playreadyproxy (prp)

notes

• this is an edge extension based on widevineproxy that has been modified to work with playready drm
• it is still early in development so some features are missing (local cdm support) and you may encounter bugs
• the extension only works with windows+edge, but the api server can be run from any machine
• for the sake of this guide, I will assume you are running both the api server and the extension from the same windows machine

requirements

• git
• python
• a playready cdm
