x264 Video Codec rev. 2119 x86/x64

Code: 
Changes (2107-2119):

    * Improve yasm version check. Previous check allowed certain earlier versions that weren't fully compatible.;
    * Configure: force PIC for shared build on PARISC and MIPS.;
    * Fix crash if timecode file opening fails.;
    * Mark some local functions as static, cosmetics.;
    * Improve makefile rules. Remove the need for "make clean" after most reconfigures.;
    * checkasm: fix build on ARM. Because of how ALIGNED_ARRAY_16 is defined on ARM, array initialisers cannot be used here.  Use memset() instead.;
    * checkasm: shut up gcc warnings, fix some naming of functions in results.;
    * x86inc: AVX symmetry optimization. 3-arg AVX ops with a memory arg can only have it in src2, whereas SSE emulation of 3-arg prefers to have it in src1 (i.e. the move). So, if the op is symmetric and the wrong one is memory, swap them. Eliminates redundant moves in some cases when using 3-operand without AVX with memory arguments. Also fix movss and movsd in some cases, and flag shufps correctly as float.;
    * Remove unpredictable branch in CABAC dqp.;
    * Pass through user data.;
    * YUV range detection and support for x264CLI. Two new options: --input-range and --range. --input-range forces the range of the input in case of misdetection; auto by default. -- range sets the range of the output; x264cli will convert if  necessary, TV by default. --fullrange is now removed as a CLI option (but the libx264 API is unchanged).;
    * CABAC trellis optimizations: use SIMD quant. Significant speed increase, minor change in output due to rounding.;
    * Modify MBAFF chroma deblock functions to handle U/V at the same time. Allows for more convenient asm implementations.

x264 Video Encoder rev. 2184 x86/x64
14.03.2012

Code: 
[COLOR="DarkOrchid"]Fix clobbering of mutex/cvs. Regression in r2183.[/COLOR] 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.

x264 Encoder


New version r2197, Apr 25

Code: 
r2197
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.

r2196
Faster chroma weight cost calculation

New assembly function with SSE2, SSSE3 and XOP implementations for calculating absolute sum of differences.

r2195
Add Level 5.2 support

r2194
Eradicate all mention of Extended Profile
x264 never supported it and never will because nobody uses it.

r2193
Fix disabling of mbtree when using 2pass encoding and zones

r2192
configure: force select -mXX gcc option for i386/x86-64
Makes multilib compilation more convenient.

r2191
Update config.guess and config.sub
Adds support for a bunch of targets, including:
aarch64 (armv8)
arm-linux-androideabi

r2190
configure: correct use of RC variable and add --extra-rcflags

r2189
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.

r2188
Fix intra-refresh + hrd

r2187
Fix frame input colorspace check

r2186
Fix comment in deblock.c
The code does, in fact, handle CAVLC+8x8dct correctly already.

r2185
Fix sliced-threads ratecontrol bug
Was using qp instead of qscale; could cause NANs (not to mention less accurate results).

r2200
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.

r2199
Add support for RGB formats in bit-depth conversion filter

r2198
Fix some bugs in mb_info code

x264 Video Codec rev. 2245

What's New:

  • Prevent VBV from lowering quantizer too much
  • This code seemed to act up unexpectedly sometimes, creating a situation where in 1-pass VBV mode, a frame's quantizer would drop all the way to qpmin and then shoot back upwards to qpmax, causing serious visual issues.
  • This change may decrease bitrate in VBV mode, but that is preferable to the artifacting produced by this code.
  • Improve subme7 at low QPs and add subme7 support in lossless mode.
