It has been decided that VideoSequencer will be an external library for popcorn.js. There is a lighthouse ticket [https://processing-js.lighthouseapp.com/projects/52212/tickets/97-create-a-video-wrapper here]. The Github repository for VideoSequencer can be found [http://github.com/cadecairos/VideoSequencer here].
 
duration is the total length in seconds of all the videos.<br />
segments[] is an array of the video elements in the Sequencer<br />
<br />
VideoSequencer currently contains these methods:<br /><br />
 
*VideoSequencer() - Constructor <br />
*play() - Plays the currently active video<br />
*pause() - Pauses the currently active video<br />
*togglePlay() - if the active video is playing, it is paused. and vice-versa<br />
*add(src, len, index) - adds the URI in src of length len (in seconds) to the list of segments<br />
*seek(time) - calculates which segment is playing at the specified time, and swaps to it, then seeks to the right position (NEEDS WORK) <br />
*swap(seeking) - removes the active video tag from the DOM and displays the inactive video. It then creates a hidden tag and begins pre-loading it. if seeking is set to true, it will remove both tags. <br />
*addEventListener(event, callback, useCapture) - adds the event and callback to the queue if it does not exist already, and then adds it to the currently playing video.<br />
*removeEventListener(event, callback, usecapture) - if event and callback exist in the event queue, they are remove from the queue and also from the currently playing video.<br />
*addListenersToCurrentVideo(listener) - adds all callbacks in the queue for "listener" to the currently playing video<br />
*createVideoTag(width, height, controls, hidden) - creates a new video tag with the specified settings and returns it.<br />
*update() - checks to see if the active video is about to end. If the video is about to end it calls swap().<br />
*convertXML(xmlDoc) - parses the video segment data into the VideoSequencer.<br />
*getSegmentData(segDataFile) - creates an XMLHttpRequest to get the segment data XML, then callse convertXML(xmlDoc)<br />
*calculateDuration() - calculates the duration of all the videos in the segment object and returns the value.
