How to MPEG-DASH video streaming in iOS?

Question

I am trying to write a java script based implementation of MPEG-DASH for video streaming . I have referenced following documents

• dash.js - https://github.com/Dash-Industry-Forum/dash.js/wiki
• Google Shaka Player - https://github.com/google/shaka-player

These libraires are using MSE (Media Source Extensions)

My understanding

MPEG-DASH is an international standard for streaming video . but is currently not naively supported in iOS devices. In other browsers and devices, it requires a java script library or a video player that supports MPEG-DASH. (eg: Dash.Js ,Shaka player etc.)

And another streaming technology is HLS . It is an adaptive streaming communications protocol created by Apple. The Safari browser can play HLS streams within a web page, iPhone, and iPod touch devices.

Here we can see that MPEG-DASH (because of MSE) currently not naively supported in iOS devices.

Now my doubts

1. How can we stream MPEG-DASH videos in iOS with out MSE ?
2. How Facebook and other streaming media services play their videos ? is it with HLS only ?

Any suggestion/explanations would be more helpful .

Answer 1

1. You can’t.

2. Yes they use HLS. iOS 10 and above support fmp4 in HLS. so the only difference between dash and hls is the manifest.
