AV1 Video Encoding Standard and BILIAV1 Self-Developed Encoder

AV1, an open royalty‑free video codec finalized in 2018, delivers roughly 20 % lower bitrate than H.265 and is supported by major players and hardware, while Bilibili’s self‑developed BILIAV1 encoder, built from scratch, beats SVT‑AV1 by 15‑20 % bitrate at equal speed through advanced TRACE debugging, parallel processing and optimized algorithms, with future work targeting P2P and live‑streaming applications.
