This is a throwaway test deployment, separate from the live
surfersofindia.com/surfstats-app/ — nothing here has been pushed
to the real site.
It reuses the real trim.html flow against a real clip from the
Mahabs event, with two changes:
ffmpeg-core.wasm now serves as application/wasm with a week-long
Cache-Control, instead of uncached text/plain.-c copy (remux) instead of a full
libx264/aac re-encode.Click through and press Download trimmed clip — the status line
shows a running total, and the browser console ([trim-preview]
lines) logs a stage-by-stage breakdown: engine load / clip fetch / trim.
Compare that against the same clip on the live
production trim.html.
Real clip: 720p, 90s, ~30MB — one of the longer ones on the live event, so it's a good stress test.
