windows 调试rtmp协议遇到wireshark抓包出现unknown或send时遇到10054问题之解决方法

一、解决办法：

将chunksize 设置大一点，可以设置为10 * 1024 * 1024

二、通过协议设置

bool GetChunkSize(long nChunkStreamID, long nChunkDataSize, unsigned char* pOut, long& nOut)
{
#define CHUNK_BODY_SIZE			4
#define CHUNK_ARRAY_SIZE		16

	unsigned char btData[CHUNK_ARRAY_SIZE] = { 0 };

	//basic header
	// 0 0 0 0 0 0 1 0   #fmt为0, 可知message header 有11个字节
	btData[0] = nChunkStreamID;

	//时间戳
	btData[1] = 0;
	btData[2] = 0;
	btData[3] = 0;

	//Body占用字节数
	btData[6] = CHUNK_BODY_SIZE & 0xff;
	btData[5] = CHUNK_BODY_SIZE >> 8;
	btData[4] = CHUNK_BODY_SIZE >> 16;

	// Set Chunk Size
	// 通过MessageHeader.h 可知为1时是设置chunk size 大小
	btData[7] = 1;//

	//message stream id
	//message stream id就是指该次媒体流的唯一标识，用于指明属于哪个流，用于区分不同流(NetConnection网络连接流或者是(某个)NetStream网络流)的消息。一个StreamId通常用以完成某些特定的工作. 如使用Id为0的Stream来完成客户端和服务器的连接和控制,用Id为1的Stream来完成Stream的控制和播放等工作.
	btData[8] = 0;
	btData[9] = 0;
	btData[10] = 0;
	btData[11] = 0;

	//body. chunk的大小
	btData[12] = (nChunkDataSize >> 24) & 0xff;
	btData[13] = (nChunkDataSize >> 16) & 0xff;
	btData[14] = (nChunkDataSize >> 8) & 0xff;
	btData[15] = nChunkDataSize & 0xff;

	//------------------------------------------------------------------------------------------
	memcpy(pOut, btData, CHUNK_ARRAY_SIZE);
	nOut = CHUNK_ARRAY_SIZE;
}

调用：

long nLenOfChunkPacket = 0;
	unsigned char btChunkPacket[1024] = { 0 };
	//RTMP Chunk Stream uses message type IDs 1, 2, 3, 5, and 6 for protocol control messages. These messages contain information needed by the RTMP Chunk Stream protocol. These protocol control messages MUST have message stream ID 0 (known as the control stream) and be sent in chunk stream ID 2.
	//RTMP uses message type ID 4 for User Control messages. These messages contain information used by the RTMP streaming layer. Protocol messages with IDs 1, 2, 3, 5, and 6 are used by the RTMP Chunk Stream protocol (Section 5.4). User Control messages SHOULD use message stream ID 0 (known as the control stream) and, when sent over RTMP Chunk Stream, be sent on chunk stream ID 2.
	GetChunkSize(2/*Chunk Stream ID with value 2 is reserved for low-level protocol control messages and commands*/, 10 * 1024 * 1024, btChunkPacket, nLenOfChunkPacket);
    send(socketID, btChunkPacket, nLenOfChunkPacket, 0);
