x264 is a free software library and application for encoding video
|
|
streams into the H.264/MPEG-4 AVC format.
|
|
|
|
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
