Gstreamer - glimagesink client-draw-callback

spear_kor — Wed, 30 Sep 2020 07:41:18 GMT

Dear All,

I was wondering if there is any available example for client-draw-callback implementation to draw frames using GLES2.

I need to paint the decoded video frames on imx.8 using Yocto.

Hello Spear-kor,

In your yocto BSP you have the graphics examples, that include the triangle as example two, data in the
ESContext structure include information such as the window width and height, EGL context, and callback function pointers.

The rest of the main function is responsible for creating the window, initializing
the draw callback function, and entering the main loop:
esCreateWindow(&esContext, "Hello Triangle", 320, 240,
ES_WINDOW_RGB);
if(!Init(&esContext))
return 0;
esRegisterDrawFunc(&esContext, Draw);
esMainLoop(&esContext);

Regards

Hello,

Thanks for the response.

However, I think I am misunderstood. I was asking for the client-draw-callback signal handler of GStreamer.

Thanks
