Mine is blank as well... SynoCommunity-Package v4.3.1.0 on DS918+ and all transcoding-jobs are running in software-mode.

eyeSome 1 Posted February 25, 2020 Share Posted February 25, 2020 Did you explore clicking on Linux? Hey Luke, I did! But there is nothing helpful for me. Its said, that the Intel CPU used in Synology DS918+ is supported everywhere, but for me it's not working and I have no idea why. In plex it's working fine with hw.

eyeSome 1 Posted February 25, 2020 Share Posted February 25, 2020 (edited) Please attach the hardware detection log. Thanks. Just found this in the acceleration log: "Error": { "Number": -1, "Message": "Failed to open the drm device /dev/dri/renderD128" } Looks like thats the error I'm facing... what's needed to have the emby-server giving access to this device?

eyeSome 1 Posted February 26, 2020 Share Posted February 26, 2020 Hey together, found the reason: First... My embysvr-User wasn't a member of the group "video" within synology DSM. After that I restarted emby and it did not work either. The reason: The user-permissions are not getting updated when you're just restarting emby. You need to stop and start emby and then the permissions got updated. Now I have hw acceleration working! Best regards! 1 Link to comment Share on other sites More sharing options...
Brudertac 15 Posted February 26, 2020 Share Posted February 26, 2020 Hm, on my Sys the embysrv User is NOT Member of the Video Group. HW acceleration work fine... @luke Is it recommended / needed to add embysrv to the Video Group on Synology Systems? Thanks. 1 Link to comment Share on other sites More sharing options...

eyeSome 1 Posted February 26, 2020 Share Posted February 26, 2020 (edited) Something strange happened on my system. When I checked the permissions of /dev/dri/ before it looked like this: $ ls -al /dev/dri/ total 0 drwxrwxrwx 2 root root 100 Feb 9 22:03 . drwxr-xr-x 13 root root 18940 Feb 18 17:29 .. crw-rw---- 1 root video 226, 0 Feb 21 16:38 card0 crw-rw---- 1 root video 226, 64 Feb 21 16:38 controlD64 crw-rw---- 1 root video 226, 128 Feb 21 16:38 renderD128 In this case it's needed to be member of the group "video" to access the renderD128. I now checked again and it looks like this: $ ls -al /dev/dri/ total 0 drwxrwxrwx 2 root root 100 Feb 9 22:03 . drwxr-xr-x 13 root root 18940 Feb 18 17:29 .. crw-rw-rw- 1 root video 226, 0 Feb 21 16:38 card0 crw-rw-rw- 1 root video 226, 64 Feb 21 16:38 controlD64 crw-rw-rw- 1 root video 226, 128 Feb 21 16:38 renderD128 With this configuration it's NOT necessary to be member of the video-group because "any" can access the driver. But this does not look very safe to me. It looks like that something is changing the chmod of the files, but I don't know who or which process did this. For now I'm on the safe site with the user beeing member of the group. When adding the user I noticed, that the service-user of my plex-server is already member of this group.

eyeSome 1 Posted March 23, 2020 Share Posted March 23, 2020 Hey @Luke Thanks for asking! For me the problem is solved. But for others rushing into the same problem there should be a small NAS FAQ somewhere mentioning that it "may" be needed to add the emby-user to the video-group. Best regards!

Jturquette 0 Posted September 19, 2020 Share Posted September 19, 2020 Hi there, new to Emby. I have been looking and do not see a synology section to the hardware encoding section. is this updated? My situation is the following: running emby server on a synology NAS DS418 play. I have a stutter during the playback of lossless MP4 video file created in M4V converter plus.. I use this program to remove the DRM of my itunes content to make it available to my apple TV 4th generations. I have tried many variants of DRM removes formats to try and combat this problem. I find that Lossless MOV files work without the stuttering because the file goes from direct play to some type of transcoding. I am wondering if I need to get a premeir subscriptions to enable the hardware acceleration. Link to comment Share on other sites More sharing options...

Jturquette 0 Posted September 20, 2020 Share Posted September 20, 2020 Aaah, I see. Is hardware acceleration supported with the synology NAS devices? (DS418Play) Does it make a difference with direct playing wersus direct streaming, versus transcoding? Thanks for quickly responding. Link to comment Share on other sites More sharing options...
Luke 37028 Posted September 20, 2020 Share Posted September 20, 2020 Hardware acceleration is used when transcoding. When direct playing or direct streaming, there's no transcoding involved, thus no need for hardware acceleration. Link to comment Share on other sites More sharing options...
