软件介绍

x264是一个基于h.264/AVC的免费开源的视频解码器，该版本为win32平台下的VFW codec版。

Encoder features

• 8x8 and 4x4 adaptive spatial transform

• Adaptive B-frame placement

• B-frames as references / arbitrary frame order

• CAVLC/CABAC entropy coding

• Custom quantization matrices

• Intra: all macroblock types (16x16, 8x8, 4x4, and PCM with all  predictions)

• Inter P: all partitions (from 16x16 down to 4x4)

• Inter B: partitions from 16x16 down to 8x8 (including  skip/direct)

• Interlacing (MBAFF)

• Multiple reference frames

• Ratecontrol: constant quantizer, constant quality, single or  multipass ABR, optional VBV

• Scenecut detection

• Spatial and temporal direct mode in B-frames, adaptive mode  selection

• Parallel encoding on multiple CPUs

• Predictive lossless mode

• Psy optimizations for detail retention (adaptive quantization,  psy-RD, psy-trellis)

• Zones for arbitrarily adjusting bitrate distribution
