Dekho: An on-demand video streaming server

Some Achievements ✨

We launched Dekho on Peerlist in the 3rd Week of January 2025 and we had a pretty good response.

Star History

Overview

Dekho is a research and study project aimed at understanding and learning about audio and video streaming. Our primary focus was on implementing the HLS (HTTP Live Streaming) protocol to build an on-demand video streaming server.

Setup Instructions

Basic Steps

• Clone the repository
• Create an Appwrite storage bucket
• Make sure that you make a note of APPWRITE_KEY, APPWRITE_PROJECT_ID and the BUCKET_ID.

With Docker

• Install docker-compose on your machine.
• cd into the root of the repository.
• Create a .env file using .env.docker as a reference.
• Just run docker-compose up to start the server.

Without Docker

• Install the make utility because we have created a Makefile to ease the setup
• Now we are moving to the dependency installation steps.
• This project needs go version go1.23, ffmpeg utility and psql (PostgreSQL) 16.3 database.
• To install these, and the Go dependencies, run make install-dev.
• The make install-dev takes care of installing PostgreSQL, Go, FFMpeg, golang-migrate and Go dependencies.
• Run make start-postgres to start the postgres service.
• Create a database user by running this command sudo -u postgres createuser -s username_here -P
• -P will prompt for a password.
• Enter the psql shell by running this command sudo -u postgres psql and create a database by running CREATE DATABASE <database_name>;.
• Create a .env file using .env.local as a reference.
• Once the dependencies are installed successfully, run make cleanstart.
• This command will create all the necessary folders and start the server on http://127.0.0.1:8000
• If you just want to run the server, run: make start
• If you just want to clean up, run: make clean

Technologies Used

• Server: Go
• Database: PostgreSQL
• Storage: Appwrite Storage
• Video Processing: FFMPEG for breaking down videos into .ts chunks
• Video Player: HLS.js
• Frontend: HTML, CSS, JS

Key Resources

Our journey has been greatly enriched by the insights and guidance from various resources. A pivotal article that set us on the right path is "Learning the basics of video streaming with Golang" by Rohit Mundra.
