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.

Six Degrees of Freedom (6DoF) Video: Standards, Challenges, and Practical Implementation

Youku’s new 6DoF video approach replaces low‑resolution, bandwidth‑heavy VR by capturing multi‑camera footage, reconstructing full‑depth scenes in the cloud, and streaming standard‑compliant streams that let viewers freely translate and rotate within the content, delivering higher visual quality, AR integration, and new business opportunities.
