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.

[Chris Peterson [:cpeterson]]

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.

[JackTail]

Hope I am helping, new to submitting bugs like this.

My original testing was done using the DASH.js framework, https://github.com/Dash-Industry-Forum/dash.js/wiki
Self hosted works in Chrome and IE but not FireFox (Nightly build 42.0a1).

Hosted test players (of which, none work with live stream for me, even in Chrome) http://dashif.org/reference/players/javascript/index.html

Shows like it is about to play, but no video or audio. Does show time data from my Wowza server.

I would provide a test link, but streams on my server are not 24/7. Though I can set one up for demo if needed, the demo ones from Unified Streaming kind of work, but stop after 5 seconds in Chrome, no play at all in FireFox. I am not sure if this is only my end or not.

[Jean-Yves Avenard [:jya]]

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

We are now confident enough that MediaSource is usable by all

Release Note Request (optional, but appreciated)
[Why is this notable]: more HTML5 video for everyone

[Links (documentation, blog post, etc)]:

Comment 13

[Sylvestre Ledru [:Sylvestre]]

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.

Comment 14

[Roque]

Will the remotion of the whitelist apply for Linux too?

Comment 15

[Jean-Yves Avenard [:jya]]

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

Comment 16

[Roque]

Thanks.

Comment 17

[Roque]

Do you know why MSE is still not enabled in Linux? Youtube.com/html5 says so...

Comment 18

[Chris Peterson [:cpeterson]]

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

Comment 19

[Roque]

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!

MSE is only enabled in 43 beta on Linux.
Both MP4 and webm

Comment 22

[Jean-Yves Avenard [:jya]]

In 42; for now set media.mediasource.enabled = true and media.mediasource.webm = true

Comment 23

[Chris Peterson [:cpeterson]]

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.

Comment 24

[Roque]

Thank you Jean-Yves and Chris Peterson. If i set those two values to true, will I have any issue when updating to 43?

You should have no problems updating to 43.

Comment 26

[Jean-Yves Avenard [:jya]]

Just use beta now :)

Comment 27

[Roque]

Thanks.

Comment 28

[Roque]

Do you know if 43 on Linux is still having enabled Webm and MP4? Thanks.

Comment 29

[Chris Peterson [:cpeterson]]

(In reply to Roque from comment #28)

Yes. Firefox 43 on Linux will support MSE with WebM and, if you have ffmpeg installed, also MP4.

Comment 30

[Roque]

Thanks Chris, great news, I have ubuntu 14.04, I think it has ffmpeg installed by default.

Comment 31

[Masatoshi Kimura [:emk]]

Did you find this bug in the regression range? MSE was enabled on YouTube even before this bug.

Comment 32

[Jean-Yves Avenard [:jya]]

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.

Comment 33

[Virtual_ManPL [:Virtual] 🇵🇱 - (please needinfo? me - so I will see your comment/reply/question/etc.)]

Yes. Looks like it's other issue.
