1266195 - Re-re-enable using Adobe GMP for decoding when system H.264/AAC codecs not available

Status: RESOLVED INVALID

(Core :: Audio/Video: Playback, defect, P3)

Description

[Chris Peterson [:cpeterson]]

+++ This bug was initially created as a clone of Bug #1250766 +++

After Adobe fixes the CDM's Pentium 4 and SSE2 crashes, we can re-enable using the Adobe GMP for decoding when system H.264/AAC codecs are unavailable.

This means Windows XP, Windows Vista, and N/KN Windows variants without the Media Feature Packs installed will be able to decode and play MP4/H.264/AAC video.

We can enable this once we require SSE2 to run Firefox.

There appears to an issue with Pentium 4 CPUs which still needs to be investigated. P4 CPUs support SSE2.

Mass change P2 -> P3

Per bug 1288582, we will no longer enable Adobe CDM on WinXP. But this bug is still valid for N/KN editions.

We no longer have access to an Adobe CDM, so closing this.
