            Bug ID: 25966
           Summary: Use ArrayBufferView and ArrayBuffer instead of
                    Uint8Array in APIs
           Product: HTML WG

The EME APIs currently use Uint8Array for all binary data. Uint8Array is just a
subclass of ArrayBufferView, and I don't think there is a reason to require
8-bit formatting.

For data provided to the application, we might need to use an ArrayBuffer.

MSE's appendBuffer() accepts either ArrayBuffer or ArrayBufferView [1]. I'm not
sure whether EME needs to support both.
