I currently met some problems when developing video streaming on Windows Phone.
When we try to play video sample for Windows Phone, the video worked fine but when i try protect my stream video follow link ([https://www.wowza.com/docs/how-to-secure-smooth-streaming-using-playready-drm-silverlight](https://www.wowza.com/docs/how-to-secure-smooth-streaming-using-playready-drm-silverlight)), i have file key of video in folder keys, add module “onHTTPSmoothStreamingPlayReadyCreateVOD” and i stil cant do this work. In my opinion the document is too poverty and i dont understand how it work. I also consider that Do i need buy EZDRM to protect smoothstreaming ??? or can i protect stream with free option
