HW Acceleration broken, DS918+

[echoghost 0]

as title, hardware acceleration works fine with plex on the same machine. paid up premium member, HW Acceleration all turned on in the options 

 

for reference the DS918+ has an Apollolake Intel Celeron J3455 which is supposed to be supported

 

log attached, seems like this is the obviously relevant part

Hi there, did you follow our hardware acceleration setup guide?

https://github.com/MediaBrowser/Wiki/wiki/Hardware-Acceleration-Overview

[echoghost 0]

hi,

 

i'm not quite sure how to respond, that's not a guide, it's an overview without action items to complete, therefore no setup

 

did you look at the logs and the quoted output? again plex hardware transcodes just fine 

[Luke 40063]

@@echoghost

Can you attach the hardware detection log as well? Thanks.

[echoghost 0]

i sure can

@echoghost 

• Does hw acceleration fail with all files or just with some?
• How about an h264 source video?

You say that it works with Plex - could you post a Plex transcoder log with hw acceleration?

[echoghost 0]

HW acceleration fails with all files, I haven't found a file it works with

plex logs attached of playing the same file I noted in my first post, as well as a screenshot showing the transcoding in plex

 

 

 

plex.log

[softworkz 4566]

@@echoghost - Sorry for replying late and thanks for providing the Plex log.

 

Could you please try to set 'HW Acceleration' to 'Advanced' and then disable the HEVC decoder (leaving the H264 encoder enabled) and see what happens?

Thanks

[echoghost 0]

Apparently, No i can't, I don't have any options to do that, see attached image. the forum wouldn't let me actually just paste the image in so I had to attach it..

 

[Luke 40063]

Please attach the hardware detection log. Thanks.

[echoghost 0]

i will if this attach button ever works

@@echoghost - There are no hw acceleration devices available. That's different from the hw detection log you posted earlier (16 Oct). Did you make any change to your system?

[echoghost 0]

I haven't made any changes. Plex is also still hardware transcoding just fine on the same NAS. it's only emby that has these problems 

[Luke 40063]

Can you try rebooting the NAS and then try what softworkz asked? Thanks.

[chacawaca 109]

For information 4.3.0.19 with DS918+, i dont have problem with HW.

[echoghost 0]

Restarted emby not the entire system (not possible for now).

That made emby realise there were codecs available, HWAcceleration now seems to work with HVEC decoding enabled or disabled. I've not rebooted the system or updated anything at any point so I imagine there is still a bug, I just can't trigger it anymore

Hi all,

 

I just updated to premier to have HW aacceleration on my DS918+. But I also have problems. The framerate is below 20 for transcoded videos.

 

Any suggestions?

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

I figured out that it is not for all files
I will attach a hardware detection file and three ffmpg transcode files: 2 where playback is fine and one where it is not ok.

@@frotzamuta, have you read the troubleshooting section of our hardware acceleration wiki?

[frotzamuta 0]

ok, got it. Switching of the forced subs of the video helped.

Thank you!

[Luke 40063]

Thanks for the feedback.

Hi guys, having the same issue with my DS718+, its HW acceleration is broken, so it attempts a SW transcode thus using 99% processor power on a single 720p transcode. Tried the suggestions about switching off the DEcoding setting and it's still the same. Please fix!!
