Unsupported Uint8Array.from method on IE

Created by: qchroman

Hello,

It is great news that 2.5 now supports Smooth Streaming assets. Thank you for this great addition! I have noticed small issue thought. It seems that Uint8Array.from is not supported by IE and it fails to playback the stream here

ISOBox.prototype._writeData = function(data) {
  if (data instanceof Array) {
    data = new DataView(Uint8Array.from(data).buffer);
  }
...

I use a quick fix on my side by including the Polyfill described here.

Hope this helps for future releases.
