Why a video URL might not work
- The link expired (many CDNs sign URLs with a short TTL).
- CORS headers are missing, so browsers refuse to load it.
- It's geo-restricted or behind auth.
- The file/manifest was moved or deleted.
Frequently Asked Questions
- Does this download the video?
- No — it only attempts playback in your browser to confirm the link is live.
- What does a CORS error mean?
- The video server didn't allow cross-origin access. The owner must add Access-Control-Allow-Origin headers.
