libx264 is a free library for encoding H264/AVC video streams. The code
is written from scratch.
Encoder features:
- Multi-references
- Intra: all macroblock types (16x16, 8x8, and 4x4 with all
- Inter P: all partitions (from 16x16 down to 4x4)
- Inter B: partitions from 16x16 down to 8x8 (including skip/direct)
- Ratecontrol: constant quantizer, single or multipass ABR, optional
- 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.
This package includes the shared library needed to run x264-based
