1914558 - [wmfme] PlayReady clearlead detection is not accurate

Status: RESOLVED FIXED

(Core :: Audio/Video: Playback, task, P1)

Description

[Alastor Wu [:alwu]]

We found out a situation where Firefox doesn't report the clearlead result correctly. However, on the same device, Edge can stream 4K, which means that device should have the clearlead support, and Firefox should report the support as well.

Attachment: Bug 1914558 - part1 : only set decoder subsystem for Widevine.

By our testing, the decoder subsystem feature [1] is not mandatory
required by PlayReady, it's only mandatory required by Widevine.
