Decoder Complexity Aware AV1 Encoding Optimization
summary
AV1 encoder work shows concrete wins not promises: libaom 10x speedup with >10% BD‑rate improvement and wide encoder families SVT‑AV1, rav1e and libaom. dav1d proves software decoding viability on phones but low‑end Snapdragon 801 struggles at high bitrates. Turning off tiny or huge partitions cuts decoder work while costing ~1% coding efficiency and boosting encoder speed ~9% for some settings. A case study pushes dav1d from 78 to 134 fps (2.24×) with ~5% BD‑rate loss dav1d decoding 78→134 fps (2.24×).
