Package: firefox
Version: 122.0-1
Severity: important
X-Debbugs-Cc: daniele-...@gobbetti.name

Dear Maintainer,

as I updated to firefox 122 I could see that sending video in videoconferences 
does not work anymore.

The local sound can be heard on the other side of the connection, but the video 
stream is simply not visible,
this is true both for webcam as for screen sharing.
The local browser window shows everything correctly.

I could reproduce the issue also using janus "echo test" on their website 
( https://janus.conf.meetecho.com/demos/echotest.html ) and by starting firefox 
in "safe mode".
Additionally I tried changing the libavcodec60 package and installing the 
-extra version, to no avail.

I tried firefox 122 from mozilla ( from their tar.bzip2, not from their deb 
repository ) and it works.
Debian's packaged Firefox 121 wasn't affected by this problem.

Best Regards,
Daniele Gobbetti
