Good day everyone! (c)
I have a problem with this configuration:
Primary video card: Intel core i7 - i965 driver
Discrete Video card: [AMD/ATI] Topaz XT [Radeon R7 M260/M265 / M340/M360 / M440/M445] (M445) - radeonsi driver
The problem is, when I use just VA-API with i965 driver, vainfo shows me that it is working:
$ echo $LIBVA_DRIVER_NAME
i965
$ vainfo
libva info: VA-API version 0.40.0
libva info: va_getDriverName() returns 0
libva info: User requested driver 'i965'
libva info: Trying to open /usr/lib/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_0_40
libva info: va_openDriver() returns 0
vainfo: VA-API version: 0.40 (libva )
vainfo: Driver version: Intel i965 driver for Intel(R) Kabylake - 1.8.3
vainfo: Supported profile and entrypoints
...
But when I try to use VDPAU via VA-API it shows an error that is unknown to google
$ echo $VDPAU_DRIVER
va_gl
$ vdpauinfo
display: :0 screen: 0
libva info: VA-API version 0.40.0
libva info: va_getDriverName() returns -1
libva info: User requested driver 'i965'
libva info: Trying to open /usr/lib/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_0_40
libva error: /usr/lib/dri/i965_drv_video.so init failed
libva info: va_openDriver() returns -1
API version: 1
Information string: OpenGL/VAAPI backend for VDPAU
Video surface:
...
For now I use:
$ echo $VDPAU_DRIVER
radeonsi
$ echo $LIBVA_DRIVER_NAME
i965
$ echo $DRI_PRIME
1
That will enable discrete video card every time VDPAU application is started. Sometimes I need that, sometimes I need battery life with the ability to start VDPAU applications.
Please advice!

That's because you're trying to use radeon card with i965 (intel) driver for VA-API (libva info: User requested driver 'i965').
It's noted in troubleshooting section on VA-API wiki page that you need to specify which VDPAU driver you want to use if you plan to also use libvdpau-va-gl.

Didn't he try that? He'd like to use the intel card, but it crashes, so he currently uses radeon for vdpau.

No, he actually didn't, unless i misunederstood him - he has a hybrid graphics setup on a laptop with Intel IGP and Radeon DGP ([Radeon R7 M260/M265 / M340/M360 / M440/M445] is a mobile chip used in laptops), error appears when he tries to run the player with DRI_PRIME=1 without specifying the appropriate VA-API driver for discrete card (radeon).

Sorry for a confusion.
Actually no, I'm forced to use DRI_PRIME=1 to enable VDPAU radeonsi driver. But when I don't want to use discrete card it shows the error with those variables:
DRI_PRIME=0
LIBVA_DRIVER_NAME=i965
VDPAU_DRIVER=va_gl
This configuration should not use the discrete card, I will end up with Intel that works via VA-API but it doesn't via VDPAU -> VA-API

Ok, it seems I did misunderstood you, sorry about that.
On the forums there are several occasions of people reporting that their environment might be ressponsible for vainfo/vdpauinfo not being able to find appropriate driver ( like https://bbs.archlinux.org/viewtopic.php?id=184573 ). Long shot, but that's all I can think of.

It didn't help.
I run strace vdpauinfo to understand what is going on and I received a strange error of missing file libatiadlxx.so. As google said this file is provided by proprietary amd driver but this is a mastery why it is required by VDPAU when it is using VA-API i915 driver.
But the problem is in wayland session, I guess. I switched back to X11 and this configuration works fine with no errors reporting.
And using
$ echo $VDPAU_DRIVER
radeonsi
$ echo $LIBVA_DRIVER_NAME
i965
$ echo $DRI_PRIME
1
this configuration I had some problems with firefox lags and kernel panic because of amdgpu driver. Now it is gone too, I think. But this is another problem with amdgpu driver and wayland session.
Now I can run both configurations with no issues, but I have to use X11 server for that. That is not perfect but it'll do for now.
Kernel 4.14 promises a bunch of gpu drivers updates and I think I'll hang with X11 till then or till next gnome-wayland update.
Do I need to mark this thread as [SOLVED]? The issue is still there for people who uses Arch just with wayland and it is not actually solved for me too

maybe adding WorkedAround would be suitable ?
