Four considerations:

• Please do not open bug reports to ask questions. Use the Discussions feature instead.
• Please make sure the issue only pertains to Jellyfin Media Player. If it also occurs in the web client, send the issue to jellyfin-web instead.
• Please make sure that your issue is not being caused by errors in custom CSS or note that you are using custom CSS.
  • Notably, there have been instances of custom CSS breaking TV mode.
  • You can disable custom CSS under Display in the user settings.
• Please provide logs. You can drag the log file into the issue to attach it.
  • Windows: %LOCALAPPDATA%\JellyfinMediaPlayer\logs
  • Linux: ~/.local/share/jellyfinmediaplayer/logs/
  • Linux (Flatpak): ~/.var/app/com.github.iwalton3.jellyfin-media-player/data/jellyfinmediaplayer/logs/
  • macOS: ~/Library/Logs/Jellyfin Media Player/

Describe the bug I'm not exactly sure why, but a very specific video seems to lag on desktop client and on my android client, but not when I visit the jellyfin-web ui. It also works fine with MPC-HC and mpv.

It's extremely choppy, like it plays like less than a second, then micropauses, then does that over and over again. Sometimes completely stopped as if it's buffering.

I've gotten the exact same issue. The web player plays a VP9 video just fine on my laptop and smoothly, but on the JellyFin Media Player (Linux flatpak version) it just lags/gets a lot slowed down. Same behaviour on Android for me either, but even worse.
