# The multimedia/x264 port

## x264-20120520 – free H264/AVC encoder

## Description

    x264 is a free library for encoding H264/AVC video streams.

    This program requires a processor with recent instructions (MMX/SSE for
    i386, AltiVec for powerpc).

    Encoder 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: constant quantizer, single or multipass ABR, optional VBV
     * 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
     * Interlacing
