that's because your hw doesn't support WebM VP9 as you noted in the post above.

btw, for those who change the webm settings, make a reminder to change them back once ff58 is released or a rumoured fix for this will be pushed out tomorrow.

Has nothing to do with hw; it is a software thing.

That's why the stream probably worked for you. If you looked at Stats for Nerds on the stream it's probably not coming across as VP9 since YouTube thinks your browser doesn't support it. Checking the stream, it's playing now for me coming across as VP9 so looks like YouTube pushed their fix out.

Tried a number of things to view the files - received a message - Your browser does not currently recognize any of the video formats available.
Provides a link but there's some form of feed and when clicking on the link it goes to the YouTube html page which shows HTML5 working.
Also my default webm setting are all true, tried media.mediasource.webm.enabled set false, no change.
Also tried enabling H264, no luck.
Other YouTube videos - no problem.

Try also, media.webm.enabled ----------------------> false.


The issue is that the feeds default, was webm, & that was failing in FF57.
Feed was also available as mp4.
So by disabling webm, it would revert to mp4.
As it is now, it seems the feed is in mp4.
So by disabling mp4, you might expect it to fall over to webm, but that is not the case, instead, simply failing.


Before the (supposed) change by YT, setting media.web.enabled to false, should have allowed the clip to play (as mp4).

That live stream is playing for me now using VP9 Webm, so YouTube changed something.

Tried the posted link and it all works now.
All four webm items in about:config set to true.
This on Linux Mint 18.2
