            Bug ID: 110850
           Summary: Vlc fails to decode video using vaapi
           Product: Mesa
           Version: 19.1
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: akarshanbiswas@fedoraproject.org
        QA Contact: dri-devel@lists.freedesktop.org

Tested Mesa version: 19.1.0 rc4, 19.0.5

Operating System: Fedora 30 with kernel 5.1.6

VLC version: 3.0.7 Vetinari (revision 3.0.6-223-g5fc4822ace)

GPU's tested: Both on Radeon RX550 and AMD APU a9-9410(stoney series)

Testing on both Xorg and Wayland


This bug is present since long time, selecting either vaapi video decoder or
vaapi video decoder via drm in vlc--> toos --> preferences--> Input/Codecs -->
hardware accelerated decoding fails and vlc switches to either vdpau or
software decoding.
(vdpau driver can't decode some hevc videos, vdpau is not supported on wayland)

Steps to reproduce:

1) After selecting vaapi video decoder in vlc, run vlc on a terminal with the
-v flag (for verbose)
2) play any media
3) Check the terminal ( Meanwhile vlc will try to switch to vdpau)



Actual results:
vlc's vaapi decoder fails with:
```
libva info: VA-API version 1.4.1
libva info: va_getDriverName() returns 0
libva info: User requested driver 'radeonsi'
libva info: Trying to open /usr/lib64/dri/radeonsi_drv_video.so
libva info: Found init function __vaDriverInit_1_4
libva info: va_openDriver() returns 0
[00007f4c78001f60] glconv_vaapi_x11 gl error: vaDeriveImage: operation failed
[00007f4c7c062b30] main video output error: video output creation failed
[00007f4c88056060] main decoder error: failed to create video output
```

Expected result:
Vlc should play vaapi as it does in Intel GPUs.



I have a vlc bug ticket which says that the driver is buggy here:

(In reply to Akarshan Biswas from comment #0)

I can confirm a similar issue. In my case, the problem occurs on older Radeon
hardware (HD 3650) which uses the r600 driver. The result is the same, no
hardware acceleration is possible through the integrated unified video decoder
(UVD). CPU has around 100% load.

It seems that the VA-API is broken, at least for certain systems.

Mesa version: 19.0.8

OS: Kubuntu 18.04.3 LTS with kernel 5.0.0-27

Kaffeine: 2.0.18
