layers for nodes? can i adress or change layer-level on raspberry-pi ? about info-beamer HOT 4 OPEN

If you use the normal way of playing video you don't need layers. The videos are rendered all within the same OpenGL layer. The order in which you :draw() them determines which video is drawn over each other.

Normally everything is inside a single OpenGL dispmanx (https://info-beamer.com/blog/raspberry-pi-hardware-video-scaler) layer. If you need better video performance it's possible to render videos outside of OpenGL. By default everything is in a single layer.

can i change the order (means layer up/down) while playing a video?
or do i have to stop/start the videop programmatically to push it on another Layer/level to move it in front or back..?
(my idea is to play with transparancey and layer/level overblending..)

As I said: There are no layers. Just draw video2 above video1, if you want video2 to be in front of video1. Reverse the draw order if you want video1 to be in front.
