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 features8x8 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
