Hardware Transcoding

[taliaferro]

Good morning folks,

I've been setting up a Jellyfin instance with a new Arc A310, and I'm having a hard time getting hardware transcoding with QSV to work.

Relevant specs:
Distro: Debian 12.6
Kernel: 6.7.12+bpo-amd64 (from bookworm-backports)
Jellyfin version: 10.9.7+deb12

When I attempt to stream a video with QSV hardware acceleration enabled, I see the following error:

[av1_qsv @ 0x55916eda0040] some encoding parameters are not supported by the QSV runtime. Please double check the input parameters.
[vost#0:0/av1_qsv @ 0x55916edd8880] Error initializing output stream: Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height


I'm not sure what to make of this -- I don't think the parameters Jellyfin is setting are unreasonable but it's a little hard to say. The command it's running is as follows (each argument on a separate line for legibility):

What troubleshooting steps would you recommend I try?
