WPEWebKit has the skeleton code to support plugging in different DRM systems. Currently we know it can support PlayReady
and Widevine, but obtaining those libraries / SDKs is the responsibility of the integrator due to licensing issues we
have with these systems.

This is due to some desync between the WPEWebKit on GitHub and the upstream repository that we are in the process of
addressing. The one on GitHub is being used with an external system that integrates Widevine, whereas the one upstream
is only used with ClearKey. The upstream can work with Widevine as well, but that code is not provided for reasons
mostly due to licensing, and partly due to some desync.

No, you would need third party libraries from the DRM provider for this to work. The code you see in these repos is just
glue. But yes, if you already have a DRM library licensed for Widevine/PlayReady at least, it can be made to work inside
WebKit.
