Yes. It works!! thank you very muchy!! is there a way to change the resolution or stretch the video to fill up the display? I will have a wide screen for this setup.

now I connect the widescreen and I cannot stretch the video to the display size as shown. any idea of how to proceed this?

You will probably need videoscale element before the glupload. It should convert the video to desired size
