x264 Video Codec r1115

x264 Video Codec r1115 is designed as a free and flexible 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), Måns Rullgård, Christian Heine (asm), and Alex Izvorski (asm).
Major Features:

1. CAVLC/CABAC
2.  Multi-references
3.  Intra: all macro-block types (16x16, 8x8, and 4x4 with all predictions)
4.  Inter P: all partitions (from 16x16 down to 4x4)
5.  Inter B: partitions from 16x16 down to 8x8 (including skip/direct)
6.  Rate-control: constant quantiser, single or multi-pass ABR, optional VBV
7.  Scene cut detection
8.  Adaptive B-frame placement
9.  B-frames as references / arbitrary frame order
10.  8x8 and 4x4 adaptive spatial transform
11.  Loss-less mode
12.  Custom quantization matrices
13.  Parallel encoding on multiple CPUs
14.  Interlacing

Enhancements:

1. Fix regression in r1085
2. De-blocking was very slightly incorrect with partitions=all.
3. Bug found by BugMaster.
