when i played a fairplay streaming by avplayer,calling copyPixelBufferForItemTime on AVPlayerItemVideoOutput the pixelbuffer returns NULL.is there any way to get the pixel buffer from a stream that is protected using FairPlay on iOS or apple's APIs in order to display FairPlay stream on an OpenGL texture in 3D space?
How do I access a FairPlay protected stream's frame in avplayer?
Any luck?
