> devices under /dev/dri/ are not only used by libva, but also used by other DRI driver, such as opengl, opencl. you should add yourself to the video group if you want to use DRI driver.
So shouldn't this package add users to the video group?
Anyway, adding myself to the video group or setting `chmod og+rw /dev/dri/card0` does not make this issue go away (more details upstream). Something else is wrong here and I don't know what it is. (In reply to Christian Stadelmann from comment #0) > VA error: wayland: failed to identify /dev/dri/card0: Permission denied > (errno 13) > libva error: va_getDriverName() failed with unknown libva > error,driver_name=(null) > libva error: va_getDriverName() failed with unknown libva > error,driver_name=(null) Actually, this output is caused by the video thumbnailer which drops privileges at start and then tries to stat() and open() /dev/dri/card0. I reported it upstream to https://bugzilla.gnome.org/show_bug.cgi?id=783169. This issue is not causing the playback failure. The upstream bug was closed as too many issues were mixed together. (In reply to Paul Menzel from comment #8) > The upstream bug was closed as too many issues were mixed together. There is an upstream tracking bug, I'm referring to that one instead. Okay, are soon as libva is concerned. I confirm that I've managed to use vaapi under f28 wayland (with cvlc, so not using qt gui enforcing x11 on the video pipeline). Can I have any recent reproducer on f28? (or can we close the bug). Thx This message is a reminder that Fedora 26 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '26'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 26 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. It looks like on Fedora 28, adding the current user to the "video" group is not necessary any more. |
Description of problem: When trying to run any libVA based application on wayland, they always fail. Version-Release number of selected component (if applicable): totem-3.24.0-1.fc26.x86_64 gstreamer1-vaapi-1.12.0-1.fc26.x86_64 libva-1.8.2-1.fc26.x86_64 libva-intel-driver-1.8.2-1.fc26.x86_64 How reproducible: always. Ever since I started using wayland (about 2 years ago). Steps to Reproduce: 1. have the packages installed as noted above 2. run a gnome/wayland session 3. start totem 4. play video file Actual results: Green screen, no video output. Output of totem: VA error: wayland: failed to identify /dev/dri/card0: Permission denied (errno 13) libva error: va_getDriverName() failed with unknown libva error,driver_name=(null) libva error: va_getDriverName() failed with unknown libva error,driver_name=(null) Expected results: Work fine Additional info: This renders libva completely useless on wayland. The warning (first line) is printed from drm_handle_device in libva/va/wayland/va_wayland_drm.c. $ ls -al /dev/dri drwxr-xr-x. 3 root root 100 23. Mai 06:53 . drwxr-xr-x. 19 root root 4240 24.
