I am running the plexinc/pms-docker:plexpass image with a Quadro P400. Hardware transcoding is failing in the Plex application (falling back to software).
I have performed isolated tests inside the container. Generic FFmpeg (installed via apt) can successfully encode using the GPU. However, the bundled Plex Transcoder binary fails to initialize the hardware decoder/encoder chain in the exact same session.
Environment:
- GPU: Quadro P400 (Pascal)
- Driver: 550.163.01
- Image:

Preferences.xml confirms hardware acceleration is enabled:
[goose@Vergil: ...Application Support/Plex Media Server ] $ sudo cat Preferences.xml| yq -p xml | grep "Hardware"

The Environment is valid, nvidia-smi sees the card, and ldconfig sees the libraries mounted by the runtime.

I installed a vanilla ffmpeg (apt install ffmpeg) inside the container to verify the driver mapping. It works perfectly:

When running the exact same logic using the bundled Plex Transcoder binary, it fails to find the decoder libraries, despite listing h264_nvenc as an available encoder via -encoders:
