We plan to enable MSE for all websites in Nightly 42.
Tested with latest Nightly, works well with VOD but live streams stop after about 20 seconds. Tests were done using the BitDASH player found at http://www.dash-player.com/demo/manifest-test/ with Wowza Streaming Engine as the CDN backend. As well as other player in my own test environment.
Thanks for testing, JackTail. Bitmovin's live stream demo gets stuck rebuffering for me, too: http://www.dash-player.com/demo/live-streaming-dvr/ I filed bug 1186136 to track that issue.
Are those live streams? We have an issue with the DASH-IF player with live streams. Though at this stage I haven't fully confirmed if the issue is on our hand, or its dash.js

Comment on attachment 8641401 [details] [diff] [review] [MSE] P1. Remove whitelist. Review of attachment 8641401 [details] [diff] [review]: ----------------------------------------------------------------- \o/
Release Note Request (optional, but appreciated) [Why is this notable]: more HTML5 video for everyone [Suggested wording]: Media Source Extension for HTML5 video enabled on all sites [Links (documentation, blog post, etc)]:
Added to the release notes with "Media Source Extension for HTML5 video available for all sites" as wording. I will update the item with a link to the docs when available.
Will the remotion of the whitelist apply for Linux too?
There is no whitelist in 42 regardless of the platform. However, Linux in 42 only has support for MSE with webm. MSE with MP4 is enabled in 43 only
Do you know why MSE is still not enabled in Linux? Youtube.com/html5 says so...
Roque, MSE should be enabled on Linux. youtube.com/html5 should show that "Media Source Extensions" and "MSE & WebM VP9" are enabled, but not necessarily "MSE & H.264". If they are not, please file a new bug report including your browser's about:support troubleshooting information. Instructions are available here: https://support.mozilla.org/kb/use-troubleshooting-information-page-fix-firefox
Chris, MSE and MSE & WEbM VP9 aren't enabled, I tried it in another computer with Ubuntu and its the same... Should I report?

If you are using Firefox 42 or later, please file a bug report. WebM VP9 should have been enabled on Linux in Firefox 42 by bug 1190970. In the bug report, please post your browser's about:support information, as described in this KB article: https://support.mozilla.org/kb/use-troubleshooting-information-page-fix-firefox Thanks!

In 42; for now set media.mediasource.enabled = true and media.mediasource.webm = true
Jean-Yves is correct. I saw that MSE had been uplifted to Aurora 42 in bug 1190970 comment 37, but I did not see that it was later disabled by bug 1200834.
Thank you Jean-Yves and Chris Peterson. If i set those two values to true, will I have any issue when updating to 43?

Just use beta now :)
Do you know if 43 on Linux is still having enabled Webm and MP4? Thanks.
(In reply to Roque from comment #28) > Do you know if 43 on Linux is still having enabled Webm and MP4? Thanks. Yes. Firefox 43 on Linux will support MSE with WebM and, if you have ffmpeg installed, also MP4.
Thanks Chris, great news, I have ubuntu 14.04, I think it has ffmpeg installed by default.
Did you find this bug in the regression range? MSE was enabled on YouTube even before this bug.
Very unlikely this bug caused the regression seeing that YouTube was *never* impacted by the whitelist: in fact this bug was to allow other sites than YouTube to use MSE.
Yes. Looks like it's other issue.
