youtube and google videos
 

how do you add the option of playing youtube and other videos within the thread/post instead of having to goto the host site.

I've created a custom [youtube] BBcode tag that lets you do this. You can do it a number of different ways, but mine is like:

[youtube]YouTubeVideoID[/youtube]

where YouTubeVideoID is the code that YouTube gives to each video on its site. That ID is a mix of characters, symbols and numbers. and can be found by looking at the URL to the YouTube video. It's the value in the "v=" name/value pairing in all YouTube URLs.

To do it in AdminCP, go to Custom BBcode > Add New BBcode. Call it YouTube Video, or whatever you want. For "Tag" enter youtube. For replacement, enter:

That should do it!
