Crate smpte2022_1_packet

Zero-copy access to the header fields of packets formatted according to SMPTE 2022-1, also know as ‘Pro MPEG FEC’ or ‘1D/2D parity FEC’.

Note this does not implement FEC encoding or decoding, just the parsing of the packet header fields. For a decoder, see the smpte2022-1-fec crate.
