Correct settings for transcoding

[l0fL 0]

Hello everybody,

 

I've a selfmade NAS (xpenology) with an Intel Pentium Gold G4620 Kaby Lake CPU und 4GB Ram. DSM & Emby are up to date. I used the "normal" emby from this repo https://synology.emby.media/?package_repository=360efc6e-de72-4073-b603-2bfbd7001586 .

When I want to transcode a movie my cpu is about 80% workload. If i reduce the Quality i've round about 55%.

It doesnt matter which settings i use (QuickSync, VAAPI...)-, it's always the same. Actually my cpu would have to decode in hardware, but it doesnt seem that way.

How can i transcode in Hardware and yes the hook on hardware encoding is set.

 

Thank you!

Hi there, can we please look at an example? Please attach the information requested in how to report a media playback issue. thanks !

My workload

The small slope in the beginning was transcode at 1080p 60 Mbit/s and the increase was 480p. The file is a native 1080p file.

I have the same result if i choice Quick Sync.

In this log vaapi was used.

But why is my CPU on 80%? If it were Hardware Decoding it schould be at 5-10%.

It's hard to say, but it is being used.

What is the right attitude then? Are my settings correct?

That's why I bought a Kaby Lake CPU.

Have you added user emby to the video group on the Synology? Beyond that we'll see what @@solabc16 thinks.

 

Thanks !

Hello @@l0fL

 

Which XPEnology setup are you using and what DSM version?

Hi Luke

 

I've just been setting up Emby on a DS415Play Evansport the last few days. 

 

I installed from package center, and after did the SSH procedure of changing ffmpeg version or whatever it was.

 

 

Can you explain a bit more what you mean by what you say here ?

 

I have no user "emby", but package installed created user "embysrvr". It is by default only a member of the "users" group, one of the three default groups (others are "administrators" and "http (system default group for web services)". 

 

So should there be a user called emby and or a user group called video after package install ?

 

Or do you just mean that the embysrvr user must be gives read/write access to the video shared folder ? Thanks for your help.

Hello @@eevv

 

You don't need to make any further changes within DSM, other than setting up your library permissions as detailed on the Wiki here : https://github.com/MediaBrowser/Wiki/wiki/Synology-:-Setting-Up-Your-Media-Library-Share

 

Let's continue on the other thread if necessary, as this one relates to XPEnology based systems : https://emby.media/community/index.php?/topic/43282-hw-transcoding-on-evansport-ds415playds214play-machines/?p=603485

Hello @@l0fL

 

The problem we can see from the log is...

[AVHWDeviceContext @ 0x869c00] No VA display found for device: /dev/dri/renderD128.
Device creation failed: -22.
Failed to set value '/dev/dri/renderD128' for option 'vaapi_device': Invalid argument
Error parsing global options: Invalid argument

...from other reports, getting GPU support working seem to be a little hit and miss with XPEnology; at the moment at the least.

 

From an SSH session can you run the below and post the output here:-

cd /var/packages/EmbyServer/target/ffmpeg/bin
sudo ./vainfo

This is my output

 

error: failed to initialize display

 

 

I've no display at my NAS station. But in BIOS iGPU is on AUTO. Is that my mistake?

Thanks @@l0fL

 

Mentioning @@Joly0 here, who has reported similar findings with getting their XPEnology setup. Primarily, this is an XPEnology 'issue', and I don't mean that in the sense of it being a fault or bug.

 

Have you tried the DS916+ or DS918+ loaders, which target h/w that does natively have GPU support?

 

I don't believe the DS3615xs kernel includes the necessary device drivers, as although the CPU might be capable of supporting h/w transcoding, this model was targeted at 'business' users and hence they were not included.

Is this procedure still required or is this done automatically in new versions?

I am on the DS415play, what would be the correct setting for me?

 

Model: DS415play

CPU: Intel Atom CE5335

Cores: Dual Core

Threads: 4

FPU: Yes

Package Arch: Evansport

It will be more automatic with the next release. Thanks.

Hello @@erikblues

 

There is no native h/w transcoding support available with 'evansport' based systems, there's a couple of posts kicking around on the subject which provide some background.
