RE: Streaming with Media Source

How are you preparing your source files? Do they have the initialization box/packet (normally on any mp4 or webm file) for at least the first segment? 

I've created a MSE player for DASH mp4 files.. I'm not an expert, but I've gotten it to work on a single stream on IE and Firefox. I would like to get it to work on chrome, so maybe we can share experiences. 

I don't know if this will help, but here's a blog post I wrote on one way to do it (there seems to be quite a few) http://blogs.msdn.com/b/mediastuff/archive/2014/02/19/video-streaming-without-plug-ins-or-special-servers.aspx

Subject: Streaming with Media Source

Hi,

For [1] I have started to implement Streaming for audio and video using the Media Source API, the app is retrieving chunks and is appending them to the "source" of audio/video tags.

This was supposed to be simple but it is not, the API (or at least the Chrome implementation) seems to handle only adaptive rate/manifest structures both for mp4 and webm, it's unclear if the audio tag is supported.

I am not an expert in video/audio format but I don't see very well what's the issue to append chunks to a destination, or to turn it into a stream (since I am participating to the Streams API, I know it's not there yet) outside of other interfaces such as WebRTC.

For the final phase of the project, WebRTC will be used but with DataChannels, so the issue remains.

I have looked in all existing APIs and unless I am missing something, I still don't see how to achieve this simple thing, how can it be done?

Regards,

Aymeric
