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.
Version 33.0.0 "A Little Bit of Madness" 2019-04-12
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: 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.
Version 32.0.0 "Astral Progressions" 2019-03-12
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.
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).
