Currently profile 5, profile 8.1 and profile 8.2 enabled, Default 0 (disabled) * option:: '--dolby-vision-rpu' File containing Dolby Vision RPU metadata. If given, x265's Dolby Vision metadata parser will fill the RPU field of input pictures with the metadata read from the file. The library will interleave access units with RPUs in the bitstream. Default NULL (disabled). * option:: '--zonefile <filename>' specifies a text file which contains the boundaries of the zones where each of zones are configurable. * option:: '--qp-adaptation-range' Delta-QP range by QP adaptation based on a psycho-visual model. Default 1.0. * option:: '--refine-ctu-distortion <0/1>' store/normalize ctu distortion in analysis-save/load. Default 0. * Experimental feature option:: '--hevc-aq' enables adaptive quantization. It scales the quantization step size according to the spatial activity of one coding unit relative to frame average spatial activity. This AQ method utilizes the minimum variance of sub-unit in each coding unit to represent the coding unit's spatial complexity.

The previous encode’s information can be packaged using the x265_analysis_data_t data field available in the x265_picture object. * Basic support for segmented (or chunked) encoding added with --vbv-end that can specify the status of CPB at the end of a segment. String this together with --vbv-init to encode a title as chunks while maintaining VBV compliance! * --force-flush can be used to trigger a premature flush of the encoder. This option is beneficial when input is known to be bursty, and may be at a rate slower than the encoder. * Experimental feature --lowpass-dct that uses truncated DCT for transformation. Encoder enhancements * Slice-parallel mode gets a significant boost in performance, particularly in low-latency mode. * x265 now officially supported on VS2017. * x265 now supports all depths from mono0 to mono16 for Y4M format. API changes * Options that modified PPS dynamically (--opt-qp-pps and --opt-ref-list-length-pps) are now disabled by default to enable users to save bits by not sending headers. If these options are enabled, headers have to be repeated for every GOP. * Rate-control and analysis parameters can dynamically be reconfigured simultaneously via the x265_encoder_reconfig API. * New API functions to extract intermediate information such as slice-type, scenecut information, reference frames, etc. are now available. This information may be beneficial to integrating applications that are attempting to perform content-adaptive encoding. Refer to documentation on x265_get_slicetype_poc_and_scenecut, and x265_get_ref_frame_list for more details and suggested usage. * A new API to pass supplemental CTU information to x265 to influence analysis decisions has been added. Refer to documentation on x265_encoder_ctu_info for more details.

The mapping was also adjusted to improve quality of the encodes with minimal impact to performance. * CSV logging feature (enabled by --csv) is now part of the library; it was previously part of the x265 application. Applications that integrate libx265 can now extract frame level statistics for their encodes by exercising this option in the library. * Globals that track min and max CU sizes, number of slices, and other parameters have now been moved into instance-specific variables. Consequently, applications that invoke multiple instances of x265 library are no longer restricted to use the same settings for these parameter options across the multiple instances. * x265 can now generate a seprate library that exports the HDR10+ parsing API. Other libraries that wish to use this API may do so by linking against this library. Enable ENABLE_HDR10_PLUS in CMake options and build to generate this library. * SEA motion search receives a 10% performance boost from AVX2 optimization of its kernels. * The CSV log is now more elaborate with additional fields such as PU statistics, average-min-max luma and chroma values, etc. Refer to documentation of --csv for details of all fields. * x86inc.asm cleaned-up for improved instruction handling. API changes * New API x265_encoder_ctu_info() introduced to specify suggested partition sizes for various CTUs in a frame. To be used in conjunction with --ctu-info to react to the specified partitions appropriately. * Rate-control statistics passed through the x265_picture object for an incoming frame are now used by the encoder. * Options to scale, reuse, and refine analysis for incoming analysis shared through the x265_analysis_data field in x265_picture for runs that use --analysis-reuse-mode load; use options --scale, --refine-mv, --refine-inter, and --refine-intra to explore. * VBV now has a deterministic mode. Use --const-vbv to exercise. Bug fixes * Several fixes for HDR10+ parsing code including incompatibility with user-specific SEI, removal of warnings, linking issues in linux, etc. * SEI messages for HDR10 repeated every keyint when HDR options (--hdr-opt, --master-display) specified. - soname bump to 130. ------------------------------------------------------------------- Thu Apr 27 14:15:13 UTC 2017 - joerg.lorenzen@ki.tng.de - Update to version 2.4 Encoder enhancements * HDR10+ supported. Dynamic metadata may be either supplied as a bitstream via the userSEI field of x265_picture, or as a json jile that can be parsed by x265 and inserted into the bitstream; use --dhdr10-info to specify json file name, and --dhdr10-opt to enable optimization of inserting tone-map information only at IDR frames, or when the tone map information changes. * Lambda tables for 8, 10, and 12-bit encoding revised, resulting in significant enhancement to subjective visual quality. * Enhanced HDR10 encoding with HDR-specific QP optimzations for chroma, and luma planes of WCG content enabled; use --hdr-opt to activate. * Ability to accept analysis information from other previous encodes (that may or may not be x265), and selectively reuse and refine analysis for encoding subsequent passes enabled with the --refine-level option. * Slow and veryslow presets receive a 20% speed boost at iso-quality by enabling the --limit-tu option. * The bitrate target for x265 can now be dynamically reconfigured via the reconfigure API. * Performance optimized SAO algorithm introduced via the --limit-sao option; seeing 10% speed benefits at faster presets. API changes * x265_reconfigure API now also accepts rate-control parameters for dynamic reconfiguration. * Several additions to data fields in x265_analysis to support --refine-level: see x265.h for more details.

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 09:11:02 UTC 2015 - aloisio@gmx.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 20:08:06 UTC 2015 - aloisio@gmx.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 09:07:11 UTC 2015 - aloisio@gmx.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 8 04:53:31 UTC 2014 - crrodriguez@opensuse.org - Ensure we use the proper CXXFLAGS, CFLAGS and therefore debuginfo packages are generated correctly. ------------------------------------------------------------------- Sat Oct 4 15:24:23 UTC 2014 - aloisio@gmx.com - Bumped to version hg20140928 ------------------------------------------------------------------- Thu Jun 5 14:55:45 UTC 2014 - guillaume@opensuse.org - Fix ARM build with arm.patch from Arch Linux: https://github.com/archlinuxarm/PKGBUILDs/blob/master/extra/x265/arm.patch ------------------------------------------------------------------- Thu May 08 00:00:00 UTC 2014 - Manfred.Tremmel@iiv.de - added baselibs.conf ------------------------------------------------------------------- Mon Mar 24 00:00:00 UTC 2014 - Manfred.Tremmel@iiv.de - initial build of todays mercurial checkout
