Hello Ross, 

Yes, that was the case, now it works, thank you for your help.
I will continue with this, still we have opened question with metadata streaming.

Your "H264ServerMediaSubsession::createNewStreamSource()” function needs to create a *new* “H264FramedSource” object each time it’s called.  You can’t create just one of those objects in advance, and try to reuse it.  So this code is wrong:

> H264ServerMediaSubsession::H264ServerMediaSubsession(UsageEnvironment& env, Boolean reuseFirstSource) :
>    OnDemandServerMediaSubsession(env, reuseFirstSource) {
>    mFramedSource = H264FramedSource::createNew(env); }
>
> H264ServerMediaSubsession::~H264ServerMediaSubsession() {
>    Medium::close(mFramedSource);
> }
>
> FramedSource* H264ServerMediaSubsession::createNewStreamSource(unsigned /*clientSessionId*/, unsigned& estBitrate) {
>    estBitrate = 500; // kbps, estimate
>
>    // Create a framer for the Video Elementary Stream:
>    return H264VideoStreamDiscreteFramer::createNew(envir(), 
> mFramedSource); }


You should not be creating (or destroying) “H264FramedSource” objects in your “H264ServerMediaSubsession” constructor (or destructor).  Instead, you create a "H264FramedSource” object in your "H264ServerMediaSubsession::createNewStreamSource()” function.  (It will get destroyed automatically when it’s no longer needed.)
