QuickSync not working with Coffee Lake CPU

Channels DVR Server Troubleshooting
#1

Just updated my processor to a Coffee Lake CPU, i3-8100, which supports Quick Sync.

Ubuntu 18.04
i3-8100
H370 chipset

However, the hardware encoding button is missing, and my only option is software encoding.

I noticed this in my logs:

[fastdeint @ 0x28b0540] [Eval @ 0x7ffd65adc420] Undefined constant or missing ‘(’ in ‘hardware’
[fastdeint @ 0x28b0540] Unable to parse option value “hardware”

Executing the command noted in the thread gives me the following error:

zack@lotus:/DVR$ ./channels-dvr/latest/ffmpeg -hide_banner -vaapi_device /dev/dri/renderD128 -f lavfi -t 0.1 -i color=black:640x480 -f null -y /dev/null
ffmpeg: intel_memman.c:38: intel_memman_init: Assertion `intel->bufmgr' failed.

What does this command output:

ls -alh /dev/dri

I also confirmed my BIOS has multi-monitor enabled and integrated graphics is on. This computer does not have an add-on graphics card.

I also ran vainfo to see if this provided anything useful:

There’s a pre-release you can try. Hold shift and click Check for Updates

It looks like the intel->bufmgr error is limited to the compiled ffmpeg included with channels. The ffmpeg included with ubuntu doesn’t seem to have this issue:

Also, is there a reason why the hardware button isn’t even an option in this case? What does the channels software use to determine if it should show the hardware option?

#9

I investigated some more, and I’m sure the issue is with the intel-vaapi-driver that is compiled for channels’s ffmpeg.

I created a symbolic link to ubuntu’s /usr/bin/ffmpeg, and the hardware option reappeared in the channels DVR. I am able to play recordings without difficulty, and here’s an example of the log:

Also, for fun, while the hardware transcoding was still an option (before restarting channels), I moved the channels’s ffmpeg back to its original location, and attempted to play a video. The bufmgr assertion error again appeared.

Hope this helps with the debug of your ffmpeg.

#10

Can you try the new pre-release build.

#11

Just updated. Same bug, unfortunately.

Version
2018.08.21.1702

Transcoder still has only “Software” listed as the only option.

Any chance you could give me SSH access so I can try some stuff?

#13

This issue was fixed in the latest DVR release (v2018.08.27.1927).
