How to get resize events in Chrome desktopCapture

Question

I'm using Chrome's desktopCapture in an extension and I have an issue that I'm attempting to work around. Any help would be greatly appreciated. I cannot post any source, but the chrome extension itself is commonly available and used on the web.

Issue

The issue is with resize / dimension changes that may occur while desktopCapture is capturing / streaming to the server. These changes can often occur seemingly too fast for my client to handle, causing the client application to crash.

Solution

I'd like to get some event or notification when the capturing end detects a resize of the area being captured; for instance a window which has been clicked and is being dragged to resize it.

An alternative would be if the event.data can be queried for width / height.

Research

I've google'd and searched the chrome / webrtc issues; I've come up empty thus far. There really isn't any good implementation information available from what I've found.

Going through the Chromium codebase is not an option for me; I am not a C/C++ developer.

What I would like from You

If you have experience with the desktopCapture offering, please share what you know. If you don't have any idea what I'm asking or have nothing constructive to add, please ignore this and move on.

Commentary

As of July 17th 2015, it would appear that there is a bug or missing support for resize events in Chromes desktopCapture extension. I will file an enhancement request with them and see where that goes. It probably won't help that "normal" WebRTC streams aren't "expected" to change dimensions during streaming and thus it is not handled.

Answer 1

Attach the captured stream to a video element and listen for the onresize (onsize?) event. Should also work for hidden elements if you don't want to display something at the capturing end.
