Viewing screenshare of Windows user not working on Linux

(#649) Bug Needs triage desktop video
by RexSystem edited originally by @miniseekie on GitHub

Summary

When a user on windows shares their screen, I can see the preview, but the stream is just gray without audio when viewing from the Linux client. Seems to be the same issue as https://feedback.fluxer.com/p/391, that was closed for V2. Other Linux screenshares seem to work, and Windows users can view Linux shares as well. image image

Steps to reproduce

1.See a windows user screenshare 2.Click to view screenshare on Linux 3.Screenshare does not populate.

Environment

Version: V2 OS: Bazzite Browser: Both Client and Firefox Device: Desktop

I am also having similar issues - not entirely consistent, however, and sharing audio does not seem to work at all. It seems to be related to codecs and how different browsers utilize them. 2026-06-28T20:28:18.119Z INFO livekit.pub rtc/participant.go:2964 falling back to alternative video codec {"room": "guild_1516566176715505664_channel_1516566176715505714", "roomID": "RM_MTUkFSzzFNaj", "participant": "user_1516880839143587840_dropbear-acoustic", "participantID": "PA_PgWhnEvhSP68", "remote": false, "codec": "video/h264", "altCodec": "video/rtx", "enabledPublishCodecs": [{"mime": "video/rtx"}, {"mime": "audio/opus"}], "trackID": "TR_VSHpeTf7sU4mm8"}

This is all getting fixed very soon with a brand new voice architecture that I've been working on finalising (hence the silence). Expect something great very soon, along with the stable & canary clients being both made fully up to date with the latest code + fixes to connecting to self-hosted instances in the desktop app!

Cannot get audio working on any system, any browser. Using self hosted though @hampus-fluxer don't burn yourself out responding to us, we understand you are busy working. You build and the people will come, once you're at a comfortable place many of us will start contributing more too.
