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.

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.
