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: https://trac.videolan.org/vlc/ticket/21194
(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.
