With a couple of patches from @rmader in libwebrtc we got camera rotation fixed on the PinephonePro, and webrtc based services like Whereby just work!
Coming soon in debian packages and full images :)
@capyloon Here are the patches: https://bugzilla.mozilla.org/show_bug.cgi?id=1843786
We can hopefully upstream the #webrtc patches so all variants of #Firefox and #Chromium have good camera support on #LinuxMobile
