SOLVED: HEVC Stutter on N100 Local Media - Direct Playback. Plays fine in VLC.

[timovarius]

Hello all : )

I run my Jellyfin server locally on a Windows 11 PC for my mini home theater with Jellyfin Media Player as an interface for my media. I previously had a HP SFF Office PC with an i3, 8 gig DDR4 ram, and a AMD Radeon R7 430. All media is stored on an external USB 3.0 hard drive. It worked flawlessly and I played all my media via direct playback. No hardware acceleration required.

I eventually moved to a GMKTek Mini PC with an Intel N100 Processor and 16gig DDR5 RAM. Same set up as above with the USB 3.0 drive serving the media locally and using Jellyfin Media Player to playback direct. However this time HEVC stutters (about half the framerate). I opened the same MKV in VLC and it played back perfectly. H.264 plays back fine in Jellyfin Media Player.

TV is just a UHD 60hz via HDMI

Any advice would be great. I've tried many various setting combinations and nothing changes.

Thanks in advacned.

Can you share your jellyfin logs via pastebin? Is the miniPC running Windows? And how is it connected to your network?

Hello, thanks for your reply. Here is fresh logs created playing back 2 HEVC file and a 1 H.264

I'm on Windows 11, it's connected to the network via WiFi, however all the media is local to the MiniPC running from the USB 3.0 Drive.

It plays back high bitrate H.264 fine, as soon as HEVC is introduced, the frame rate halves.

In Settings > Client Settings, what is "Hardware decoding" currently set to?

In Settings > Client Settings, what is "Hardware decoding" currently set to?

No hardware decoding.

I tried the Intel Sync option and HEVC files wouldn't open.

I assumed because I'm playing the file off a local drive that it would perform similarly to VLC.

Thanks in advanced.

I'm talking about in Jellyfin Media Player. Click on your profile, click "Client Settings", scroll down halfway to "Hardware decoding". Enable, copy, and disable are the three options.

Can you share the ffprobe output of these files? Right now, it is direct playing.

Sorry for the delay. This seems to have completely solved my issue when enabling "hardware decoding" at the client level.

Thank you for your help.
