Hi,

I've noticed an issue in IE 11 when you choose a smaller display size than capture size the image is upside down.

This issue happens even with your demo page

It doesn't affect IE 9 or 10.

Upside down? That's really bizarre. WebcamJS isn't doing anything with the image that would cause that. Can you try these other libraries and see if they have the problem in IE 11 as well?

Try this Flash Webcam test page: https://www.onlinemictest.com/webcam-test-in-adobe-flash
Try jQuery Webcam: http://www.xarg.org/project/jquery-webcam-plugin/
Try JpegCamera: https://github.com/amw/jpeg_camera

I'm trying to determine if the upside down bug is in WebcamJS, or something strange with your Flash plugin in IE 11.

Hi,

I've checked out those libraries' demo pages:

Here's screenshots of them all:

And here's screenshots of your demo pages
