25966 2014-06-03 21:27:28 +0000 Use ArrayBufferView and ArrayBuffer instead of Uint8Array in APIs 2014-10-20 18:30:14 +0000 1 1 1 Unclassified HTML WG Encrypted Media Extensions unspecified All All RESOLVED FIXED P3 normal --- 23369 1 ddorwin ddorwin acolwell annevk d jdsmith mike public-html-media watsonm public-html-bugzilla oldest_to_newest 107220 0 ddorwin 2014-06-03 21:27:28 +0000 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.

ArrayBufferView adds the ability to view data with an offset. For SourceBuffer, that seems useful. It's harder to see where it would be of use in EME. 107940 2 ddorwin 2014-06-17 15:18:21 +0000 Notes from telecon today: Anne pointed us to WebIDL bug 23369. Adrian proposed that EME methods should accept either. That allows a view of a buffer to be passed as well as an ArrayBuffer to be passed without creating a view. Event attributes should be an ArrayBuffer. 108299 3 watsonm 2014-06-24 21:38:49 +0000 https://dvcs.w3.org/hg/html-media/rev/b8e333b8510c 112757 4 ddorwin 2014-10-06 17:56:38 +0000 Bug 23369 has been resolved by, among other things, adding: typedef (ArrayBufferData or ArrayBuffer) BufferSource; I'm reopening this to track updating the spec to use the typedef for method parameters. http://heycam.github.io/webidl/#common-BufferSource http://heycam.github.io/webidl/#idl-buffer-source-types 113483 5 ddorwin 2014-10-20 18:22:03 +0000 (In reply to David Dorwin from comment #4) > Bug 23369 has been resolved by, among other things, adding: > typedef (ArrayBufferData or ArrayBuffer) BufferSource; This work had been blocked by a typo in this text (bug 27110).
