发生了什么: NVIDIA Video Codec SDK 13.1 adds AV1 B-frames up to 31, frame-accurate seeking, per-macroblock decode statistics, and zero-copy transcode with redesigned modular architecture.
为何重要: Video engineers building transcoding pipelines, AI inference workflows needing specific frames, and real-time video analytics applications benefit from these performance and efficiency gains.
注意: Hierarchical Reference Mode increases video memory consumption. Frame-accurate seek requires GOP-aware handling and may reset decoders for backward seeks on non-seekable streams.
