[Live-devel] Streaming aac audio and h264 video error

[Francesco, Cuzzocrea]

Hi to all
my target is to use the live555 library in order to stream live audio 
and video
source.  Video is in h264 format, while audio is in aac format. I found 
some
similar questions but none of them exaustive.
As first step I downloaded and compiled all libraries and test program, 
all was ok.
Then I used the mediaServer example in order to stream files and all is 
ok too.
After this step I attempt to stream only video; so I created a subclass of
OnDemandServerMediaSubsession that I named myLiveServerMediaSession 
:public OnDemandServerMediaSubsession.
In this class I created a  subclass of FramedSource 
(LiveSourceWithmyData :public FramedSource)
  and created an H264VideoRTPSink. All works fine and I can stream my 
video successfully.
  Now I'm working in order to stream audio too, but I am facing a lot of 
troubles.
  In first step I used two files; an h264 one and an aac one (one for 
audio and
  one for video). Then I modified the

  ServerMediaSession* createNewSMS(UsageEnvironment& env,char const* 
fileName, FILE* fid);

  adding this simple code:

    if (strcmp(extension, ".strm") == 0) {
       // Assumed to be an AAC Audio (ADTS format) file:
       NEW_SMS("Live custom Stream");
       OutPacketBuffer::maxSize = 100000; // allow for some possibly 
large VP8 or VP9 frames
sms->addSubsession(H264VideoFileServerMediaSubsession::createNew(env, 
"myvideostream.264", false));
sms->addSubsession(ADTSAudioFileServerMediaSubsession::createNew(env, 
"reality.aac", reuseSource));
   }else if ......

  that is I added two subsession, one for video and one for audio, but 
it doesn't
  work. Using  vlc I stream only the first session; in this case the 
video one. If
  I revert the two lines :

    if (strcmp(extension, ".strm") == 0) {
       // Assumed to be an AAC Audio (ADTS format) file:
       NEW_SMS("Live custom Stream");
       OutPacketBuffer::maxSize = 100000; // allow for some possibly 
large VP8 or VP9 frames
sms->addSubsession(ADTSAudioFileServerMediaSubsession::createNew(env, 
"reality.aac", reuseSource));
sms->addSubsession(H264VideoFileServerMediaSubsession::createNew(env, 
"myvideostream.264", false));
   }else if ......

  I listen only the audio.  What I missed ?
