Gstreamer-UDP

Streaming LIVE webcam feed using GStreamer . A Python-based GStreamer application for streaming video between a sender and receiver using UDP transmission over same network.

Required:

• Linux System

• Ensure both sender and receiver are on the same network.

• Adjust firewall settings if necessary to allow UDP communication.

Files

• sender.py: Python script for streaming video from a device to a specified IP address and port.

• receiver.py: Python script for receiving and displaying video streams on a specified port.

Check Network connection of both Receiver and Sender

• In terminal type ip addr or ipconfig find your ipv4 address from there.
• Now in Receiver's terminal type ping sender_IP and in Sender's terminal type ping receiver_IP.
• If both are able to communicate with each other then Proceed.

Installation:

Install dependencies:

sudo apt-get install python3 sudo apt install python3-pip pip install -r requirements.txt (On Both Sender and Receiver Side)

Usage:

Sender Side (sender.py)

To run the sender script, execute the following command:

python3 sender.py -ip <destination_ip> -port <port_number> -device <device_index>

e.g python3 sender.py -ip 192.168.1.1 -port 8081 -device 2 You can resize the stream size also by changing width=640,height=480

Replace <destination_ip> with Receiver IP Address, <port_number> with any Open or Free Port. Replace <device_index> with (0,1,2...) (default is 0) , check using /dev/device* in terminal for the device index.

Receiver Side (receiver.py)

To run the receiver script, execute the following command:

python3 receiver.py -port <port_number> e.g python3 receiver.py -port 8081 Replace <port_number> with the same port used by the sender.

Streamimng Multiple Webcams:

• Use New Terminal Window everytime for another webcam streaming while Transferring other webcam Stream or Viewing stream.

• Use different ports while executing the sender side command, if the receiver end is not same use IP Address of the other receive and another Unused/Open Port.
• Execute the Receiver Side command by Specifying the used port for particular required stream into the new terminal window.
• New Window will Pop-Up use that to view streams
• You can resize the stream size also by changing width=640,height=480

ALTERNATE METHOD TO RUN THE SAME-Streaming SETUP

On Sender Side-

In Terminal

sudo apt-get update
sudo apt-get install python3
sudo apt-get install gstreamer1.0-tools

gst-launch-1.0 v4l2src device=/dev/video0 ! videoconvert ! videoscale ! video/x-raw,width=640,height=480 ! jpegenc ! rtpjpegpay ! udpsink host=RECIEVER_IP_ADDR port=ANY_OPEN_PORT

Here /dev/video0 — gives the stream of default webcam. For using Multiple Cameres change the device ( /dev/video[otherNumber] ) for other connected webcam. By checking using (/dev/video*)

On Receiver's Side -

gst-launch-1.0 -e -v udpsrc port=PREVIOUS_USED_PORT ! application/x-rtp,encoding-name=JPEG,payload=26 ! rtpjpegdepay ! jpegdec ! autovideosink
