Display overlay using DRM/KMS between QT and Video Compositions

[SaurabhShah]

Environment: Atom E3940 with poky linux

In our application, we will be having NVR + NDD functionality where multiple videos are played on screen which are received from RTSP streams. In addition to that one more GUI application built using QT technology will be running on the board. This application will be rendering GUI on the HDMI screen to provide a way to change some system configurations. Is there any reference for how the combined rendering of video compositions & QT application can be made using DRM/KMS module?

We are trying to achieve it using different DRM display planes but we are stuck with how to select different planes for both applications.
