Detailed Description

Using and creating standart and custom RTP profiles.

Define Documentation

#define rtp_profile_clear_payload	(	profile,
		index
	)	rtp_profile_set_payload(profile,index,NULL)

Set payload type number unassigned in the profile.

Parameters:

profile	an RTP profile
index	the payload type number

Function Documentation

bool_t fmtp_get_value	(	const char *	fmtp,
		const char *	param_name,
		char *	result,
		size_t	result_len
	)

Parses a fmtp string such as "profile=0;level=10", finds the value matching parameter param_name, and writes it into result. Despite fmtp strings are not used anywhere within oRTP, this function can be useful for people using RTP streams described from SDP.

Parameters:

fmtp	the fmtp line (format parameters)
param_name	the parameter to search for
result	the value given for the parameter (if found)
result_len	the size allocated to hold the result string

Returns:: TRUE if the parameter was found, else FALSE.

void payload_type_destroy ( PayloadType * pt )

Frees a PayloadType.

References _PayloadType::mime_type.

void payload_type_set_recv_fmtp	(	PayloadType *	pt,
		const char *	fmtp
	)

Sets a recv parameters (fmtp) for the PayloadType. This method is provided for applications using RTP with SDP, but actually the ftmp information is not used for RTP processing.

void payload_type_set_send_fmtp	(	PayloadType *	pt,
		const char *	fmtp
	)

Sets a send parameters (fmtp) for the PayloadType. This method is provided for applications using RTP with SDP, but actually the ftmp information is not used for RTP processing.

void rtp_profile_clear_all ( RtpProfile * obj )

Initialize the profile to the empty profile (all payload type are unassigned).

Parameters:

profile a RTP profile

void rtp_profile_set_name	(	RtpProfile *	obj,
		const char *	name
	)

Set a name to the rtp profile. (This is not required)

Parameters:

profile	a rtp profile object
nm	a string

void rtp_profile_set_payload	(	RtpProfile *	prof,
		int	idx,
		PayloadType *	pt
	)

Assign payload type number index to payload type desribed in pt for the RTP profile profile.

Parameters:

profile	a RTP profile
idx	the payload type number
pt	the payload type description
