| Issue in vanilla libvpx | Eternity Libvpx solution | |------------------------|--------------------------| | Reference frame list grows unbounded over time | Fixed-size, time-decayed reference pool | | Bitrate drift after > 2^31 frames | 64-bit frame counters and periodic rate recalibration | | Memory leaks in long-running encoder sessions | Wrapped encoder context with automatic reset hooks | | Scene cut detection fails after hours due to stale statistics | Adaptive scene sensitivity that resets every 1M frames |
