Plex and GPU refuses to work

[unwavering-judgeship6532]

Hello!  I am beating myself up over this.  I have looked through the forums and googled a ton but I cannot get plex to use my NVidia GTX 970 to transcode.

I  am using linuxervers docker

I have --device=/dev/dvb/ --runtime=nvidia in extra parameters  ( I have a tv tuner plugged in too)

I have NVIDIA_DRIVER_CAPABILITIES set to all

I have  NVIDIA_VISIBLE_DEVICES set to GPU-etc etc

I also have it set to use hardware in plex settings as well   ( i have a lifetime pass)

I have the nvidia drivers plug in installed and using latest branch,  (shows my video card in info)  I also disabled and re-enabled dockers as well.

I try and play a 4k video on an nvidia shield v1 as a test and it just uses my cpu as the transcoder.  

 

Am I missing something???  Thank you!

It may be too old to transcode the files you are working with. Do you have any h.264 files to try?

[unwavering-judgeship6532]

I do.  I was trying what was said to be an h.265 however.  Google and some plex forums said the 970 should be fine?  I can try the 264 and see what happens

the 1080p just does direct play lol.  dang.

The Video Encode and Decode GPU Support Matrix is not listing decoding support for h.265 on GTX 970.

For h265, you need (at least) a GT1030 - recommended is a 1050Ti or newer👍

Intel iGPUs can also handle h265

well darn!!!!  Thanks guys I appreciate the help.  Too bad this PC is a Ryzen 7 1st gen so I will have to look into better cards.  For now I will have to watch the proc % spike during playback on that tv lol.  Thank you!  I'll mark resolved

If all you need is transcoding for a few users, the Quadro T400 or P400 are inexpensive and low power (35W max).  The older Quadro P500 can be found used in the $50-75 USD range.
