With widespread broadband adoption, the continued shrinking cost of disk space, and the availability of the Adobe Flash Player and Flash video, it's no wonder that video sharing on the Internet is insanely popular. Sites like Google video and YouTube got the ball rolling, but now there are niche video sites everywhere. So, how can you get in on the action? How can you use technologies such as PHP, Flash, and Adobe Flex to build your own video sharing site? Turns out, it's a lot easier than you think.

This article walks you through building the PHP portion of the site as well as building a movie viewer in Flash using the Flex framework. To build a simple version of YouTube (or a MyTube, as it were), you should have a couple of tools in place.

On the server side, you first need PHP and MySQL. You'll use MySQL to store the data about the movies (for example, the file name for the movie, the thumbnail file, the height and width of the thumbnail, the title, and the description). PHP will do the work of formatting pages, both HTML and XML, depending on how you want to do it.

You also need an open source utility called ffmpeg to do the work of converting the video from whatever format your user uploads into a Flash Video (FLV) file. The ffmpeg utility can also generate a thumbnail snapshot of a frame from the movie for use when you present the list of available movies. Lest there be any doubt, ffmpeg is your new best friend in the world of video sharing. It's an amazing utility that is powerful, easy to use, and well documented.

On the frontend, I show several different user interface approaches. The first uses a hybrid HTML/Flash approach similar to YouTube. The second approach uses a completely Flash-based interface. For both of these approaches, I use the Flex framework to build the Flash applications that view the video and later to list the available videos and provide navigation
