Detailed Description

Reed-Solomon FEC encoder state for video packets.

Member Function Documentation

data()

char * stream::fec::fec_t::data ( size_t el )

inline

Return the FEC shard data pointer for a packet-group element.

Parameters

el	Packet-group element index.

Returns

Pointer to the shard bytes for the requested element.

prefix()

char * stream::fec::fec_t::prefix ( size_t el )

inline

Return the FEC prefix bytes for the current packet group.

Parameters

el	Packet-group element index.

Returns

Pointer to the element's prefix bytes, or nullptr when no prefix is used.

size()

size_t stream::fec::fec_t::size ( ) const

inline

Return the serialized size of the current object.

Returns

Number of elements currently stored.
