    Playing local files (OGG and MP4/H.264) works fine if I load them into a Firefox tab, and also works if I run mplayer, but smplayer (which should
    just be mplayer in a wrapper), vlc, mpv, and ffplay all show just a black screen (while successfully playing audio from the files).

    System: current Void
    CPU: 12th Gen Intel(R) Core(TM) i9-12900K
    GPU: AlderLake-S GT1

    The problem may be that the GPU is not being used. I installed
    nvtop, and it always shows GPU usage as zero.

    I have installed these packages: intel-video-accel, mesa-vulkan-intel, xf86-video-intel. Apparently that's not enough.

    I know nothing about Void packages and what's in them, but you want
    VA-API if Intel GPU video decoding is desired. Try installing vainfo
    (from libva) and run it from the command line to see if a VA-API
    driver is installed correctly.

    Although they're for other distros, these links should contain
    relevent info: https://wiki.archlinux.org/title/Hardware_video_acceleration#Configuring_VA-API https://wiki.gentoo.org/wiki/VAAPI

    I think you want the "media" VA-API driver for your GPU
    (installed as iHD_drv_video.so).

    You can also compare video output drivers in mplayer with the "-vo"
    option on the command-line. See "VIDEO OUTPUT DRIVERS (MPLAYER
    ONLY)" in the mplayer(1) man page. One output driver might display
    the same behaviour as VLC etc., and then you can pin down exactly
    which display method has a problem. I'm not sure which if any do
    use VA-API in mplayer though, if that's really the problem.

    If VA-API isn't being used, it must be a problem with the X display
    driver (assuming you're not using Wayland). Check the Xorg log
    file (wherever that is in your distro).

    OK, the manual (https://docs.voidlinux.org/config/graph ... intel.html at the bottom) says:

    For newer Intel chipsets, the DDX drivers may interfere with correct
    operation. This is characterized by graphical acceleration not working and
    general graphical instability. If this is the case, try removing all
    xf86-video-* packages.

    So, I ran

    xbps-remove xf86-video-amdgpu xf86-video-ati xf86-video-dummy xf86-video-fbdev xf86-video-intel xf86-video-nouveau xf86-video-vesa xf86-video-vmware

    The system responds with:

    Code: Select all

    xf86-video-amdgpu-23.0.0_1 in transaction breaks installed pkg `xorg-video-drivers-7.6_23'
    xf86-video-ati-22.0.0_1 in transaction breaks installed pkg `xorg-video-drivers-7.6_23'
    xf86-video-dummy-0.4.1_1 in transaction breaks installed pkg `xorg-video-drivers-7.6_23'
    xf86-video-fbdev-0.5.0_2 in transaction breaks installed pkg `xorg-video-drivers-7.6_23'
    xf86-video-nouveau-1.0.17_2 in transaction breaks installed pkg `xorg-video-drivers-7.6_23'
    xf86-video-vesa-2.6.0_1 in transaction breaks installed pkg `xorg-video-drivers-7.6_23'
    xf86-video-vmware-13.4.0_1 in transaction breaks installed pkg `xorg-video-drivers-7.6_23'

    Suggestions on getting proper video playback and acceleration? I've never had an Intel GPU on Linux before.

    At a suggestion on the Void Forum, I also removed xorg-video-drivers. It worked.
    All is normal now.
