Thanks Simon. The trace files for 1) Sample to Sample & 2) Salyens(4CIF) to Sample have been attached alongwith.

Also, the capabilities are being added as follows:

// add codecs H323PluginCodecManager & codecMgr = *(H323PluginCodecManager*) PFactory<PPluginModuleManager>::CreateInstance("H323PluginCodecManager"); PPluginModuleManager::PluginListType pluginList = codecMgr.GetPluginList();

H323Capability* cap[10]; this->AddAllCapabilities(0, P_MAX_INDEX, "*");

PStringArray preferenceorder;

PString str1_cif = "H.261"; PString str1_qcif = "H.261-QCIF{sw}";

PString str3_cif = "H.263-CIF"; PString str3_qcif = "H.263-QCIF{sw}"; PString str3_4cif = "H.263";

if(a4CIF) { m_nTxvideoWidth = i4CIF.m_nWidth;//size

m_nTxvideoHeight =i4CIF.m_nHeight;// if(aH263) { preferenceorder.AppendString(str3_4cif); SetVideoFrameSize(H323Capability::cif4MPI); } } else if(aCIF) { m_nTxvideoWidth = iCIF.m_nWidth; m_nTxvideoHeight =iCIF.m_nHeight; m_nbw = BW * 2; m_nframerate = FRAMERATE * 2; if(aH263) { preferenceorder.AppendString(str3_cif); } if(aH261) { preferenceorder.AppendString(str1_cif); } } else if(aqCIF) { m_nTxvideoWidth = iQCIF.m_nWidth; m_nTxvideoHeight =iQCIF.m_nHeight; m_nbw = BW * 1; m_nframerate = FRAMERATE * 0.5; if(aH263) { preferenceorder.AppendString(str3_qcif); } if(aH261) { preferenceorder.AppendString(str1_qcif); } } else { // no video codec added in capability } capabilities.Reorder(preferenceorder); for(int i = 0; i< 10; i++) { cap[i] = capabilities.FindCapability(i); }

Thanks Taranpreet
