Watching HTML5 video on GNU Guix?

Watching HTML5 video on GNU Guix?

[znavko]

Hello! I've updated my system having now working Xfce4, this bug was fixed: https://issues.guix.gnu.org/issue/37342

But now I cannot watch HTML5 videos in IceCat 68.3.0esr (64-bit), cause it does not support one of formats video hosting is using.
It says: "In current time your browser does not support any of available video formats."

All those extensions in Icecat are disabled, so LibreJS, LibrifyJS, Searxes blocker - are disabled.

I have a question of how to use this part of the internet and work on GNU Guix simultaneously.

Hi,

I think I and Mark fixed that just a few days ago. Maybe try to run guix pull and update your system or the profile icecat is coming from. Otherwise, can you send us a URL that does not work for you, so we can try and fix it?

Thank you!

Trick answer, perhaps, but I watch all HTML videos with

  $ mpv URI…

even on other distributions.

On Guix System, it supports (libva) hardware acceleration, unlike 
any Web browser I've tried.

It's also just oodles more enjoyable & user-friendly than forcing 
a browser to be something it's not (slowly, badly, 
battery-destroyingly).

Unfortunately it doesn't support all sites, only those supported 
by youtube-dl.

Kind regards,

Those two video are working (cause youtube had converted them, I think).

On the other videos that are not displaying and often this is live streams (I think, youtube did not converted them to acceptable format)
these Javascript warnings with WebGL errors appear in terminal:

I can reproduce the problem; it seems that WebGL is now a required by
youtube when using Icecat 68? That's strange because the same video
plays fine in an older version of Icecat (but I have to reload the page
to get it playing).

Anyway, the problem seems to have more to do with Youtube than HTML5
playback in Icecat.  A random HTML5 video playback test site [0] may
help to convince you of such :-)

You could try enabling WebGL in your Icecat (disabled by default) by
visiting the "IceCat-specific privacy settings" of the Settings page and
checking "Enable WebGL".  That didn't work for me, as my driver seems
blacklisted by Mozilla.  I tried force enabling it with suggestions from
this page [1] but your link would still wouldn't be happy with my WebGL
support.

HTH,

Maxim

It's not blacklisted, it's blocked by mozilla's sandbox pplicy. In about:config you can change an option named sandbox.readpath.whitelist or similar. Set it to /gnu/store/ (with a trailing / which means recursively) to allow access to the store, where icecat can find its webgl libraries. Then restart the browser.

We should add that by default (or something more restrictive) but I don't know how.

Re: Watching HTML5 video on GNU Guix?

[znavko]

Yes, it works now! Thank you!
I did this:
1) Icecat -> Preferences -> Privacy & Security tab -> Icecat-specific privacy settings -> checked option Enable WebGL
2) about:config -> search by 'whitelist' -> security.sandbox.content.read_path_whitelist -> added a value: /gnu/store/
3) after Icecat restart video works https://www.youtube.com/watch?v=9K26GI4C3uY

Thank you!

PS: Youtube gives much knowledge and information for me in convenient way. I want to share with others this way. And it's policies to get personal data, history and interest gives to it and to the authors way to gain much money. Sorry, while other free and secure projects just put on their shoes, youtube runs on the millions computers.

Hello Znavko,

I'm happy that Julien found the solution to your problem.

This probably isn't useful.  It is a plugin for Qt, and Icecat does not
make use of Qt, AFAIK.
