Extreme stuttering making all videos unwatchable #330

Open PureTryOut opened 2 months ago

PureTryOut commented 2 months ago

Describe the bug Any video I play using Jellycon has an extreme stuttering problem. This while the same video plays fine using the Jellyfin web interface on my PC, even if the server has to transcode for it.

The machine (a RockPro64) has native support for HEVC/x265 files but even if playing those directly (without transcoding) the stuttering makes it unwatchable.

To Reproduce

  1. Start any video from Jellyfin

Expected behavior The video to play smoothly.

Logs Not sure where to get these from.

System (please complete the following information):

Additional context This is running on a RockPro64 which is officially supported by LibreElec. The connection to the Jellyfin instance is using a direct IP, so everything stays within the network. The connection is a 100MBit line.

Because of this issue I basically can not watch Jellyfin on my Kodi instance.

Are you sure you've configured hardware decoding in Kodi? JellyCon has no impact on playback at all, we just hand Kodi a URL and it handles all the playback on it's own. You'll likely have the same results just trying to play the files locally without going through a Jellyfin server. This sounds like your hardware either can't play the video, or Kodi isn't aware how to reach the hardware acceleration bits.

I mean, this is an official image from LibreElec made specifically for this device, I'd assume hardware decoding is configured correctly by default. I'm new to Kodi, I don't know how I would configure it otherwise.

I'll try to play a file directly tonight but I'd be amazed if that doesn't play smoothly either.

It sounds like either your install doesn't have codec support enabled, the device isn't actually capable of playing HEVC directly, or you have network issues and it can't keep up. The last one seems the least likely, imo.

To look into hardware acceleration (assuming libreelec hasn't moved it, or has another config location), go to Settings -> Player. Switch the settings mode from Basic to Advanced or Expert. This will give you way more options under the Videos section. I don't have any good guidance on tuning this, unfortunately, so I won't be much help there.

Well I finally got the chance to plug in a USB-stick to play the files directly on-device, those play just fine. So hardware acceleration doesn't seem to be the problem.
