x264 is a free library for encoding H264/AVC video streams. The code is written from scratch by Laurent Aimar, Loren Merritt, Eric Petit(OS X), Min Chen (vfw/asm), Justin Clay(vfw), MРµns RullgРµrd, Christian Heine (asm), and Alex Izvorski (asm).Features: • CAVLC/CABAC • Multi-references • Intra: all macroblock types (16x16, 8x8, and 4x4 with all predictions) • Inter P: all partitions (from 16x16 down to 4x4) • Inter B: partitions from 16x16 down to 8x8 (including skip/direct) • Ratecontrol: optional VBV, single or multipass ABR, constant quantizer • Scene cut detection • Adaptive B-frame placement • B-frames as references / arbitrary frame order • 8x8 and 4x4 adaptive spatial transform • Lossless mode • Custom quantization matrices • Parallel encoding of multiple slices Note: x264 is still in early development stage.
