live555 x264参数修改

以640*480为例

live555/liveMedia/StreamParsercpp.cpp：
define BANK_SIZE 15000 改为：
define BANK_SIZE 3000000

live555/mediaServer/DynamicRTSPServer.cpp：
OutPacketBuffer::maxSize一共有4处全部改为
OutPacketBuffer::maxSize = 2000000;

live555/liveMedia/MediaSink.cpp:
unsigned OutPacketBuffer::maxSize = 60000;改为
unsigned OutPacketBuffer::maxSize = 2000000;

继承framedSource之后

unsigned H264FramedLiveSource::maxFrameSize() const
{
　　return 1024*180;
}

MediaSink.cpp
114行：
unsigned OutPacketBuffer::maxSize = 30000;

StreamParser.cp
宏定义：
#define BANK_SIZE 150000，改为2400000；

MultiFramedRTPSink.cpp
47行:
setPacketSizes(1000, 8192);


RTPInterface.cpp
129行:
increaseSendBufferTo(envir(), fGS->socketNum(), 512*1024);
//数据累积发送，不再单独发送
//注释掉332行，修改为以下:
//if (!sendDataOverTCP(socketNum, framingHeader, 4, False)) break;
//if (!sendDataOverTCP(socketNum, packet, packetSize, True)) break;
struct iovec iov[2];
iov[0].iov_base = framingHeader;
iov[0].iov_len = 4;
iov[1].iov_base = packet;
iov[1].iov_len = packetSize;
writev(socketNum, iov, 2);

帧率改为30，直播延迟就由5延迟慢慢减少到1秒不到，不知道为什么会这样，如果是24帧，直播延迟会越来越大

encoder->x264_parameter->i_fps_num = 30;//码率分子
encoder->x264_parameter->i_fps_den = 1;//码率分母
