Video Streaming Platform with Adaptive Bitrate
Uploads transcoded to HLS with FFmpeg and played at adaptive quality
5-6 weeks build
Overview
Creators upload a video in resumable chunks; a worker queue runs FFmpeg to produce an HLS ladder at several resolutions, segments and a master playlist, plus thumbnails. The player uses hls.js to switch renditions as bandwidth changes, and the backend records watch progress so viewers resume where they left off. Object storage holds the segments and a status page shows each transcoding job.
What makes it stand up
- 01Resumable chunked uploads that survive a dropped connection
- 02FFmpeg worker queue that builds a multi-resolution HLS ladder
- 03Adaptive playback with hls.js and a manual quality selector
- 04Watch history and resume-from-last-position per viewer
- 05Job dashboard showing transcoding progress and failures
