The current spec text on that topic was added in response to https://www.w3.org/Bugs/Public/show_bug.cgi?id=21155 . It seems that the position of the spec is that the interaction with canvas, the Web Audio API and the like depends on the Robustness & Compliance provisions each CDM is subject to instead of depending on EME itself. -- Henri Sivonen hsivonen@hsivonen.fi https://hsivonen.fi/
