mpv cannot open video_output device

Since today, I can’t play video with mpv anymore. Yesterday everything worked fine, but I couldn’t figure if an update was responsible for that.
I’m using a wayland-only session, I’ve disabled x11 applications.
My graphic card is an intel one (I don’t know which one exactly however).
Installing `vulkan-intel` solves the problem, but I’m not comfortable with using vulkan, as I don’t know what it is, and I didn’t need it until now. Moreover, using it mpv says :

INTEL-MESA: warning: Ivy Bridge Vulkan support is incomplete
INTEL-MESA: warning: ../mesa-19.2.0/src/intel/vulkan/genX_cmd_buffer.c:5075: FINISHME: Implement events on gen7

The relevant log informations are :

I would think that I need to activate DRM EGL backend but I couldn’t figure out what it was or how to do that.
Any help ?

Re: mpv cannot open video_output device

Well something has changed between "yesterday" and "today". Did you run an update or not? If so it would be relatively trivial to check which packages where updated and might be responsible here. 

lscpi

will tell you which GPU you have.

Re: mpv cannot open video_output device

I did run an update, however I took a quick look at the list of updated packages since 2 days and I did not see anything that seemed related to my problem.
I update regularly (daily basis) core, extra, community and multilib.
`mpv -vo drm favporn.pm4` yields:

[vo/drm] VT_GETMODE failed: Inappropriate ioctl for device
[vo/drm] Failed to set up VT switcher. Terminal switching will be unavailable.
[vo/drm/kms] Connector 67 currently connected to encoder 68
[vo/drm/kms] Selected Encoder 68 with CRTC 42
[vo/drm] DRM Atomic support found
[vo/drm/kms] Using default plane 31 for OSD
[vo/drm/kms] Using default plane 34 for video
[vo/drm] Cannot set CRTC: Permission denied

and fails to start the video.
`lspci` yields:

and if I’m not mistaken,

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)

is my graphic card (but this doesn’t mean much to me).

Re: mpv cannot open video_output device

I did not see anything that seemed related to my problem

Actual log?

[vo/drm] Cannot set CRTC: Permission denied

What's the output of 

loginctl session-status

?

Re: mpv cannot open video_output device

Uhm, I didn’t know pacman logged every action it did, good to know. I found then where the problem came from: I upgraded… mpv yesterday! That explains it. I downgraded it and my video played fine. I also found out why the upgrade caused a bug: mpv no longer has the gpu-context wayland:

$ mpv --version # Last mpv version

Yup, looks like a rebuild error (there's nothing in the "update" that would explain a behavioral change - just an additional dep on mujs)
