"Adaptive streaming" allows changing video parameters mid-stream at IDR
boundaries. Such changes require new SPS and PPS NALs at the IDR. MP4
supports this with 'avc3' and 'hev1' sample entry types.

Builds x265 three times, once for each bit depth. Then merges the static libs into one library that HandBrake can statically link against.

...for what not to do. There's more of course. *sigh*

* Remove Fontconfig on Windows
Let libass use its DirectWrite font provider backend instead of Fontconfig.
This eliminates Fontconfig's font cache generation delay that occurred
at the start of an encode after a system font was (un)installed or when
HandBrake was installed and used to burn text subtitles for the first time.
* Remove LibHB's dependency on Fontconfig when it's not used
|
| |
|
|
|
| |
HarfBuzz uses Fontconfig only in command-line utilities, which we don't need.
|
|
|
|
|
| |
Option --with-fcpath does not exist and never did.
We had a patch that added it, but the patch has been removed.
Use the standard option instead.

* x265: bump to version 2.2
Encoder enhancements
----------------------------------
1. Enhancements to TU selection algorithm with early-outs for improved
speed; use --limit-tu to exercise.
2. New motion search method SEA (Successive Elimination Algorithm)
supported now as –me 4
3. 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.
4. Enabled using VBV constraints when encoding without WPP.
5. All param options dumped in SEI packet in bitstream when info
selected.
6. x265 now supports POWERPC-based systems. Several key functions also
have optimized ALTIVEC kernels.
API changes
-------------------
1. Options to disable SEI and optional-VUI messages from bitstream made
more descriptive.
2. New option --scenecut-bias to enable controlling bias to mark
scene-cuts via cli.
3. Support mono and mono16 color spaces for y4m input.
4. --min-cu-size of 64 no-longer supported for reasons of visual quality
(was crashing earlier anyways.)
5. API for CSV now expects version string for better integration of x265
into other applications.
Bug fixes
--------------
1. Several fixes to slice-based encoding.
2. --log2-max-poc-lsb‘s range limited according to HEVC spec.
3. Restrict MVs to within legal boundaries when encoding.
* x265: bump to version 2.3
Encoder enhancements
----------------------------------
1. New SSIM-based RD-cost computation for improved visual quality,
and efficiency; use --ssim-rd to exercise.
2. Multi-pass encoding can now share analysis information from prior
passes (in addition to rate-control information) to improve performance
and quality of subsequent passes; to your multi-pass command-lines that
use the --pass option, add --multi-pass-opt-distortion to share
distortion information, and --multi-pass-opt-analysis to share other
analysis information.
3. A dedicated thread pool for lookahead can now be specified with
--lookahead-threads.
4. --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.
5. The number of bits used to signal the delta-QP can be optimized with
the --opt-cu-delta-qp option; found to be useful in some scenarios for
lower bitrate targets.
6. 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
-------------------
1. Reconfigure API now supports signalling new scaling lists.
2. x265 application’s csv functionality now reports time (in milliseconds)
taken to encode each frame.
3. --strict-cbr enables stricter bitrate adherence by adding filler bits
when achieved bitrate is lower than the target; earlier, it was only
reacting when the achieved rate was higher.
4. --hdr can be used to ensure that max-cll and max-fall values are
always signaled (even if 0,0).
Bug fixes
--------------
1. Fixed incorrect HW thread counting on MacOS platform.
2. Fixed scaling lists support for 4:4:4 videos.
3. Inconsistent output fix for --opt-qp-pss by removing last slice’s
QP from cost calculation.
4. VTune profiling (enabled using ENABLE_VTUNE CMake option) now also
works with 2017 VTune builds.
