## module

### libmetartccore7(pure C)
Implementation of webRTC protocol stack    
AEC/ANS/AGC and other audio and video processing libraries
### libmetartc7(C++)
Realize audio and video collection, encoding, decoding, transmission, rendering, and push-pull streaming  

## Dependencies
To compile libmetartccore7, you'll need to satisfy the following dependencies:  
[OpenSSL](https://www.openssl.org/) or [Mbedtls](https://github.com/Mbed-TLS/mbedtls)  
[libsrtp](https://github.com/cisco/libsrtp)  
[usrsctp](https://github.com/sctplab/usrsctp)  

## Peer connect demo

	int32_t err = Yang_Ok;
	char* localSdp=NULL;
	char* remoteSdp=NULL;
	yangbool enableWhipWhep = yangtrue; 
	YangRtcDirection direction = YangSendonly;//YangSendrecv,YangSendonly,YangRecvonly
	YangPeerConnection *peer = (YangPeerConnection*)yang_calloc(sizeof(YangPeerConnection),1);
	yang_create_peerConnection(peer);
	peer->addAudioTrack(&peer->peer,Yang_AED_OPUS);
	peer->addVideoTrack(&peer->peer,Yang_VED_H264);
	peer->addTransceiver(&peer->peer,direction);
	//sfu server
	if(enableWhipWhep)
	     err = peer->connectWhipWhepServer(&peer->peer,url);
	else
	     err = peer->connectSfuServer(&peer->peer);
	//p2p
	peer->createDataChannel(&peer->peer);//add datachannel
	if((err=peer->createOffer(&peer->peer, &localSdp))!=Yang_Ok){
	    yang_error("createOffer fail!");
	    goto cleanup;
	}
	if((err=peer->setLocalDescription(&peer->peer, localSdp))!=Yang_Ok){
	    yang_error("setLocalDescription fail!");
	    goto cleanup;
	}
	......
	//get remote peer sdp
	if((err=peer->setRemoteDescription(&peer->peer,remoteSdp))!=Yang_Ok){
	    yang_error("setRemoteDescription fail!");
	    goto cleanup;
	}
