Vuforia: it is possible play a Movie texture with alpha in iOS?

Question

I\'m trying to use a video with alpha channel, but all I get is the alpha channel as color black.

I\'m using the Vuforia video playback example.

I hope I\'m not

Answer 1

Vuforia plays video by using the built-in system video players (on iOS and Android) by setting them to output to a render texture.

The system players do not support alpha channel video.

You need to apply a chroma-key shader on the render texture to remove say green or purple.

There is some discussion in the vuforia forums:
