avformat_open_input打开不存在的rtsp阻塞 网上很多文章,说到avformat_open_input阻塞,就设置一下 av_dict_set(&avdic,"stimeout ","300000",0); ffmpeg源码rtsp.c有这样一段定义 {"timeout","set maximum timeout (in seconds) to wait for incoming connections (-1 is infinite, imply flag listen)",...
av_dict_set(&optionsDict, "rtsp_transport", "tcp", 0); //采用tcp传输 av_dict_set(&optionsDict, "stimeout", "2000000", 0); //如果没有设置stimeout,那么把ipc网线拔掉,av_read_frame会阻塞(时间单位是微妙) // Open video file if(avformat_open_input(&pFormatCtx, streamurl, NULL, &op...
接着,在request string查找一个"Transport:" header,目的是为了从中提取客户端请求的一些参数(调用parseTransportHeader方法,该方法在RTSPServer类中),如clientsDestinationAddressStr、ClientRTPPortNum等。 再接着是getStreamParameters(该方法在ServerMediaSession类中被定义为纯虚函数并在OnDemandServerMediaSubsession类中...
