#!/bin/bash

#UDP Multicast
#Script streams Audio to the port 5001 and Video to the port 1234 separately.
#Script uses my USB Sound card named "USB" to capture sound & "/dev/video0" video device to capture live video.
#It streams audio and video to all the computers connected to the local area network.
#Use the command : "cat /proc/asound/cards" to display your available sound cards.
#Use the command : "v4l2-ctl --list-devices" to display available video devices. You may need to install v4l2-ctl package before executing the command by running "sudo apt-get install v4l-utils"
#You can also use : "ls -ltrh /dev/video*" to list video devices.
