💡 Pro Tip
Create a playlist of these URLs for automated testing. You can cycle through different streams to test various scenarios and edge cases.
Troubleshooting Test Streams
🚫 Stream Not Loading
- Check if the URL is still active (test streams may be temporary)
- Verify your internet connection
- Try a different browser or clear cache
- Check if CORS is blocking the request
⏳ Slow Performance
- Test servers may have rate limiting
- Your connection might not support 4K streaming
- Try lower quality streams first
- Close other bandwidth-intensive applications
