1978428 - Implement the enum MediaKeySessionClosedReason

Status: RESOLVED FIXED

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

Description

[Alastor Wu [:alwu]]

MediaKeySessionClosedReason is an enum to indicate why the media key session is closed, so that websites can better handle this in their player to avoid playback error.

This was introduced in the EME spec 4 years ago, and Chromium shipped it in the same year. Our standard position ticket marks this as non-harmful.

Attachment: Bug 1978428 - part1 : implement MediaKeySessionClosedReason and return `closed-by-application` for `closed`.

The default is returning closed-by-application for close per the spec [1]. We
will implement returning other reasons in bug 1978434.
