HW transcoding on Synology failed

[lilies1]

Hi there, I’m using Jellyfin (Version 10.8.11) on a Synology DS224+ (latest DSM) in a docker container. Most of my videos are in 1024i H264 format - however I’m not able to hardware transcode this specific format. The error will be always that the client is not compatible with the video format. I already tried to switch to the latest Jellyfin version - no change. Other formats are working fine with HW transcoding.

Are there any restrictions on interlaced video formats/codecs? What needs to be done to get it work? Attached the error dump and the section for HW decoding in the compose file.

Thanks for ideas…
Andreas

Can you share how your transcoding settings look like within Jellyfin's dashboard?

[TheDreadPirate]

Try passing in just "/dev/dri" into the container. The Intel driver will figure out the rest.

And can you share the full ffmpeg log?

Here we go...hope you don't mind that settings are in German....

Versus what I put in today...how should the statement look like? What's your suggestion?

devices:
      - /dev/dri/renderD128:/dev/dri/renderD128
      - /dev/dri/card0:/dev/dri/card0

Down below you'll find the full error message. As I switched to Jellyfin 10.10.6 meanwhile, the error message looks a bit different now.
