* MKVToolNix GUI: job queue enhancement: added menu entries for acknowledging both warnings and errors at the same time.
2015-06-24 Moritz Bunkus
* MKVToolNix GUI: merge tool bug fix: if ┬╗automatically set the file title┬л is enabled then the title field will be cleared after all source files have been removed.
* MKVToolNix GUI: new watch jobs tool feature: the first tab showing the output of the current job has been changed to show the output of all jobs that have been run since the GUI's been started. This can be turned off in the preferences so that only the output of the currently running job is shown again. Implements #1263.
* MKVToolNix GUI: merge tool bug fix: fixed a crash when enabling/disabling chapters coming from an appended file. Fixes #1293.
* MKVToolNix GUI: new merge tool feature: added an option to set a directory relative to the first input file as the default output directory. Implements #1261.

* MKVToolNix GUI: enhancement: the ┬╗open file┬л dialogs for the chapter and header editor tools will use the same directory that was last used in the merge tool. Fixes #1290.
2015-06-23 Moritz Bunkus
* MKVToolNix GUI: bug fix: fixed reading the ┬╗default track┬л flag of tracks from added Matroska files. Fixes #1281.
* MKVToolNix GUI: new feature: added a check box to the track/chapters/tags/attachments list. This offers an additional way of toggling the ┬╗mux this┬л state of entries, same as the drop down box on the right and as double-clicking on the item already did. Implements #1277.
* MKVToolNix GUI: merge tool bug fix: when appending files with multiple tracks of a type (e.g. multiple audio tracks) then all tracks of that kind would get assigned to the first track of that kind of the file they're appended to. Now the second audio track from the appended file is appended to the second audio track of the existing file, the third to the third etc. Fixes #1257.
* MKVToolNix GUI: merge tool bug fix: fixed automatic output file name re-generation when the mux status of tracks changes. Fixes #1253.
* MKVToolNix GUI: new feature: added an option for always using the suggested description and not asking the user when adding a job to the queue. Implements #1288.
* MKVToolNix GUI: job queue enhancement: added the shortcut Ctrl+R for the menu entry ┬╗start all pending jobs┬л. Implements #1287.
* MKVToolNix GUI: new feature: added an option to always treat files dragged & dropped external applications as being added circumventing the question what to do with them (add, append or add as additional parts). This option is enabled by default changing the default behavior from release 8.0.0. Implements #1259.
* MKVToolNix GUI: new feature: added an optional action after starting a job or adding one to the queue. This can be either to create whole new settings or to only remove all input files. Implements #1254.
* mmg: bug fix: the deprecation warning will only be shown once. Fixes #1252.
* Installer for Windows: enhancement: associated the .mtxcfg files with MKVToolNix GUI. Implements #1258.

2015-06-22 Moritz Bunkus
* MKVToolNix GUI: new feature: implemented command line handling. You can open configuration files, add files to merge jobs, open files in the chapter or header editors. Implements #1209.
2015-06-21 Moritz Bunkus
* mkvmerge: bug fix: fixed recognition of (E)AC3 audio tracks using a FourCC of ┬╗ec-3┬л. Fixes #1272.
* MKVToolNix GUI: merge tool bug fix: fixed attachments not being merged into the file in certain situations. Fixes #1260.
* MKVToolNix GUI: merge tool bug fix: fixed showing existing attachments present in source files in the ┬╗tracks, chapters, tags and attachments┬л list. Fixes #1256.
* MKVToolNix GUI: merge tool bug fix: the jobs created when appending files were incorrect resulting in an error message from mkvmerge. Fixes #1271.
* mkvpropedit: bug fix: fixed a warning about ┬╗edit specifications resolving to the same track┬л when changing the track properties and setting tags for the same track simultaneously. Fixes #1247.
* MKVToolNix GUI: merge tool bug fix: the output/destination file name is cleared when all files are removed. Fixes #1265.
* MKVToolNix GUI: merge tool bug fix: fixed command line escaping for empty arguments. Fixes #1270.
* MKVToolNix GUI: merge tool bug fix: fixed creating files without a title if one of the input files contains a file title. Fixes #1264.
* MKVToolNix GUI: bug fix: if the job removal policy is set to ┬╗remove even if there were warnings┬л then jobs that were muxed without warnings weren't removed. Fixes #1262.
2015-06-20 Moritz Bunkus
* Build system: fixed inclusion of desktop files for the two GUIs for Debian/Ubuntu packages. Fixes #1255.

_http://www.fosshub.com/MKVToolNix.html

* MKVToolNix GUI: chapter editor enhancement: pressing return will cause the next appropriate chapter control to be selected depending on where the focus currently is: from a chapter input to the first chapter name, from a chapter name to the next chapter name and from the last chapter name to the next chapter entry's start time. Implements #1358.
2015-08-14 Moritz Bunkus
* MKVToolNix GUI: enhancement: the number of running jobs is shown in the status bar. Implements #1381.
* MKVToolNix GUI: new job queue feature: added a context menu for force-starting selected jobs. This allows for running more than one job at the same time. Implements #1395.
* MKVToolNix GUI: new merge tool feature: added an option for automatically setting the В»default trackВ« flag to В»noВ« for all subtitle tracks when they're added. Implements #1339.
2015-08-12 Moritz Bunkus
* MKVToolNix GUI: new merge tool feature: dragging & dropping files onto line edit controls that expect file names (e.g. the В»chapter fileВ« control) will set that line edit's text to the dropped file name. Implements #1344.
* mkvmerge: bug fix: track statistics tags can be kept with the option В»--engage keep_track_statistics_tagsВ«. This allows outputting them in verbose identification mode for easier parsing. Fixes #1351.
2015-08-11 Moritz Bunkus
* MKVToolNix GUI: new feature: jobs in the queue can now be edited again. For that they're re-opened in the corresponding tool and removed from the queue. Implements #1296.
* build system: stack protection is enabled when building with gcc on all platforms. For Windows DEP and ASLR is enabled. Implements #1370.
2015-08-09 Moritz Bunkus
* build system: the Boost detection macros were updated from resulting in better compatibility with bare-bones shells like dash.
* MKVToolNix GUI: enhancement: the format of the setting and queue files has been changed from INI style to JSON documents. Reading older setting files in INI style remains supported, but saving will convert them to JSON.
Together with the other three changes mentioned below this results in a noticeable reduction in the time needed for writing the queue files, e.g. when pressing В»start muxingВ« or when quitting the application.
* MKVToolNix GUI: enhancement: the way the job queue is stored has been changed. Earlier all jobs were stored in the same file (or registry on Windows) as the preferences. Now they're stored in a sub directory called В»jobQueueВ« with one file per queue entry.
* MKVToolNix GUI: enhancement: on Windows the preferences are not stored in the registry anymore, not even if the application has been installed. Instead they're stored in an INI file in the user's AppData\Local directory tree.
* MKVToolNix GUI: enhancement: the number of times the queue files are saved has been reduced. The queue files are also loaded only once on startup, not twice.
* MKVToolNix GUI: bug fix: fixed various crashes when dragging & dropping in all of the tree views (merge tool: files view, tracks view, attachments view; chapter editor: edition/chapter tree, chapter name list; job queue). Fixes #1365.
2015-08-08 Moritz Bunkus
* MKVToolNix GUI: enhancement: if an instance is already running when the application is started a second time then the GUI requests that the already-running instance will be activated. Implements #1379.
* MKVToolNix GUI: new feature: added an option in the preferences for automatically switching to the job output tool whenever the user starts a job (e.g. by pressing В»start muxingВ«). Implements #1376.
* MKVToolNix GUI: new job output and job queue feature: added a function for opening the output folder. Implements #1342.
* MKVToolNix GUI: new job output tool feature: added a way to clear the output, warnings and errors views. Implements #1356.
* MKVToolNix GUI: merge tool bug fix: attachments: sometimes changing values didn't apply the changes to all selected attachments depending on how they were selected. Fixes #1373.
* MKVToolNix GUI: merge tool bug fix: the automatically suggested description for new jobs contained the file name twice, even in the directory portion. Fixes #1378.
* MKVToolNix GUI: merge tool bug fix: if В»set output file name automaticallyВ« is enabled then file names ending with a number in parenthesis (e.g. В»Berlin (1962).mkvВ«) will keep their number in the generated output file name. Fixes #1375.
* MKVToolNix GUI: merge tool bug fix: the GUI will keep manual changes to the output file name even if В»set output file name automaticallyВ« is enabled. Fixes #1372.
* MKVToolNix GUI: bug fix: fixed the stereoscopy drop down box not being re-translated when the GUI language is changed. Fixes #1224.
2015-07-22 Moritz Bunkus
* MKVToolNix GUI: chapter editor bug fix: it was possible to drop chapter entries on the top-level reserved for editions. Fixes #1369.
2015-07-21 Moritz Bunkus
* MKVToolNix GUI: Windows: if the application has been installed then its settings will no longer be saved in the registry but in an INI file in the user's data application folder (e.g. C:\Users\mbunkus\AppData\Local\bunkus.org\mkvtoolnix-gui).
2015-07-20 Moritz Bunkus
* MKVToolNix GUI: merge tool enhancement: added В»Simple OGM-style chapter files (*.txt)В« to the file selection dialog when selecting a chapter file. Implements #1269.
2015-07-18 Moritz Bunkus
* MKVToolNix GUI: bug fix: fixed compilation when building without curl support. Fixes #1359.

Released v9.0.0 "Power to progress".
2016-03-25 Mike
* build system: implemented support for explicit pre-compiled headers for Linux and Mac OS.
2016-03-25 Moritz Bunkus
* Installer: fixed support for silent installation and uninstallation.
2016-03-24 Moritz Bunkus
* mkvmerge: bug fix: fixed two more issues in the conversion of teletext subtitles to SRT subtitles:
1. Packets belonging to pages that don't contain subtitles were used as valid end points for subtitles causing entries to become very short (e.g. 40ms).
2. Sometimes the timestamps of wrong packets were used as entry's start and end points causing start timestamps and durations that were slightly off.
Second part of the fix for #1623.
2016-03-22 Moritz Bunkus
* mkvmerge: MP4/QuickTime reader: audio tracks with the FourCC 'lpcm' are muxed as A_PCM/INT/LIT instead of A_QUICKTIME.
* mkvmerge: bug fix: MP4/QuickTime reader: audio tracks can contain two instances of certain header fields (channel count, bits/sample & channel, sample rate) in the STSD atom: one instance in the version 0 header and one in the version 2 header parts. So far mkvmerge has used those from the version 0 header only and ignored the ones from the version 2 header.
This has been changed to match the behavior of other players and MP4 readers like ffmpeg. If the STSD atom contains a version 2 structure then the fields from it will be used. Otherwise the fields from the version 0 part will be used.
Fixes #1633.
2016-03-21 Moritz Bunkus
* all: new feature: added a new translation of both the programs and the man pages to Korean by Potato (see AUTHORS).
* MKVToolNix GUI: chapter editor enhancement: added a button next to the 'segment UID' controls that enable the user to select a Matroska file. The GUI reads that file's segment UID and enters its value into the input field.
2016-03-20 Moritz Bunkus
* build system: added an option to configure В»--without-qt-pkg-configВ«. Normally configure uses pkg-config for detecting Qt and setting QT_CFLAGS and QT_LIBS. With this option configure won't use pkg-config and rely on the user having set both variables before running configure. This enables using Qt on systems where no pkg-config files are generated (e.g. Qt 5.6.0 on MacOS with frameworks enabled).
2016-03-18 Moritz Bunkus
* mkvinfo: change: on Windows and Mac OS mkvinfo will now launch the GUI by default unless the option В»--no-guiВ« (or В»-GВ«) has been given. This is due to the fact that on both OS users often use portable versions respectively disk images and launch the executable directly and not via start menu entries. In those situations adding command line options for launching the GUI is unnecessarily difficult.
2016-03-16 Moritz Bunkus
* mkvmerge: bug fix: fixed two issues in the conversion of teletext subtitles to SRT subtitles:
1. Consecutive teletext packets with the same content are now merged into a single entry instead of resulting in multiple entries.
2. The calculation of a packet's duration was wrong in certain situations.
Part of the fix for #1623.
2016-03-14 Moritz Bunkus
* MKVToolNix GUI: merge tool (playlist selection dialog) enhancement: the playlist items are sorted by their position within the playlist by default.
* MKVToolNix GUI: merge tool (playlist selection dialog) enhancement: double-clicking on a playlist will select and add that playlist.
2016-03-12 Moritz Bunkus
* mkvmerge: enhancement: added the number of bits per sample to the verbose/JSON identification output for FLAC files.
2016-03-11 Moritz Bunkus
* mkvextract: bug fix: fixed the duplication of VPS, SPS, PPS and SEI NALUs when extracting h.265/HEVC tracks. See #1076 and #1621.
* mkvmerge: bug fix: reverted the patch by VladimГ­r PilnГЅ that made the h.265/HEVC not store SEI NALUs with the frames during muxing. It was supposed to prevent having the SEI NALUs present twice when extracting HEVC due to some SEI information also being stored in the codec private data, but it dropped a lot of other SEI NALUs irrevocably. Fixes #1621.
2016-03-09 Moritz Bunkus
* mkvmerge: bug fix: the --sub-charset option is now ignored for text subtitle files that start with a byte-order mark (BOM) bringing the behavior in line with the documentation. Fixes #1620.
2016-03-07 Moritz Bunkus
* mkvextract: new feature: implemented the extraction of Big Endian PCM (codec ID A_PCM/INT/BIG) to WAV files. The content will be byte-swapped into Little Endian PCM in the process.
* mkvmerge: enhancement: Big Endian PCM tracks will now be byte-swapped into Little Endian PCM, and the codec ID A_PCM/INT/LIT will be used. This was done due to a lot of players not supporting Big Endian PCM inside Matroska.
2016-03-01 Moritz Bunkus
* mkvmerge, MKVToolNix GUI: new feature: added switches (»--generate-chapters« and »--generate-chapter-name-template«) and their corresponding UI items for generating chapters while muxing. Two modes are currently supported: »when-appending« which creates one chapter at the beginning and an additional one each time a file is appended and »interval:…« which generates chapters in fixed intervals.
Implements mkvmerge's and the GUI's part of #1586.
2016-02-28 Moritz Bunkus
* MKVToolNix GUI: job queue enhancement: completed jobs will now be removed from the queue automatically on exit if the job has been added more than 14 days ago in order not to let the queue grow arbitrarily large. This feature can be turned off and the number of days can be adjusted in the preferences.
2016-02-27 Moritz Bunkus
* mkvpropedit, MKVToolNix GUI's header editor: bug fix: fixed the handling of files where the last level 1 element has an unknown size. The programs will now either fix this element to have a known size or abort the process with an appropriate error message but without modifying the file. Fixes #1601.
2016-02-25 Moritz Bunkus
* mkvextract: enhancement: when extracting chapters in the simple format the user can use the new option »--simple-language …« for selecting the chapter names that are output. Normally the first chapter name found in each atom is used. With this option mkvextract looks for a chapter name whose language matches the specified one.
Implements the feature enhancement part of #1610.
* mkvextract: several issues regarding the extraction of chapters in the simple format have been fixed: if multiple names with different languages were present then an entry had been written for each name; the total number of entries written was wrong; the wrong entries were written.
The new code only writes the first name found from the top-most chapter atoms of all editions. Chapters flagged as hidden or as not enabled are not extracted at all.
Fixes the bug part of #1610.
2016-02-24 Moritz Bunkus
* MKVToolNix GUI: new chapter editor feature: added an option to multiply all chapter timecodes by a factor to the "additional modifications" dialog. Implements #1609..

Released v9.0.1 "Obstacles".
* mkvmerge: bug fix: regression in v9.0.0: the text subtitle packetizer was wrongfully assuming an encoding of UTF-8 if none was given instead of assuming the system's encoding. Fixes #1639.
2016-03-27 Moritz Bunkus
* mkvmerge: bug fix: if too many chapters had been generated with --generate-chapters then mkvmerge created a bogus entry in the meta seek element and did not actually write the chapters to the file.
* mkvmerge: bug fix: the DTS packetizer was setting the number of channels wrong sometimes when reducing to the DTS core. It was using the number of channels including the extensions instead of the channels of the core only.

2016-05-20 Moritz Bunkus
* MKVToolNix GUI: merge tool enhancement: the action "select all attached files" in the popup menu actions for the attached files view has been split up into "enable all attached files" and "disable all attached files". Implements #1698.
2016-05-15 Moritz Bunkus
* MKVToolNix GUI: bug fix on Windows: removing the drive letter does not cause the colon to be removed automatically anymore. Fixes #1692.
* MKVToolNix GUI: merge tool bug fix: it's no longer possible to select "1" as the maximum number of files to split into as mkvmerge doesn't accept that value. Fixes #1695.
* mkvmerge: bug fix: the "interval" chapter generation mode was always creating one chapter too many.
* mkvmerge: bug fix: if a certain number of chapters had been generated with --generate-chapters then mkvmerge wasn't replacing the void placerholder with the actual chapters. Fixes #1693.
2016-05-14 Moritz Bunkus
* MKVToolNix GUI: merge tool bug fix: the track column "default track in output" wasn't taking into account if the track had its "default track" flag set to "no" in the source file. This would result in the column showing "yes" in certain situations even though mkvmerge would assign "no".
2016-05-06 Moritz Bunkus
* mkvmerge: bug fix: fixed detection of (E-)AC-3 in MPEG TS files with unusual stream types (e.g. 0x87) but with (E-)AC-3 PMT descriptors. Fixes #1684.
2016-05-05 Moritz Bunkus
* mkvmerge, mkvextract: bug fix: fixed handling of Big Endian PCM with a bit depth other than 16, 32 or 64 bits/sample. Other formats were using the Little Endian codec ID, but their content was actually not byte-swapped to match it. Now those other bit depths are byte-swapped to Little Endian, too. Fixes #1683.
* mkvinfo: the change to start the GUI by default on Windows and Mac OS has been reverted. Instead a separate executable (mkvinfo-gui) will be included for those platforms which starts the GUI by default. The newly introduced option "--no-gui" will remain valid but won't have any effect when used with mkvinfo.
2016-05-04 Moritz Bunkus
* mkvinfo GUI: enhancement: the window title now includes the file name. Implements #1679.
* mkvmerge: enhancement: the "bit depth" track header field will be set for DTS tracks from the first DTS core header. Implements #1680.
2016-05-02 Moritz Bunkus
* mkvmerge: bug fix: the time zone portion of the "date_local" member of the JSON and verbose identification formats contained the time zone's name instead of its offset on Windows due to the Visual C++ runtime's std::strftime not being C++11 compliant.
Additionally this resulted in errors about invalid UTF-8 strings for locales where the time zone's name contained non-ASCII characters.

* Released v9.1.0 "Little Earthquakes".
* mkvmerge: MPEG TS/teletext enhancement: included the teletext page number in the JSON/verbose identification output as track property "teletext_page".
* mkvmerge: MPEG TS bug fix: the "text_subtitles" property of the JSON/verbose identification modes was always set to true for all subtitle tracks, even for those that aren't text subtitles (VobSub, PG).
* mkvmerge: MPEG TS/teletext enhancement: if a teletext track contains multiple teletext pages then mkvmerge will now recognize all of those pages as separate tracks to merge instead of only merging the first page. See #1662.
2016-04-21 Moritz Bunkus
* mkvmerge: MPEG TS/teletext enhancement: mkvmerge will now ignore obviously bogus PTS values for teletext tracks and use PTS from earlier audio or video packets instead. See #1662.
2016-04-20 Moritz Bunkus
* mkvmerge: MPEG TS/teletext bug fix: the language code signaled in the MPEG TS PMT is taken into account when selecting the character encoding to use during decoding of the teletext subtitles, not just the "national character set" stored in the teletext page headers. For example, a German teletext page may signal "national character set" 0 (English) whereas it's actually 4 (German). See #1662.
* mkvmerge: teletext decoding bug fix: fixed dropping of certain non-ASCII characters in rare circumstances due to wrong filtering of already UTF-8 encoded strings.
* mkvmerge: MPEG TS reader enhancement: teletext tracks of type 5 (hearing impaired) are recognized as subtitles, too. Implements #1662.
2016-04-16 Moritz Bunkus
* MKVToolNix GUI: merge tool enhancement: characters that aren't valid in path names are automatically removed from the output file name. Implements #1647.
* MKVToolNix GUI: bug fix (Windows only): the GUI didn't start if the USERNAME environment variable contained characters that aren't allowed in file names (e.g. : or ?).
2016-04-13 Moritz Bunkus
* mkvmerge: AVI reader bug fix: fixed reading files where the file ends in the middle of an audio chunk. Fixes #1657.
2016-04-11 Moritz Bunkus
* mkvextract: new feature: added support for extracting WebVTT subtitles. Implements the extraction part of #1592.
* mkvmerge: new feature: added support for reading WebVTT subtitles from WebVTT and Matroska files. Implements the merge part of #1592.
* mkvmerge: enhancement: when reading Matroska files not created by mkvmerge that contain chapters the existing edition UIDs and chapter UIDs are removed and random ones created. This is necessary as not only HandBrake but other tools assign sequential numbers starting at 1 for each file. Therefore there are two chapter entries with the UID 1, two with the UID 2 etc. and those should, strictly speaking, be treated as if they were a single chapter whereas the user expects those entries to stay separate entries.
2016-04-09 Moritz Bunkus
* MKVToolNix GUI: new feature: added an option in the preferences ("Merge" → "Output") for controlling whether or not the GUI clears the "output file name" input upon removal of the last file.
* MKVToolNix GUI: new feature: added an option in the preferences ("Merge" → "Default values") for controlling whether or not the GUI clears the "file title" input upon removal of the last file.
* mkvmerge: bug fix: mkvmerge will no longer abort reading a Matroska file with a structural error right before the first cluster. Fixes #1654.
2016-04-03 Moritz Bunkus
* mkvmerge: enhancement: added the muxing date in both local time zone and UTC to verbose/JSON identification outputs (keys "date_local" and "date_utc", formatted after ISO 8601) when identifying Matroska files.
2016-04-02 Moritz Bunkus
* mkvmerge: enhancement: added the minimum timestamp for each track in verbose/JSON identification outputs (key "minimum_timestamp") when identifying Matroska files. At most the first ten seconds are probed; if no block is found for a track within that range then the key is not output for the track.
Also added "muxing_application" and "writing_application" to the "container" section of the output. Currently those are only set for Matroska files.
2016-03-31 Moritz Bunkus
* MKVToolNix GUI: merge tool change: attachments from source files have been moved from the "Tracks, chapters, tags and attachments" list on the "sources" tab to a new list on the "attachments" tab. That way all existing attachments and all the ones to newly add will be shown in a single tab. This makes it easier to decide which attachments will have to be added and which can be removed.
* MKVToolNix: merge tool bug fix: when adding playlists the GUI won't ask the user whether or not to scan if there's only a single playlist in that directory.
2016-03-29 Moritz Bunkus
* mkvmerge: bug fix: AVC/h.264: fixed handling of interlaced frames with bottom field first.
* MKVToolNix GUI: bug fix: fixed huge memory consumption (e.g. allocation of 2 GB for a JSON file of 650 KB) in the JSON library by updating said JSON library. Fixes #1631.

* Note: most of the bugs fixed on 2016-09-06 and 2016-09-07 for issue #1780 are potentially exploitable. The scenario is arbitrary code execution with specially-crafted files. Updating is highly recommended.
* mkvmerge: bug fix: AVC & HEVC readers: the readers will now refuse to handle files where the detected pixel width or height is equal to or less than 0. Before this fix the muxing process aborted with an assertion inside libMatroska. Fixes the last test case of #1780.
* mkvmerge: bug fix: HEVC parser: fixed another invalid memory access (beyond the end of allocated space). Fixes two test cases of #1780.
