<DIV>Hi Engin,<BR>I have got your codes and read them. When I compiled them into the LIVE555 library, I found the codes had some bugs and small flaws and they caused some warnings and errors. I made some changes to satisfy the compiler. In the client, I used VLC to receive and play the .264 file. The VLC worked well except that the pictures seemed not so consecutive. I do not know the reason.<BR></DIV>
<DIV>Some changes are listed below:</DIV>
<DIV> </DIV>
<DIV>1) In H264RTPStreamerFramer.cpp, I think the funtion "timeval* incrementTimeval(timeval* tv, unsigned int duration)" should be written as follows:</DIV>
<DIV>timeval* incrementTimeval(timeval* tv, unsigned int duration)<BR> { <BR> tv->tv_usec+=duration;<BR> if( tv->tv_usec > 1000000)<BR> {<BR> tv->tv_sec=tv->tv_sec+tv->tv_usec/1000000;<BR> tv->tv_usec=tv->tv_usec%1000000;<BR> }<BR> return tv; <BR>}</DIV>
<DIV>Maybe I missed something?</DIV>
<DIV> </DIV>
<DIV>Also, in function "void H264RTPStreamFramer::afterGettingNALU1()", I commented the <BR>"int tmp32" and "short tmp16" to avoid compling warnings because currently they are not used.</DIV>
<DIV> </DIV>
<DIV>Onece again, to avoid compling warning , in function "void encode()", for( int index=0; index<in_size; index+=3), the variable index had better be declared as "unsinged int",<BR>because the in_size is of this type</DIV>
<DIV> </DIV>
<DIV>2) In H264VideoFileServerMediaSubsession.cpp, I added the following:<BR>#include "ByteStreamFileSource.hh", otherwise it has a compling error. This is because <BR>when you create a video source ,you used this class, see follows:<BR>////////////////////////////////////////////////////////////////////////////////////////<BR> // Create the video source:<BR> ByteStreamFileSource* fileSource<BR> = ByteStreamFileSource::createNew(envir(), fFileName);<BR>//////////////////////////////////////////////////////////////////////////////////////// </DIV>
<DIV> </DIV>
<DIV>3) In the H264VideoRTPSink.hh, class H264VideoRTPSink has a member variable fOurFramer (H264VideoStreamFramer *fOurFramer;) and in the H264VideoRTPSink.cpp, it is used to do the following:<BR> char *sps = fOurFramer->getSPS();<BR> char *pps = fOurFramer->getPPS();<BR> unsigned int profile_level_id = fOurFramer->getProfileLevelID();<BR>but class H264VideoStreamFramer does not has these member functions and when compiled it, there were some errors. H264RTPStreamFramer, derived from H264VideoStreamFramer, has these functions. So in H264VideoStreamFramer.hh I added the corresponding virtual functions to make complier satisfactory:<BR> virtual char* getSPS() = 0; //weiyutao added<BR> virtual char* getPPS() = 0; //weiyutao added<BR> virtual unsigned int getProfileLevelID() = 0; //weiyutao added</DIV>
<DIV><BR> </DIV>
<DIV>If you changed the codes or added some new features/functions, please inform me, OK?<BR>I will study the codes more carefully and do more work.<BR>Thanks in advance.</DIV>
