[Live-devel] FrameSource:Getnextframe error while streamingPCMframes

[Krishna]

Hi Ross,

I have attached 
1. my Device source file Wavsource.cpp 
2. WaveStreamer .cpp( took a reference from testWavAudioStreamer.cpp) where I have thread to read the samples and have code for initialization and starting the session.

Regards

  I found the problem that uLawFromPCMAudioSource  afterGettingFrame is not getting called when I use DeviceSource based design and triggering concept.
  i.e. 
  If I am calling FramedSource::afterGetting(this) in doGetNextFrame itself , it is calling afterGettingFrame  function in uLawFromPCMAudioSource   followed by calling afterGettingFrame   function in MultiFramedRTPSink.

  If I am calling FramedSource::afterGetting(this) in deliverFrame(which will called by trigger event), then it is calling only afterGettingFrame   function in MultiFramedRTPSink and not uLawFromPCMAudioSource   afterGettingFrame  function.
  That's why I am getting FramedSource ::getNextFrame():attempting to read more than once at the same time. 

  Where I am going wrong?

I can't tell what's wrong, without seeing your code.

Please post the code for your "OnDemandServerMediaSubsession" subclass, and for your "DeviceSource" based class.
