resilient video fetcher: micro-segment downloader for streamed videos on unstable networks

the problem

Trying to watch video streams on low-bandwidth and highly unstable connections frequently results in a nightmare when really in need.

the architecture

A lightweight CLI pipeline designed around taking advantage of the native streaming architecture of small 3-5s video files to ensure 100% data recovery across network drops:

• Micro-Chunking: download each of the 3-5 second segments. A network drop loses kilobytes, not gigabytes.

• Smart State Check: Scans local disk memory on boot to instantly skip existing chunks and resume execution seamlessly.

• Automated Assembly: Executes lossless binary stitching and FFmpeg stream-muxing into a single, perfectly synced .mp4.

core takeaway

Solving infrastructure constraints is about system design and building systems that expect to fail and recover instantly.
