參考自網絡，自己測試通過。特記錄如下：
使用live555 客戶端 testRTSPClient.cpp修改如下：
void DummySink::afterGettingFrame(unsigned frameSize, unsigned numTruncatedBytes,
struct timeval presentationTime, unsigned /durationInMicroseconds/) {
// We’ve just received a frame of data. (Optionally) print out information about it:
#ifdef DEBUG_PRINT_EACH_RECEIVED_FRAME
if (fStreamId != NULL) envir() << "Stream “” << fStreamId << “”; “;
envir() << fSubsession.mediumName() << “/” << fSubsession.codecName() << “:\tReceived " << frameSize << " bytes”;
if (numTruncatedBytes > 0) envir() << " (with " << numTruncatedBytes << " bytes truncated)”;
char uSecsStr[6+1]; // used to output the ‘microseconds’ part of the presentation time
sprintf(uSecsStr, “%06u”, (unsigned)presentationTime.tv_usec);
envir() << ".\tPresentation time: " << (unsigned)presentationTime.tv_sec << “.” << uSecsStr;
if (fSubsession.rtpSource() != NULL && !fSubsession.rtpSource()->hasBeenSynchronizedUsingRTCP()) {
envir() << “!”; // mark the debugging output to indicate that this presentation time is not RTCP-synchronized
}
envir() << “\n”;
#endif
//todo one frame
//save to file
if(!strcmp(fSubsession.mediumName(), “video”))
{
if(firstFrame)
{
unsigned int num;
SPropRecord *sps = parseSPropParameterSets(fSubsession.fmtp_spropparametersets(), num);
// For H.264 video stream, we use a special sink that insert start_codes:
struct timeval tv= {0,0};
unsigned char start_code[4] = {0x00, 0x00, 0x00, 0x01};
FILE *fp = fopen(“test.264”, “a+b”);
if(fp)
{
fwrite(start_code, 4, 1, fp);
fwrite(sps[0].sPropBytes, sps[0].sPropLength, 1, fp);
fwrite(start_code, 4, 1, fp);
fwrite(sps[1].sPropBytes, sps[1].sPropLength, 1, fp);
fclose(fp);
fp = NULL;
}
delete [] sps;
firstFrame = False;
}
char *pbuf = (char *)fReceiveBuffer;
char head[4] = {0x00, 0x00, 0x00, 0x01};
FILE *fp = fopen(“test.264”, “a+b”);
if(fp)
{
fwrite(head, 4, 1, fp);
fwrite(fReceiveBuffer, frameSize, 1, fp);
fclose(fp);
fp = NULL;
}
}
// Then continue, to request the next frame of data:
continuePlaying();
}
