2014-12-11 关于帧率修改的修正:

上面的帧率只是在帧率为0的情况下的默认值,后面会被同文件下的里一个函数重新复制修改unsigned H264or5VideoStreamParser::parse() 这个解析函数有如下修改:

else if (isSPS(nal_unit_type)) { // Sequence parameter set
// First, save a copy of this NAL unit, in case the downstream object wants to see it:
usingSource()->saveCopyOfSPS(fStartOfFrame + fOutputStartCodeSize, curFrameSize() - fOutputStartCodeSize);

if (fParsedFrameRate == 0.0) {
// We haven't yet parsed a frame rate from the stream.
// So parse this NAL unit to check whether frame rate information is present:
unsigned num_units_in_tick, time_scale;
analyze_seq_parameter_set_data(num_units_in_tick, time_scale);
if (time_scale > 0 && num_units_in_tick > 0) {
usingSource()->fFrameRate = fParsedFrameRate = 25;//2*time_scale/(2.0*num_units_in_tick);//这里才是真正的产生作用的地方!

 

修改最大发送帧大小:

DynamicRTSPServer.cpp

OutPacketBuffer::maxSize = 250000;
