Hardware transcoding doesn't seems to work

[nesk_woe 0]

Dear Emby

 

I subscript to Emby Premiere looking for the support of hardware decoding capability of Emby, however, when I follow the guide to setup accordingly. I found the hardware decoding dosen't seems to be work on my NAS. you may check the video record in https://www.bilibili.com/video/BV1wt421A7DJ/?spm_id_from=333.999.0.0. my NAS is using a N5105 CPU it should be supporting h265 decode. and I try Jellyfin, it is working find. may I have your advice on it?

Did you try playing the videos with subtitles turned off? PGS subtitles will force software transcoding.

Here's me playing the same video also with pgs...

Are you sure it is actually enabled as your image above does not show low enough.

Dear all

many thanks for your support, I do try the turn off the sub title, but doesn't seems to work any different. and the transcoding config is properly saved as below. also attached the latest log with sub title turn off for your further check

In the past I have used that same cpu.  It can be tricky depending on what OS and kernel you are using but sometimes the GUC must be turned on by adding "options i915 enable_guc=3"  to: /etc/modprobe.d/i915.conf

If you do a google search on the option above you can find more info and see if it applies to your situation.  My issue was similar, all the transcoding options were there but it wouldn't transcode.

hi wedgekc, thank you for the update, I am running the server from docker,  image is linuxserver/emby:latest, for os, do you mean the os that my NAS is running on? I am not able to locate /etc/modprobe.d/i915.conf within the container.

[wedgekc 12]

Yes, what are you using for your NAS os, synology?  My experience is with Debian.  The command I mentioned would be used on the host with the gpu.  As I understand it, the low power encoder/decoder must be enabled for transcoding to work.  If you can get to a terminal you can try running:  "sudo cat /sys/kernel/debug/dri/0/gt/uc/guc_info" (you may or may not need to use sudo at the beginning) or maybe try "sudo dmesg | grep GuC" and see what is returned .  Sorry, but I don't have any experience with Synology and I don't know if things I am mentioning are even possible to do with it.  

[nesk_woe 0]

Not Synology, it is Chinese band NAS, os call UGOS, I am not able to open the terminal of it to check on that. strange that Jellyfin working normal with similar docker deployment

[guunter 2]

Can you post your docker compose file?

[nesk_woe 0]

sorry， there is no docker compose file could be provide, as I am using a embed docker tool. but if below logs tells the reason why it is failing?

[guunter 2]

can you open a console in the container and use intel_gpu_top ?

[nesk_woe 0]

I can't find such command in the container

Dear helpers

 

many thanks for help, I think I found the root cause, it was still PGS subtitles force software transcoding. but it seems cause by safari, I do turn off subtitle on safari, but it doesn't seems works, however, if I switch to edge, the problem solved.
