FFmpeg Achieves 100x Speedup with Handwritten Assembly
2025-07-21
The FFmpeg developers have announced a significant performance boost thanks to a new patch utilizing handwritten assembly code. While the 100x speedup applies specifically to the 'rangedetect8_avx512' function, not the entire FFmpeg application, it's still a remarkable achievement. Users with AVX512 support will see the dramatic improvement, while those without will still experience a 64% speedup via the 'rangedetect8_avx2' code path. This highlights the continued relevance of hand-optimized assembly in specific performance-critical scenarios, showcasing FFmpeg's dedication to optimization.
