I want to create a AR app with some render engines for iOS.
I have created a render texture in the engine. The texture is to display camera video. But I can not get stream of camera video via QCAR.
I only found a class is named QCAR::Renderer. There is a function QCAR::Renderer::drawVideoBackground ( ).
But I don' t want use this function. But Can I get stream of camera video or byte[].
Thanks,
You need to use SetFrameFormat()

...also, worth searching the forums.

Have a look at the Background Texture Access sample, as this shows how the video feed can be captured withn a texture and manipulated.

Also, a small addtional note to what Nalin says,
keep in mind that the Background Texture Access sample shows the video background texture as a grayscale image because the Shader used performs a grayscale rendering by averaging the R,G,B components of the texture. By modifying the shader code you can alos have normal RGB rendering.
