Static kVTVideoDecoderSpecification_EnableHardwareAcceleratedVideoDecoder 

pub unsafe static kVTVideoDecoderSpecification_EnableHardwareAcceleratedVideoDecoder: &'static CFString

Available on crate feature VTDecompressionProperties only.

If set to kCFBooleanTrue, the VideoToolbox will use a hardware accelerated video decoder if available. If set to kCFBooleanFalse, hardware decode will never be used.

This key is set in the decoderSpecification passed in to VTDecompressionSessionCreate. Set it to kCFBooleanTrue to allow hardware accelerated decode. To prevent hardware decode, this property can be set to kCFBooleanFalse. In MacOS 10.15 and later, hardware decode is enabled in VTDecompressionSessions by default.
