Static kVTCompressionPropertyKey_PixelTransferProperties 

pub unsafe static kVTCompressionPropertyKey_PixelTransferProperties: &'static CFString

Available on crate feature VTCompressionProperties only.

Specifies properties to configure a VTPixelTransferSession used to transfer source frames from the client’s image buffers to the video encoder’s image buffers, if necessary.

Setting this property alone does not necessarily guarantee that a VTPixelTransferSession will be created. See VTPixelTransferProperties.h.
