On demand streaming on all platforms

Hello there, We where evaluating JWplayer to integrate in our product. There are few queries we have: 1. Assumption: We have video files like .mp4, wmv, mov stored in S3, we can convert them to support on-demand streaming 2. Can we use Cloudfront to stream contents, which streaming protocol (RTMP,HLS,HDS) is correct to support on all platforms like web, mobile apps (android,ios) 3. Does JWPlayer supports ondemand streaming on all platforms like web, mobile apps (android,ios) ?? we have web application implemented using AngularJS and Mobile apps using Ionic.
