create phonegap app with own video player

Hello, this is probably an easy job for someone how knows what he / she is doing. The task: - build mobile app for ios and android by building upon code "Sensation" from codecanyon: [login to view URL] - customize and integrate a mobile video player that will receive a json playlist file and will have some very specific features e.g. - let user switch between several audio tracks and video tracks - can play 3 audiofiles and 2 video (screen in screen) at the same time - show user several overlays (images, text) - loop videos smoothly - let user push video to chromecast / apple TV - let user choose resolution - make it offline available for smoother playback and use without internet connection. All data will be hosted on AWS S3, all video data will be hosted in mp4 and probably HLS ready files.  The skills: - extensive knowledge in video player development / streaming - extensive knowledge in hybrid apps & onson UI The questions: - what development stack would you use to create the best possible video experience for out client? - what could we do to speed up the development? - we are developing the desktop front end in bootstrap - how would you do it to reduce the amount of development effort? The reason: - running a web based html5 player in a mobile browser has too many restriction for our use case. Looking forward to you proposal.
