Inherits from AVAssetReaderTrackOutput
Declared in AVAssetReaderHapTrackOutput.h


This subclass of AVAssetReaderTrackOutput works just like its super- you call “copyNextSampleBuffer” on it, and it returns a CMSampleBufferRef made with a CVPixelBufferRef containing RGBA/BGRA image data. The class itself is basically a convenience- it simply uses an AVPlayerItemHapDXTOutput to decode and retrieve data, and as such is relatively lightweight.
