Observed behaviour
Except when VP8 is selected (which correctly uses libvpx), Fluxer always uses OpenH264 on my system. This is even when I have the OpenH264 option disabled.
Additionally, the attached error appears in the terminal output when starting a screenshare, which I assume is related to the issue.
I suspect the issue is specific to Linux so I've added that to the title of this report. Please only deny if you are unable to reproduce on Linux.
Reproduction steps
- (Optional) Start Fluxer Canary from the terminal (or use journalctl to find the terminal output later)
- Select any codec other than VP8
- Start a screenshare
- Look at Stats for Nerds
