Hardware Acceleration

I'm suffering with Plex as it struggle to play 4K movies on my Qnap TVS-472XT, here is my post on Plex Forum for your reference:

https://forums.plex.tv/t/hardware-acceleration-on-qnap-tvs-472xt/424102/27

 

My question is, does Emby supports GPU installed on aforementioned Qnap, or I need to install them on VM like Plex requires? So if I purchased and installed MSI GeForce GTX 1050 Ti 4GT LP, will Emby recognize it and utilize it directly, or I should install Emby on VM to achieve that?

 

One of the Plex Forum members tried that - see above link - and he says that with GPU on board Emby performance becomes worse actually although he confirmed that Emby recognized the aforementioned graphic card.

 

Could you please advise? I know hardware acceleration requires premium account, I already purchased one. But before purchasing the Graphic Card I would like to confirm if Emby will work fine with it.

 

Thanks

Hi, it should work but we have not yet tested Nvidia ourselves on qnap. It's very new following the recent qnap qts update. Thanks.

HI!

Im here TOO! =) (From Plex)

Yes. I have all latest Qnap FW (4.4.1) and Nvidia kernel (4.4.1) + drivers (2.1.3)

 

Emby recognizes GPU (1050ti) beautifully when GPU is assigned to Container. But nothing is running is Container.. Just plain qpkg program from Qnap Shop.

 

If I put GPU as first for all decores, instead VAAPI, I get these:

For 4K HEVC it runs mu i5-8400T 100% and GPU only 13% and it uses 1.5GB/4GB.

 

If I put VAAPI first:

10-35% CPU, GPU 0%

 

Good thing is That When Plex puts 4K HEVC to transcoding on my 4K Samsung and XBOX... EMBY direct streams them, even with subs!, so 0% CPU, 0% GPU... =)

 

But anyways... My point was that something is not done right, because when video is transcoded in GPU, it sends it back to CPU and that pushes CPU to 100%...

We'd have to look at an example ffmpeg log but most likely a feature is being used that requires sending it back to the CPU.

 

If it's burning in subtitles then that is most likely why. That's something you want to avoid.

I did more testing and Now I could not get anything to load CPU to 100%
These 2 are the hardest I could find, both CPU 20-35%, GPU 10-15%
They Are 4K HEVC HDR 10.. and with both I get lost of green blocks on screen..
 
EDIT: ADDED two ffmpeg reports in ZIP

Could you please elaborate more? So Emby same as Plex, will not recognize the graphics card except with the installation and setup of VM? If so, then what is container exactly and how to set it up? I'm so sorry but I have no technical background about this at all. Also did you run the 4K HDR movies with image-based subtitles? IF you can let me know how to achieve best result out of Emby and Graphics Card I would be thankful.

EMBY WILL recognize. When graphics card is added, Qnap will ask if you want to add it to VM or Container. Choose Container. But there is no need to use any Container version or VM for EMBY..

 

I did run EMBY Theater on my PC and those 2 sample files were 4K HEVK HDR, with subtitles. both samples were transcoded =)
