SOLVED: Error on trying to transcode hevc (native) -> h264 (h264_nvenc)

[whiskers]

Debian 12
Jellyfin.Server 10.8.13.0

When I try to play an h264 file using the web client, I see this error in the transcoding logs:

Code:

Conversion failed!

I can reproduce the error by running the ffmpeg command in my terminal. When I google the error I see: https://stackoverflow.com/questions/5202...lter-error

which says I need to pass in "hwupload_cuda" along with the filter. When I add it I get the following output in my terminal:

So (best I can tell) it says hwaccel initialization error but then goes ahead and does the decode anyway?

Anyone have ideas on how to resolve this?

A simple search of the support matrix would have told me that unchecking hevc would be enough to fix the error
