Hi,

Take a look on the H323CodecExtendedVideoCapability::OnSendingPDU function.

I have had some issues with Extended capabilities and have fixed the issue only after change the view order - we need to look the .table first and only if it empty - work with extCapabilities.

For current implementation we always work the extCapabilities only because it always has GetSize()>0 (otherwise we return FALSE at the beginning of this function).

PBoolean H323CodecExtendedVideoCapability::OnSendingPDU(H245_VideoCapability & pdu, CommandType ctype) const 

{ 

    if (extCapabilities.GetSize() == 0)

        return FALSE;

   // bla-bla-bla

    

    if (extCapabilities.GetSize() > 0) {

      caps.SetSize(extCapabilities.GetSize());

      for (PINDEX i=0; i< extCapabilities.GetSize(); i++) {

         H245_VideoCapability vidcap;

         ((H323VideoCapability &)extCapabilities[i]).OnSendingPDU(vidcap,ctype);

         caps[i] = vidcap;

      }

    } else {

      caps.SetSize(table.GetSize());

      for (PINDEX i=0; i< table.GetSize(); i++) {

         H245_VideoCapability vidcap;

        ((H323VideoCapability &)table[i]).OnSendingPDU(vidcap,ctype);

        caps[i] = vidcap;

      }

    }

  return TRUE;

}

Thanks
