GPU Transcoding (Intel QuickSync and nVidia NVENC)

[Gerrit507 24]

I've just swapped my J1900 for a J3455 mainboard. With the old mainboard I was able to transcode h264 with vaapi fine. Now that I've the newer mainboard that acutally supports a lot more codecs, has a faster cpu and gpu, I'm not able to transcode h264 with atleast 1x speed anymore. It's ubuntu 16.04 with Kernel 4.4-78. I'm absolutely clueless...

 

And on Windows with qsv I'm getting the following result:

[hevc_qsv @ 0000000002602f20] Could not load the requested plugin: 15dd936825ad475ea34e35f3f54217a6

I've made a fresh install of Ubuntu Server 16.04 now.

 

With the ffmpeg build that comes with emby or any build from https://johnvansickle.com/ffmpeg/ vaapi doesn't work at all in emby.  I'm getting: 

No VA display found for device: /dev/dri/renderD128

And emby falls back to libx264...

Although if I run the same ffmepg build as sudo like this

 ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -i /home/tv/samples/jellyfish-120-mbps-4k-uhd-hevc-10bit.mkv -f null -ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -i /home/tv/samples/jellyfish-120-mbps-4k-uhd-hevc-10bit.mkv -f null -

It works fine, but only as sudo...

 

The strange thing is that with my own ffmpeg build emby doesn't give any errors like above 

But even when it's able to transcode it's so extremely slow. Some h264 videos are transcoded faster than 1x, but most of my videos are way below 1x... Is this a driver issue or what?   CPU usage is very low and GPU usage is about 40%... I've manually installed xorg and openbox by the way and emby is in the video group...

Are you sure you are running the johnvansickle build from command line? It looks like you're running the system ffmpeg. You would have to use the absolute path to run the version that comes with emby or any other version you download.

 

When I tried, the johnvansickle version did not support vaapi at all. He confirmed in an email that vaapi doesn't work in fully static builds. I also confirmed that by building a static and a shared lib one with the same libraries and ffmpeg version. The static one does not work with vaapi even on the same machine it was built on.

 

You may have installed ffmpeg from the ffmpeg3 ppa as that one works with vaapi and would be called without an absolute path.

I was in the path of the ffmpeg build. There was no ffmpeg package installed. The only reason which I can think of is that it called my self compiled version located in /usr/local/bin...

Good point though. Why does it still output that it supports vaapi when it actually doesn't? 

 

EDIT:

I want to quickly summarize my results

 

Ubuntu with vaapi:

hevc -> h264 working

h264 -> h264 working

 

Windows with qsv:

hevc -> h264 completely broken in ffmpeg, see https://trac.ffmpeg.org/ticket/5899 and https://patchwork.ffmpeg.org/patch/286/ They claim that it works, but no it doesn't...

h264 -> h264 working

 

I think that the HD 500 in the J3455 is just too weak to transcode on the fly...

Can somebody confirm if a HD 630 for example is able to transcode two hevc -> h264 at the same time?

[aptalca 70]

To run the ffmpeg script/binary in the current folder, you can use "./ffmpeg"

 

./ is short for the current folder location

 

I have the hd630. Tested it with about 6 h264 to h264 simultaneous transcodes and it was chugging along fine. Didn't have any hevc so didn't test that.

 

Been spending most of my time optimizing and testing an ubuntu based docker build that supports both vaapi and nvenc. It's coming along nicely.

You're absolutely right, it called the one in /usr/local/bin   

 

I guess I might buy a new board and cpu then...

 

Which docker build do you use? Does the official one not support vaapi?

Since you did a new OS install, you need to add the user that runs Emby (the user is probably called "emby") to the video group.  This gives access to the device.  This is also why you see it work as sudo.

 

Also, you have newer hardware - you probably now need newer video drivers and libva.  Using the LTS branch of Ubuntu, you won't have that automatically.

I added emby to the video group of course... I also tried newer drivers without any change.

Hi someone from the AMD AMF Team released a preview of ffmpeg with amd amf support for gpu transcode of hevc files.

 

https://www.xaymar.com/2017/08/16/amf-encoder-plugin-2-2-x-and-amd-driver-17-7-2/

 

I copied the file into the Folder:

 

C:\Users\Egis\AppData\Roaming\Emby-Server\ffmpeg\20170308\

 

But there isn't any option in the Hardware acceleration tab to choose AMD Transcode.

 

Are there additional changes in Emby required to work with amd cards, or which option do I need to choose ?

 

Thx & Greetings

Vaapi on Linux partially supports AMD hardware

 

https://wiki.libav.org/Hardware/vaapi#Hardware_Support

 

On Windows it's not possible at the moment with emby. I saw in a comparison video that the quality of AMF is really bad though... If you want best quality nvidia is the way to go...

Those are two different input files so it's not exactly a 1:1 comparison. You do not need to use the decoder to use the encoder and vice versa.

[eTomm 4]

Yes sure, I am aware of that. The problem is that if I enable the HEVC decoder and the h264 encoder it does not work. And I tested even the encoder itself with the software hevc and it was not working.

 

Now I updated ffmpeg and emby to the latest release and I could make it work the soft hevc decoder with the qsv h264 encoder. But when I enable the hevc decoder with or without the qsv h264 encoder I got this:

Where did you get that? that is only a snippet of a log so I don't even know where that came from. Thanks.

Hi all,

 

If I undertand this thread correctly, the mentioned tests are running on linux?

 

Any status of QuickSync encoding working well on Windows10, and if it's working out-of-the-box, or if it requires custom ffmpeg builds?

 

Thanks-

Jennice

[Jennice 19]

Hi all,

 

I think I have QuickSync transcoding working on my i7-3770, but I think there might be a buffer or ffmpeg issue. It's the current build (v31, 2017-09-20)

I start a stream on the web browswer player, and it defaults to direct (I'd like to be able to change that, but that's another issue I guess).

 

I then set the quality to 4 mbps, and the CPU hovers at approx. 40-50% usage.

 

after a bit of watching, if I set the rate to 2 mbps, the same (buffered?) part plays once again at reduced quality, but now the CPU is maxed at 95%, as if it's still working on the "old" transcode stream of 4 mbps, while also working on the newly selected 2 mpbs. I haven't tried without QuickSync, as my cpu can't go beyond ca 2 mbps transcode without QuickSync support. Awaiting the 8.gen Intels!

@@Jennice, best thing to do is follow the guidelines in how to report a problem. thanks !

This sounds an awful lot like the problem I was seeing where FFMPEG did not close the previous transcoding problem when another process was started.  One way to do this is to seek the client using the scrub bar.  See this post.

The interesting thing is that the second stream seems to start at the same spot (time in live tv), as the first one did.

 

I don't have a clue as to how ffmpeg works, but it's like the second transcode stream works on some kind of buffer file created by the first transcode stream, and not on the live input from the tuner.

 

If ffmpeg creates a buffer file for transcoding, my guess is that it's not cleared when ending the first ffmpeg request. (I used the browser window as viewer).

I played a bit around, and it seems to happen no matter if I use QuickSync encoding or "just" CPU.

Checking somthing

Just downloaded and updated to 3.2.32.

 

The double-buffer issue seems gone, but there's something that makes me wonder.

 

Now, without QS support, I can manage to transcode to 720 / 2 mbit.

With QS support, I have the same limit, but my CPU usage is maybe 10% HIGHER when using QS, and the CPU usage is much more uneven over time. Peaks at regular intervals). Without QS support, it's very constant CPU usage %.

 

My CPU is i7 3770. According to a wiki page I found on Intel CPUs, the 3770 is from the first generation to support QS (on limited number of formats), so maybe this first generation QS is just not worth it?

That is potentially a true statement, yes.

Can someone please show an example of, what they're capable of transcoding on a 7.gen i5 or i7 (stock clock freq's, not on LN2 cooled monsters) 

Personally, my 3770 only manages 2 - 2.5 mbit 720p before occasional stuttering. The CPU usage meter in Win10 says it's 40% - 50% load, but going higher causes stutter, despite the CPU load monitor not hitting 100% (!?).

Could it be that the load monitoring is just too slow to catch transcoding peak loads?

 

Any way to show trascoding speed relative to "real-time" (obviously this should never get below factor 1)?

Rather than look at a new CPU why not consider a NVIDIA Pascal video card?
