Video JS - IMA3 Ad Scheduler with Fallbacks

VideoJS is an html5 (mainly) video player without dependencies to external libraries (jquery etc) I am implementing IMA3 plugin to the player to retrieve and play ads during the video ([login to view URL]) I need a plugin that will schedule ads to play pre, mid and post roll If an ad request has error it must check if an ad is available to fallback list of tags before it tries any other adpod. tags = ['tag1','tag2','tag3']; So if there is a preroll ad and a midroll in second 1: it must request an ad before the video starts. If the response of tag1 returns no advertisement it must try the tag2 and tag3 before it starts the video. Then it starts the video and it goes to second 1 where it tries the list of tags in that point of time. If tag2 returns an ad, it stops. I mean it doesn't go to tag3. tag2 and tag3 are error fallback tags in other words. The scheduler should look like: scheduler { preroll: tagListPre, midroll: [[1, tagListMid],[10,tagListMid]], midrollrepeat: [120,tagListMidR], postroll: tagListPost, } As you see this should run a preroll, a midroll at second 1, a midroll at second 10, a midroll every 120 seconds (time: 00:02:00, 00:04:00,00:06:00.....) and a postroll when the video finishes. Each has different lists of tags as you notice. It must always resume the video when and only when the ad finishes or if no ad is returned, if it is in preroll position, OR continue the video without interrupting user watching, until it finds an advertisement if it is in midroll position. It must work even when autoplay is set for desktops and on click/touchend for desktop/mobile devices.
