解释代码 void PacketServer::startProcessingPacket() { packet = provider->popPacket(inputGate->getPathStartGate()); take(packet); packet->setArrival(getId(), inputGate->getId(), simTime()); EV_INFO << "Processing packet " << packet->getName() << " started." << endl; }

这是一个C++程序里 PacketServer 类的成员函数 startProcessingPacket 的定义。该函数的作用是从一个 packet provider(数据包提供者)获取一个数据包,然后将其进入 PacketServer 的处理流程。具体的处理逻辑可能在 take() 函数或者其他地方进行。在取到数据包后,该函数会将数据包的到达时间、ID 等信息设置完整,并打印出“Processing packet”及其名称的日志。

picture->pkt_dts = p->avpkt->dts;
This line of code sets the dts (decoding timestamp) value of a picture packet to the dts value of the corresponding AVPacket.
AVPacket is a structure in the FFmpeg library that represents a multimedia packet, containing compressed audio or video data. The dts value in an AVPacket represents the timestamp at which the packet should be decoded and presented to the user.
By setting the pkt_dts value of a picture packet to the dts value of the corresponding AVPacket, this line of code ensures that the picture will be decoded and presented at the correct timestamp, as specified in the multimedia stream.
这事一个信元的项目,涌入释放节点的 if(rphead && ::is_open_reverse) { if(PACKET_NONE != rphead->btCurStaus) { rphead->pktbuf = NULL;//防止重复存包; } rphead->CdrRaw.ncdrid = node->value_.GetCdrid(); rphead->CdrRaw.tstart.tm_cycles = node->value_.GetTstart(); rphead->CdrRaw.cdrstat = PACKET_END; rphead->btCurStaus = PACKET_END; pubSendPkt((void*)rphead); }这段内容是做什么的
这段代码是判断释放节点是否开启了反向链路,并且当前数据包的状态不是 PACKET_NONE,然后将数据包的指针设置为 NULL,将节点 ID 和时间戳写入 CdrRaw 结构体,将数据包状态设置为 PACKET_END,将 btCurStaus 状态也设置为 PACKET_END,最后发送数据包。它可能是一个网络通信中的数据包发送逻辑。
