if you want quick response

What steps will reproduce the problem?
1. I have added code to restart the camera and preview in
NgnProxyVideoProducer.java with a new resolution when the user clicks on a
button while in a video call.
2. I see the changes on the video producer side. But the video preview gets
frozen on the video consumer side.
3. What changes need to be made in the video consumer to support dynamic
framesize change?

What is the expected output? What do you see instead?
I would like to see dynamic framesize changes in effect.

What version of the product are you using? On what operating system?
Currently, framesize changes are seen in the preview of the produces, but video
freezes on the consumer end.

Please provide any additional information below.

Is it even worth it going this path?

Start with NgnProxyVideoProducer.java and trace the corresponding video consumer path for the restart and preview flow. Reproduce the resolution change during a video call, then identify the consumer-side behavior needed so the new frame size takes effect without freezing; no test file is named in the issue.
