HW acceleration doesn' work with h264 coded videos

[lordmarck]

I have an unraid server with an rtx 1660 for hw transcoding and accelaration. Jellyfin works great except when it comes to videos with H264 codec. Those video go through the cpu. Anyone has any idea what could be the reason? I'm pretty new to both jellyfin and unraid so please bear with me.

[TheDreadPirate]

Is the video direct playing? If it direct plays on the client, the GPU will not be used. You should only see GPU usage with transcoding.

[lordmarck]

No I tried to change the bitrate but it keeps going through the cpu.

[TheDreadPirate]

Can you share your ffmpeg and jellyfin logs?

[lordmarck]

where can i find them?

[TheDreadPirate]

The container path is /config/logs, IIRC. So wherever that is mounted. You can also see your logs in the dashboard.

This is the ffmpeg log

the jellyfin log is very long. Do you need all of it or just a piece?

[TheDreadPirate]

That log indicates that it is transcoding just the audio (CPU only). The video is untouched.

Code:

Stream #0:0 -> #0:0 (copy)
Stream #0:2 -> #0:1 (ac3 (native) -> aac (native))

[lordmarck]

that's weird. I was definitely watching at lower res.

the video is at 1080 60 Mbps an i was watching at 720 8 mbps

Make sure you are selecting the ffmpeg log that corresponds to that activity.  Also, upload the log to sourcebin instead of pasting it directly in a post here.
