		void *	payload_ref
	)

Add a process block to an access unit.

An existing NAL unit of type IDR or NON_IDR are required.

If set, payload_ref must be a RefStruct reference backing payload_data. This function creates a new reference to payload_ref in this case. If payload_ref is NULL, the new message will not be reference counted.

		LCEVCRawProcessBlock **	block
	)

Iterate over blocks with the given payload type in an access unit.

Set block to NULL in the first call. Returns 0 while more blocks are available, AVERROR(ENOENT) when all blocks have been found.
