Here is an example of how to fill a combobox with all available input video formats for a live source and select a current format:

C#

M_VID_PROPS vidProps;
int fCount;
m_objLive.FormatVideoGetCount(eMFormatType.eMFT_Input, out fCount);
if (fCount > 0)
{
    for (int i = 0; i < fCount; i++)
    {
        string name;
        m_objLive.FormatVideoGetByIndex(eMFormatType.eMFT_Input, i, out vidProps, out name);
        comboBoxVF.Items.Add(name);
    }
    // Get current format
    int nCurrent = 0;
    try
    {
        string strName;
        M_VID_PROPS _vidProps;
        m_objLive.FormatVideoGet(eMFormatType.eMFT_Input, out _vidProps, out nCurrent, out strName);
    }
    catch (System.Exception) { }
    // Select a current format
    comboBoxVF.SelectedIndex = nCurrent;
}
