# MKVToolNix v34.0.0 released

Here’s the May release of MKVToolNix, v34.0.0. It’s a tiny update with just three bugs fixed (and several translations updated).

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:

## Bug fixes

• mkvmerge: all subtitle frames are now treated as key frames in order to fix
wrong data in source files. Fixes #2541.
• mkvmerge: AV1: fixed frame timestamp calculation when reading bitstreams
that lack timing information from IVF files. Fixes #2553.
• mkvmerge: Matroska reader: fixed an infinite loop that could happen with
large video frames and applied timestamp files due to too much data being
buffered at the wrong time. Fixes #2550.

Have fun :)

# MKVToolNix v33.1.0 released

Well, I buggered up the handling of UNC paths on Windows in release 33.0.0. So… sorry? :) Here’s a fix for that. As this is just an emergency hot fix release I’ll include the news for v33.0.0, too.

There’ve been no changes regarding packaging since the previous release.

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:

# Version 33.1.0 “Primrose” 2019-04-15

## Bug fixes

• MKVToolNix GUI: multiplexer: Windows: using UNC paths
(e.g. \\server\Videos) when the option "automatically set the destination
file name" was set in the preferences, the GUI would create a destination
file name with forward slashes (e.g. //server/Videos/outputfile.mkv), a
syntax not supported by mkvmerge. Fixes #2533 & #2534.
• build system: the programs were accidentally built without stack protection
(-fstack-protector-strong) on recent versions of gcc and clang.

# Version 33.0.0 “A Little Bit of Madness” 2019-04-12

## Bug fixes

• mkvinfo: when using the --size option, mkvinfo will now report the
correctly if an element has an unknown size. Part of the fix of #2530.
• MKVToolNix GUI: info tool: clusters with an unknown size will now be read
and displayed correctly. Part of the fix of #2530.
• MKVToolNix GUI: multiplexer: Windows: trying to open Blu-ray index or
playlist files failed when the path to the files contained symbolic links
(e.g. when mounting a drive in a sub-folder via Windows’ disk management
utility). Fixes #2522.
• MKVToolNix GUI: multiplexer: if a destination file names ends with a number
in parenthesis (e.g. a year such as "(2017)"), that number will not be
stripped anymore during the process of ensuring the destination file name is
unique. Only those suffixes added automatically in prior attempts to make
the file name unique will be removed. Fixes #2521.
• MKVToolNix GUI: multiplexer: Windows: the GUI will let the user change the
drive letter part of the destination file name freely again and only verify
its validity right before starting to mux/adding to the job queue. Before it
tried to force that into something valid, often resulting in unintentional
paths (such as "C:\users\…\DC\files\…"). Fixes #2527.

Have fun :)

# MKVToolNix v33.0.0 relesaed

Another month, time for another release of MKVToolNix: v33.0.0. This is still a rather quiet time for MKVToolNix; hence this is another small bug fix release.

There’ve been no changes regarding packaging since the previous release.

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.

# MKVToolNix v32.0.0 released

Hey,

Here’s MKVToolNix v32.0.0, a really small bug fix release, the most important probably being the handling of Unicode code points > U+ffff (e.g. Emojis). For that to work a bug-fixed libEBML is also needed, which is why libEBML v1.3.7 is now required. It was released earlier today.

Other than that nothing has changed for package managers since v31.0.0.

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

• mkvinfo: when sizes are output the size of the element’s data portion is
output in addition to the element’s total size.
• MKVToolNix GUI: info tool: the element’s data portion is
shown as an extra column.
• MKVToolNix GUI: multiplexer: added column "Delay" to the track list
containing the additional delay to apply during multiplexing. Implements
#2506.

## Bug fixes

• all: fixed handling of Unicode code points > U+FFFF. Fixes #2516.
• mkvmerge: Windows: mkvmerge was crashing with an exception when trying to
identify certain files that can be used on Blu-rays (such as MPEG transport
streams of MPLS play list files) and when the file name was given as a UNC
path (e.g. \\servername\sharename\path\to\file.m2ts). The GUI emitted
errors such as "the JSON output could not be parsed" in that case. Fixes
#2507.
• MKVToolNix GUI: the portable mode wasn’t detected correctly when the current
working directory the GUI was started from wasn’t the directory the GUI’s
executable file was located it. Examples for when this is the case are
Windows’ "send to" or "open with" functions. Fixes #2501.
• MKVToolNix GUI: multiplexer: using button to change the current destination
directory to one of the recently used ones did not update the file name
according to the "make file name unique" setting. Part of the fix of #2519.
• MKVToolNix GUI: multiplexer: the function "set destination file name from
selected file’s name" will now only change the destination file’s name but
not its path. Part of the fix of #2519.

## Build system changes

• libEBML v1.3.7 and libMatroska 1.5.0 are now required as they fix their
handling of Unicode code points > U+FFFF (see #2516).

Have fun :)
