❌ Common Problems

Users may experience:

  • Video not loading
  • Infinite buffering
  • Black screen

✅ Basic Checks (First Step)

Before anything else, verify:

  • Video URL is correct and accessible

  • Server is online and not blocked
  • No typo in video URL

🎥 Video Not Playing

Possible Causes:

  • Invalid or broken video URL
  • Unsupported format
  • Server blocking requests

Solution:

  • Test video URL directly in the browser
  • Use HLS (.m3u8) for better compatibility
  • Check server permissions (CORS)

⏳ Buffering Issues

Possible Causes:

  • Slow hosting/server
  • Large video files
  • No adaptive streaming

Solution:

  • Use HLS streaming instead of MP4
  • Enable multiple sources (fallback)
  • Use CDN for video delivery

🔇 Audio Not Working

Possible Causes:

Solution:

  • Check the audio track in the video file

Solution:

⚠️ Format Not Supported

Solution:

  • Convert video to MP4 (H.264)

🔒 Video Not Loading Due to Security

Possible Causes:

  • Verify signed URL validity

MovieEngine playback troubleshooting player not working explained

Start with the basic checks in this guide: confirm the video URL is correct and accessible, the file format is supported (MP4, HLS, DASH), the server is online and not blocked, and there is no typo in the video URL. Most playback problems trace back to one of these points, so verifying them first saves time before working through the individual issues below.

For each issue, match the cause to the solution: a video that does not play may have an invalid or broken URL, an unsupported format, or a server blocking requests — test the URL directly, use HLS (.m3u8) for better compatibility, and check server permissions (CORS). Buffering usually comes from slow hosting, large files, or no adaptive streaming, so use HLS instead of MP4, enable multiple sources for fallback, and use a CDN. Audio problems may mean a missing audio track, browser restrictions, or mute enabled; subtitle problems may mean the wrong format, an invalid URL, or a language not set — use .vtt only, verify the URL is accessible, and set the correct language code. Format errors call for converting to MP4 (H.264) or using HLS or DASH, security blocks call for proper CORS headers, a firewall check, and a signed URL check, and mobile issues call for mute autoplay, HLS streaming, and testing on a real device. As a rule, use HLS for production sites, add multiple sources for fallback, use a CDN for faster delivery, and test videos before publishing.
