Hi,

well, with so little information, all I can ask is: are you sure you
had Wayland-enabled version of a player, and the player is using GLESv2
instead of anything else like desktop OpenGL?

Also, does weston-simple-egl work? If that doesn't work, then nothing
else EGL/Wayland will, and there is still something wrong with the EGL,
driver, or Weston installation or such.

I don't really know in what state the Mesa vc4 is in terms of running
apps, but I do know that in the past, Tomeu's branch did allow
weston-simple-egl to run. Not smoothly and reliably as we had some
open issues, but it did run.

I'm not sure what you are looking for even exists, if XBMC is not
suitable (I mean any of the popular rpi media apps, I don't really
know those either).


Thanks,
pq
