*
* Elementary comes with two object that help design application that need
* to display video.
*
* The first one, Elm_Video, display a video by using Emotion.
* It embeds the video inside an Edje object, so you can do some
* animation depending on the video state change. It also implements a
* resource management policy to remove this burden from the application.
*
* The second one,
* Elm_Player is a video player that need to be linked with an Elm_Video.
* It take care of updating its content according to Emotion event and provide a
* way to theme itself. It also automatically raises the priority of the
* linked Elm_Video so it will use the video decoder, if available. It also
* activates the "remember" function on the linked Elm_Video object.
*
* Signals that you can add callback for are :
*
* "forward,clicked" - the user clicked the forward button.
* "info,clicked" - the user clicked the info button.
* "next,clicked" - the user clicked the next button.
* "pause,clicked" - the user clicked the pause button.
* "play,clicked" - the user clicked the play button.
* "prev,clicked" - the user clicked the prev button.
* "rewind,clicked" - the user clicked the rewind button.
* "stop,clicked" - the user clicked the stop button.
*
* Default content parts of the player widget that you can use for are:
* @li "video" - A video of the player
