3. LIVE555 빌드
1) 빌드는 make 명령으로 간단히 할 수 있다.
busyman@busyman:~/play/bmNVR/lib/LIVE555/live$ make
# 중략
c++ -c -Iinclude -I../UsageEnvironment/include -I../groupsock/include -I/usr/local/include -I. -O2 -DSOCKLEN_T=socklen_t -D_LARGEFILE_SOURCE=1 -D_FILE_OFFSET_BITS=64 -Wall -DBSD=1 BasicUsageEnvironment.cpp

^~~~

busyman@busyman:~/play/bmNVR/lib/LIVE555/live$
2) 그런데 빌드 실패, 해결 방법은 여러 가지 겠지만 일단 아래와 같이 config.linux 수정한다. 만약 다른 에러가 발생했다면 구글 검색을 통해 해결해 보자.
- COMPILE_OPTS 에 "-DNO_STD_LIB" 추가
busyman@busyman:~/play/bmNVR/lib/LIVE555/live$ cat config.linux

4. LIVE555 테스트
빌드가 되었으니 잘되었는지 확인해 보자. LIVE555는 testProgs 하위에 여러 가지 예제를 제공하는데 우리는 NVR 제작이 목적이므로 testRTSPClient로 테스트한다. 빌드는 되었지만 라이브러리 호환으로 인해 실행이 안될 수 있으니 일단, 실행해 보자.
busyman@busyman:~/play/bmNVR/lib/LIVE555/live/testProgs$ ./testRTSPClient
Usage: ./testRTSPClient <rtsp-url-1> ... <rtsp-url-N>
(where each <rtsp-url-i> is a "rtsp://" URL)
1) rtsp 서버 준비
rtsp 서버를 준비하는 것도 귀찮은 일이다. IP CAM이 있다면 가장 편한 방법이고 없다면 VLC가 그나마 쉬운 방법이다.
2) testRTSPClient 실행
- rtsp 서버가 준비되었다면 서버를 시작하고 testRTSPClient를 실행해 보자.
- 정상 동작이 되었다면 아래와 같이 스트림에 대한 정보가 표시되고 수신된 데이터 정보가 표시된다. rtsp에 사용한 영상이 video만 있어 video/H264 만 표시된다.
busyman@busyman:~/play/bmNVR/lib/LIVE555/live/testProgs$ ./testRTSPClient rtsp://127.0.0.1:8554/test

3) 테스트 프로그램을 약간 수정해 보자. 아래와 같이 수신한 데이터의 첫 4byte를 출력해 보면 NAL packet 단위로 수신되는 것을 확인할 수 있다. 188byte 단위로 전송되지만 LIVE555에서 frame 단위로 만들어 줌으로써 뒷 단 처리의 수고를 덜 수 있다.
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 uHexDump[(4*4)+1];
sprintf(uHexDump, "[%02X][%02X][%02X][%02X]", fReceiveBuffer[0], fReceiveBuffer[1], fReceiveBuffer[2], fReceiveBuffer[3]);
envir() << ".\t" << uHexDump;
char uSecsStr[6+1]; // used to output the 'microseconds' part of the presentation time
sprintf(uSecsStr, "%06u", (unsigned)presentationTime.tv_usec);
envir() << "\tPresentation time: " << (int)presentationTime.tv_sec << "." << uSecsStr;
if (fSubsession.rtpSource() != NULL && !fSubsession.rtpSource()->hasBeenSynchronizedUsingRTCP()) {

}

#endif
