Add support for Certurl element in ContentProtection to enable FairPlay DRM

[tobbee]

The CPS group of DASH-IF has in DASH-IF-IOPv5.0.0-Part6 draft 3 defined a new Certurl element useful for some DRM systems, especially FairPlay

In livesim2, this should be connected to CPIX elements and published accordingly with FairPlay DRM ContentProtection element

5.4 Certificate acquisition URL

One or more Certurl elements may be added under the ContentProtection descriptor. It contains the URL for a license server allowing to retrieve a certificate in the format specific to the DRM system that is described by the ContentProtection descriptor. It has the optional attribute @certType that is a string describing the certificate type served by this license server. The meaning of this attribute is DRM specific.
When present, it is expected that the device first use the URL under this element for retrieving the certificate. This certificate can then be used in a DRM specific manner for requesting a license using the URL provided under one Authzurl element.

@avelad Great that you found this topic and got it implemented in shaka-player! In the DASH-IF slack, the conversation with you are no longer visible.
