To add a YouTube video, you need the id code for the video. The easiest way to find this is to look at the URL of the You Tube page for the video. The string of letters and numbers after "v=" in the URL is the id code. So for the URL: http://www.youtube.com/watch?v=CCz1kmfqL7g the id code would be CCz1kmfqL7g. If you aren't sure what to use, you can add the whole url in place of the id code.
YouTube videos are embedded using two tags, with the id code for the video you want to show between them:
"id code" is the code from the URL. So in our example, you would use:
You can change the width and height of the video box, to a maximum of 425x355 pixels. For best results, the height should be about 5/6 (83.3%) of the width. Some examples of good ratios include 125x100, 200x160, and 250x200.
If you specify width and height, and those settings are not in proportion to the YouTube screen, then you will have empty space around the video. In most cases, the width determines the screen size in this situation.
Width is controlled with width="xxx", where xxx is the number of pixels. The default is 425 pixels.
Height is controlled in the same way with height="xxx". The default is 355 pixels.
If you intend to use a lot of YouTube videos on your wiki, you can make a template to make adding videos easier, and to display all videos in a standardized way. However, because of the order in which the template and the extension are processed, the <youtube> extension code itself cannot contain template parameters.
