Hi, Some MiscellaneousCommand will affect video decoder, such as videoFreezePicture. The code below can not receive videoFreezePicture. BOOL H323Connection::OnH245_MiscellaneousCommand(                  const H245_MiscellaneousCommand & pdu) {   H323Channel * chan = logicalChannels->FindChannel((unsigned)pdu.m_logicalChannelNumber, FALSE);   if (chan != NULL)     chan->OnMiscellaneousCommand(pdu.m_type);   else     PTRACE(3, "H245\tMiscellaneousCommand: is ignored chan=" << pdu.m_logicalChannelNumber            << ", type=" << pdu.m_type.GetTagName());   return TRUE; } Bian
