I'm using a standard Android implementation of Vuforia (Not unity) and I've been trying to acquire the background video as a texture,
I know about using glReadPixels, however this is only good for taking 'screenshots' as it is extremely slow.
My intention is to send a constant stream of images over the network.
I've looked at the example, but all I see is the pixel being passed into opengl in the background, I don't see any reference of reading the pixels from the video stream.
Can someone point me in the right direction?
