Very odd. I am unable to reproduce this. Have you seen this @jallamsetty1 ?

[jallamsetty1]

Nope and I am unable to repro this myself. @mkraetke Can you please share the log that shows what getUserMedia constraints are being passed?

[jallamsetty1]

Alternately, you can execute the following command on the browser console when you are in a conference and share the output with us.

APP.store.getState()['features/base/config'].constraints

I made a screenshot. Firefox does not copy the entire message, so hope this helps:

[saghul]

Ha, so width is not defined? You marked the box for "The problem is reproducible on meet.jit.si" but our config is different than what you showed. Where exactly are you testing?

[mkraetke]

Sorry, this was my fault. We're using jitsi self-hosted on our server.

Can you please share your config.js file?
