​

- Update to version 3.4

  New features:

  * Edge-aware quadtree partitioning to terminate CU depth

    recursion based on edge information. --rskip level 2 enables

    the feature and --rskip-edge-threshold denotes the minimum

    expected edge-density percentage within the CU, below which

    the recursion is skipped. Experimental feature.

  * Application-level feature --abr-ladder for automating

    efficient ABR ladder generation. Shows ~65% savings in the

    over-all turn-around time required for the generation of a

    typical Apple HLS ladder in Intel(R) Xeon(R) Platinum 8280

    CPU @ 2.70GHz over a sequential ABR-ladder generation

    approach that leverages save-load architecture.

  Enhancements to existing features:

  * Improved efficiency in 2-pass rate-control algorithm. The

    savings in the bitrate is ~1.72% with visual improvement in

    quality in the initial 1-2 secs.

  Encoder enhancements:

  * Faster ARM64 encodes enabled by ASM contributions from

    Huawei. The speed-up over no-asm version for 1080p encodes @

    medium preset is ~15% in a 16 core H/W.

​

- Support 10 and 12 bit color depths

​

- Update to version 3.0

  New features

  * option:: '--dolby-vision-profile <integer|float>' generates

    bitstreams confirming to the specified Dolby Vision profile.

    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.

  Encoder enhancements

  * Preset: change param defaults for veryslow and slower preset.

    Replace slower preset with defaults used in veryslow preset

    and change param defaults in veryslow preset as per

- Update to version 2.9

  New features:

  * Support for chunked encoding

    + :option:`--chunk-start and --chunk-end`

    + Frames preceding first frame of chunk in display order

      will be encoded, however, they will be discarded in the

      bitstream.

    + Frames following last frame of the chunk in display order

      will be used in taking lookahead decisions, but, they will

      not be encoded.

    + This feature can be enabled only in closed GOP structures.

      Default disabled.

  * Support for HDR10+ version 1 SEI messages.

  Encoder enhancements:

  * Create API function for allocating and freeing

    x265_analysis_data.

    Default disabled.   

    + For 4K main10 high-quality encoding, we are seeing good

      gains; for other resolutions and presets, we don't

      recommend using this setting for now.

  * :option:`--dynamic-refine` dynamically switches between

    different inter refine levels. Default disabled.

    + It is recommended to use :option:`--refine-intra 4' with

      dynamic refinement for a better trade-off between encode

      efficiency and performance than using static refinement.

  * :option:`--single-sei`

    + Encode SEI messages in a single NAL unit instead of

      multiple NAL units. Default disabled.

  * :option:`--max-ausize-factor` controls the maximum AU size

    defined in HEVC specification.

    + It represents the percentage of maximum AU size used.

      Default is 1.

  * VMAF (Video Multi-Method Assessment Fusion)

    + Added VMAF support for objective quality measurement of a

      video sequence.

    + Enable cmake option ENABLE_LIBVMAF to report per frame and

      aggregate VMAF score. The frame level VMAF score does not

      include temporal scores.

    + This is supported only on linux for now.

  Encoder enhancements:

  * Introduced refine-intra level 4 to improve quality.

  * Support for HLG-graded content and pic_struct in SEI message.

​

- Update to version 2.7:

  * New features:

    - option:`--gop-lookahead` can be used to extend the gop

      boundary(set by `--keyint`). The GOP will be extended, if a

      scene-cut frame is found within this many number of frames.

    - Support for RADL pictures added in x265.

    - option:`--radl` can be used to decide number of RADL pictures

      preceding the IDR picture.

​

-------------------------------------------------------------------

Fri Dec 01 16:40:13 UTC 2017 - joerg.lorenzen@ki.tng.de

​

- Update to version 2.6

  New features

  * x265 can now refine analysis from a previous HEVC encode (using

    options --refine-inter, and --refine-intra), or a previous AVC

    encode (using option --refine-mv-type). 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.

  Bug fixes

  * Bug fixes when --slices is used with VBV settings.

  * Minor memory leak fixed for HDR10+ builds, and default x265

    when pools option is specified.

  * HDR10+ bug fix to remove dependence on poc counter to select

    meta-data information.

​

-------------------------------------------------------------------

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.

    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 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).

​

    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.

  * 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

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

- 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.

​

- 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.

​

- 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).
