For plex to use the second transcoder I had to edit a config file in the plex directory...

let me know if more information is needed.

#2

Can you screenshot how this appears in QNAP under Resource Monitor > System Resources > Graphics Card

#3

I think the fix is something like this:

https://forum.qnap.com/viewtopic.php?t=167052&p=822648#p822456

If I understand you're trying to use nvidia gpu encoding? That requires libcuda which cannot be found above:

I'll try this and report back. Thanks!

D129 won't work. But it looks like nvenc is working now?

#8

my over my head with this sw trouble shooting I'm EE. Little to no linux exp. .... When I monitor the resource panel external graphics card usage for plex (lifetime pass holder) and Channels it just shows 0.0%.. plex was working on my QNAP TVS672N but it crapped out and QNAP sent me a 672XT. haven't gotten plex hd transcoding to work again with the new NAS (followed the same process above, but don't think I needed too) but was also was looking at getting the external gpu hardware transcoding working for Channels DVR. maybe ill try again tomorrow.... thanks for the help!!!!

#9

This message means the gpu is being used.

#10

Channels DVR activity shows transcoding is happening when using away from home but it's not using the external GPU from what I can tell. Im inferring this because in Resource Monitor > System Resource > Graphics Card there is no activity when this transcoding is occurring. I'm not even sure this is a Channels DRV issue cause Plex will not work as well. but like I said above I had Plex hardware transcoding (on external GPU) working before my QNAP TVS-672N died and was replaced with TVS-672XT. (had to remove the thunderbolt card to use my external Video Card but have never seen Channels DVR utilizing the external graphics card... oh well.
