metaRTC将支持RTMP/SRT/QUIC/RTSP/GB2811等多个协议

概述

行业应用多是集成业务，需要集成多种设备多种协议，metaRTC3.0将助力行业应用实现一类库支持WEBRTC/RTMP/RTSP/GB2811/SRT/QUIC等多种协议，降低行业应用中流媒体的复杂性。

源代码

初始化代码

//YangContext *m_context;
//YangStreamConfig 设置
YangStreamConfig streamConf;
streamConf.streamOptType=Yang_Stream_Publish;//Yang_Stream_Play
strcpy(streamConf.app,app.c_str());
strcpy(streamConf.serverIp,server.c_str());
streamConf.serverPort=pport;

strcpy(streamConf.stream,stream.c_str());
streamConf.uid=0;//0 singleuser 1 multiuser
memset(streamConf.localIp,0,sizeof(streamConf.localIp));
strcpy(streamConf.localIp,localIp.c_str());
streamConf.localPort=localPort;
.....
//建立流协议处理
YangStreamHandle* sh=(YangStreamHandle*)calloc(sizeof(YangStreamHandle),1);
//Yang_Webrtc Yang_Rtmp Yang_Srt	
int32_t nettype=Yang_Webrtc;		
//YangContext* m_context
yang_create_streamHandle(nettype,sh,0,&m_context->avinfo,&m_context->stream,NULL);
sh->init(sh->context,&streamConf);

数据回调函数

void g_playrecv_receiveAudio(void* user,YangFrame *audioFrame){
	if(user==NULL) return;
	YangPlayReceive* rtcHandle=(YangPlayReceive*)user;
	rtcHandle->receiveAudio(audioFrame);
}
void g_playrecv_receiveVideo(void* user,YangFrame *videoFrame){
	if(user==NULL) return;
	YangPlayReceive* rtcHandle=(YangPlayReceive*)user;
	rtcHandle->receiveVideo(videoFrame);
}

//设置YangReceiveCallback m_recvCallback;
	m_recvCallback.receiveAudio=g_playrecv_receiveAudio;
	m_recvCallback.receiveVideo=g_playrecv_receiveVideo;
	m_recvCallback.context=this;
......
streamConf.streamOptType = Yang_Stream_Play;
YangStreamHandle* sh=(YangStreamHandle*)calloc(sizeof(YangStreamHandle),1);
int32_t nettype=Yang_Webrtc;
yang_create_streamHandle(nettype,sh,m_context->avinfo,&m_context->stream,&m_recvCallback);

删除代码

   if(m_recv) m_recv->disConnectServer(m_recv->context);
	yang_destroy_streamHandle(m_recv);
	yang_free(m_recv);

扩展协议支持

//既可以用纯C实现也可以用C++实现
//这是srt例子 
//实现yang_create_stream_srt和yang_destroy_stream_srt
//实现函数connectServer/disConnectServer 等
