Sun Mar 19 12:08:09 UTC 2023 - Dirk Müller <dmueller@suse.com>
- update to 0.17.1:
* Fix buffer overread if soft-wrapping occurred and
ASS_FEATURE_WHOLE_TEXT_LAYOUT was enabled via API or due
to Encoding -1
* x86: detect GNU Hurd and configure NASM appropriately
-------------------------------------------------------------------
Wed Dec 7 16:34:47 UTC 2022 - Dirk Müller <dmueller@suse.com>
- update to 0.17.0:
* This releases major feature is the addition of a new ASS ScriptInfo
header pair: LayoutResX and LayoutResY. The introduction has been
coordinated with active VSFilters and will soon be available in xy-
VSFilter and XySubFilter as well.
* Since the beginning, many features in ASS scale relative to or are
otherwise affected by the storage resolution of the video file the subs
are bundled with. Adjusting subs for different video resolutions
traditionally took non-trivial effort. Of course this behavior must be
kept by default to preserve compatibility with existing files. But now,
setting both of the new headers to a positive, non-zero value will
replace the video storage resolution with the specified resolution for
the whole file, allowing easy reuse across all encodes of the same
display aspect ratio. This includes PAR effects, so reuse across
anamorphic and non-anamorphic releases is possible too.
* Detailed Changes:
* Fix various parts relating to automatic linebreaking
* Fix rendering when hinting was enabled and fontsizes or scales are zero
* Switch build to a non-recursive setup for improved parallelism
* Improve quality of SSA Effects movement
* Further documentation improvements
* Completely invalid Events are now discarded during parsing
* Introduction of LayoutRes{X,Y} script headers
* New AlphaLevel style override to set all alpha values while keeping the
color
* Add ASS_FEATURE_WRAP_UNICODE to allow automatic linebreaks in accordance
with the Unicode line breaking algorithm instead of ASS' much stricter
breaking rules. For the feature to be available at runtime, libass must
be linked against the new optional dependency libunibreak.
* Improve VSFilter compatibility:
* Fix premature truncation of animated alphas (was a 0.15.0 regression)
* Fix handling of small delay parameters for legacy SSA Effects
* Fix x-scaling with PlayResX
* Fix x-scaling for anamorphic video (except for \be whose scaling remains
buggy in general)
* Support SSA's AlphaLevel style field
* Support the \kt override tag from VSFilter's v4++ set
* Parse ScriptType headers
* Parse integer header, style and event field values like VSFilter
* Ignore trailing whitespace in an event's text
-------------------------------------------------------------------
Wed May 18 15:21:57 UTC 2022 - Dominique Leuenberger <dimstar@opensuse.org>
- Update to version 0.16.0:
+ Fix crashes with fonts missing Postscript names and without one
being synthesised by the font provider.
+ Fix crashes on negative fontsizes and some overflows.
+ Fix a rare memory leak introduced in 0.13.0.
+ x86: Fix potential buffer over-read by 16 bytes with AVX2
assembly when large tiles are not enabled (the default).
+ x86: Fix PIC flags not being interpreted by the assembler,
breaking the asm-enabled build setup on NetBSD and OpenBSD. On
32-bit x86, if the toolchain requires PIC objects and relies on
compiler defaults to get PIC implicitly, you need to pass
--with-pic to configure to ensure NASM always produces PIC
objects.
+ x86: Fix AVX support not being detected on non-Intel CPUs and
some VMs.
+ x86: Fix CPUID being used on CPUs not supporting the
instruction (<= i486) and the way it is used for CPUs with less
than 7 CPUID-leafs which could lead to crashes due to illegal
instructions.

2.10+
* Improve speed via better caching
* Require HarfBuzz unconditionally to ensure good shaping for
complex scripts

ASS_FEATURE_INCOMPATIBLE_EXTENSIONS

not set (including borders and shadows regardless of
ScaledBorderAndShadow)

ass_set_pixel_aspect() nor ass_set_aspect_ratio() is called
* Multiple fixes for karaoke override tags
* Handle memory allocation failures better:
avoid some crashes and produce images closer to truth

* Add internal infrastructure for regression testing
* Improve VSFilter compatibility:
+ Treat invalid nested \t tags like VSFilter
+ Make \t(T,T,...) at time exactly T use the post-transition
values

stroker)

- Update to 0.13.1
* Much faster duplicate event check in ass_process_chunk.
* Interpret negative timestamp components as actual negative numbers.

* Fix some small memory leaks, potential crashes and bad data uses
-------------------------------------------------------------------

- Update RPM groups
-------------------------------------------------------------------
Sun Nov 22 22:00:00 UTC 2015 - mpluskal@suse.com
- Update to 0.13.0
* Add native font selection backends for OSX (CoreText) and
Windows (DirectWrite). You can now run libass without
fontconfig on these platforms. This fixes problems with
fontconfig behaving badly on these platforms (it could take
minutes to scan all system fonts). Even on Linux, this speeds
up loading of embedded fonts (such as provided by
ass_add_font()). The DirectWrite backend only works on Windows
Vista and later. On XP, fontconfig is still needed. libass can
be compiled with both DirectWrite and fontconfig, and then it
will fallback to fontconfig automatically if DirectWrite is not
available at runtime.
* Add ass_get_available_font_providers() API function.
* Change the 4th parameter of ass_set_fonts(). This now selects
the font provider. This is somewhat backwards compatible with
the old behavior, but if you ever passed values other than 0
or 1, your application might break with this libass release.
* The ass_fonts_update() function now does nothing. It's kept
for backward compatibility only.
* Much faster gaussian blur. This can bring a large speedup with
big blurred signs and such.
* Drop ENCA support
* Bug fixes
+ Fix compilation of the freetype rasterizer (disabled by
default)
+ Fix rendering with some cases of consecutive line breaks
(\N\N).
+ Fix some memory allocation failure checks
+ Avoid system locale dependent behavior by reinventing some
standard C functions
+ Fix rendering errors with strikes (GH #193)
+ MSVC compilation fixes
- Enable harfbuzz and yasm build requires

compatibility
