicate that transcoding is happening fast enough, but I wonder if it is struggling to transcode AND serve the transcoded files.

Yes it seems to be transcoding above 60fps. Bitrate is only 35mbps (my apologies on my last reply on my mistake on kbps) so I do not think my network is the problem. Both my host and client is connected to Ethernet with a upload and download speed of 300mbps.
