Hi thiagopnts:
it(@v0.0.3) plays a mp4 file on ios10+, it shows audio and video;
it(@v0.0.3) plays a m3u8 file on ios10+, it shows audio but no video, what's wrong with it?
pass the parms like here:
var params = {height: window.innerHeight, width:window.innerWidth,
autoplay: true, container: container.el, source: container.playback.el};
this.viewer = new Video( params );
