commit 999b753ff0f4dc872077f4fa90d465e948cbe656 r2200
Author: Jason Garrett-Glaser <jason@x264.com>
Date:   Tue May 8 15:42:56 2012 -0700

    Threaded lookahead
   
    Split each lookahead frame analysis call into multiple threads.  Has a small
    impact on quality, but does not seem to be consistently any worse.
   
    This helps alleviate bottlenecks with many cores and frame threads. In many
    case, this massively increases performance on many-core systems.  For example,
    over 100% faster 1080p encoding with --preset veryfast on a 12-core i7 system.
    Realtime 1080p30 at --preset slow should now be feasible on real systems.
   
    For sliced-threads, this patch should be faster regardless of settings (~10%).
   
    By default, lookahead threads are 1/6 of regular threads.  This isn't exacting,
    but it seems to work well for all presets on real systems.  With sliced-threads,
    it's the same as the number of encoding threads.

    Fix some bugs in mb_info code

commit 69a0443e7d8ab032a7f3c3468a42177d5e64daa2 r2197
Author: Jason Garrett-Glaser <jason@x264.com>
Date:   Thu Mar 29 14:14:07 2012 -0700

    Add mb_info API for signalling constant macroblocks
    Some use-cases of x264 involve encoding video with large constant areas of the frame.
    Sometimes, the caller knows which areas these are, and can tell x264.
    This API lets the caller do this and adds internal tracking of modifications to macroblocks to avoid problems.
    This is really only suitable without B-frames.
    An example use-case would be using x264 for VNC.

    ICL/MSVS: Fix shared library generation and usage
    MSVS requires exported variables to be declared with the DATA keyword, and requires that imported variables be declared with dllimport.
    This does not fix x264 cli being unable to use a shared library built by ICL however.

    Fix sliced-threads ratecontrol bug
    Was using qp instead of qscale; could cause NANs (not to mention less accurate results).

commit 5c85e0a2b7992fcaab09418e3fcefc613cffc743 r2184
Author: Anton Mitrofanov <Bugmaster@narod.ru>
Date:   Sun Mar 11 23:08:18 2012 -0700

    Fix clobbering of mutex/cvs
    Regression in r2183.
    Bizarrely seemed to work on many platforms, but crashed on win64 and may have been slower.
    Only affected sliced threads during encoding, but could cause crashes on x264 encoder close even without sliced threads.

commit c522ad1fed167d0e985e4f9dcdee042473cf74db r2183
Author: Jason Garrett-Glaser <jason@x264.com>
Date:   Fri Feb 24 13:34:39 2012 -0800

    Sliced-threads: do hpel and deblock after returning
    Lowers encoding latency around 14% in sliced threads mode with preset superfast.
    Additionally, even if there is no waiting time between frames, this improves parallelism, because hpel+deblock are done during
    the (singlethreaded) lookahead.
    For ease of debugging, dump-yuv forces all of the threads to wait and finish instead of setting b_full_recon.

    x86inc: switch to amdnops
    Recent AMD CPUs' instruction decoders choke horribly on extremely long nops (i.e. with 4 prefixes).
    Won't affect much, since we don't use ALIGN much.

    BMI1 decimate functions
    Intel was nice enough to make tzcnt equal to "rep bsf", which is backwards-compatible.
    This means we don't actually have to add new functions to make it work.

    Add row-reencoding support to VBV for improved accuracy
    Extremely accurate, possibly 100% so (I can't get it to fail even with difficult VBVs).
    Does not yet support rows split on slice boundaries (occurs often with slice-max-size/mbs).
    Still inaccurate with sliced threads, but better than before.

    Add an small per-MB cost penalty for lowres
    Helps avoid VBV predictors going nuts with very low-cost MBs.
    One particular case this fixes is zero-cost MBs: adaptive quantization decreases the QP a lot, but (before this patch),
    no cost penalty gets factored in for this, because anything times zero is zero.

    x86inc: support yasm -f win64
    Not necessary for x264, as -m amd64 already does the right thing, but used by external users of x86inc.

commit 02c3d5ec58d6bcbc5e22715ae80d53d8556f3c8f r2172
Author: Henrik Gramner <hengar-6@student.ltu.se>
Date:   Wed Feb 1 23:52:48 2012 +0100

    Fix incorrect zero-extension assumptions in x86_64 asm
    Some x264 asm assumed that the high 32 bits of registers containing "int" values would be zero.
    This is almost always the case, and it seems to work with gcc, but it is *not* guaranteed by the ABI.
    As a result, it breaks with some other compilers, like Clang, that take advantage of this in optimizations.
    Accordingly, fix all x86 code by using intptr_t instead of int or using movsxd where neccessary.
    Also add checkasm hack to detect when assembly functions incorrectly assumes that 32-bit integers are
    zero-extended to 64-bit.
