Silverlight 5 has undergone few changes in the media stack: 

    • Better Battery Management:
Less battery when playing media. Plus, no screensaver in the full-screen mode. 
    • Remote Control Support:
Now you can control the media being played in Silverlight 5 using a remote control. This feature is currently not available in the Beta. [...]

As you’d expect, Silverlight can already play audio and has been able to since day one via the MediaElement class which doubles up for also playing video.

If I remember rightly, audio support is for mp3, WMA7, 8 and 9 and also for AAC but does not include WAV files. MediaElement is pretty easy to use but if you’ve got requirements like; 

    1. Multiple media elements playing back on loops 
    2. Multiple media elements playing back at different volumes 
    3. Multiple media elements playing back at different pitches

Last week I posted a sample voice recorder on CodeProject. The application would buffer the entire recording in memory before writing it to a file. A rather astute reader asked me what would happen if the user let the recording go long enough to fill up memory. The answer to that question is the application would crash due to an exception being trhown when it fails to allocate more memory and all of the recordingwould be lost.

Nick Gravelyn talks about the changes in MediaPlayer, the interface for playing music on Windows Phone, that can affect your applications.

The short is that you are no longer allowed to set the Volume or IsMuted properties when the active media source is the Zune media library and any time you switch between library music and title music, you must reset any properties on MediaPlayer you care about. These changes were made to ensure applications didn’t alter the user’s music playback experience in a way that the native Zune media player cannot reverse (there is no UI in the Zune media player for music-specific volume or a mute control).

Den Delimarsky demonstrates how to play existing media content on WP7 using the MediaElement control.

Ultimately, this article started from a simple question - how is it possible to play a media file on Windows Phone 7? There are two ways to play existing media content. The developer has to either use the system player (given that the media content is stored in the media library), or use the MediaElement control.

MediaElement might be a bit tricky, but it's not that hard as it seems.

In this article, Den Delimarsky is explaining where exactly the data is stored when the user captures media content.

In the last post, we showed you how to capture a picture in your application when hooking to the ‘extras’ menu on windows phone. Once you have manipulated the picture you will want to save it in the media library. In this post we will walk you through the steps to do that.
