I am developing a Miracast sink app following the UWP Miracast API documentation that must support content protection using HDCP.
Currently, projection of unprotected content works fine. However, the API does not seem to enable HDCP for the Miracast Session and I couldn't find anywhere in the documentation a way to do this.
As stated in the output report of dxdiag my hardware supports Miracast with HDCP:
Miracast: Available, with HDCP
Additionally, sniffing the RTSP packets using Wireshark, the HDCP related parameter in the M3 response is wfd_content_protection: none when it would be wfd_content_protection: HDCP2.1 if HDCP was enabled.
How do I enable it for the Miracast session? Is this a limitation of the UWP API? Or should content protection be enabled through a different API?
Any help is welcome
