[SOLVED] Videos using Gallery

I want to display videos using Gallery. I have uploaded the video and created thumbnails for it. My main problem is that when you click on the video, it forces you to download the video but I want the video to play in the browser.

If I am not making sense here are examples:
My site showing how it currently works:

I found this guys sight when searching for my answer:
http://www.unicyclejester.com/gallery/vids/?g2_page=1

When I go to his sight I can view the videos directly on the webpage.

How do I do this?

Do I need ffmpeg for this? If so, is there a basic guide to ffmpeg somewhere?

I have spent 2 hours searching for my answer and I give up. If there is already a post with my answer please just direct me to it.
