CrossBarFound = VideoCapture1.Video_CaptureDevice_CrossBar_Init();

Get available inputs 

VideoCapture1.Video_CaptureDevice_CrossBar_ClearConnections;
cbCrossbarVideoInput.Clear;

for i := 0 to VideoCapture1.Video_CaptureDevice_CrossBar_GetInputsForOutput_GetCount('Video Decoder' ) - 1 do
  cbCrossbarVideoInput.Items.Add(VideoCapture1.Video_CaptureDevice_CrossBar_GetInputsForOutput_GetItem('Video Decoder', i));
VideoCapture1.Video_CaptureDevice_CrossBar_ClearConnections();
cbCrossbarVideoInput.Clear();

for (int i = 0; i < VideoCapture1.Video_CaptureDevice_CrossBar_GetInputsForOutput_GetCount("Video Decoder"); i++)
  cbCrossbarVideoInput.Items.Add(VideoCapture1.Video_CaptureDevice_CrossBar_GetInputsForOutput_GetItem("Video Decoder", i));

Apply selected input 

VideoCapture1.Video_CaptureDevice_CrossBar_ClearConnections;
VideoCapture1.Video_CaptureDevice_CrossBar_Connect(cbCrossbarVideoInput.Items[cbCrossbarVideoInput.ItemIndex], 'Video Decoder', true);
VideoCapture1.Video_CaptureDevice_CrossBar_ClearConnections();
VideoCapture1.Video_CaptureDevice_CrossBar_Connect(cbCrossbarVideoInput.Text, "Video Decoder", true);
