Thu Apr 27 14:00:00 2017 joerg.lorenzenAATTki.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.

- 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.

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

- 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.

- 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 14:00:00 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 13:00:00 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).
