- Enter the NVIDIA Quadro P2000 Graphics card. While it’s not the biggest baddest kid on the block it is the first card in the Quadro line from NVIDIA with H265 support that allows for an ‘unlimited’ number of simultaneous streams/transcodes, and it only consumes a maximum of 75 watts TDP.

I’ve run into a problem with getting HW transcoding to work on a Debian 10 server.

GPU: Nvidia Quadro P400
Nvidia driver version: 440.100
HW acceleration is enabled in PMS settings.
When running a 1080p to 240p transcode (for testing), both Nvidia-smi and nvtop pick up the transcode, but let the CPU do all the work (328%, 4 core).
Same with 4K to 1080p but with 100% CPU load (400%) and choppy playback.
Nvidia Quadro P400 Plex Vs
3 Kepler supports some optional 11.1 features on feature level 110 through the Direct3D 11.1 API, however Nvidia did not enable four non-gaming features to qualify Kepler for level 111. 88 89 4 The GeForce GT 705 (OEM) is a rebranded GeForce GT 610, which itself is a rebranded GeForce GT 520. The NVIDIA Quadro P400 is based on NVIDIA pascal architecture and delivers up to 2x more visualization performance than the NVIDIA maxwell-based Quadro K420. Three DisplayPort outputs provide more Display connectivity than the previous generation. With more Memory bandwidth than the previous generation, customers can work with larger datasets.
nvtop shows: -hwaccel:0 nvdec -hwaccel_fallback_threshold:0

Does anyone know what I can do?
I’ve looked into dependencies for Debian (https://wiki.debian.org/HardwareVideoAcceleration)
According to this, two packages are necessary:
libnvcuvid1
libnvidia-encode1
I can’t install them because they conflict with the latest Nvidia driver (screenshot).
