- 1Upload + transcode: Accept uploads and transcode to multiple bitrates/resolutions as HLS segments with FFmpeg.
- 2Delivery: Store segments in object storage and serve through a CDN for low-latency adaptive playback.
- 3App features: Add search, channels, comments, and likes with a relational backend.
- 4Analytics: Track views, watch-time, and drop-off; show creators a basic analytics page.
Key features to implement
- ✓Adaptive-bitrate HLS playback
- ✓Background transcoding pipeline
- ✓CDN delivery
- ✓Search and engagement
- ✓View/watch-time analytics
💡 Unique twist to stand out
Add a queue-based, autoscaling transcoder fleet so a burst of uploads processes in parallel without blocking playback.
