The main problem with iPhone and most if not all android phones, is it will not play a windows media mms webstream out of the box. The server encoder level solution appears to be this,
Smooth Streaming Servers
Smooth Streaming Servers provide great new features that are not currently available through Windows Media Servers. One of the best features is video streaming directly to the iPhone, iPod Touch and iPad, without the need of an App. The Apple devices can open the video stream directly when the video feed’s address is entered into the address bar in Safari.
You might encounter this service under the name of Silverlight Streaming, because Silverlight is the only software that supports this technology. Also, you can encode your stream with Expression Encoder. It’s the only software available for this technology and you need to purchase a license in order to be able to use it.
Another great feature of Silverlight Streaming is that is optimizes playback of content by switching video quality in real time. Viewers with good internet connections will experience high quality video, while viewers with slower internet connections or slower computers, will receive the appropriate video quality for their capabilities.
The Silverlight Streaming technology provides an uninterrupted and buffer free video streaming experience, whether it’s live or on-demand and no matter the quality of the connection in use.
Smooth Streaming is especially recommended for streaming to iPhone users. The application uses the existing video capabilities of iPhone, so additional codes and settings won’t be necessary.
For live streaming and streaming for mobile devices, you must purchase Microsoft Expression Encoder 4 Pro. The software costs $199.95 and you can purchase it by accessing this link
Server side discussion here
“To create Smooth Streaming presentations, the same source content is encoded at several quality levels, typically with each level in its own complete file, using a compression tool such as Expression Encoder 3 or a product from one of our many partners. Content is delivered using a Smooth Streaming-enabled IIS origin server. Once the IIS origin server receives a request for media, it will dynamically create cacheable virtual fragments from the video files and deliver the best content possible to each end user. The benefit of this virtual fragment approach is that the content owner only needs to manage complete files rather than thousands of pre-segmented content files.
“Smooth Streaming provides media companies with a better way to make full HD on the Web a reality. It offers code-free deployment and simplified content management for content creators and content delivery networks. For end users, the improved video viewing experience will bring the reliability and quality of HD television to their favorite video Web sites.”
