AMDGPU hardware decoding/encoding: vdpau or vaapi?

[gradinaruvasile]

I have a Ryzen 3 2200G apu, Debian Testing and with the Mesa 18.0.1 from Debian Experimental i have VDPAU and VAAPI working (although no VP9 and HEVC 4k doesnt work).
I compiled Mesa from mainline git (18.2.0-devel ) and now i have no VDPAU working but VAAPI works perfectly well and it has also working VP9 and HEVC decoding (tested with 4k@60fps clips).
Before my r600g A8 had VDPAU implementation, VAAPI was working via a plugin.

Did the amdgpu driver switch to VAAPI from VDPAU?

Edit: actually 18.2.0-devel instead of 18.0.2

Hmm. After compiling mesa do u install also needed vdpau library? This should be called (depends on disto): libvdpau1, vdpau-driver-all and mesa-vdpau-drivers.

Umm. Since then i restarted the computer and just checked it and works...
The interesting thing is that now vaapi seems to me it is directly used, not via the vdpau plugin as before (it was buggy and ate much more cpu than the vdpau plugin directly.)

But VDPAU does not support VP9, whereas VA API does:
