Re: WWDM 2009

Hi Greg, hi all

Do you know something I don't or are you just guessing like me?

The iPhone is not my primary concern, and I mostly worry about the evolution of the QuickTime as a cross-platform (osX/Win32) player for H.264 content (and more importantly as a plugin).

In the futur, QT might not be the most important H.264 player.

We have Flash supporting H.264 (but not with the right set of streaming protocol for DSS and QTSS).
Maybe in the futur WMP (from W7) will support it too (but with what set of streaming protocol).
And of course we can always ask VLC to the rescue as it is supported on osX/Win32/Linux/other... and with VLC reaching 1.0 maturity now might be a good time.

Whatever the player (or plugin), in most case you will want to stream it with DSS/QTSS.

I assume that whatever is the new "QuickTime X-style HTTP streaming of audio and video" (iPhone) is, it is the same as "QuickTime X HTTP streaming" (Snow Leopard) and QT will not loose it's current support for RTSP+RTPU (let's say over UDP 554) and RTSP+RTPT (let's say over TCP 80).

The question everyone with VOD content and an existing DSS/QTSS might legitimately ask themself is: "What should I add to my infrastructure to support this new(?) thing and maybe instantly be able to reach millions of iPhone while providing yet another way for QT to reach my content".

So what I try to find out if it is different or similar to what we know.

If this is just about the HTTP progressive download we know... then Apache will do the trick (beware the port conflict with DSS if you enable "over http").
If it is a special HTTP progressive download that permit seeking (like it is possible to do with flash without RTMP and with some module for apache or lighthttpd) then the world will need some specification or some open source code to support it.

Then if it look and feel like HTTP, will proxy and reverse proxy support it transparently or the internet architecture will need an upgrade.
Will CDN out there support this (presumably) new streaming method... with existing infrastructure.

Also, it is not clear to me if we are talking about VOD content only, or if LIVE is also affected (where I think progressive HTTP download is not really an option).

I am not under an NDA so I am guessing.
Maybe 18 June will give us more information about the iPhone part of the story.
Maybe those under NDA will be able to speak freely match with our guessing.
Maybe the QT-X new thing is the same as the iPhone 3.0 new thing and the mystery will disapear (or I will have to wait until September).

I hold my breath until the 18th. ;-)

HTTP streaming for iPhone is not the same protocol as HTTP streaming in QTSS/DSS.
HTTP streaming in QTSS/DSS is a tunnelling method for RTSP and is true streaming.
HTTP streaming for iPhone is NOT, and can be served from a web server.
There is no need to use QTSS/DSS for this method. That is the idea of HTTP streaming for iPhone.

I guess they are moving away from RTSP and DSS/QTSS.
They didn't make iPhone's media player RTSP compatible. That's the sign,
I think.

Now I have two questions.

A. Do I need to setup two streaming servers (DSS and
Streaming-Enabled-Apache) to cope with both existing contents
(especially I'm using SMIL 1.0) and new contents to QuickTimeX and
iPhone? I guess Apple will not upgrade QTSS/DSS to cover HTTP streaming
for iPhone.

B. Where will be the discussion place for Streaming-Enabled-Apache? Here
or somewhere else? I hope Apple to release the source code of HTTP
streaming modules for existing apache web servers on all platforms not
only for their Snow Leopard server.
