1257726 - [EME] Parse encryption data in WebM

Status: RESOLVED FIXED

(Core :: Audio/Video: Playback, defect, P2)

Description

[Chris Pearce [:cpearce (Not reading bugmail)]]

To support WebM ClearKey EME, we need to add support for parsing the EME/encryption stuff inside WebM files to libnestegg.

This entails parsing the EME "initData", and ensuring we parse subsample keyId/IV info for each sample. We need a way to surface this information to the caller of libnestegg, and we need appropriate test for this.

Attachment: MozReview Request: Handle clearkey encrypted WebMs. Requesting feedback: r?cpearce

Make sure an encrypted event is created for WebMs. Handle encrypted WebM
streams for the clearkey case.
