How to enable HDCP content protection through UWP Miracast API?

Gabriel Remus Linck Duarte 0

Greetings!

I am developing a Miracast sink app following the UWP Miracast API documentation. Currently, standard projection of unprotected content works fine.

However, the API does not seem to enable HDCP (for Netflix, Prime etc) in the Miracast Session and I couldn't find in the documentation any way to do this. My hardware supports Miracast with HDCP as stated in the DxDiag report.

How do I turn it on for the session? Is this a limitation of the UWP API? Or must content protection be enabled through a different API?

Thanks.

Hi @Gabriel Remus Linck Duarte ，

Welcome to Microsoft Q&A!

Can using PlayReady DRM meet your needs? PlayReady DRM allows you to play content over Miracast output as soon as HDCP 2.0 or later is engaged.

Here is the official document.

Thank you.

Hello @Junjie Zhu - MSFT

I've already stumbled upon the PlayReady DRM page, alongside its C# samples (https://github.com/microsoft/Windows-universal-samples/tree/main/Samples/PlayReady), but did not understand how to implement Miracast playback specifically via its API.

I'm unable to initialize a wfd_content_protection enabled Miracast session, so the source device never sends encrypted content to begin with.

Could you please provide an example for a PlayReady/HDCP enabled Miracast sink?

Hi @Gabriel Remus Linck Duarte ，

There are currently no relevant code samples in the official documentation. I need to check with the team how to use Miracast sink in PlayReady.
