1181454 - [EME] requestMediaKeySystemAccess broken with e10s on

Status: RESOLVED FIXED

(Core :: Audio/Video, defect, P1)

Description

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

navigatio.requestMediaKeySystemAccess() always rejects with an exception with message "NotSupportedError: Gave up while waiting for a CDM update", and we always see a "Nightly is installing components required to play audio or video on this page" notification box drop down from chrome.

STR:
1. Enable e10s
2. Open http://drmtest2.adobe.com/HTML5AAXSPlayer/2/mse-access/
3. Press "play" button.

Observed result: video doesn't play, notification box drops down.

Expected result: video plays

ClearKey works fine, it's just Adobe EME that appears broken.

AdobePluginFileExists() is failing at the line:

nsresult rv = NS_GetSpecialDirectory(NS_APP_USER_PROFILE_50_DIR, getter_AddRefs(path));

I guess NS_GetSpecialDirectory() doesn't work with e10s on. :(

Attachment: Patch: Work around problem

Work around the problem until the longer term fix is done; remoting the MediaKeySystemAccessManager to the chrome process.

This will get Nightly working again ASAP.

I'm running inbounds with this patch with e10s on and no video plays.  Is this patch supposed to produce a video or am I misunderstanding the problem?
