13. Dynamic Metafiles
Windows Media Metafiles can be dynamically generated from ASP
Typical corporate scenario:
Customer deploys multiple WM Servers close to the end users
Users access centralized web site to find content they wish to view
ASP page examines users IP address and generates Dynamic metafile directing them to the closest available Windows Media Server
Typical Internet scenario:
Personalized advertising

14. Using Metafiles Best practices for streaming
Use the right extension
For Audio: Use .WAX extension
For Audio/Video: Use .WVX extension
Copy file to Web server
Set the Mime Type on your Web server
Always hyperlink to a metafile!

15. MIME Types Required for accessing metafiles from a web server
Document on Jumpstart CD & Web site
Configure as follows:
.WMA audio/x-ms-wma
.WAX audio/x-ms-wax
.WMV video/x-ms-wmv
.WVX video/x-ms-wvx

16. Programming The WM Player
Extensible filter-based architecture for network and local multimedia playback
Leverages DirectX® foundation: DirectSound® for audio mixing and low-latency audio, Direct3D® for hardware 3D acceleration
Embed and control the Player Control/Plug-in via scripting and programming languages
Visual Basic® Scripting Edition or JavaScript/JScript™
COM interfaces with Visual Basic or Visual C++®/Visual J++®
Fully scriptable Netscape Plug-in supports all properties, methods, and events
Windows Media SDK fully documents interfaces
