Screensharing frame rate slow since my last update of bbb (or firefox)

[Gerald Lang]

Hi all,

since I had installed the update - I think it was in first part of June - the frame rate of screen sharing seems a little bit poor.

Let me explain, what I mean:

After I had installed bigbluebutton with bbb-install.sh the first time, all things worked as expexted!

You did and do a great work! Thanks!

And I was really surprised, that I was able to stream a movie or another webcam via screensharing in a very good quality, not with Chrome, but with Firefox.

After my first update it isn't working anymore as expected. Camera or movies stutter and are no longer displayed smoothly.

Why it is important for me? Well, we use this in our webinars with a second camera to show the participants of the webinar more details in the center of bbb. In this setting the moderator is always visible on the top and noone must change there view.

Here my questions:

Did you changed anything in screensharing or do you know if Firefox changed something?

Are there any settings or codecs which changed or which I have to change?

Thank you very much for any help!

I hope this is in the right forum.

Regards,
Gerald
