Static kVTDecompressionPropertyKey_RequestRAWOutput 

pub unsafe static kVTDecompressionPropertyKey_RequestRAWOutput: &'static CFString

Available on crate feature VTDecompressionProperties only.

For decoders which produce RAW output, this property requests that the VTDecompressionSession provide output which has not been processed.

When a decoder produces RAW output (signalled by kVTDecompressionPropertyKey_DecoderProducesRAWOutput) the VTDecompressionSession will automatically invoke a VTRAWProcessingSession with default settings and emit processed frames by default, or when kVTDecompressionPropertyKey_RequestRAWOutput is set to kCFBooleanFalse. If a client wants to run a VTRAWProcessingSession on the RAW output themselves in order to control the post-decode processing of the decoded CVPixelBuffers, they must set kVTDecompressionPropertyKey_RequestRAWOutput to kCFBooleanTrue. If kVTDecompressionPropertyKey_RequestRAWOutput has been enabled and the decoder produces RAW output, the VTDecompressionSession will return CVPixelBuffers in the decoder’s native RAW format. Any destinationImageBufferAttributes set on the VTDecompressionSession will be ignored.
