I think i have video acceleration problem and i am not sure how to fix. If i check if my system support video acceleration i get this:
Code:
$ vainfo
libva info: VA-API version 1.6.0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so
libva info: va_openDriver() returns -1
vaInitialize failed with error code -1 (unknown libva error),exit
But if i use VLC from terminal, and stream youtube url or open local video file i can see that VLC is using video acceleration. But if i watch the same youtube video in Firefox or watch the same local video file in Kodi i can see that they are not using video acceleration, because they are loading the cpu more than VLC. And hardware acceleration in Firefox is enabled.
I have these packages containing vdpau in the name, installed:
Code:
$ dpkg -l | grep vdpau
ii libvdpau-va-gl1:amd64 0.4.2-1+b1 amd64 VDPAU driver with OpenGL/VAAPI backend
ii libvdpau1:amd64 1.1.1-10 amd64 Video Decode and Presentation API for Unix (libraries)

If i search the repository for vdpau i get this:

Having libvdpau1 installed for two architectures is definitely not right, you'll also need vdpau-va-driver (vdpau-driver-all), and vdpauinfo will come in handy in diagnosing further issues if this won't help.
libvdpau1:amd64 and libvdpau1:i386 are installed automatically from the mx linux updates. I will have to ask their support if i need to remove one of the packages.
I installed vdpau-va-driver and vdpauinfo and now if i run vainfo i get this:
Code:
$ vainfo
libva info: VA-API version 1.6.0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/nvidia_drv_video.so

Does that mean that my system should support video acceleration?
Well, technically it did from the very start, only it was proprietary Nvidia VDPAU acceleration, now you have a standard VA-API acceleration too - provided that 32-64 bit mixup with libvdpau1 is not messing up anything.
There two layers here: proprietary VDPAU acceleration for Nvidia, and some programs - e.g. vlc or mplayer can work with it directly and don't need VA-API at all, and vendor-independent and more widely accepted VA-API which needs drivers to work with VDPAU backend.
