Docker Nvidia T400 decoding

[mattb]

I'm in the process of adding nvidia support to my jellyfin docker container and looking for some confirmation.

Believe I have everything setup, however when I run nvidia-smi, I'm not seeing the ...jellyfin-ffmpeg/ffmpeg process.  And this is making me unsure it's working.

I also see the gpu and memory being used (screenshot)

From what I understand, I should see this in the ffmpeg transcode logs (which I do):

Stream mapping:
  Stream #0:0 -> #0:0 (hevc (native) -> h264 (h264_nvenc))
  Stream #0:1 -> #0:1 (aac (native) -> ac3 (native))

Also see this in the log, which also indicates hwaccel:
