You could look into https://github.com/mittorn/a10disp and simply do a
./a10disp displayoff
./a10disp enablehdmi <your_hdmi_mode>
and check if it works.
If so, you can either execute some batch script after you finished
displaying or put the ioctls into your player's source code.
libvdpau-sunxi for example. It'd be ugly, but maybe a workaround.
Remember, i have not tried that by myself :)

Hi Andreas,
Ok, in case that would be the workaround, do you think trying to
compile a simple program that does exactly that could be a solution to
refresh a screen after such a behaviour?
Not having experience, I'd try it if that could be a possible solution
(even if I've no idea where to start :) )
Thank you again,
Simon

Hi Simon,
i only think, that Allwinner already did a workaround against that
non-screen-clearing issue in their in code.
They do DISP_CMD_HDMI_OFF, DISP_CMD_HDMI_SET_MODE and
DISP_CMD_HDMI_ON after finishing displaying on the framebuffer.
They "reset" the HDMI.
I haven't tested that. So that is just a guess and maybe a hint,
where to look for...
Regards
Andreas
