Multi-lingual Video Streaming POC

The Problem

Serving video in multiple languages — like Netflix does — requires more than just subtitles. Audio tracks, UI language switching, and CDN-efficient delivery all need to work together.

What I Built

A proof of concept streaming platform with multi-language audio track support, language selection UI, adaptive delivery via CloudFront, and FFmpeg-based transcoding pipeline.

Technical Challenges

• Multi-track video packaging with FFmpeg
• Language-aware CDN delivery without re-fetching full video
• Smooth client-side audio track switching
• Cost-efficient storage for multiple language variants

Results & Impact

• Working POC validating multi-lingual streaming architecture
• Foundation for production implementation
