MKVToolNix

VP8 video tracks can be read from Ogg files. Invalid UTF-8 strings no longer cause mkvmerge to abort. Several cases of invalid memory access were fixed. mkvinfo has a new "--track-info" feature. The "Default duration" header field is set for DTS tracks. mkvextract uses proper exit codes in case of errors. The documentation was updated.

Invalid memory handling in the MPEG ES reader was fixed. A French translation was added. Appending Matroska files with chapters will now cause the chapters to be merged into a single edition. A checkbox was added to mmg to disable extra compression for audio and video tracks by default. Several issues with the installation system were fixed. Incorrect usage of STL container classes was fixed.

SSA/ASS subtitle tracks were discarded even if selected for inclusion. The header editor and mkvpropedit sometimes crashed and created broken files. The job manager's "total remaining time" was totally wrong. A couple of malformatted translation entries were causing mmg to crash. Certain h.264 frame types were handled wrong. All of these problems have been fixed. mkvinfo displays the level and profile information for h.264 tracks. Attachments are written at the start of the file again. mkvextract will not continue after encountering an error anymore.

Various crashes in mkvmerge have been fixed. Splitting by size was basing the split decision on uninitialized variables causing multiple very small files to be created. DisplayWidth/DisplayHeight values that were only used to store the display aspect ratio are fixed to sensible values while providing the same aspect ratio information. mmg will remove entries from "recently used files" lists if they don't exist anymore.

A crash in mkvmerge regarding the header removal compression that occurred often in version 4.1.0 has been fixed. mmg no longer adds .mmg files opened by job execution to the file menu's list of recently accessed files.
