Download MKVToolnix 6.3.0

MKVToolNix has been updated to version 6.3.0. MKVToolNix is ​​a collection of open source programs that allow viewing, editing, and conversion of Matroska files. For example, sound tracks and subtitles can be added, removed or set as default. They are separate command line tools, but a graphical user interface is included. Versions are available for download for Windows, many Linux distributions, and OS X. This release includes the following changes and improvements:

Changes in version 6.3.0:

• mkvmerge: bug fix: When appending unframed AVC/h.264 tracks and setting the default duration the second and all following source parts will use the same default duration as set for the first part. Fix #889.
• all: enhancement (Windows only): mmg will store its settings in a file “mkvtoolnix.ini” in the same folder mmg.exe is located in if MKVToolNix hasn’t been installed via its installer. If it has been installed then the settings are stored in the Windows registry. This way MKVToolNix is ​​truly portable.
• mmg: new feature: mmg’s windows and dialogs will remember and restore their positions and sizes. Implementation #878.
• mkvmerge: bug fix: AVC/h.264 output module: fixed writing the wrong values ​​if –fix-bitstream-timing-information is used. Fixes #888.
• mkvmerge: bug fix: FLV reader: Implemented deriving the video dimensions for FLV1 type tracks from the frame content if they’re not given within a script tag. Fix #880.
• mkvmerge: bug fix: Fixed handling MPEG transport streams with broken PES packet streams. Fixes #879 and #887.
• mkvextract: bug fix: mkvextract writes the correct value for the “block alignment” value in the header of WAV files (mostly affects mono PCM audio tracks). Fix #883.
• all: new feature: added a Portuguese translation of the programs by Ricardo Perdigão (see AUTHORS).
• Added new builds for Windows (6.3.0-1): same source, but built against a different version of the wxWidgets library in order to circumvent a bug in the library.
