media-player

问题 I have been struggling with an issue with my media player windows phone (7) application. The problem is that I can't seem to implement playlists. What I want to do is play songs from the media library. This article seems pointless. I've tried getting into the SongCollection class and figure out how to create more of these things. It appears to be impossible (no constructor, can't cast it, can't inherit it). After that I tried getting an object on the process running the background audio agent

问题 In my project I have a DLL for some WPF/XAML controls that need to play some audio files. Now, with SoundPlayer I can make these audio files "Embedded Resources" of the DLL (that also contains the WPF controls). However, SoundPlayer has some severe limitation so I switched to MediaPlayer. Unfortunately, the MediaPlayer help page states that MediaPlayer can't work with resources. (I tried using Pack URIs anyway but this didn't work - at least none of the combinations I've tried.) So, for now,

Make your activity implement MediaPlayerControl and add unimplemented methods. Code is as below: I am using code from Api demos from here http://developer.android.com/resources/samples

问题 I'm trying to modify (extend) the FileInputStream class so that I can open an encrypted file and use the stream for MediaPlayer's setDataSource(FileDescriptor) . Problem is I don't know which method should be overridden to do the decryption inside the stream. I tried overriding all the read() methods, but the mediaPlayer doesn't seem to use them.
