            Bug ID: 197433
           Summary: Unprefixed EME with "com.apple.fps.1_0" fails with
                    "The operation is not supported."
           Product: WebKit
           Version: Safari 12
          Hardware: Unspecified
                OS: macOS 10.14
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Media
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: joeyparrish at google.com

Running the following in the Safari debugger on localhost (a secure origin) fails with "The operation is not supported":

minimalConfig = {videoCapabilities: [{contentType: 'video/mp4; codecs="avc1.42E01E"'}]};
mk = await navigator.requestMediaKeySystemAccess('com.apple.fps.1_0', [minimalConfig]);

But the equivalent calls in the prefixed API works fine:

WebKitMediaKeys.isTypeSupported('com.apple.fps.1_0', 'video/mp4; codecs="avc1.42E01E"')
mk = new WebKitMediaKeys('com.apple.fps.1_0');

As does the unprefixed API with clearkey:

minimalConfig = {videoCapabilities: [{contentType: 'video/mp4; codecs="avc1.42E01E"'}]};
mk = await navigator.requestMediaKeySystemAccess('org.w3.clearkey', [minimalConfig]);

I'm running macOS Mojave and Safari 12.1, so this should work, right?  It's not clear from the error what is wrong or missing.

Has the key system ID changed?  Are there docs on this somewhere that I've missed?
