Dotstream Video-Streaming System (DSVS)

High-Quality, Low-Latency Video Streaming Solution

This project was developed for Mindhop Inc. While I'm excited to discuss the technical skills and architecture patterns employed, specific implementation details are covered under NDA. I'm happy to demonstrate these skills through other means during technical discussions.

Project Overview

DSVS is a high-performance video-streaming system designed for low-latency, high-quality delivery. The system leverages advanced video encoding, multi-bitrate streaming, and adaptive bitrate adjustment to provide seamless streaming experiences. It integrates with a robust cloud infrastructure for real-time content distribution.

Core Technologies

Backend Development
  • Python/Flask
  • FFmpeg for video processing
  • WebSocket for real-time communication
  • PostgreSQL for metadata storage
Infrastructure & DevOps
  • AWS S3 for content storage
  • AWS CloudFront for content delivery
  • Docker for deployment
  • Linux for server management
Video & Streaming Technologies
  • HLS (HTTP Live Streaming)
  • MPEG-DASH
  • Adaptive Bitrate Streaming
  • Multi-bitrate Encoding

Frontend Implementations

We developed two frontends for testing and production:

Flask-based Frontend (Testing)

This frontend was developed to test and debug the video streaming functionality in isolation. Built with Flask, it allowed us to rapidly iterate through different video processing configurations and validate the results before full-scale deployment.

  • Stream testing with FFmpeg integration
  • Rapid configuration for video transcoding
  • WebSocket integration for real-time video monitoring
React Next.js Frontend (Production)

The React Next.js frontend was integrated into the broader dotstream™ application, providing users with a high-quality, interactive interface for seamless video streaming. This frontend handles differentiated video streams, allowing users to switch between multiple qualities based on network conditions.

  • Integrated with the broader React Next.js app
  • Support for adaptive bitrate streaming (HLS, MPEG-DASH)
  • Multi-stream management for different video qualities
  • Client-side controls for video playback

Technical Achievements

  • Designed and implemented multi-bitrate adaptive streaming for smooth user experiences
  • Optimized FFmpeg workflows for efficient video encoding and transcoding
  • Integrated AWS CloudFront for low-latency content delivery
  • Automated deployment and scaling using Docker and AWS infrastructure
  • Successfully implemented differentiated video streams within the React Next.js app
