Add the following to your challenge launch file somewhere inside the tag

<!-- Launch nodes for video streaming -->
<node pkg="challenge_visualization" name="merge" type="merge.py"/>
<node pkg="web_video_server" name="video_server" type="web_video_server"/>

Running:

After running your final challenge launch file with the added merge and web_video_server nodes open a web browser and navigate to http://teamname.beaver.works:8080

Select the visualiztion/converter image topic in the browser.

Ctrl + + will increase the video size

Critical Note:

Only one team member should open the video feed in their browser - each open video feed takes 10%-20% of the available CPU. For the final challenge, we will have one feed open on large monitors for the audience to view.
