* Chroma subsampling format YUV 4:0:0 is now fully supported and tested New Features:
* Quant offsets: This feature allows block level quantization offsets to be specified for every frame. An API-only feature.
* --intra-refresh: Keyframes can be replaced by a moving column of intra blocks in non-keyframes.

* A new aq-mode that provides additional biasing for low-light conditions.
* An improved scene cut detection logic that allows ratecontrol to manage visual quality at fade-ins and fade-outs better. Preset and Tune Options:
* tune grain + Increases psyRdoq strength to 10.0, and rdoq-level to 2. + qg-size
* Default value changed to 32.- soname bump to 68- Reworked arm.patch for 1.8
* Fri May 29 2015 aloisioAATTgmx.com- soname bump to 59- Update to version 1.7
* large amount of assembly code optimizations
* some preliminary support for high dynamic range content
* improvements for multi-library support
* some new quality features (full documentation at: http://x265.readthedocs.org/en/1.7)
* This release simplifies the multi-library support introduced in version 1.6. Any libx265 can now forward API requests to other installed libx265 libraries (by name) so applications like ffmpeg and the x265 CLI can select between 8bit and 10bit encodes at runtime without the need of a shim library or library load path hacks. See --output-depth, and http://x265.readthedocs.org/en/1.7/api.html#multi-library-interface
* For quality, x265 now allows you to configure the quantization group size smaller than the CTU size (for finer grained AQ adjustments). See --qg-size.
* x265 now supports limited mid-encode reconfigure via a new public method: x265_encoder_reconfig()
* For HDR, x265 now supports signaling the SMPTE 2084 color transfer function, the SMPTE 2086 mastering display color primaries, and the content light levels. See --master-display, --max-cll
* x265 will no longer emit any non-conformant bitstreams unless - -allow-non-conformance is specified.
* The x265 CLI now supports a simple encode preview feature. See - -recon-y4m-exec.
* The AnnexB NAL headers can now be configured off, via x265_param.bAnnexB This is not configurable via the CLI because it is a function of the muxer being used, and the CLI only supports raw output files. See - -annexb Misc:
* --lossless encodes are now signaled as level 8.5
* --profile now has a -P short option
* The regression scripts used by x265 are now public, and can be found at: https://bitbucket.org/sborho/test-harness
* x265\'s cmake scripts now support PGO builds, the test-harness can be used to drive the profile-guided build process.
* Tue Apr 28 2015 aloisioAATTgmx.com- soname bumped to 51- Update to stable version 1.6 Perfomance changes:
* heavy improvements for AVX2 capable platforms (Haswell and later Intel CPUs) and work efficiency improvements for multiple-socket machines. API changes:
* --threads N replaced by --pools N,N and --lookahead-slices N
* --[no-]rdoq-level N - finer control over RDOQ effort
* --min-cu-size N - trade-off compression for performance
* --max-tu-size N - trade-off compression for performance
* --[no-]temporal-layers - code unreferenced B frames in temporal layer 1
* --[no-]cip aliases added for --[no-]constrained-intra
* Added support for new color transfer functions \"smpte-st-2084\" and \"smpte-st-428
* --limit-refs N was added, but not yet implemented
* Deprecated x265_setup_primitives() was removed from the public API and is no longer exported DLLs Threading changes:
* The x265 thread pool has been made NUMA aware.
* The --threads parameter, which used to specify a global pool size, has been replaced with a --pools parameter which allows you to specify a pool size per NUMA node (aka CPU socket or package). The default is still to allocate one pool worker thread per logical core on the machine, but with --pools one can isolate those threads to a given socket.
* Other than socket isolation, the biggest visible change in the NUMA aware thread pools is the increase in work efficiency. The total utilization will generally decrease but the performance will increase since worker threads spend less time context switching. Also, the threading of the lookahead was made more work-efficient. Each lookahead job is a much larger piece of work. Before (1.5): disable thread pool: --threads 1 default thread pool: --threads 0 restrict to 4 threads: --threads 4 After (1.6): disable thread pools: --pools 0 default thread pools: --pools
* restrict to 4 threads: --pools 4 restrict to 4 threads on socket 1: --pools -,4 restrict to all threads on socket 0: --pools +,- Multi-lib interface:
* In order to support runtime selection of a libx265 shared library, we have introduced an x265_api structure and an x265_api_get() function. Applications which use this interface to acquire the libx265 functional interface will be able to use shim libraries to bind a particular build of libx265 at run time. See the API documentation for full details.
* Sun Feb 22 2015 aloisioAATTgmx.com- soname bump- Update to stable version 1.5
* improvements in Main10 compression efficiency and performance and psycho-visual optimizations now enabled by default Feature additions:
* analysis re-use features have been completed
* rate control zones have been introduced
* --tune grain introduced
* deblocking tC and Beta offsets are now configurable
* denoise is seperately configurable for inter and intra CUs
* frame based CSV logging has been improved
* New support for VTune task profiles Presets and defaults:
* ultrafast no longer disables the deblocking loop filter
* psy-rd defaults to 0.3 (was 0, disabled)
* psy-rdoq defaults to 1.0 (was 0, disabled)
* aq-mode defaults to 1 (was 2, auto-variance)
* 4:2:2 and 4:4:4 encodes no longer generate compliance warnings API changes:
* param.rc.rateTolerance has been removed and replaced with a simpler param.rc.bStrictCbr flag.
* --log-level debug is now --log-level 4 instead of --log-level 3. A new \'frame\' log level was inserted at level 3 in order to support frame level CSV logging without also enabling frame level console logging. Using the string name \'debug\' is unambiguous as its behavior has not changed.- version 1.4
* large refactoring in the analysis code Feature additions:
* --pmode (parallel mode decision)
* --pme (parallel motion estimation). Presets and defaults:
* --amp is now respected in RD levels 2, 3, and 4 (previously only in 5 and 6).
* --b-intra is now respected in all RD levels.
* --fast-cbf, which has only ever effective at RD levels 5 and 6, is no longer enabled uselessly in the fastest presets.
* --weightb is now enabled by default at presets slower, veryslow, and placebo.
* --cu-lossless was changed to only attempt a lossless encode of the best lossy encode method. This made --cu-lossless a much less expensive encode option to have enabled, and hopefully made the feature more robust and maintainable.
* The upper threshold for --psy-rdoq was raised to 50 (from 10) since the higher values were found to be beneficial for sources with high frequency noise (film grain).
* The default thread pool size logic was updated to account for the addition of --pmode and --pme (if WPP is disabled but --pmode or - -pme are enabled, a thread pool is still allocated).
* Mon Dec 08 2014 crrodriguezAATTopensuse.org- Ensure we use the proper CXXFLAGS, CFLAGS and therefore debuginfo packages are generated correctly.
* Sat Oct 04 2014 aloisioAATTgmx.com- Bumped to version hg20140928
* Thu Jun 05 2014 guillaumeAATTopensuse.org- Fix ARM build with arm.patch from Arch Linux: https://github.com/archlinuxarm/PKGBUILDs/blob/master/extra/x265/arm.patch
* Thu May 08 2014 Manfred.TremmelAATTiiv.de- added baselibs.conf
* Mon Mar 24 2014 Manfred.TremmelAATTiiv.de- initial build of todays mercurial checkout
