From: Online architecture for predicting live video transcoding resources
Parameter | Description |
|---|---|
Resolution | 256 × 144 (197 kbps), 640 × 360 (829 kbps), 854 × 480 (1380 kbps) |
Video files | 50 popular video files (length > 4 min) |
Test length | 10 h (a new transcoding task every 15 s) |
