LibreElec 9.2 with RPI4 and EGL

Hi Guys

I need to create an overlay on top of Kodi UI using EGL apis.

It works fine on RPI3 using dispmanx apis (EGL on the Raspberry Pi)

But since the RPI4 has upgraded itself to vc6, and does not have support for dispmanx, is there way I can achieve this?

Any help in this direction would be really appreciated.

You have been marked this thread as solved. Is this correct?

Sorry, may be that was by mistake.

Looks like there is a lot of inactivity in this thread.

May be i can add some more info meanwhile.

I understand now that the Kodi is running on GBM/DRM.

I have tried to run a simple kmscube (Projects · Mesa / kmscube · GitLab) application and it fails to run when kodi is running.

Once I kill kodi using (systemctl stop kodi) it runs fine.

So i assume, kodi is the master and I need to somehow request kodi to create the surface or something. Could someone throw some light on this?

Can I make kodi create a new DRM plane and let may app post buffers on that plane? There by i can achieve what i want.
I did try this and it failed on the first try with drmModeSetPlane.

I added a new plane in DRMUtils.cpp in kodi and then used that plane id to call drmModeSetPlane in my app.
Still i guess it has permission issue. How can i avoid this?

Alternative approach is start Xorg server.

I have tried this as well but fails with following error

xorg.service: Failed with result 'protocol'.

Hi

The goal is simple I need to create a overlay on top of kodi UI to show some advertisements when TV streams are being presented.

Not a commercial app at all. Just working on a cool idea. This will be opensourced. I am not working for an org or something.. just a student learning something new. I can create a repo fork and share my updates as well.

ok sounds good. Let me have a look. Thanks
