/* Each video service is set up as follows
* service-name : {
* // initialization
* selector : 'object[data-url*=service], embed[src*=service]', // required: jQuery selector used to find the video ('video' or 'iframe[src*=service]' are other examples)
* initAPI : 'string added to the URL to initialize the API', // optional: the string must end with a parameter pointing to the video id (e.g. "&player_id=")
* embedOpts : { flashvars: {}, params: {}, attr: {} }, // optional: add any required flashvars, parameters or attributes to initialize the API
* // video startup functions
* init : function(base, vid, index){ }, // optional: include any additional initialization code here; function called AFTER the embeded video is added using SWFObject
* // required functions
* cont : function(base, vid, index){ }, // required: continue play if video was previously played
* pause : function(base, vid, index){ }, // required: pause ALL videos
* message : function(base, data){ }, // required for iframe: process data received from iframe and update the video status for the "isPlaying" function
* isPlaying : function(base, vid, index){ } // required: return true if video is playing and return false if not playing (paused or ended)
* }
*
* Function variables
* base (object) = plugin base, all video values/functions are stored in base.video
* vid (string) is the ID of the video: vid = "asvideo1"; so jQuery needs a "#" in front... "#" + videoID option default ("asvideo") + index (e.g. "1"); each video matching a service will have a unquie vid
* index (number) is the unique video number from the vid (starts from zero)
*
* var list = base.video.list[index]; list will contain:
* list.id = vid
* list.service = service name (e.g. 'video', 'vimeo1', 'vimeo2', etc)
* list.selector = 'jQuery selector' (e.g. 'video', 'object[data-url*=vimeo]', 'iframe[src*=vimeo]', etc)
* list.panel = AnythingSlider panel DOM object. So you can target the video using $(list[index].panel).find(list[index].service) or $('#' + vid)
* list.status = video status, updated by the iframe event listeners added in the video service "ready" function; see examples below
