Software Update: MKVToolNix 6.8.0

Version 6.8.0 of MKVToolNix has been released. MKVToolNix is ​​a collection of open source programs that allow viewing, editing, and conversion of Matroska files. For example, sound tracks and subtitles can be added, removed or set as default. They are separate command line tools, but a graphical user interface is included. Versions are available for download for Windows, many Linux distributions, and OS X. This release includes the following changes and improvements:

• mkvmerge, mkvextract: new feature: added support for h.265/HEVC by merging the patches from DivX/Rovi Corp. So far HEVC is only supported as elementary streams and read from other Matroska files.
• mkvmerge: enhancement: The deprecated ISO 639-1 code “iw” is now recognized for Hebrew.
• mkvmerge: bug fix: The AC3 packetizer will re-derive the sampling frequency and the number of channels from the bitstream. This way obviously invalid information from the source container like a sampling frequency of 0 Hz will be fixed.
• mkvmerge: enhancements: AVI reader: audio chunks with obvious wrong size information (bigger than 10 MB) will be skipped.
• mkvmerge: bug fix: When reading M2TS files belonging to an MPLS playlist mkvmerge will now only copy packets whose timestamps lie between the “in time” and “out time” restrictions from the playlist’s entry corresponding to that M2TS file. Fixes #985.
• all: Windows 64bit: fixed return value checks for opening files. Fixes #972.
• all: Windows: when redirecting the program’s output with cmd.exe (eg “mkvinfo file.mkv > info.txt”) the programs will no longer write two line feed characters (r) per carriage return character (n). Fixes #970.
• all: Windows: the default charset for the files created with “–redirect-output” has been changed from the system’s local charset to UTF-8. Just like before it can be changed with “–output-charset”. See #970.
• all: bug fix: Windows: messages written to the console (cmd.exe) are not re-encoded to the local charset and back to UTF-16 before they’re handed over to ConsoleWriteW(). This fixes outputting Unicode characters to the console that are not part of the local charset. Fixes #971.
• extract: bug fix: using names of non-existing files in “attachments”, “chapters”, “cuesheet” or “tags” mode caused mkvextract to crash instead of emitting a proper error message. Fixes #964.
• mmg: bug fix: fixed the check for WebM-compatible track types for Opus.
• mkvmerge: bug fix: fixed muxing Sorenson v3 (SVQ3) video from QuickTime files.
• mkvmerge, mkvextract, mkvpropedit: enhancement: attachments in Matroska files with a missing FileUID element are not ignored anymore even though they violate the specs. mkvmerge generates a new FileUID instead.
• mkvmerge: re-built with the 64bit build for Windows with a newer compiler version in order to fix #957. It was due to a bug in gcc: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56742
• mmg: bug fix: mkvmerge’s file identification is written to a temporary file with –redirect-output and from there into mmg instead of directly from mkvmerge. This prevents from character re-coding done by wxWidgets 3.0.0 on Windows. Fixes #959.
• installer: enhancement: the architecture (32bit vs 64bit) is mentioned in the interface.
• installer: bug fix: the installation directory for 64bit builds will default to the proper directory (“C:Program Files” instead of “C:Program Files (x86)”). Fixes #956.
