[SOLVED] Trying to get VA-API working

I would like to get hardware accelerated video decoding to work with VLC or MPlayer.  My AMD Radeon card:

$ lspci | grep VGA
02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cape Verde XT [Radeon HD 7770 GHz Edition]

According to this table it has hardware accelerated video decoding support.

I have installed: xf86-video-ati, libva-vdpau-driver,  ati-dri.

When I run vainfo I get:

libva info: VA-API version 0.34.0
libva info: va_getDriverName() returns -1
libva error: va_getDriverName() failed with unknown libva error,driver_name=(null)
vaInitialize failed with error code -1 (unknown libva error),exit

VLC gives me something similar:

[0x7f38a4c04e18] vdpau generic error: device creation failure: error 1
libva info: VA-API version 0.34.0
libva info: va_getDriverName() returns -1
libva error: va_getDriverName() failed with unknown libva error,driver_name=(null)
[0x7f38a4c04e18] vaapi generic error: Failed to initialize the VAAPI device
Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory

I am missing a driver, apparently.  I'm not sure what that is.  Ideas?

Re: [SOLVED] Trying to get VA-API working

Radeon cards are using vdpau for hardware acceleration. I'm not sure of the status of the 7770 or if you need the stuff from git though. I'm running the git stack through the unofficial [mesa-git] repository including xf86-video-ati-git. It's from lordheavy, so it's a trusted repo.

Thanks for the reply.

OK, I followed this instead:  https://wiki.archlinux.org/index.php/VDPAU

I installed vdpauinfo, and it gives me:

display: :0   screen: 0
Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared object file: No such file or directory
Error creating VDPAU device: 1

Re: [SOLVED] Trying to get VA-API working

You may have to set an environment var to make vainfo find the correct driver.
try running  VDPAU_DRIVER=radeonsi vainfo

% VDPAU_DRIVER=radeonsi vdpauinfo 
display: :0   screen: 0

libva error: va_getDriverName() failed with unknown libva error,driver_name=(null)

I tried all the drivers in /usr/lib/vdpau.  The only output I get is from the driver softpipe.

Re: [SOLVED] Trying to get VA-API working

OK, Solved.

I had a custom xorg.conf.d/20-radeon.conf config file that was using AccelMethod of EXA instead of Glamor.
