Summary

Added in-memory caching to the /thumbnail endpoint so repeated requests for the same video URL do not re-run ffmpeg.

What changed

  • Added node-cache with a 1 hour TTL
  • Cached thumbnails by the url query parameter
  • On cache hit, returned the stored JPEG buffer directly
  • On cache miss, generated the thumbnail with ffmpeg and stored it in cache
  • Set the ffmpeg binary path using @ffmpeg-installer/ffmpeg
  • Kept the existing Content-Type and Cache-Control headers
  • Kept proper error handling

Verification

  • Confirmed /health returns 200 OK
  • Confirmed /thumbnail returns a JPEG response
  • Confirmed repeated requests for the same URL are served from cache

Notes

  • Changes are limited to the implementation files only

close #2
