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