External Libraries

---

• imageio
• pygame for python3
• tkinter
• PIL
• numpy
• pickle

Setup and Install Libraries

---

• sudo -H pip3 install imageio
• sudo pip3 install setuptools

Objective

---

Utilize RTSP protocol to send requests from client to server. Utilize RTP to transfer data for live-stream from server to client. Create a videoplayer-esque GUI for user to send requests and display live-stream video.

Methods

---

1. Server and client establish TCP connection for RTSP protocol.
2. Client sends RTSP requests:
   • Setup: Required before any other actions.
   • Play: Begin streaming session using RTP protocol.
   • Pause: Halt server-side data transfer.
   • Teardown: Terminate client-side application and close connection gracefully.
3. After setup request is sent to the server, the client may begin the live-stream, pause the live-stream, teardown the connection.
