Steps to reproduce:
0. Get ungoogled-chromium
1. Open a call on jitsi e.g. https://jit.si/ILoveKreyren2Much
2. Start a screenshare
3. Join the call from a different browser and expect the sc reenshare to malfunction either with tab crashing with "Aw, snap" or the screen share changing on black screen and chromium printing this to the console:
[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)
I assume that we need to include VP8 codec

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.

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. -Yasu
