Migrating from Windows Media Services to IIS Smooth Streaming

einar — Fri, 20 Nov 2009 09:24:37 GMT

Hi I would like to know if there is any documentation about migrating media delivery from Windows Media Services (WMS) to IIS Smooth streaming? Today I serve my content using WMS. My content is usually just one bitrate wmv file in Windows Media 9 format (video and audio) in an asf container. I also have another version of my content for mobile devices such as the iPhone. This is a lower resolution version of the same file encoded using AVC1(h264)/ACC in an mp4 container. My question are: Do I need to re-encode my content for smooth streaming or can I somehow generate the Manifest files according to the already existing keyframes in my media files? Also, would it be possible to offer two bitrates in different formats? The idea is to use the lower resolution (and lower bitrate) format (iPhone version) together with the higher bitrate version of the video. Clients seeking around or experiencing bandwith problems could therefore start by playing the lower bitrate and then switch to the higher bitrate version. Furthermore, could I "smooth stream" the lower bitrate version directly to the iPhone as well (as shown (or almost shown..) in ScottGu's keynote at PDC09)?

Hi, Gissah,

Thanks for asking about this. It is a known issue, with a known fix. Dave Nelson wrote an excellent blog post about the issue and how to fix it at http://blogs.iis.net/dmnelson/archive/2009/05/14/updating-browscap-ini-for-internet-explorer-8.aspx.

Hi, Gissah,

It seems you are documenting, piece-by-piece, your investigation into Windows Media multicast. :-)

As you must know, the text you provided represents the contents of an encoded NSC file. More information, including information on the encoding algorithm, can be found on MSDN. A good starting point is here: http://msdn.microsoft.com/en-us/library/cc236197(PROT.10).aspx.

Hi, Gissah,

This usually means that you need to generate a new multicast announcement (NSC) file. See http://technet.microsoft.com/en-us/library/cc753602(WS.10).aspx for information on how to do this.

Nope, Windows Server only - but it looks as if you may have already received that answer on http://forums.iis.net/t/1160929.aspx. :-)

Hi, Gissah,

Does this WMS firewall article help? http://www.microsoft.com/windows/windowsmedia/forpros/serve/firewall.aspx

Hi, Gissah,

If you already have Windows Server 2008 Enterprise, then you just need to download and install WMS from http://www.microsoft.com/downloads/details.aspx?FamilyID=9ccf6312-723b-4577-be58-7caab2e1c5b7&displaylang=en. Does that answer your question? If not, could you please be more specific?

If all the valid requests will be coming from a specific website, would IP Address authorization meet your needs? http://technet.microsoft.com/en-us/library/cc770273.aspx

Hi, Justin. You can absolutely stream a live video with WMS. At a high level, you will want to create a new publishing point using the Add Publishing Point wizard (see http://technet.microsoft.com/en-us/library/cc772032.aspx), source from an encoder (see http://technet.microsoft.com/en-us/library/cc731559.aspx) such as the older Windows Media Encoder or the new Expression Encoder 3 (see http://www.microsoft.com/windows/windowsmedia/forpros/encoder/default.mspx).

I hope this helps you get started.

Windows Media Services Plugins

scarekrow76 — Tue, 08 Sep 2009 16:13:17 GMT

Hiya. I'm hoping someone might be able to send me some sample code or point me towards a tutorial or blog post...

I've just dived into the world of Windows Media Services. For a current project I need to be able to restrict access to certain WMV files housed upon a streaming media server.

For various reasons, the best method to do this (as far as I can see) is to use a URL Referer plugin for Authorization, so that the WMV files can only be embedded and accessed from a specific website. As WMS can't handle this out-of-the-box it looks as though I will need to write a custom plugin. Oh dear!

If anyone has a better idea, I would be very glad to hear it.
