Changes:
fix support for sound in PPAPI plugin
better handling of obfuscated code
new command line argument to ignore unhandled exceptions
support for context menus added
partial support for CubeTextures and compressed Textures in Stage3d
ability to create screenshot added
boost dependency removed
fullscreen mode implemented
better sound handling, especially for AVM1
better support of older (AVM1) swf files
support for xml in AVM1
support for video streaming in AVM1
A bunch of packages had an extra "p" specification character passed to
the pax -p option. One is enough. Committed to reduce the human parsing
costs, should someone else need to examine this. (In my case because it
seems recent Linux distros have changed such that some -p arguments can
now cause an error to occur, where previously they were accepted.)
Changes between 3.0.11 and 3.0.11.1:
----------------------------------
Demux:
* Fixed HLS playlist update mechanism, unable to start
in some cases.
* Because of broken HLS servers, adaptive no longer
considers Content-Type as authoritative.
* Fixed handling of WEBM WebVTT subtitles
* Workaround invalid ADTS in TS from Makito encoders
* Fixed Opus when using avformat demuxer
Decoders:
* Fixed inverted explicit start/end positioning
Service Discovery:
* Fix listing of media on certain Panasonic recorders discovered via UPnP
macOS:
* Fix automatic playback resume with "Music" app
* Fix possible freeze after pause, seek, unpause
Version 0.4.2
-------------
- Improved X11/Wayland detection.
- Changed ALSA input to use non-blocking API. This seems to reduce the latency in some cases.
- Added support for s24, s32 and f32 sample formats for ALSA input.
- Added 'open folder' button after saving the recording.
- Several minor improvements.
If you have an obscure multimedia file which needs a 32-bit binary
Windows codec to play you're probably better off converting it in
a VM these days.
While here, delint.
2020-10-25: Version 1.2.1
- Add initial support for .fmts files.
- Improve missing/broken playlist handling ("Star Trek Beyond 4K").

- Fix sign extended bytes when reading single bytes in BDJ.
- Fix creating organization and disc specific BD-J BUDA directories.
- Use external libudfread when available.
- Rename list_titles to bd_list_titles and add it to installed programs.
Release 0.15.0
Boo! Three long years in the making due to large internal changes, this long-awaited release brings bug fixes, speed, and a new mechanism for opting into VSFilter-incompatible features:
Fix backwards/VSFilter-incompatible font sizes with FreeType 2.10+
Improve speed via better caching
Require HarfBuzz unconditionally to ensure good shaping for complex scripts
ass_set_use_margins(true) now simply places text on the whole screen instead of attempting to tie it to video positioning (set by the margin values) and failing in various ways when margins are used to implement pan & scan in a video player
Add ass_track_set_feature() & catch-all ASS_FEATURE_INCOMPATIBLE_EXTENSIONS
Add ASS_FEATURE_BIDI_BRACKETS to enable Unicode 6.3+ bracket matching when applying the Unicode Bidirectional Algorithm (incompatible with VSFilter; requires libass built with FriBidi 1.0+)
Fix stack overflow on deeply nested \t tags
Fix positioning of events with leading line breaks
Fix small but nonzero \bord becoming \bord0 (regression in 0.14.0)
Measure BorderStyle=4 box padding from glyph border, not from glyph fill
Scale everything from script resolution if storage size is not set (including borders and shadows regardless of ScaledBorderAndShadow)
Fix the default aspect ratio calculation when neither 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
Avoid some integer overflows
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
- Make lines stack more like they do in VSFilter
- Default ScaledBorderAndShadow to 0 (like VSFilter), except for subtitles that were produced by old FFmpeg/Libav
- Make shadow positioning with 3D transforms match VSFilter’s
- Cut out glyphs from border & shadow in all the same cases as VSFilter
- Match VSFilter on animated color tags with negative acceleration
- Fix parsing of some files that VSFilter accepts but libass didn’t by ignoring leading whitespace in each line of an ASS file or CodecPrivate
- Improve font selection with CoreText
- Stop faux-bolding fonts that are too bold to get faux bold in VSFilter
- Ignore leading/trailing spaces when calculating height of nonblank lines
- Match VSFilter on \fade with large alpha value arguments
- Stop splitting bitmaps on font substitution
- Multiple fixes for Banner and Scroll effects

Adobe Security Bulletin
Security updates available for Adobe Flash Player | APSB20-58
Summary
Adobe has released security updates for Adobe Flash Player for
Windows, macOS, Linux and Chrome OS. These updates address a critical
vulnerability in Adobe Flash Player. Successful exploitation could
lead to an exploitable crash, potentially resulting in arbitrary code
execution in the context of the current user.
Version 51.0.0 "I Wish" 2020-10-04
New features and enhancements
* mkvmerge, mkvpropedit, MKVToolNix GUI: IETF BCP 47 language tags: added
missing support for UN M.49 regions for which there are no corresponding ISO
3166 alpha codes. This enables language tags such as `es-419` = Spanish in
Latin America and the Caribbean.
* MKVToolNix GUI: IETF BCP 47 language tags: the text in the widget displaying
the current language & the corresponding edit button is now displayed like a
link (depending on the theme: different color & underlined), making it
clearer that not just the edit button can be clicked but the text, too.
Bug fixes
* mkvmerge: AV1 parser: fixed mkvmerge crashing after uncaught exceptions due
to certain data conditions. Found by fuzzying.
* mkvmerge: AV1 packetizer: the duration of frames wasn't set properly. When
appending AV1 IVF or OBU files this meant that the last frame of the Nth
file and the first frame of file N+1 had the same timestamp.
* mkvmerge: DTS reader: fixed handling of buffers with an odd length when
byte-swapped DTS is detected so that mkvmerge doesn't abort with a failed
assertion. Found by fuzzying.
* mkvmerge: h.264/AVC and h.265/HEVC elementary stream readers: mkvmerge will
no longer claim to recognize data that looks like AVC or HEVC but with
invalid video width/height values as that lead to failed assertions in
libEBML later. Found by fuzzying.
* mkvmerge: h.265/HEVC parser: fixed mkvmerge aborting after uncaught
exceptions due to certain data constellations found by fuzzying.
* mkvmerge: IVF reader: fixed mkvmerge crashing with a "division by zero"
error due to certain data conditions. Found by fuzzying.
* mkvmerge: fixed mkvmerge aborting with a "division by zero" error due to the
timestamp scaling factor being 0 after handling certain data constellations
found by fuzzying.
* mkvmerge: track statistics: fixed a "division by zero" error when the
content's shorter than 1ms. Found by fuzzying.
* mkvmerge, mkvinfo, mkvextract, mkvpropedit: Matroska access class: fixed an
invalid memory access under certain data conditions. Found by fuzzying.
* MKVToolNix GIU: IETF BCP 47/RFC 5646 language tags: the GUI will no longer
open the language dialog when clicking on a disabled language display
widget.
* MKVToolNix GUI: IETF BCP 47 language tags: the "variants" combo-boxes were
not populated even when the language tag was valid and contained at a
variant.
* MKVToolNix GUI: IETF BCP 47 language tags: when no language is selected, at
least one of the other components (extended subtags, region, or variants)
has something selected and "private use" is not empty, the GUI would claim
this to be a valid tag, which it isn't.
* MKVToolNix GUI: multiplexer: when the tracks/chapters/tags selection changes
from "at least one entry selected" to "no entry selected", the input
controls will be reset to their default state and not just disabled.
Build system changes
* `configure` now checks for the presence of the a system-wide installed copy
of the JPCRE2 C++ wrapper library for the PCRE2 library and uses that if
it's new enough (at least v10.32.1). If not, the bundled version will be
used as a fallback.

Version 50.0.0 "Awakenings"
New feature: IETF BCP 47 language tags
* I've written up a [nice FAQ
entry](https://gitlab.com/mbunkus/mkvtoolnix/-/wikis/Languages-in-Matroska-and-MKVToolNix)
about the switch to using IETF BCP 47 language tags, how they interact with
legacy language elements, how the programs actually behave and how to
disable their use if necessary.
* mkvmerge: IETF BCP 47/RFC 5646 language tags: mkvmerge will now accept full
BCP 47 language tags for all options taking a language. mkvmerge will always
write "LanguageIETF" track header elements. If the language tag contains a
valid ISO 639-2 language code it will also set the legacy "Language" track
header element to the included ISO 639-2 code.
* mkvmerge: IETF BCP 47/RFC 5646 language tags: if present the "LanguageIETF"
track header element will be reported as the `language_ietf` property in
JSON identification mode.
* mkvmerge: IETF BCP 47/RFC 5646 language tags in chapters: mkvmerge will now
write "ChapLanguageIETF" elements when creating chapter atoms, either when
reading the simple chapter format or when generating chapters due to the
`--generate-chapters` command line option.
* mkvmerge: IETF BCP 47/RFC 5646 language tags in tags: mkvmerge will now
write "TagLanguageIETF" elements when creating "simple tag" elements, either
when reading tag XML files or when generating them.
* mkvmerge: IETF BCP 47/RFC 5646 language tags: added an option
`--disable-language-ietf` that causes mkvmerge to only write the legacy
language elements.
* mkvmerge, mkvpropedit, MKVToolNix GUI's chapter editor: IETF BCP 47/RFC 5646
language tags in chapters: when reading XML chapter files the programs will
now add "ChapLanguageIETF" elements for atoms that don't contain them. The
values are derived from existing "ChapterLanguage" elements.
* mkvpropedit: IETF BCP 47/RFC 5646 language tags: setting/deleting the track
language now acts on both the old language element as well as the
"LanguageIETF" track header element.
* mkvpropedit: IETF BCP 47/RFC 5646 language tags: added an option
`--disable-language-ietf` that causes mkvpropedit to apply changes to the
`language` track header property only to the legacy language track header
element.
* mkvinfo: IETF BCP 47/RFC 5646 language tags: added support for the
"LanguageIETF" track header element.
* MKVToolNix GUI: multiplexer: added full support for IETF BCP 47/RFC 5646
language tags for both track and chapter languages.
* MKVToolNix GUI: chapter: added full support for IETF BCP 47/RFC 5646
language tags for chapter languages.
* MKVToolNix GUI: header editor: added full support for IETF BCP 47/RFC 5646
language tags for track header languages. The header editor allows editing
of the legacy language elements and the IETF BCP 47 language elements
independent of each other.
Other new features and enhancements
* mkvmerge: the chapter generation mode `when-appending` now also works with
the splitting modes `parts:` & `parts-frames:` when using the `…,+…` syntax
for appending other sections of the source file to the same destination
file.
* MKVToolNix GUI: multiplexer: the file selection dialogs now include the
extension `.dtsma` for DTS files.
* mkvmerge: MP4 reader: sped up parsing MP4 DASH files with a lot of segments
(`trun` atoms) quite a bit.
* The PCRE2 regular expression library is now used instead of `std::regex` for
big performance improvements in all places where regular expressions are
used for parsing big chunks of text, e.g. in the subtitle parsers.
* all programs: Windows: all programs now support long file names on Windows
10 release 1604 if they're turned on in the registry.
Bug fixes
* MKVToolNix GUI: preferences: under certain conditions changing the selected
entry in the page tree on the left did not cause the page shown on the right
to be updated.
* mkvmerge: splitting text by a fixed string (e.g. `,`) is now done by using
`std::string.find()` instead of using a regular-expression-based text
splitting function, greatly improving its performance.
* mkvmerge: mkvmerge will now read-buffer file I/O when probing text file
formats which increases its speed significantly on Windows.
* mkvmerge: MP4 reader: fixed handling of `tkhd` atoms of version 1.
Build system changes
* The PCRE2 library (the 8-bit variant) is now required.
