Toggling Tile View changes aspect ratio / crop of other participants video

Description:

When toggling the tile view, the apsect ratio of other participants video is changed in their view regardless of their setting of tile view or speaker view, resulting in a cropped image.

Steps to reproduce:

1. Join any jitsi call with at least two participants
2. have one participant toggle tile view on and off while other participant watching their own video aspect ratio
3. user who is doing nothing experiences changes in their video

Expected behavior:

Own video stays the same when other participants change their view settings.

Actual behavior:

Own video gets cropped when other participants toggling tile view.

again, this is happening on my view while the other person is changing their settings. I don’t really get why the resolution for my view has to change at all as I’m not doing anything.

Yes, that is the intended behavior of this new feature. We do not want to use resources (cpu/bandwidth) more than they are needed on the client machines. So the participants send resolution will now be determined based on how they are viewed by the other participants in the call. If a remote participant is viewing you in speaker view at a full 720p, only then your client will be sending 720p.

I’m seeing this on any regular meeting on meet.jit.si

The problem ist not a change in resolution but a change in aspect ratio of the image I am viewing while someone else is toggling their tile view. So if another participant is switchen to tile view the image I am seeing of my own video is cropped in. I want my picture to be cropped the same way regardless of what anyone is changing in their preferences. Hope this clears things up.
