------------------------------------------------------------------- Thu Jul 27 08:33:52 UTC 2017 - joerg.lorenzen@ki.tng.de - Update to version 2.5 Encoder enhancements * Improved grain handling with --tune grain option by throttling VBV operations to limit QP jumps. * Frame threads are now decided based on number of threads specified in the --pools, as opposed to the number of hardware threads available. 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. Bug fixes * Avoid negative offsets in x265 lambda2 table with SAO enabled. * Fix mingw32 build error. * Seek now enabled for pipe input, in addition to file-based input. * Fix issue of statically linking core-utils not working in linux. * Fix visual artifacts with --multi-pass-opt-distortion with VBV. * Fix bufferFill stats reported in csv. - soname bump to 116. ------------------------------------------------------------------- Fri Feb 24 14:03:24 UTC 2017 - ismail@i10z.com - Update to version 2.3 Encoder enhancements * New SSIM-based RD-cost computation for improved visual quality, and efficiency; use --ssim-rd to exercise. * Multi-pass encoding can now share analysis information from prior passes. * A dedicated thread pool for lookahead can now be specified with --lookahead-threads. * option:–dynamic-rd dynamically increase analysis in areas where the bitrate is being capped by VBV; works for both CRF and ABR encodes with VBV settings. * The number of bits used to signal the delta-QP can be optimized with the --opt-cu-delta-qp option. * Experimental feature option:–aq-motion adds new QP offsets based on relative motion of a block with respect to the movement of the frame. API changes * Reconfigure API now supports signalling new scaling lists. * x265 application’s csv functionality now reports time (in milliseconds) taken to encode each frame. * --strict-cbr enables stricter bitrate adherence by adding filler bits when achieved bitrate is lower than the target. * --hdr can be used to ensure that max-cll and max-fall values are always signaled (even if 0,0). Bug fixes * Fixed scaling lists support for 4:4:4 videos. * Inconsistent output fix for --opt-qp-pss by removing last slice’s QP from cost calculation. ------------------------------------------------------------------- Sun Jan 1 20:32:07 UTC 2017 - ismail@i10z.com - Update to version 2.2 Encoder enhancements * Enhancements to TU selection algorithm with early-outs for improved speed; use --limit-tu to exercise. * New motion search method SEA (Successive Elimination Algorithm) supported now as :option: –me 4 * Bit-stream optimizations to improve fields in PPS and SPS for bit-rate savings through --[no-]opt-qp-pps, --[no-]opt-ref-list-length-pps, and --[no-]multi-pass-opt-rps. * Enabled using VBV constraints when encoding without WPP. * All param options dumped in SEI packet in bitstream when info selected. API changes * Options to disable SEI and optional-VUI messages from bitstream made more descriptive. * New option --scenecut-bias to enable controlling bias to mark scene-cuts via cli. * Support mono and mono16 color spaces for y4m input. * --min-cu-size of 64 no-longer supported for reasons of visual quality. * API for CSV now expects version string for better integration of x265 into other applications. Bug fixes * Several fixes to slice-based encoding. * --log2-max-poc-lsb‘s range limited according to HEVC spec. * Restrict MVs to within legal boundaries when encoding. ------------------------------------------------------------------- Thu Dec 22 12:59:47 UTC 2016 - scarabeus@opensuse.org - Add conditional for the numa-devel again it was not ment to be dropped - Add patch x265.pkgconfig.patch to fix pkgconfig ------------------------------------------------------------------- Tue Dec 20 12:02:33 UTC 2016 - scarabeus@opensuse.org - Switch to use cmake macros ------------------------------------------------------------------- Thu Sep 29 12:26:59 UTC 2016 - ismail@i10z.com - Update to version 2.1 Encoder enhancements * Support for qg-size of 8 * Support for inserting non-IDR I-frames at scenecuts and when running with settings for fixed-GOP (min-keyint = max-keyint) * Experimental support for slice-parallelism. API changes * Encode user-define SEI messages passed in through x265_picture object. * Disable SEI and VUI messages from the bitstream * Specify qpmin and qpmax * Control number of bits to encode POC. Bug fixes * QP fluctuation fix for first B-frame in mini-GOP for 2-pass encoding with tune-grain. * Assembly fix for crashes in 32-bit from dct_sse4. * Threadpool creation fix in windows platform. ------------------------------------------------------------------- Sun Aug 28 11:51:23 UTC 2016 - joerg.lorenzen@ki.tng.de - Update to version 2.0 API and Key Behavior Changes * x265_rc_stats added to x265_picture, containing all RC decision points for that frame. * PTL: high tier is now allowed by default, chosen only if necessary. * multi-pass: First pass now uses slow-firstpass by default, enabling better RC decisions in future passes. * pools: fix behaviour on multi-socketed Windows systems, provide more flexibility in determining thread and pool counts. * ABR: improve bits allocation in the first few frames, abr reset, vbv and cutree improved. New Features * uhd-bd: Enforce Ultra-HD Blu-ray Disc parameters (overrides any other settings). * rskip: Enables skipping recursion to analyze lower CU sizes using heuristics at different rd-levels. Provides good visual quality gains at the highest quality presets. * rc-grain: Enables a new rate control mode specifically for grainy content. Strictly prevents QP oscillations within and between frames to avoid grain fluctuations. * tune grain: A fully refactored and improved option to encode film grain content including QP control as well as analysis options. * asm: ARM assembly is now enabled by default, native or cross compiled builds supported on armv6 and later systems. Misc * An SSIM calculation bug was corrected - soname bump to 87. - Fixed arm.patch. - Added libnuma-devel as buildrequires for arch x86_64 (except for openSUSE 13.1 because libnuma-devel >= 2.0.9 is required). ------------------------------------------------------------------- Wed Feb 3 13:22:42 UTC 2016 - ismail@i10z.com - Update to version 1.9 API Changes: * x265_frame_stats returns many additional fields: maxCLL, maxFALL, residual energy, scenecut and latency logging * --qpfile now supports frametype 'K" * x265 now allows CRF ratecontrol in pass N (N greater than or equal to 2) * 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. * --limit-modes: Intelligently restricts mode analysis. * --max-luma and --min-luma for luma clipping, optional for HDR use-cases * Emergency denoising is now enabled by default in very low bitrate, VBV encodes Presets and Performance: * Recently added features lookahead-slices, limit-modes, limit-refs have been enabled by default for applicable presets. * The default psy-rd strength has been increased to 2.0 * Multi-socket machines now use a single pool of threads that can work cross-socket. ------------------------------------------------------------------- Fri Nov 27 18:21:04 UTC 2015 - aloisio@gmx.com - Update to version 1.8: API Changes: * Experimental support for Main12 is now enabled. Partial assembly support exists. * Main12 and Intra/Still picture profiles are now supported. Still picture profile is detected based on x265_param::totalFrames. * Three classes of encoding statistics are now available through the API. + x265_stats - contains encoding statistics, available through x265_encoder_get_stats() + x265_frame_stats and x265_cu_stats - contains frame encoding statistics, available through recon x265_picture * --csv * x265_encoder_log() is now deprecated * x265_param::csvfn is also deprecated * --log-level now controls only console logging, frame level console logging has been removed. * Support added for new color transfer characteristic ARIB STD-B67 New Features: * limit-refs + This feature limits the references analysed for individual CUS. + Provides a nice tradeoff between efficiency and performance. + aq-mode 3 * 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 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
