Zoom or guvcview cannot use the resulting video stream

Hi @denys-potapov ,

Great work, so nicely done, bravo! 👍 👍 👍

I was not able to feed Zoom or guvcview with this video stream though. As I understand, application's general assumption is that they are given a device, which allows them to select the frame format properties as they wish. Being not able to tweak the video device, they think it is broken. This is a very stupid state of fact, that we nonetheless must obey. Do you have any further idea regarding this?

It's been a while, sinse I've touched a code. But from fast googling:

1. There is a special lib for making fake webcams - https://medium.com/@candres.alv/image-filters-for-zoom-with-python-and-opencv-c279fb6cccbf . Should be a quick fix. But not sure when I can try

2. https://arcoresearchgroup.wordpress.com/2020/06/02/virtual-camera-for-opencv-using-v4l2loopback/ This is the same approach i use. There is a command to test if llopback device works at all:

gst-launch-1.0 videotestsrc ! v4l2sink device=/dev/video5

Can you test it on your side?
