Hi,

 

I have been fiddling around with this for too long, so here is what I did for all you after me:

 

  • Activate backported sources
  • Install backported kernel - reboot
  • Install all the packages needed for Hardware Acceleration from backports (perhaps not all of them are neccesary):
    mesa-va-drivers va-driver-all vainfo i965-va-driver mesa-vdpau-drivers libgl1-mesa-dri libgl1-mesa-glx libglapi-mesa libvdpau-va-gl1 libva-drm1 va-drive vdpau-va-driver libva-intel-drivers libdrm-intel1
  • DONT use the static ffmpeg build linked somewhere in the install guide. For me it did not work at all. If you did, switch from custom ffmpeg to system installed in your emby interface.
  • Except install ffmpeg from debian backports
  • activate VA-API in emby

 

Thats it, I had very little idea how to do this when I started trying this. As wrongly suggested to me you dont need any xorg stuff.

Now we only need this issue fixed in stable :)

 

Hope I can help someone, also correct me if something is not right here.

hm, seems I posted that too early. Vaapi transcoding with the exact same command line as in the emby logs works with ffmpeg, but not in emby itself..

 

It always crashes with something like that in the logs:

Any Ideas?

That generally means the client video player disconnected because it saw something it didn't  like.

So what can I do to fix this? Open an issue on github for that?

 

As I said ffmpeg is trasncoding the files with the exact same command, and vaapi is beeing used for that. Could it be my browser?

I did, it is working flawlessly, the thing is I need Hardware Acceleration for transcoding 1080p movies, my CPU alone is too weak for that. But I guess I have to decide..

 

Either beeing able to watch most of the movies, not the 1080p ones I have to transcode, or beeing able to play some of them, but not all because it seems that not all codecs are supported with VAAPI. Or is there something else I could do?

Install Ubuntu 16.04 instead of Debian and the ffmpeg build from the other post about vaapi.  It works great in that distro.

I have some other services running on this server, so I cant just switch OS, but perhaps I can run Ubuntu inside of an container. Or the more important question would be, can I have vaapi support inside of that container? Will try that eventually :)

By other ffmpeg build you mean this? https://johnvansickle.com/ffmpeg/

Thank you anyways!

No, the one mentioned here:  http://ubuntuhandbook.org/index.php/2016/09/install-ffmpeg-3-1-ubuntu-16-04-ppa/
