void EnumMKVCompressors(IltmfConvert *pConvert, HWND hwndParent)
{
   IltmfTargetFormats *pTargetformats;
   IltmfTargetFormat* pTargetformat;
   // set the target format to MKV
   pConvert->put_TargetFormat(ltmfConvert_TargetFormat_MKV);
   pConvert->get_TargetFormats(&pTargetformats);
   pTargetformats->Item(ltmfConvert_TargetFormat_MKV, &pTargetformat);
   pTargetformats->Release();


   


   // show the target format profile (properties) dialog if available.


   VARIANT_BOOL vbDialog;


   pTargetformat->HasDialog(ltmfTargetFormat_Dlg_Profile, &vbDialog);


   if (vbDialog)


   {


      pTargetformat->ShowDialog(ltmfTargetFormat_Dlg_Profile, (long)hwndParent);


   }
