MKVToolNix GUI: multiplexer: the “default track flag” column in the track list was missing its icons.

MKVToolNix GUI: multiplexer: when adding files to the multiplexer by running the GUI’s executable with file names as command line arguments, the source directory will be remembered as the “last open directory” again, causing subsequent uses of the “open file” dialog to start in the same directory.

For the time being I’ve switched back to building Windows binaries with gcc 10.2.0. This affected v57 and v58 which were built with gcc versions 10.3.0 and 11.1.0 respectively. Even though the underlying bug hasn’t been identified, the investigation showed that building it with newer versions than 10.2.0 of the mingw/gcc cross-compiler enabled the crashes, while binaries built with 10.2.0 were fine. MKVToolNix GUI: only on 64-bit Windows: under certain conditions, the 64-bit Windows binaries crashed when opening dialog windows.Note that the header editor was not affected. mkvmerge, mkvinfo, MKVToolNix GUI’s info tool: only on Windows: displaying dates before 00:00:00 UTC or after 03:14:08 UTC was broken.The main impact is the MIME types of TrueType & OpenType fonts are now detected correctly. mkvmerge, mkvpropedit, MKVToolNix GUI’s multiplexer & header editor: MIME type detection is now done using Qt instead of the magic library.mkvextract: TTA extraction, only on Windows: fixed removing the temporary file created during extraction.mkvmerge: WebVTT parser: the parser now accepts timestamps with hours larger than 99.mkvmerge: SRT subtitle reader: characters that aren’t valid according to the assumed encoding of the file will now be replaced by the Unicode “Replacement Character” U+FFFD instead of keeping the invalid characters, potentially violating the Matroska specs.build system: fixed compilation with fmt v8.The colors used can be configured in the preferences → “Multiplexer” page → “File & track colors” section. MKVToolNix GUI: multiplexer: added small colored boxes for each file & track in order to indicate from which file each track is read.The option is enabled by default & can be found in the preferences → “Multiplexer” page → “Adding files” section. If a sequence is detected, the only first file will be added while the second and following file names will be appended to the first one. MKVToolNix GUI: multiplexer: added an option for recognizing file name sequences such as 4, 4, 4 when adding multiple files at once.

Files & tracks can still be reordered manually later. The order is: video first followed by audio, subtitles and other types.

MKVToolNix GUI: multiplexer: added an option for sorting files & tracks by track types when adding them to multiplex settings.

MKVToolNix GUI: multiplexer: when adding a Blu-ray playlist without scanning for other playlists the GUI will now look for disc library information & let the user select which one to use if there’s more than one entry.

mkvmerge: WebVTT parser: the parser now follows the specs’ rules for parsing timestamps more closely by being more lenient: it allows arbitrary number of spaces & tabs at the start of the line & around the arrow it allows any number of digits for the hours.

Here are the NEWS since the previous release: New features and enhancements The other Linux binaries are stil being built and will be available over the course of the next couple of hours. The Windows and macOS binaries as well as the Linux AppImage are available already.

You can download the source code or one of the binaries. Several things have changed for packagers, so many that I won’t list them here. There were several nice quality of life improvements to the GUI as well as the usual bug fixes.

Summer’s here, so let’s stay inside & play with a new release of MKVToolNix: v59.
