Heyo!

Time for another release. Again nothing major, just some bug fixing & adding a simple converter from timed-text to Matroska’s simple format (SRT-like).

You can download the source code or one of the binaries. The Windows and macOS binaries as well as the Linux AppImage are available already. The other Linux binaries are stil being built and will be available over the course of the next couple of hours.

Here are the NEWS since the previous release:

New features and enhancements

• mkvmerge: MP4 reader: mkvmerge will now read Timed Text (FourCC tx3g) subtitle tracks & convert them on the fly to Matroska’s simple text subtitle format (S_TEXT/UTF8; text only, no styles). Implements #2208, #2242, #2613, #3000, #3243, #3418 and possibly others.

Bug fixes

• all: switched back to using boost::filesystem functions for creating directories instead of the ones introduced to work around bugs in std::filesystem. The latter didn’t work correctly with UNC paths after the switch to boost::filesystem::path in v74. Fixes #3483.
• mkvmerge: VobSub reader: mkvmerge will now probe the .idx file during VobSub identification even if the .sub file is passed as the source. Avoids mis-detection of the .sub as MPEG program streams. Fixes #3489.
• MKVToolNix GUI: the GUI could abort with an exception on startup while looking for the mkvmerge or mediainfo executables due to inaccessible folders. Fixes #3481.
• MKVToolNix GUI: preferences: when opening the preferences the first time the UI might pre-select the first entry in the list of interface languages if the operating system’s language is not available for MKVToolNix. This might also happen on Linux if e.g. en_GB is set, even though en_US is available. Now English (en_US) will be selected instead. Fixes #3486.
• MKVToolNix GUI: multiplexer: when adding files the GUI has special handling for chapter/tags/segment info files. This is done by comparing their content to certain patterns. This recognition could wrongfully be triggered if any such file was embedded in another file verbatim, e.g. with a chapter XML file attachment in a Matroska file. When trying to add that Matroska file, the GUI would treat it as a chapter file instead of a regular one. This content-based detection was fixed. Fixes #3487.

Other changes

• mkvpropedit, GUI’s header editor: removed support for the deprecated “minimum cache” & “maximum cache” track header elements.

Have fun! 😁

Hey y’all!

MKVToolNix v74 is out. This is another one in a longer line of small-ish bug fix releases. Nothing too earth shattering. Anyway, have fun with it.

You can download the source code or one of the binaries. The Windows and macOS binaries as well as the Linux AppImage are available already. The other Linux binaries are still being built and will be available over the course of the next couple of hours.

Here are the NEWS since the previous release:

New features and enhancements

• mkvmerge: SRT handling: added a hack called --engage keep_whitespaces_in_text_subtitles which disables stripping whitespaces from the start & end of each line of SRT entries during muxing. Part of the implementation of #3470.

Bug fixes

• all: Windows: UNC paths of type \\?\C:\… are supported again by switching back to Boost’s file system library instead of using C++17’s file system library. Fixes #3058.
• mkvmerge: AVC/H.264 & HEVC/H.265 packetizers: when appending tracks the pixel dimensions will be checked & muxing will be aborted if they don’t match. Fixes #3480.
• mkvmerge: file type detection: file types that can be detected unambiguously by their content (e.g. Matroska, MP4, WAV…) will now preferred in the detection order over file types based on their extension. Prevents certain cases of mis-detection, e.g. DTS in WAV but with a file name extension of .dts being detected as the wrong type of DTS. Fixes #3462.
• mkvmerge: SRT handling: whitespaces will now be stripped from the start & the end of each line of each entry, not just from the end of the last line. Part of the fix of #3470.
• mkvextract: SRT extraction: whitespaces will not be stripped from the start & end of the whole entry anymore. Part of the fix of #3470.
• MKVToolNix GUI: multiplexer: when adding multiple files that include certain file types (chapters, segment info and tag files) and when the choice where to add them is “all files to a single new tab”, these certain file types will now be added in the newly added tab as well instead of the current tab that had already been open. Fixes #3469.
• build system: fixed compatibility with Ruby 3.2.0 by using FileTest.exist? instead of File.exists?, Dir.exists? & FileTest.exists? which were removed in that release.

Build system changes

• MKVToolNix is now using & requiring Boost’s “file system” and “system” libraries again instead of C++17’s file system library. This is due to gcc’s library not supporting UNC paths of types \\?\C:\dir\file.ext.

Have fun 😁

Hey y’all!

Even though not much has happened with MKVToolNix over the last six or seven weeks, I’ve decided to finalize the first release of the year, v73. Nothing overly amazing in it.

One note for macOS users that isn’t stated in the NEWS below: this release’s DMG was built with FLAC support again. Sorry for the confusing in the previous version; that was due to build system setup SNAFUs on my end.

You can download the source code or one of the binaries. The Windows and macOS binaries as well as the Linux AppImage are available already. The other Linux binaries are stil being built and will be available over the course of the next couple of hours.

Here are the NEWS since the previous release:

New features and enhancements

• mkvmerge: greatly enhanced the speed of Base64 decoding which is used used e.g. when reading pictures embedded in Ogg or FLAC files or for binary data inside XML chapter & tag files. Even small blocks of data could take unreasonably long.
• mkvmerge: added support for reading HEVC/H.265 video from FLV containers. Implements #3466.

Bug fixes

• mkvmerge: splitting: fixed a typo in the string output in GUI mode regarding the timestamps before which splitting was done. See #3421.
• MKVToolNix GUI: job output: after having run multiple jobs the “Clear output” functionality only reset the visible parts. However, using the “save output” function would also save the output generated before the user used “clear output”. Now only the output after the last use of “clear output” is saved. Fixes #3438.
• build system: when probing for the FLAC library the Ogg libraries will be linked with the compiled test program as well. This fixes detection if the pkg-config settings for FLAC don’t list Ogg & the linker doesn’t find the library automatically (e.g. for my macOS builds). Fixes #3439.

Have fun 😁

Heyo!

here’s MKVToolNix release v72. It fixes quite a lot of bugs, several one of them in the component driving the in-place file modification in mkvpropedit & the GUI’s chapter & header editors. Therefore I urge everyone to update.

You can download the source code or one of the binaries. The Windows and macOS binaries as well as the Linux AppImage are available already. The other Linux binaries are stil being built and will be available over the course of the next couple of hours.

Here are the NEWS since the previous release:

New features and enhancements

• mkvmerge: AV1 parser: the variable-width OBU size field will be re-written with minimal length if it’s encoded longer than necessary.
• mkvmerge: when splitting is active the program will output the timestamps actually used for making the decision when to split. If GUI mode is active, a specially formatted line #GUI#splitting_before_timestamp <timestamp> is output as well. Lines prefixed with#GUI# are suitable for machine parsing, won’t be translated and are guaranteed not to change in format. Implements #3421.
• MKVToolNix GUI: multiplexer: when dragging & dropping directories to the “attachments” tab, the files contained in those directories will be attached. Implements #3410.
• MKVToolNix GUI: info tool: added information about the file (directory, size, modification timestamp) at the top of each tab. Implements #3407.

Bug fixes

• mkvmerge: AV1 parser: fixed the parser completely aborting when parsing the OBU size field fails due to there not being enough data to parse. Instead the parser will remember the last known-good position & restart from there after more data is available. Fixes #3431.
• mkvmerge: HDMV PGS subtitles: reverted the change that implemented a heuristic for detecting bogus timestamps & attempting to fix them. This was done to fix #3268. Unfortunately this affected valid subtitle files with intentional huge gaps in timestamps, e.g. forced subtitle tracks. The heuristic has simply been removed, fixing #3392.
• mkvmerge: Matroska reader: fixed reading files with EBML Void elements before the Matroska Segment element.
• mkvmerge: fixed reversed attachment selection: --attachments !4 would not copy any attachment instead of all attachments but the one with ID 4. Fixes #3427.
• mkvextract: IETF BCP 47/RFC 5646 language tags: mkvextract will now use & prefer IETF BCP 47 track language elements if they’re present. Only affects the VobSub & USF subtitle extraction.
• mkvpropedit, MKVToolNix GUI’s chapter & header editors: updated the list of deprecated Matroska elements. The applications will no longer try to write those elements, even if they’re found in the file to be modified. The programs will no longer abort with error messages such as assertion "false" failed. Fixes #3416.
• mkvpropedit, MKVToolNix GUI’s chapter & header editors: when the Matroska version numbers stored in the EBML Head element are updated, the updated EBML Head element might be smaller than the existing one. In that case the programs used to shrink the EBML Head & write a small EBML Void element between the updated EBML Head & the following element, usually a Matroska Segment element. This isn’t widely supported by programs including MKVToolNix itself, causing them to declare such files as invalid. The programs will now create the EBML Void element inside the EBML Head element, making them a level 1 element instead of a level 0 element. Fixes #3355.
• mkvpropedit, MKVToolNix GUI’s chapter & header editors: often the programs have to relocate the Master elements in which the modifications were done. In that case the Seek Head elements must also be updated to reflect to the Master elements’ new positions. If a file contained a Seek Head element at the start already and if that Seek Head was too small to contain the updated positions, the programs would end up in an endless loop trying to write data to the end, creating ever-growing files. This is now handled properly by voiding this too-small Seek Head & finding a proper space for a new one instead. Fixes #3338.
• MKVToolNix GUI: header editor: fixed pixelated icons on higher display scaling values. Fixes #3420.

Have fun 😁
