I' ve read the following article:
How to secure smooth streaming using PlayReady DRM (Silverlight)
and did follow the steps in it, but I got stuck playing video.
Using Wowza Media Server 3, I tried both the key file way and server-api way, but I always got an error message on wowza server saying "PlayReadyEncryptor.encryptChunkCTR: java.lang.NullPointerException", and stuck in a "media error 3192" message when trying to play with Silverlight player.
I logged some messages at license server(PlayReady) and it showed that the license issuing functions correctly.
Are there anything I missed?
Thanks in advance,
