This app leverages Cloudinary’s powerful video optimization features to provide the ultimate viewing experience.
- Definition: Dynamically adjusts video quality based on real-time network conditions.
- Optimization:
- Cloudinary serves HLS streams with multiple quality levels (
360p, 720p, 1080p
). - The app uses AVPlayer with Cloudinary’s adaptive streaming, ensuring lag-free playback.
- Cloudinary serves HLS streams with multiple quality levels (
- Definition: Prefetches upcoming videos without overloading bandwidth.
- Optimization:
- Cloudinary’s CDN caching & preloading minimize network requests.
- Only the next video is prefetched, reducing unnecessary data consumption.
- Definition: Dynamically resizes and compresses videos to match device specs.
- Optimization:
- Uses Cloudinary’s
q_auto
&f_auto
for automatic format & quality selection. - Reduces file size by 40-60% while maintaining high resolution.
- Uses Cloudinary’s
✅ Result: A lightning-fast video feed with minimal buffering and the best possible quality on any network or device.
