Mediafilter

Mediafilter is a module that extends an existing text format like Filtered HTML or Full HTML. It converts Youtube- and Vimeo links to embedded videos using their HTML5 api's.

Enable this filter in a text-format. The weight must be lower than 'Limit allowed HTML tags' or else it wont work. Users can post all kinds of Youtube or Vimeo links and this filter will convert it to an embedded video in an iframe. Admins can set options to unify the players:

Youtube iframe:

• Width
• Height
• Disable fullscreen player
• Autohide player controls when playing
• Autoplay as soon as video is loaded
• Set the color of the progressbar to white
• Hide the player controls
• Loop the video (HTML5 player only)
• Hide the Youtube logo
• Display related videos at end of video
• Display a light controlbar instead of dark

Vimeo iframe:

• Width
• Height
• Player control color
• Enable pausing video when another video is played
• Autoplay as soon as video is loaded. (Note that this won’t work on some devices.)
• Enable the badge on the video.
• Show the user’s byline on the video
• Loop the video.
• Show the user’s portrait on the video.
• Show the title on the video

So basically Mediafilter is a module that makes posting Youtube video's as easy as can be. No knowledge of HTML or iframes is required. Just post a link like:
https://www.youtube.com/watch?v=Tt78_fr5cj0, http://youtu.be/Tt78_fr5cj0, http://vimeo.com/32979765
and this filter will do the rest. It extracts the video ID and then it builds an iframe around it with your option-set.
