[SOLVED] vlc + Intel/ATI PRIME issue

Hello everyone!
Yesterday I've noticed that if I run vlc with DRI_PRIME=1 var and open some video file to see it vlc immediately crashes with segfault. Here is the output of vlc:

[viktor ~]$ DRI_PRIME=1 vlc
VLC media player 2.2.1 Terry Pratchett (Weatherwax) (revision 2.2.1-0-ga425c42)
[0000000001e02158] core libvlc: Запуск vlc с интерфейсом по умолчанию. Используйте 'cvlc' для запуска vlc без интерфейса.
libva info: VA-API version 0.38.0
libva info: va_getDriverName() returns 0
libva info: Trying to open /usr/lib/dri/i965_drv_video.so
libva info: Found init function __vaDriverInit_0_38
libva info: va_openDriver() returns 0
[00007f5bdda0ea38] avcodec decoder: Using Intel i965 driver for Intel(R) Sandybridge Mobile - 1.6.1 for hardware decoding.
Ошибка сегментирования (core dumped)

Running vlc without DRI_PRIME variable seems glad to me. Also running Quake III Arena, glxgears or glxinfo with DRI_PRIME=1 is perfect.

My OS is x86_64 Arch Linux with kernel 4.2.3-1, vlc is 2.2.1-8 with enabled VA-API video decoder via DRM, LibVA is also installed (libva 1.6.1-1, libva-intel-driver 1.6.1-1, libva-vdpau-driver 0.7.4-2), ATI driver is xf86-video-ati 1:7.5.0-2, Intel video driver is xf86-video-intel 1:2.99.917+478+gdf72bc5-2 and mesa is 11.0.3-1

Any help is appreciated!

Re: [SOLVED] vlc + Intel/ATI PRIME issue

Use vdpau for Radeon, not va-api (package mesa-vdpau). Also, you first need to export the driver, export VDPAU_DRIVER=radeonsi, otherwise it will tr to run it with Intel accel on Radeon card when you start it with DRI_PRIME.

Re: [SOLVED] vlc + Intel/ATI PRIME issue

Hmm. lspci gives:

01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Robson CE [Radeon HD 6370M/7370M] (rev ff)

I've tried this with VDPAU decoder enabled in vlc:

export VDPAU_DRIVER=r600
DRI_PRIME=1 vlc

Now I'm observing no segfault and even can hear sound but I've no video - just black screen. Using radeonsi is also leads to the same results
Also in output I see a lot of erorr messages:

vdpau_display vout display error: presentation queue display failure: An invalid handle value was provided. Either the handle does not exist at all, or refers to an object of an incorrect type.

Re: [SOLVED] vlc + Intel/ATI PRIME issue

Have you tried with different video? Free drivers generally have a lacking hardware acceleration, where one codec works, other won't.

What does DRI_PRIME=1 vdpauinfo say?

Should note that I gave up on both vdpau and vaapi, and am using opengl ouptut on Intel IGP, simply because neither of the two seems to be in a state where you can count on it to work.

After several reloading of .avi video files in vlc all seems good but when I'm scrolling a .mov file video file audio or video randomly stops. I'm finally stuck... I think that I will use Intel IGP with VA-API decoding method because it looks the most stable and bugless.

Should note that I gave up on both vdpau and vaapi, and am using opengl ouptut on Intel IGP...

How can I enable OpenGL output in vlc? Currently I'm using VA-API via DRM video decoding on Intel IGP and I see no option to choose OpenGL in vlc...

Re: [SOLVED] vlc + Intel/ATI PRIME issue

You don't select vaapi output at all, instead you select opengl.
(I'm using mplayer/mpv, by the way, not sure how vlc behaves lately)

oh, thank you! I've used to search it on the Codecs tab.
