Re: Streaming with Media Source

Thanks, yes we can share experiences (I thought it was not implemented 
in FF, from which version?), I saw your tutorial already, very well 
explained, what I want to do is a bit different and very simple:

Usually you use something like <video src='movie.mp4' />, then you get 
the chunks via HTTP and the video is displayed.

I want to do exactly the same thing, I receive the chunks (from the 
Peersm protocol via WebSockets or WebRTC Data Channels) and MSE displays 
the movie.

I have read from some Aaron posts that MSE only works with fragmented 
files, in addition you have to submit the fragments as defined in the 
manifest file (or at least the initialization segment? I have not tested 
this for now).

It does not work for mp3 (as far as I saw the Web Audio API does not 
allow to do what I want to do too).

Format available inside the browsers are not numerous, now the API is 
rectricting to fragmented files, so I find it extremely limited.

I have some hard time believing that no API did envision that you might 
want to stream video and audio based on the received chunks, is it the case?

Do IE and FF only implement it too for fragmented files?
