Can shaka player read license proxy uri from the playlist?

Is there any way for shaka player to read the uri of the license proxy server from the playlist/manifest itself?

Currently I am hardcoding the license proxy server uri in the player config as per instructions here - https://shaka-player-demo.appspot.com/docs/api/tutorial-drm-config.html, but that doesn’t work for me because the license proxy server uri changes for every playlist in my system so I want my users to be able to play DRM protected content just by adding the manifest url and without having to add license server URI in the shaka player config.

If there is absolutely no way to accomplish above, I can probably add a custom field in the ContentProtection tag of the manifest, could you provide some instructions on how I can read a custom attribute from the ContentProtection tag in the manifest and make it available to the getNetworkingEngine().registerRequestFilter callback so that I can forward it to the license proxy server.

Thanks!

@TheModMaker also gave an example in an email thread recently: https://groups.google.com/d/msg/shaka-player-users/fVDlZABXMF4/3b1NnHofAQAJ

@aaani feel free to take a look.
