Version 2.7
New features
1. :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.
2. Support for RADL pictures added in x265.
:option:--radl can be used to decide number of RADL pictures preceding the IDR picture.
Encoder enhancements
1. Moved from YASM to NASM assembler. Supports NASM assembler version 2.13 and greater.
2. Enable analysis save and load in a single run. Introduces two new cli options --analysis-save <filename> and --analysis-load <filename>.
3. Comply to HDR10+ LLC specification.
4. Reduced x265 build time by more than 50% by re-factoring ipfilter.asm.
Bug fixes
1. Fixed inconsistent output issue in deblock filter and --const-vbv.
2. Fixed Mac OS build warnings.
3. Fixed inconsistency in pass-2 when weightp and cutree are enabled.
4. Fixed deadlock issue due to dropping of BREF frames, while forcing slice types through qp file.
Changes between 1.3.1 and 1.3.2:
* Fix bug in dvbpsi_decoder_psi_section_add() set i_last_section_number
* Fix bug in descriptor 0x8a that prevented it from being parsed properly
* Fix bug in descriptor 0x56 generation with multiple teletext page entries
* Fix bug in descriptor 0x41 correct maximum service count
Version 21.0.0 "Tardigrades Will Inherit The Earth"
New features and enhancements
* mkvmerge: track statistics tags: the TagDefault element will not be
written anymore as it was always set to the default value 1
anyway. Implements 2202.
* mkvmerge, MKVToolNix GUI: JSON files can now contain C++-style line comments
outside of strings (e.g. something like this: // this is ignored). Such
comments, even though not part of the official JSON specifications, are now
ignored when reading JSON files.
* MKVToolNix GUI: chapter editor: opening a Matroska file without chapters in
it will now open the file in an empty chapter editor instead of showing an
error message. Implements 2218.
* MKVToolNix GUI: an "info" tool has been added, replacing the functionality
of mkvinfo's GUI. The functionality is not on par yet but will be for
release v22. Implements most of the functionality of 2104.
Bug fixes
* build system: configure was treating --disable-ubsan and
--disable-addrsan the same as --enable-ubsan and
--enable-addrsan.
* build system: an error message is output if a command to execute is not
found instead of silently failing.
* build system: in addition to looking for the gettext C function and
library, configure now also verifies the presence of the msgfmt program
instead of simply relying on it.
* mkvmerge: appending files with additional parts at the same time was broken
if more than one additional part was appended (e.g. when appending files
from DVDs with something like '(' VTS_01_1.VOB VTS_01_2.VOB ')' + '('
VTS_02_1.VOB VTS_02_2.VOB ')'). In such a situation the content from files
VTS_02_1.VOB and VTS_02_2.VOB where laid out in parallel to the content
from the earlier files.
* mkvmerge: FLV reader: a single invalid AAC frame was written for AAC audio
tracks with codec initialization data longer than five bytes.
* mkvmerge: FLV reader: timestamps will be normalized down to 0.
* mkvmerge: MP4 reader: if an AAC track doesn't contain an AAC-specific
decoder configuration in the ESDS portion, then a default decoder
configuration will be generated based on the track's header data instead of
skipping the track.
* mkvmerge: MP4 reader: fixed reading HEVC/h.265 video tracks if they're
stored as Annex B byte streams inside MP4.
* mkvmerge: Ogg Opus reader: mkvmerge will now emit a warning instead of
aborting when it encounters an Ogg Opus page with no data in the
packet.
* mkvmerge, mkvextract: Matroska parser: fixed a segmentation fault that
occurred whenever the first level 1 element after resyncing after an error
in the file structure isn't a cluster.
* mkvmerge, MKVToolNix GUI multiplexer & header editor: fixed a crash during
--enable-addrsan.
* build system: an error message is output if a command to execute is not
* build system: an error message is output if a command to execute is not

occurred whenever the first level 1 element after resyncing after an error
in the file structure isn't a cluster.
* mkvmerge, MKVToolNix GUI multiplexer & header editor: fixed a crash during
file type detection for attachments if MKVToolNix is installed in a path
with non-ASCII characters (e.g. German Umlauts).
* mkvinfo: the --hex-positions parameter did nothing in summary mode.
* mkvinfo: Windows: line endings will be written as \r\n (carriage return &
line feed) again instead of just \n (line feed).
* mkvpropedit: adding track statistics tags: for tracks with content encoding
(compression) mkvpropedit is now accounting the uncompressed number of
bytes, not the encoded (compressed) number of bytes.
* MKVToolNix GUI: multiplexer: the subtitle character set can now be set for
appended subtitle files, too.
* MKVToolNix GUI: multiplexer: when appending, all tracks appended to disabled
tracks will start out disabled, too.
Build system changes
* mkvinfo: the GUI portion has been removed. mkvinfo is now a pure
command-line program again.

Adobe Security Bulletin
Security updates available for Flash Player | APSB18-03
Summary
Adobe has released security updates for Adobe Flash Player for Windows,
Macintosh, Linux and Chrome OS. These updates address critical
vulnerabilities that could lead to remote code execution in Adobe Flash
Player 28.0.0.137 and earlier versions. Successful exploitation could
potentially allow an attacker to take control of the affected system.
Adobe is aware of a report that an exploit for CVE-2018-4878 exists in
the wild, and is being used in limited, targeted attacks against Windows
users. These attacks leverage Office documents with embedded malicious
Flash content distributed via email.
- audacity: GCC 6 wants std namespace, found via <cmath>.
- smpeg2: don't initialise unsigned with "0-1".
- libclucene/strigi: match GCC 6 (and 7, and 8, and 9.)
This change:
- properly enables dvdnav and dvdread support by passing
--enable-dvd{nav,read} via WAF_CONFIGURE_ARGS; they had both remained
disabled so far in spite of the inclusion of their buildlink3.mk files.
- adds a dependency on lcms2 to allow loading ICC profiles;
- bumps PKGREVISION.
LGTM leot@
1.3:
- Add support for avcC and hvcC structures
- Add support for LOAS AAC
- Improve support for RTP
- Use ISO 6937 as default DVB charset
- Ship pkg-config file
Sync player/lua/ytdl_hook.lua with upstream commit
2a0f9fc1588d8bda51a6340197c54285f3f62755 minus hunks that need `on_load_fail'
hook introduced after mpv-0.27.
Bump PKGREVISION.
### 1.12.4
The fourth 1.12 bug-fix release (1.12.4) was released on 7 December 2017.
This release only contains bugfixes and it should be safe to update from 1.12.x.
#### Major bugfixes in 1.12.4
- Dozens of fixes for various issues detected with the help of Google's OSS-Fuzz
project: https://github.com/google/oss-fuzz
Details to be found there in the bug tracker
- Performance regressions with registering debug categories after gst_init()
were fixed
- Regression with seeking back to 0 in souphttpsrc was fixed
- Regression with header rewriting in flacparse was fixed
- Regression with playbin/playsink leaking sinks was fixed
- Inconsistencies with DROPPED/HANDLED handling in pad probe handlers are fixed
- gst_bin_iterate_sorted() always returns sources last now, as documented
- gst_query_writable_structure() will never return NULL, for consistency with events
- Removal of metas from gst_buffer_meta_foreach() works correctly now
- OpenJPEG plugin builds with OpenJPEG >= 2.3
- CDIO plugin builds with CDIO >= 1.0
- gstreamer-vaapi works correctly with libva 1.0
- gst-libav was updated to ffmpeg 3.3.5
- Various fixes for memory leaks, deadlocks and crashes in all modules
- ... and many, many more!
2017-01-04 v1.7.0 "Mandarin Duck"
This release focused on high bit depth performance (10/12 bit) and vp9
encoding improvements.
- Upgrading:
This release is ABI incompatible due to new vp9 encoder features.
Frame parallel decoding for vp9 has been removed.
- Enhancements:
vp9 encoding supports additional threads with --row-mt. This can be greater
than the number of tiles.
Two new vp9 encoder options have been added:
--corpus-complexity
--tune-content=film
Additional tooling for respecting the vp9 "level" profiles has been added.
- Bug fixes:
A variety of fuzzing issues.
vp8 threading fix for ARM.
Codec control VP9_SET_SKIP_LOOP_FILTER fixed.
Reject invalid multi resolution configurations.
libdvdnav (6.0.0)
* fix crashes on some DVD on describe_title call
* fix various crashes related to PGC validity
* fix compilation issues
* fix API return codes
libdvdread (6.0.0)
* restrict the number of symbols to be exposed to the shared-object
* remove dvdinput_error function
* improve compatibility with some DVDs (notably the eOne ones)
* fix write after free in ifoFree functions
* fix possible buffer overflow in open
* additional checks on DVDReadBytes arguments
* fix leaks
Version 20.0.0 "I Am The Sun":
Important notes
* Feature removal: several deprecated features have been removed:
* mkvmerge: the deprecated options --identify-verbose (and its counterpart
-I), --identify-for-gui, --identify-for-mmg and
--identification-format verbose-text
* all command line tools: support for the deprecated, old, proprietary format
used for option files
* all command line tools: support for passing command line options via the
deprecated environment variables MKVTOOLNIX_OPTIONS, MKVEXTRACT_OPTIONS,
MKVINFO_OPTIONS, MKVMERGE_OPTIONS and MKVPROPEDIT_OPTIONS
* mkvinfo: most of its code was re-written in order to lay the groundwork for
including its functionality in MKVToolNix GUI but with more features than
the existing mkvinfo GUI. The result is that a lot of its output has been
changed slightly while keeping the basic layout. Changes include but aren't
limited to:
* Several element names are a bit clearer (e.g. Maximum cache instead of
MaxCache).
* All timestamps and durations are now output as nanoseconds in formatted
form (e.g. 01:23:45.67890123). All additional formats (e.g. floating
point numbers output in seconds or milliseconds) were removed.
* Element names for chapters and tags are now translated if a translation is
available.
* Elements located in wrong positions within the Matroska document are
handled better.
While mkvinfo's output is mostly kept very stable, it is not designed to be
parsed by other utilities. Even though I've tried hard to cram all changes
and cleanups into this version, additional changes may be made in the next
couple of releases depending on user feedback and bug reports.
New features and enhancements
* mkvmerge: AVC/h.264 packetizer (framed): access unit delimiter NALUs will
now be removed.
Bug fixes
* mkvmerge: AVC/h.264 parser: when fixing the bitstream timing information
mkvmerge will now use exact representations of the desired field duration if
possible. For example, when indicating 50 fields/second num_units_in_tick
is set to 1 and time_scale to 50 instead of 5368709 and 268435456.
* mkvmerge: AVC/h.264 parser: mkvmerge no longer assumes that encountering
sequence parameter set or picture parameter set NALUs signal the start of a
new frame.
* mkvmerge: AVC/h.264 packetizer (framed): when mkvmerge is told to fix the
bitstream timing information, it will now update all SPS NALUs, not just the
ones in the AVCC.
* mkvmerge: MPEG TS reader: TS packet payloads will only be treated as PES
packets if the payload actually starts with a PES start code. The prior
behavior led to wrong timestamps and potentially broken frame data.
* mkvmerge: MPEG TS reader: mkvmerge will now drop incomplete PES packets as
soon as an error is detected in the transport stream instead of passing the
incomplete frame to the packetizer. An error is assumed either if the
transport_error_indicator flag is set or if the value of the
continuity_counter header field doesn't match the expected value.
* mkvmerge: Opus: when re-muxing Opus from Matroska mkvmerge will now write
"block duration" elements for all block groups where a "discard padding" is
set, too.
* mkvmerge: SRT reader: mkvmerge can now handle SRT files with timestamps
without decimal places (e.g. 00:01:15 instead of 00:01:15.000).
* mkvmerge: read buffer I/O class: the class could get out of sync regarding
the file position of the underlying file I/O class causing wrong data to be
returned on subsequent read operations. One result was that trying to
identifying MPLS files that refer to very short M2TS files caused mkvmerge
to segfault.
* mkvmerge: multiplexer core: if there's a gap in audio timestamps, a new
block group/lace will be started for the first frame after each gap. Before
the fix the frame after the gap was often stored in the previous block group
causing the gap to be in the wrong place: at the end of that block
group.
