Gstreamer two MJPG Webcams

sideBySide.sh

#!/bin/sh
# Run two video webcam feeds in two different windows
# Script assumes that:
# Microsoft LifeCam Studio is video0
# Logitech c920 is video1
# Both cameras run max 1920x1080 MJPG, but two have both on a USB bus they can run @ 1280x720 max
# MS is made a little smaller
# text overlay and clockoverlay may be added to the pipeline, but render poorly
