Open Broadcaster Software with Local Capture

Last Updated: May 29, 2017 8:30 pm

In this tutorial, you will learn how to use Live Score with Open Broadcaster Software by using the local Window Capturing to integrate Live Score. This is a perfect solution if you run Live Score on the same computer with Open Broadcaster Software.

Using the Window Capture is a basic way when running the free Standard Edition of Live Score.


Start Live Score

We start by opening Live Score and selecting our sport.
Live Score will now start the main application with the sport you have selected.

Now it's time to add and prepare our scoreboard.



Add a Scoreboard

Let's add a new scoreboard by using the + button in the right scoreboard panel of the main window. This will open the layout gallery, where you can choose one or more of your available layouts.

After clicking on Add your scoreboard should appear in the center area of Live Score.
Now you can move it around by dragging the scoreboard with your mouse, zoom it or customize it.



Start Live Score Engine

We're done in Live Score.
The last thing we need to do is to start the Live Score engine.
Do this by pressing the blue start button in the top right corner of the main window.

This will start all timers and controllers that are necessary to update your scoreboard data properly, and to enable incoming iOS connections from your remote apps.




Start Open Broadcaster Software

It's now time to start your Open Broadcaster Software.
Do this on the computer that also runs Live Score.

OBS should now display an empty project - no input source or anything else.
So let's add a video or camera source.

Click on Add Video Capture Device and set up your camera feed.
Your video should now appear in the main window of OBS.



Add your Scoreboard input

It's finally time to add our Live Score scoreboard to OBS.

Click on Add Window Capture in the Sources section.
The Window Capture input allows us to directly capture a running application from your computer in OBS.

First we need to set a name for our new source.

In the appearing dialog afterwards, we have to select our window that should be captured.
Select Live Score, disable Capture Cursor and close the dialog by pressing OK.

Not working?

If you do not see Live Score in the preview after selecting it, please close the dialog. Go to Live Score and make sure that it is not minimized.
Bring Open Broadcaster Software to the front again and repeat the whole step.
This seems like a bug, that OBS cannot find minimized applications when creating input sources.


Crop the Overlay

Our next step is to prepare the scoreboard for our final integration.
This means we have to crop the screen, to only see the scoreboard, and then apply chroma keying to remove the background from the scoreboard source.


We start by opening the filter dialog for our source. Right-Click on the scoreboard layer while selected, and click on Filters.

Add a Crop/Pad filter and adjust the Left/Top/Right/Bottom values below the preview until you only see your scoreboard and the background color.



Apply Chroma Keying

Add a new Chromy Key filter below the crop/pad filter.
Now select the Key Color Type below the preview to match your background color.

Play around with the sliders below until your background color disappears and only your scoreboard remains visible.

For faster results, use the Similarity slider if your background color matches your Key-Color-Type.

Improve your results by adjusting the sliders and settings until you are satisfied.

Close the filter dialog and you should now only see the scoreboard above your camera feed.



Bringing it all together

Everything is set up correctly.
All we need to do now is to adjust the size and move it to the place where you want it to appear. Drag the edges of the red rectangle in the preview to adjust the size or just drag and drop the whole scoreboard to your preferred location.





That's it, you're ready to go


You can now go on with finer adjustments, like positioning the scoreboard, scaling it, and proceeding with your usual broadcasting workflow.
