Playing media from another source type

Hello everyone, I want to play audio and video in my QML application. The problem is: I’m handling protected data (mp3, avi etc.). Therefore I’m writing those files to an encrypted container file. I know I’ll have to subclass QIODevice and implement my own read, seek, write etc… Unfortunately, I definitely have to use encrypted files. So, how do I play these files in QML’s MediaPlayer?
