Function Documentation

Compy_RtpHeader_deserialize()

int Compy_RtpHeader_deserialize	(	Compy_RtpHeader *restrict	self,
		const uint8_t *	data,
		size_t	len
	)

Parses an RTP header from a binary buffer.

Fields in self will be in network byte order, matching the convention used by Compy_RtpHeader_serialize.

Parameters

[out]	self	The parsed RTP header.
[in]	data	The buffer to parse from.
[in]	len	The length of data in bytes.

Precondition

self != NULL

data != NULL

Returns

The total header size in bytes on success, or -1 if len is too small or the version field is not 2.

Compy_RtpHeader_serialize()

uint8_t * Compy_RtpHeader_serialize	(	Compy_RtpHeader	self,
		uint8_t	buffer[restrict]
	)

Writes self to buffer.

Parameters

[in]	self	The RTP header to write.
[out]	buffer	The pointer to write to. Must be at least of size Compy_RtpHeader_size(self).

Returns

The pointer to a passed buffer.
