Release notes

New features and enhancements - mkvmerge: AVC/H.264: the stereo mode is now set from the frame packing arrangement SEI message in the video stream if neither the command line nor the container specifies one. This works for MP4, Matroska, AVC elementary stream and MPEG transport stream input and is already known during file identification. Implements the AVC part of #6309. - mkvmerge: HEVC/H.265: the stereo mode is now set from the frame packing arrangement SEI message in the video stream if neither the command line nor the container specifies one. This works for MP4, Matroska, HEVC elementary stream and MPEG transport stream input and is already known during file identification. Implements the HEVC part of #6309. - MKVToolNix GUI: multiplexer: added new actions to the tracks context menu for enabling/disabling all items belonging to the same source file as the selected item. Implements #6318. Bug fixes - mkvmerge: MP4 reader: fixed losing video frames at the end of the file due to flushing the packetizers too early (when the first track ends instead of only when all tracks in the file have ended). Another byproduct is that BlockDuration attributes aren't set for the last frame when they aren't needed anymore. Fixes #6320. - MKVToolNix GUI: multiplexer: when identification fails due to an unrecognized or unsupported format, clicking the "Cancel" button in the error dialog shown no longer locks up the GUI in the state of "identification is still running", which disabled most…

Bug fixes - MKVToolNix GUI: executing actions, type "execute a program": all the variables (<MTX_…>) will now be replaced again in the argument list to the program to be executed. This was broken in v100. Fixes #6306. Security fixes - CVE-2026-90783: avilib: fixed potential heap overflows/invalid memory access in the ODML index handling due to unsiged integer multiplication wrapping around (colloquially known as "overflowing") with specifically crafted AVI files. Affects only mkvmerge as the other tools do not read AVIs. Reported by Tristan Madani [email protected].

Fixes #6299. - Windows: fixed converting the scalable SVG icons into the bitmap .ico ones used on Windows so that the grey background remains uniform & doesn't get garbled. Fixes #6280. Build system changes - The bundled libraries libEBML & libMatroska were updated to v1.4.7 & v1.7.2 respectively. Those versions fix various possible invalid memory accesses when reading data broken in certain, very specific ways, making them security sensitive. - libEBML v1.4.7 & libMatroska v1.7.2 are now required. - The meta info file org.bunkus.mkvtoolnix-gui.appdata.xml was renamed to org.bunkus.mkvtoolnix-gui.metainfo.xml.

Implemented by #6268. Fixes #6264. - MKVToolNix GUI: executing actions: Windows only: added a new type: executing a PowerShell script.

New features and enhancements - MKVToolNix GUI: the GUI will now remember the last used directory for selecting audio files for playback in "play audio file" program runners separately from any other "open file"-type situations. This directory will also default to /System/Library/Sounds on macOS now. Implemented by #6213. - MKVToolNix GUI: executing actions → running programs: added new variables: MTX_DESTINATION_FILE_BASE_NAME (the name without the drive letter, path or the suffix; e.b. /movies/A.new.hope.mkv → A.new.hope) and MTX_DESTINATION_FILE_SUFFIX (only the letters after the last ., e.g. /movies/A.new.hope.mkv → mkv). Added examples to all the destination file variables in the popup menu when adding variables in the preferences.

New features and enhancements - mkvmerge: FLAC reader: pictures embedded into the FLAC file were already handled as attachments, but they were left in the codec initialization data as well. They're now removed from the codec initialization data. See #6079. - mkvmerge: FLAC reader: padding metadata blocks will now be removed from the codec initialization data. See #6079. - mkvmerge: FLAC reader: embedded Vorbis comments will now be converted into Matroska comments or track/global header fields when available (e.g. TITLE will become the segment title & track's name, LANGUAGE will become the track's language). Copying of Vorbis comments that are converted into actual Matroska tags can be prevented with the usual options, e.g. --no-track-tags. The comments will also be removed from the codec initialization data.

Implements #3773. Bug fixes - mkvmerge: AAC parser: LOAS/LATM streams: fixed use of uninitialized data when the StreamMuxConfig element doesn't contain the audioMuxVersion element; version 0 must be assumed in such a case. The result was that sometimes certain valid AAC packets were dropped. Fix by Stefan Pöschel. - mkvmerge: HEVC/H.265 parser: fixed calculation of picture order count calculation that was triggered under rare circumstances. Fixes #3775. - mkvmerge: Matroska reader: enabled limits for how much data a single Matroksa reader instance might buffer when the muxing core looks for packets for specific tracks, avoiding huge memory consumption in cases where tracks have huge gaps between packets. This might happen when appending files containing forced-only subtitle tracks, for example. Fixes #3771. - mkvmerge: TrueHD reader: increased the probe range for TrueHD sync frames from 128 KB to 512 KB to avoid mis-detection with certain files with a lot of data between sync frames.

To escape it the @ sign has to be doubled as in --title @@midnight. Implements #3768. Bug fixes - mkvmerge, mkvpropedit, MKVToolNix GUI's multiplexer & header editor: the MIME type for TrueType & OpenType fonts will be set properly to either the current MIME types font/ttf & font/otf or to the legacy MIME types application/x-truetype-font & application/vnd.ms-opentype depending on whether the "use legacy font MIME types" option is disabled or enabled, even if the MIME database used by Qt returns the wrong one or even other MIME types such as application/x-font-ttf & application/x-font-otf. This was the case on Windows due to Qt 6.7.3 switching to a different embedded MIME database.
