How mix gstreamer video and cairo graphics on imx8

Hi all,

Env: Linux 5.10, Weston, imx8

We have a C application coming from an imx6 platform that runs gstreamer to display video, and Cairo to display graphics.

Before imx8, it was easy to mix graphics and video together, with frame buffer method.

But now, how to do ? Cairo works fine if used alone, and Gstreamer too. But how mix output of both, properly ?

We've tried Cairooverlay, but it makes program hang, and this stuff seemed to be a bit old, not sure it's still functional.

Rgds,

Christophe
