DS916+ Emby transcoding performance

[horstepipe 364]

hey

anyone here who owns a DS916+ and can tell me something about the (Emby) transcoding performance?

[chris3452 21]

Pretty poorly currently. Right now maybe could handle one 1080p transcode. The chip uses Intel quick sync for hardware transcodes which emby does not use. But and big but there is long forum in general discussion and at the end they have got hardware transcodes working. If they work it out it transcode ability will match what synology publishes. One side note I don't have one personally just been researching it cause it is the one I am getting next month

Sorry but it is quite unclear what you want to say.

Is Intel Quick Sync working or not?

[chris3452 21]

Not in any releases.  Diffently not on the synology boxes.  

[Luke 38417]

We have a new installation procedure for Synology users. It's very easy and is now on our website:

All Synology users are recommended to use this going forward (if your model supports it).

The chip uses Intel quick sync for hardware transcodes which emby does not use.

 

mhh but here they say that Quick Sync is supported?

Hello @@horstepipe

 

Are you running the new Emby package for Synology - http://emby.media/nas-server.html?

 

If so, can you playback some h264 content and then send your logs using the procedure detailed here: https://github.com/MediaBrowser/Wiki/wiki/Synology-:-How-to-Send-us-Support-Logs

Hey

Sorry I don't own the DS916+ yet.

If I was sure that hardware transcoding works properly in most cases I'd get it immediately.

• Intel processor that supports Intel QuickSync (As a rough guide these are i3, i5 and i7 desktop chips as well as a few embedded chips - BayTrail)
• -or-
• nVidia graphics card that support NVENC (These are the Kepler and Maxwell based GPUs - there are high-end and desktop variants of these cards(4))
• Emby Server running on Microsoft Windows(1)

The last one gets you.  I am going to buy a 916+ next month myself so I will keep watching closely also.

As Synology is useing ffmpeg for hardware transcoding as far as I know, shouldn't it be possible to utilize their ffmpeg while transcoding?

 

As far as I can see, this is what exactly is beeing done on QNAP if I hve a look at their packeges, they have one using their ffmpeg.

 

If some of the devs could comment on that please it would be great.

[Luke 38417]

I don't believe they expose it for other apps to utilize. Nonetheless, we have already added Quick Sync support so you should be fine with that.

Hello @@Vlaves

 

Are you currently running on a DS916+? If so and are running the Emby package for Synology, can you run the steps detailed below...

So, let me clarify.

 

Quick Sync is working on Intel-based Synology boxes?  Yes or no?

 

Thanks.

Hello @@ChannelZ

 

In theory we should be able to take advantage of the underlying hardware, however this isn't something we've been able to get into in any detail, prior to getting the Emby supported Synology package released.

 

Do you own a DS916+?

 

If you do (or anybody else reading this owns a NAS which has QSV support), let us know so we can follow this up in more detail.

I don't.  I was thinking of getting one, but only if QS works.  I currently have a Drobo 5D running off a Dell Optiplex, which I run Windows on.  Quick Sync works great on that (i3-6100), shame very little else is reliable (Drobo, bleugh).

I just bought a DS916+ and setup Emby server. On the playback settings in Emby server management when I set to use Hardware Transcoding, Intel Quick Sync I get a spinning circle that doesn't stop. Currently playing HD 1080p video on nvidia shield client app and ffmeg is running using 25%cpu on synology. 

 

Playback is ok "at best". It stutters with periods where frame rate tanks. 

 

I fI close server settings and come back to the playback tab I see that quick sync is selected. However I cant confirm it is actually working as when I click "save" again it start the spinning circle again and doesn't stop.

Video playback fails unless Hardware Acceleration is disabled.  I am now trying to get Live TV to play via MediaPortal. When playback is successful it uses 98% CPU and stutters like crazy. 

[ChannelZ 3]

So, that to me says Quick Sync doesn't work.  Thanks for confirming, stratumorien.

Hello @@moulin

 

Thanks for the logs, appreciated. If I give you access to the beta channel, would you mind updating to the latest beta and running the diagnostics/send logs again?

 

- James

[moulin 0]

Sure! Happy to help.

[solabc16 379]

Hi @@moulin

 

The latest set of updates have been rolled up into release 3.0.7300, so if you can update to that version and run some tests.

 

If you can run the diagnostics afterwards and send the logs, that would be great.

 

Thanks

[stratumorien 8]

Apologies for losing sight of this. I had gone back to running the server on my intel NUC but recently took the plunge back to Synology as I have had more success with direct play of Live TV. I however am still very interested in functional hardware transcoding on the Synology.

 

I just updated my Synology to .8100 package release just recently. Was the hardware transcoding configuration removed or am I just overlooking it? 

 

EDIT* I just now noticed that it has its own sub menu now, cool! Any progress towards this in the current build?

 

If I can still help by contributing logs from my 916+ I am happy to do so.

 

Thanks,

Brian
