Jellyfin Media Player video lags and stutters on raspberry pi 4

[Kenji Bailly]

I installed the media player using flatpack, but I'm unable to watch anything since the video playback is so slow and it stutters like crazy on my raspberry pi 4.

The server is installed on my Linux server, which is a different and more powerful device. 
I just want to play the content on my raspberry pi.

I'm wondering what I can do to make it work.

Long story short, RPis have terrible codecs support, hardware accelerated anything barely works, and they just aren't great for watching or serving media.

Watching jellyfin videos from the chromium browser on my rpi4 works perfectly though. So are you sure the problem is the rpi4 when using the jellyfin client app?

Without knowing the resolution and codecs of the videos you watch vs what OP was trying to watch, its hard to compare your experience with theirs.

Good point XD
Not sure what OP is trying to watch, for myself 720p and 1080p work perfectly as long as it's x264. If it's x265 then the server needs to re-encode.. which is annoying hence why it would be nice to have the Jellyfin Media Player app on RPi4 that would play x265 directly (If it's even possible, but librelec apparently can do it without issue)
