C++ (Cpp) get_codec_bitrate Examples

Example #1

File: misc.c Project: AirDev/linphone-android

static double get_audio_payload_bandwidth(LinphoneCore *lc, const PayloadType *pt){
	double npacket=50;
	double packet_size;
	int bitrate;
	bitrate=get_codec_bitrate(lc,pt);
	packet_size= (((double)bitrate)/(50*8))+UDP_HDR_SZ+RTP_HDR_SZ+IP4_HDR_SZ;
	return packet_size*8.0*npacket;
}

Example #2

File: misc.c Project: korobool/liblinphone

 *((codec-birate*ptime/8) + RTP header + UDP header + IP header)*8/ptime;
 *ptime=1/npacket
 */
