Jitsi Meet Screen Sharing with Ungoogled-Chromium

Jitsi Meet Screen Sharing with Ungoogled-Chromium

[Yasuaki Kudo]

Is there anyone here who uses Jitsi Meet to share screens from Guix?  Let me know!

At least in version 90 of chromium (third party, not a guix package), it used to work.

With the current ungoogled-chromium on Guix, the moment someone else connects to the Jitsi session, ungooogled-chromium dies with an 'aw, snap' message.

Those are not supported by GNU Guix and will be met with hostility,
because how dare you unfree scum!

Good thing that i ain't a bad person.. not part of GNU Guix to help! :p

Last time i tried it it worked out-of-the-box for me, i tested it now
again and also works without problem

GNU Guix (374fea0f3bc8035f626cb29e6045130df9ffdaf8) with
ungoogled-chromium-97.0.4692.71-1

Which was tested on the https://meet.jit.si instance.. Provide a
javascript console log which should have an explanation for this
failure.. My current hypothesis is that your chromium doesn't provide a
sufficient/sane TURN server and so jitsi crashes.

See
https://serverfault.com/questions/591837/how-does-chrome-webrtc-select-which-turn-server-to-use-if-multiple-options-are-g
on how to change the turn server.

..and to comply with GNU FSDG i have to tell you that using
non-ungoogled chromium and 3rd party repos is unethical as it most
likely
contains nonfree blobs which limit user freedom and contain
malware as such i am providing content of ~/.config/chromium in
attachment which should make your chromium more libre and i am also
encouraging you to use ungoogled-chromium.

EDIT: I missed the part with screensharing x.x .. on mentioned chromium
it starts printing:

[18990:23:0116/111829.036853:ERROR:webrtc_video_engine.cc(3446)] Absent
receive stream; ignoring clearing encoded frame sink for ssrc 0
[18990:12:0116/111836.246422:ERROR:video_stream_encoder.cc(1827)] Failed
to encode frame. Error code: -7
[18990:12:0116/111834.601625:ERROR:video_stream_encoder.cc(1149)] Failed
to initialize the encoder associated with codec type: VP8 (1)

in the console when i have screenshare and when someone joins and the
screen share changes to a black screen so i believe that this is a bug
due to the lack of sufficient VP8 codec.

Jacob, this style of communication is not acceptable on this mailing
list.

It is also not true.

Thank you much for your replies and I believe Jacob was just making a joke and I am in no way offended!   But thank you Ricardo 😄😄  I hope this bug gets fixed!

PS 
For various issues of conviction, of which Free Software is one, I believe we need to have open playful attitudes to the opposition (e.g. people who don't give a damn about software freedom)  a, if only to have more effective strategies by understanding them.   I was just watching this this morning https://youtu.be/Blz_Eu00Kbw 😄

It (starting/joining a jitsi meeting and sharing a screen/window/tab)
works for me with ungooogled-chromium version 92 from guix.  Newer
versions unfortunately don't which is probably related to this issue:

  https://issues.guix.gnu.org/50773

The last guix commit I've found with a working ungooogled-chromium is:

  08660f7c8880e30aecc05cd6302d2ccd715913e9

You can use guix timemachine to run it (see issue for an example).

A friend of mine runs a Jitsi instance on a private server, and we
sometimes have this issue because the Jitsi instance breaks for some
weird reason, and not because of the browser.

I suppose you tried with meet.jit.si already, and the other answers to
this thread are very useful, but I thought I'd mention my experience for
the record.

 From my experience and assisting maintenance of jitsi it's very stable
in terms of production runtime so i would say that your friend
misconfigured the deployment.

Also i think that it's very clear that the screen share fails due to the
lack of VP8 codec support based on provided terminal output.

Just a follow up.  This issue appears to be fixed in the latest
version.  See also: https://issues.guix.gnu.org/53301

I can happily confirm that the problem is gone!  I can see my Guix screen from my Iphone via Jitsi!!

Thank you so much!!  I still have to deal with the fact that screen sharing itself has lots of bugs or missing features but that is probably because I use wayland (as opposed to X) 😅
