mpv flatpak falling back to vo: [xv]

[LS650V]

I am guessing the problem is "[vo/gpu/opengl] Suspected software renderer or indirect context."

Is this due to the version of Mesa you are using?

debian's version mpv 0.35.1 works fine on my system.

Have you tried flatpak update to update the gpu drivers?

On my Intel Laptop, the link works wfine.

Graphics drivers are up to date and I am NOT forcing vo=xv. I guess I will stick with debian's older version of mpv which works as expected on my system.

Flatpak uses mesa 24.3.1. This gpu seems to be 16 years old, I'm not sure if it's still supported by latest mesa.

You may install org.freedesktop.Platform.GlxInfo//24.08 app then run

flatpak run --env=LIBGL_DEBUG=verbose org.freedesktop.Platform.GlxInfo

so mesa fallbacks to software rendering. There may be no driver for this gpu

Extended renderer info (GLX_MESA_query_renderer):
    Vendor: Mesa (0xffffffff)
    Device: llvmpipe (LLVM 19.1.5, 128 bits) (0xffffffff)

[CounterPillow]

There is a driver, but it's in Mesa Amber: https://docs.mesa3d.org/amber.html

Mesa was split into two so that the ancient stuff can be separate. I'm not sure if flatpak packages Amber, though it would be nice if it would.

[Erick555]

freedesktop-sdk flatpak runtime doesn't package mesa amber and doesn't plan to do so in the future.

[CounterPillow]

Yes, they left it up to flathub. There really is no reason for flathub not to package it, other than nobody who still needs it wanting to do it I guess.
