IIS Live Smooth Streaming

David Nelson takes us on a walk through of IIS Live Smooth Streaming now in Beta.   IIS Live Smooth Streaming enables adaptive streaming of live events to Microsoft Silverlight clients and is an extension for Internet Information Services (IIS) 7.0 – it delivers compelling, uninterrupted live video streams that allegedly instantly adjust quality (bit rate) to match changing network and CPU conditions at the client.

I am very curious to see how this is going to work when Enterprise end users hit on an IIS 7 video that is Smooth streaming – fat live video pumping over HTTP into a locked down network, sounds like the kind of bandwidth consumption that could bring systems down… especially when systems are cloaked, how is the intelligence of the smooth streaming going to work for video coming in to the Enterprise from the outside?

The following prerequisites must be fulfilled to install IIS Live Smooth Streaming – Beta:

• You must use IIS 7.0 running on Windows Server 2008 or Windows Vista® with Service Pack 1 (SP1).
• To manage IIS Live Smooth Streaming using the IIS Manager user interface, the IIS Management Console for IIS must be installed. You can install the IIS Management Console role service for Web Server (IIS) in Server Manager.

The following options are available for installing IIS Live Smooth Streaming - Beta:

• Web Platform Installer 2.0 Beta
• Web Platform Installer 1.0
• Windows Installer files (for 32-bit and 64-bit versions of the Windows Server 2008 or Windows Vista SP1 operating systems)

The “Installation Notes” section of the IIS Live Smooth Streaming – Beta Readme contains detailed instructions for each of these installation options.

Here is an interesting thread from the WMTALK LIST:

For Live Smooth Streaming today, you've got just three products announced.

Inlet Spinnaker (with a forthcoming update) ENCODES
Windows Server 2008 (with Live Smooth Streaming module for IIS7) HOSTS
Silverlight 2+ CONSUMES

A live encoder basically pushes the same chunks the server would deliver to the
client to the server, with some extra metadata and stuff.  So the file format is
still Fragmented MPEG-4.  Supported codecs are:
        VC-1 and WMA 10 Pro for Silverlight 2+
        H.264 and AAC-LC for Silverlight 3+

Subject: Live Smooth Streaming: Goesinto & Goesoutta

Hi All,

I've read a bunch now about Live Smooth Streaming, and there's chatter about
mpeg4, H.264, etc., but I'm still confused about who does what to whom. If
anyone can help put the pieces together, that would be nice. What I'd like
to understand better right now is the goesinta and goesoutta formats for
each piece

WME9
EE2 SP1
IIS7
WMS/2008
Silverlight Player
WMP (v11?)

Starting points:
EE2 SP1: what input formats does it accept? What will it output to IIS7
(e.g., native mpeg4, a proprietary format, etc.)? What will it output to
WMS/2008? Will it output directly to a Silverlight player (and if so, in
what formats)? Will it output directly to a WMP?

WME9: we're probably familiar enough with input formats, and we know it will
output to WMS/2008 and to WMP 11 in a proprietary ASF format. Will it output
to an IIS7 publishing point? Will it output directly to a Silverlight
player?

IIS7: for a Live publishing point: what input formats will it accept (e.g.,
only a proprietary format from EE2?)? What are the output formats (e.g.,
only the .ismv chunked up smooth streaming file format?)?

WMS/2008: I'm guessing there's not much change. I assume it will accept
input from EE2, but not EE2 smooth streaming?  I also assume the output is
the same (wma/wmv in an asf wrapper that can be digested by Silverlight or
WMP?)?

Silverlight: I think I understand that it can receive a million little
chunks of a video as miniscule progressive downloads from IIS7 Live Smooth
Streaming. Can it also receive that from WMS/2008? Will it accept other
input formats like mp3, mpeg4, etc. (I mean, in native mode, not in
programmer-hell mode -- meaning, can I just point an mp3 stream at it?)?

Maybe some of these answers should be obvious to me.... I'm also hoping to
learn of interplay between these systems and the broader ecosystem out
there.  In particular streaming live and on-demand audio and video to the
wealth of smart phones that don't support Windows Media, the iPhone in
particular. For me, reaching that market is mandatory.

Thanks,

Harry

A word of warning:  To all those who dabble in the world of streaming media, I recently installed VLC Media Player on to my desktop and discovered that it became the default player for ALL MEDIA content in Fire Fox and destroyed my gorgeous embedded Windows Media video content’s functionality…  We are totally dependent on the reliability of players and plug ins in this game and when Windows Media Player embed tags stopped working completely, I discovered that the only fix was… Uninstall the VLC Media Player…

VLC is great, but if you work in multiple formats/players/embed tags, BEWARE…  It’s a MIME type hog in FF…  Anyone have a better fix for this yet other than this for the VLC Media player ?  Of course, if you use OBJECTY in your tags, maybe you can skip all that pain, but if you can’t change the tags… You know what to do!

Happy Streaming, Suckers!
