struct RtpProfile

struct RtpProfile {

	char *name;
	PayloadType *payload[127];
};

av_profile

extern RtpProfile av_profile;

rtp_profile_get_name()

#define rtp_profile_get_name(profile) 	(profile)->name

rtp_profile_set_name()

#define rtp_profile_set_name(profile,nm) 	(profile)->name=(nm)

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

rtp_profile_set_payload()

#define rtp_profile_set_payload(profile,index,pt)  (profile)->payload[(index)]=(pt)

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

rtp_profile_get_payload()

#define rtp_profile_get_payload(profile,index)	((profile)->payload[(index)])

Gets the payload description of the payload type index in the profile profile.

rtp_profile_clear_payload()

#define rtp_profile_clear_payload(profile,index)	(profile)->payload[(index)]=NULL

Set payload type number index unassigned in profile profile.

rtp_profile_clear_all()

#define rtp_profile_clear_all(profile)	memset((void*)(profile),0,sizeof(RtpProfile))

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