MKVToolnix

* Released v4.5.0.
* build: Building mkvtoolnix now requires libebml v1.2.0 and
libmatroska v1.1.0 or later.
* build: enhancement: mkvtoolnix now includes libebml and
libmatroska. The configure script will use them if either no
installed versions of them is found or if the installed version is
too old.
* mkvmerge: bug fix: Fixed an infinite loop when reading program
stream maps in MPEG program streams. Part of a fix for bug 589.
* mkvinfo: new feature: Added an option "--track-info" (short:
"-t") that displays one-line statistics about each track at the
end of the output. The statistics include the track's total size,
duration, approximate bitrate and number of packets/frames.
* mkvinfo: bug fix: The hexdump mode was accessing invalid memory
if the data to dump was shorter than 16 bytes. It was also
outputting the values as characters instead of hexadecimal
numbers. Patch by [email protected]. Fix for bug 591.
* mmg: enhancement: The output file name extension is
automatically set to ".mk3d" if the stereo mode parameter for any
video track is changed to anything else than "mono" or the default
value.
* mmg: enhancement: Added ".mk3d" to the list of known file name
extensions for Matroska files.
* mkvmerge, mmg: enhancement: Updated the "stereo mode" parameter
to match the current Matroska specifications.
* mkvmerge: enhancement: If mkvmerge encounters invalid UTF-8
strings in certain files or command line arguments then those
strings will simply be cut short. Before mkvmerge was exiting with
an error ("Invalid UTF-8 sequence encountered").
* all: new feature: Added online update checks. The command line
tools know a new parameter "--check-for-updates". mmg has a new
menu entry ("Help" -> "Check for updates") and checks
automatically when it starts, but at most once in 24 hours. Can be
turned off in the preferences. This function requires libcurl and
is not built if libcurl is not available.
* mkvmerge: bug fix: Avoid a crash due to invalid memory access if
a source file name contains numbers (happens only if mkvtoolnix is
built with MS Visual Studio). Fix for bug 585.
* mkvmerge: new feature: Added support for reading VP8 video from
Ogg files. Implements bug 584.
* mkvextract: enhancement: mkvextract will exit with an error if
the user specifies track IDs that do not exist in the source
file. This works in the "tracks" and "timecodes_v2" extraction
modes. Fix for bug 583.
* docs: mkvextract's man page has been updated to match the
program's expected command line syntax for the "timecodes_v2"
mode. Fix for bug 583.
* build system: Fixed building the Qt version of mkvinfo's
GUI. Fix for bug 576.
* mkvmerge, mmg: bug fix: Option files could not contain options
that started with '#' as they were interpreted as comment lines.
* mkvmerge: new feature: The "default duration" header field is
set for DTS audio tracks.
* build system: mmg's guide and its images are installed into the
location given by configure's "docdir" variable. Patch by Cristian
Morales Vega (see AUTHORS).
* all: Made the French translation selectable in all programs.
* mmg: bug fix: On Mac OS X the application type is set to a
foreground application preventing issues like the GUI never
getting focus.
