            Bug ID: 21155
           Summary: EME should be explicit about its relationship with Web
                    Platform APIs that allow video frames are audio
                    samples to be extracted from an HTMLMediaElement

The purpose of EME suggests limiting the availability of video frames or audio
samples to JavaScript programs. If it is the intent of EME to limit the
availability, the specification should define how HTMLMediaElements with
non-null keys property interact with other Web Platform APIs that normally
allow video frames or audio samples to be extracted from an HTMLMediaElements.

If the intent is not to to make a non-null keys property to have an effect on
how HTMLMediaElements interact with APIs that allow video frames or audio
samples to be extracted from an HTMLMediaElement, there should be an
informative note stating this explicitly, because the absence of requirements
would be surprising given the purpose of EME.
