I have the same issue on ubuntu 20.04 LTS and the errror message is the same.

Update 1: webcam works fine on MAC Update 2: Pytorch 1.8.1 + ubuntu = webcam does not work Pytorch 1.9 + ubuntu = webcam does not work Pytorch 1.8.1 + mac = webcam works Pytorch 1.9 + mac = webcam works

It seems to be a ubuntu issue
