Preventing the Error in the Future
Once you have recovered your video, adopt these best practices to avoid seeing the "empty segment" error again:
- Download immediately after the page loads. Do not open the page, walk away for an hour, and then hit download. Tokens expire.
- Keep the source video playing. Many sites keep tokens alive only while the video is actively streaming. Mute the tab and let it run in the background as you download.
- Do not pause downloads for long periods. If you pause a download for more than 30 minutes, the remaining segments will almost certainly have expired tokens.
- Update weekly. Streaming platforms change code weekly. Update Ant and your browsers every Friday.
- Use a download manager as a backup. Configure Ant to fall back to an external manager like IDM or Xtreme Download Manager for problematic streams.
Fix 3: Reset the Extension
Sometimes the extension cache gets corrupted.
- Click on the Ant Video Downloader icon in your browser toolbar.
- Go to Settings or Options.
- Look for a "Clear History" or "Reset" button.
- Refresh the video page and try downloading again.
