Stuttering Playback for Certain mp4 Files on New Devices #4055

Open Nerokor opened 1 week ago

Nerokor commented 1 week ago

Describe the bug

I am experiencing an issue with media playback in the Jellyfin Android TV app where certain .mp4 videos stutter, while the audio plays fine throughout the playback. This issue does not occur with all .mp4 files, only specific ones. Notably, the problematic files play fine on a range of older Fire TV Stick models without stuttering, but they stutter on the newest 16GB Fire TV Stick model and the Insignia TV model.

Additionally, if I take the troubled .mp4 files and recontainer them into .mkv files using MKVToolNix, they play fine on all devices without any stuttering.

I've encountered this same issue. It only affects some mp4s and turning them into mkv files does indeed fix the issue.

But the problem is not only happening for me on my TV, it also affects playback in the web player and on my Android phone. I've since tested the problematic files by playing them directly via a plain html file with a video element, directly from my laptop in Edge (chromium) and the issue is present. (mp4 file stutters, mkv plays smooth).

Also note that I was able to get the file to play smoothly on my TV by forcing the video to open in an external player (ie. VLC).

Don't know if it's that some mp4 files are just broken, or there's a bug in the jellyfin Android/AndroidTV playback that is also a problem in Chromium browsers.
