VIDEO in C# : play in background input video card in a winform

[yfbf]

Hi,

I am looking for playing the input video card in background of my winform.

- I want to select wich input I want to display in my winform;
- I want to add in foreground some control panels (transparent) wich each have a functionality.

=> I find many projects for display the video in the background but when I insert a control panel, button, ... I can't see the control.


example :

I connect to my input card a video splitter wich have 4 pictures.

For each picture, I would like to have one control panel.
And for each control panel, I want to have a special functionality.
The control pane must to be transparent color with a colour in the border.

If anyone can help me it is great.

Best Regards,
