Video JS - IMA3 Ad Scheduler with Fallbacks -- 2

VideoJS is an html5 video player without dependencies to external libraries (jquery etc) I want to implement IMA3 to the player to retrieve and play ads during the video (a plugin already made from Google for Video JS is [login to view URL])... you can either use that plugin or make your custom IMA3 implementation I need the plugin to have a "scheduler" 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 in the 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: 1. it must request an ad before the video starts. 1a. If the response of tag1 returns no advertisement it must 1b. try the tag2 and if again an error is returned try tag3 before it starts the video. 2. Then it starts the video and it goes to second 1 where it tries the list of tags in that point of time. 2a. If tag2 returns an ad, good. It stops looking the rest of the tags. 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. Each list can contain as many ad tags as I like. The important is to try the first, if the first fails go to second, then to third and so on until the list finishes or an ad is returned. 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 (this means that in midroll it checks for an ad without pausing or starting the video until an ad is found).
