HTML 5 videos won't play Topic is solved

[evcco]

Check also the settings in Preferences | Content -> Video & see if messing with them might change anything?

SUCCESS!

Turning off "Use MSE asynchronously" and turning on "Enable MSE for WebM video" did the trick.
"MSE & WebM VP9" support on Youtube is now activated, which seems to have been the culprit.

Only downside, however, is that it appears I can no longer let videos load to completion before playing them, which is my preference for longer vids.
A small quibble, though.

Thanks to everyone - PM 27 is not quite dead yet!

Would this about:config setting help? media.block-play-until-visible

[evcco]

Unfortunately this doesn't seem to work. But thanks anyways!

Again, not a big deal. I think there are some add-ons that will do this if I really want.
And, of course, proxy sites as well.

One add-on that might help, and which I've used for years, is YouTube High Definition v. 52.0.3.

[DoctorM]

Running Version: 27.9.4 (64-bit). Tried some of the new YouTube Free Movies and getting "Your Browser Currently Does Not Recognize..."

Disabled the "Use MSE asynchronously" and turned on "Enable MSE for WebM video". All six HTML5 variants are now listed as supported by browser on YouTube but the videos still give the same error.

Here's one of those links: https://www.youtube.com/watch?v=jgOT-TJQ5AE

Edit: Tested on fresh install of v28.2.1 64-bit. Same result.

Same here. (PM 28.2.1 w/new profi8le, Win 7 x86)

YT-html5-pm28.2.1.png

It appears to be this way for all 'Free to watch' films from the YouTube Movies channel
(though not for the few "Free to watch" that are from other channels).

For info, it happens whether logged in or out, and with "new" YouTube no less than with "classic" YouTube.

Don't know if this is useful, but: Error console.

Code: Select all

Error: Error: Permission denied to access object

It can't work since the video requires DRM.

Thanks gepus, that's it.

It did play for me on Basilisk, with a couple of settings adjustments in about:config.


If you'd like to try, here's what to do:

- FIRST -
Modify the value for the setting: media.gmp-manager.url so that the reference to " 55.0 " in the string is changed to " 60.0 ".
This will ensure that you get the necessary version of Widevine (read more here.).

1. To do this, first paste the following into the address bar, then hit enter:

Code: Select all

about:config?filter=media.gmp-manager.url

2. Right-click on the setting, and from the context menu select "Modify".
Then paste the value below into the box that will pop up, and click "OK":

Code: Select all

https://aus5.mozilla.org/update/3/GMP/60.0/%BUILD_ID%/%BUILD_TARGET%/%LOCALE%/%CHANNEL%/%OS_VERSION%/  %DISTRIBUTION%/%DISTRIBUTION_VERSION%/update.xml

3. Now open Basilisk's Preferences to Content (about:preferences#content) and tick the box next to "Play DRM content". This will make the Widevine plugin download and install.

4. Open the add-ons manager (about:addons, Ctrl+Shift+A), select Plugins and check that Widevine is there. Click the blue link that says 'More' to check the version - it should be version 1.4.8.1008 (not 1.4.8.903).


- SECOND -
Change the value of Basilisk's hard-coded UA override for YouTube so that it refers to Firefox 60.0 (or higher), rather than Firefox 42.0.

1. In order to do this, paste the following into the address bar; hit Enter:

Code: Select all

about:config?filter=general.useragent.override.youtube.com

2. Now modify the value of the setting general.useragent.override.youtube.com to the following string (paste it in the popup box):

Code: Select all

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:60.0) Gecko/20100101 Firefox/60.0 Basilisk/52.9.2018.11.07

Now the video should play in Basilisk.

Google Widevine requires in-browser DRM (using Encrypted Media Extensions).
We do not and will not support EME or in-browser DRM in Pale Moon, now or in the future.

Is that something Pale Moon doesn't/won't support?

Edit: You type and submit faster than I do Barryh2.

Yep, doesn't & won't. Not now, not ever. If you need DRM you need to use a different browser.

[DoctorM]

It's okay. I have a smart TV that can do the job. I was just surprised there was something the browser couldn't do.

[Nigaikaze]

I was just surprised there was something the browser couldn't do.

To be accurate, it's a "won't do" rather than a "couldn't do," because this is a deliberate choice that the developers made.

[DoctorM]

It's not a bug, it's a feature.

[therube]

but does [play] in waterfox and firefox wierd

DRM

Ah, so that's why I didn't get playback in FF 63.
I use the DRM-free versions of FF (EMEfree).

[illiad]

well my problem is I am in UK, so most of the above yt vids say "The uploader has not made this video available in your country. "

does that mean it works or not??

...

it means you can't verify it with these particular videos, because of regional restrictions. You'll have to find other videos that are available to you.

You could also use a VPN service that enables you to surf as if you were in various countries.
