I’ve released MKVToolNix v8.4.0. It contains numerous bug fixes in the GUI and even more new features and enhancements. For this release considerable work has gone into mkvmerge again as well fixing a couple of bugs and implementing some more small enhancements.

The most noticeable change is that the old GUI (mmg) has finally been removed.

Changes for package maintainers: the most important change is that the old GUI (mmg) has been removed. Therefore wxWidgets isn’t used anymore. If Qt 5.2.0 or newer is present then mkvinfo’s Qt GUI will be built autoamtically, as will be the MKVToolnix GUI.

You can download the source code or one of the binaries.

Here’s the full ChangeLog since the previous release:

• 2015-09-19 Moritz Bunkus <moritz@bunkus.org>
  • Released v8.4.0.
  • MKVToolNix GUI: chapter editor bug fix: whenever the additional modification of »expanding start/end timecodes to include the minimum/maximum timecodes of their children« was run on an edition entry then ChapterTimeStart and sometimes ChapterTimeEnd nodes were inserted as direct children of the EditionEntry node when saving. This resulted in invalid chapters.
• 2015-09-18 Moritz Bunkus <moritz@bunkus.org>
  • MKVToolNix GUI: new merge tool feature: when dragging & dropping files onto merge settings already containing a file the user can set more options to be always done instead of asking (before: only adding files to the current merge settings could be thus marked; now: adding to current, adding to new settings and adding each file to new settings can be set to perform without asking). Implements #1388.
  • MKVToolNix GUI: merge tool enhancement: when dragging & dropping files onto merge settings already containing a file the dialog asking the user what to do has received a new option for creating one new merge tab for each of the dropped files. Implements #1380.
• 2015-09-17 Moritz Bunkus <moritz@bunkus.org>
  • mkvmerge: bug fix: the pixel dimensions reported for VC-1 in MPEG transport streams in verbose identification mode was 0x0.
  • mkvmerge: bug fix: the number of channels and the sample rate reported for DTS in MPEG transport streams and MPEG program streams in verbose identification mode was 0.
  • mkvmerge: container and track properties in verbose identification mode are now output sorted.
  • MKVToolNix GUI: new merge tool feature: the »tracks« tree view contains a new column titled »properties« which contains basic track properties: the pixel dimensions for a video track and sampling frequency, number of channels and bits per sample for an audio track. Implements #1295.
• 2015-09-14 Moritz Bunkus <moritz@bunkus.org>
  • mkvmerge: enhancement: the verbose identification result for all audio tracks has been extended to include the number of channels, the sample rate and the bits per sample where applicable. Part of the implementation of #1295.
• 2015-09-13 Moritz Bunkus <moritz@bunkus.org>
  • all: bug fix: parsing of strings containing negative values or timecodes was broken on 32bit architectures. Fixes #1425.
• 2015-09-06 Moritz Bunkus <moritz@bunkus.org>
  • mkvmerge: the verbose identification result for the MPEG program stream, MPEG transport stream and WAV readers has been changed for audio tracks in order to match the Matroska reader’s result. The old keys »channels«, »sample_rate« and »bits_per_sample« have been replaced by »audio_channels«, »audio_sampling_frequency« and »audio_bits_per_sample«.
  • mkvmerge: enhancement: the pixel width/height will be reported in verbose identification mode for all video tracks.
• 2015-09-05 Moritz Bunkus <moritz@bunkus.org>
  • MKVToolNix GUI: new merge tool feature: added a column in the track list showing the effective state of the »default track« flag. It shows the state of the flag as it will be in the output file. Implements #1353.
• 2015-09-02 Moritz Bunkus <moritz@bunkus.org>
  • mkvmerge: enhancement: when mkvmerge encounters garbage data in the middle of AC3 or MP3 tracks it will now output the timecode where the garbage occurred in order to make checking for audio/video sync issues easier. Implements #1420.
• 2015-09-01 Moritz Bunkus <moritz@bunkus.org>
  • MKVToolNix GUI: chapter editor enhancement: added a column in the tree with the edition’s/chapter’s flags.
  • MKVToolNix GUI: new feature: the state of all columns in all list/tree views can be reset (both the shown/hidden state as well as their order) from the column’s context menu. See #1268.
• 2015-08-30 Moritz Bunkus <moritz@bunkus.org>
  • MKVToolNix GUI: new feature: the column headers of all list/tree views can be re-ordered via drag & drop and the GUI will remember their position upon restart. Additionally the columns can be hidden/shown via a context menu by right-clicking on the column headers. Implements #1268.
  • MKVToolNix GUI: new chapter editor feature: added an option for skipping chapters marked as "hidden" in the re-numbering dialog. Implements #1414.
• 2015-08-29 Moritz Bunkus <moritz@bunkus.org>
  • all: new feature: added a new translation to Serbian (Cyrillic) by Jay Alexander Fleming (see AUTHORS).
  • MKVToolNix GUI: enhancement: the header editor will convert ISO 639-2 terminology codes used in language elements to their corresponding bibliographic variants. Implements #1418.
• 2015-08-28 Moritz Bunkus <moritz@bunkus.org>
  • MKVToolNix GUI: merge tool bug fix: if the output file name policy »last output directory« was used then manual changes to the output file name weren’t recognized as changes to the last output directory. Fixes #1411.
  • MKVToolNix GUI: merge tool bug fix: the »default subtitle charset« is not applied to text subtitles from Matroska files as those are always encoded in UTF-8. Fixes #1416.
  • MKVToolNix GUI: enhancement: the titles and button texts of dialogs asking questions have been improved to be easier understandable. For example, instead of using »yes/no« as the answers to the question »Do you want to close the unmodified file?« the choices are now »Close file/Cancel«. Implements #1417.
• 2015-08-27 Moritz Bunkus <moritz@bunkus.org>
  • MKVToolNix GUI: chapter editor bug fix: the »shift timecodes« action in the mass modification dialog wasn’t working at all, and selecting multiple actions in the dialog would result in wrong actions being executed.
• 2015-08-23 Moritz Bunkus <moritz@bunkus.org>
  • MKVToolNix GUI: chapter editor enhancement: when loading simple/ OGM style chapter files that contain non-ASCII characters and which do not start with a byte order mark (BOM) the GUI will let the user chose the character set to use. A preview is shown for the selected character set and updated when the user changes the character set.
• 2015-08-20 Moritz Bunkus <moritz@bunkus.org>
  • MKVToolNix GUI: merge tool enhancement: added »remove all« and »select all« entries to the attachments context menu. Implements #1386.
  • MKVToolNix GUI: job output enhancement: the output, warnings and error text views are now separated by two splitters enabling the user to change their respective sizes. These changes are remembered over restarts. Implements #1394.
  • MKVToolNix GUI: chapter editor enhancement: pressing shift+return will cause the next appropriate chapter control to be selected depending on where the focus currently is: from a chapter input (start/end time, flags, UIDs) to the next chapter entry’s start time, from a chapter name to the next chapter name and from the last chapter name to the next chapter entry’s first chapter name. Implements #1398 and complements #1358.
  • MKVToolNix GUI: chapter editor enhancement: pressing return on the very last chapter entry will wrap and focus the first one in the tree again. Enhances #1358.
• 2015-08-19 Moritz Bunkus <moritz@bunkus.org>
  • MKVToolNix GUI: bug fix: fixed the total job queue progress with respect to removing completed jobs (either automatically or manually). Fixes #1405.
• 2015-08-18 Moritz Bunkus <moritz@bunkus.org>
  • MKVToolNix GUI: bug fix: mkvmerge is now run in with the same interface language set for the GUI.
  • mkvmerge: bug fix: The formula used for calculating the audio delay for garbage data at the start of tracks in AVI files has been fixed again. It now uses the values dwStart, dwScale and dwSampleSize from the AVI stream header structure instead of values derived from the audio packet headers. Fixes #1382 and still works correctly for #1137.
  • MKVToolNix GUI: enhancement: scrolling over input elements like combo boxes, check boxes and radio buttons located within a scroll area will now scroll the scroll area instead of the element the cursor is over (e.g. a combo box). Implements #1400.
• 2015-08-17 Moritz Bunkus <moritz@bunkus.org>
  • all: the environment variable <TOOLNAME>_OPTIONS is now parsed for options for TOOL (e.g. MKVMERGE_OPTIONS for mkvmerge). MKVTOOLNIX_OPTIONS is still used for all programs. Fixes #1403.
• 2015-08-16 Moritz Bunkus <moritz@bunkus.org>
  • MKVToolNix GUI: bug fix: fixed the escaping of the command line for cmd.exe regarding the command name itself (the very first argument). Fixes #1401.
• 2015-08-15 Moritz Bunkus <moritz@bunkus.org>
  • build system: removal: the switch »–without-mkvtoolnix-gui« has been removed. There are only two GUIs left in the package: the Qt-enabled mkvinfo and MKVToolNix GUI. Both are enabled by default and can be disabled with the option »–disable-qt«. In that case only the text-mode version of mkvinfo is built, and the MKVToolNix GUI is not built at all.
  • Removal: all support for wxWidgets has been removed. This means that the mkvmerge GUI (mmg) has been removed and that mkvinfo now only supports a text-mode and a Qt-based interface.
  • build system: bug fix: fixed Qt platform plugin detection on MacOS.

Have fun.
