MKVToolNix 0.4.3 ================ These tools allow information about (mkvinfo) or extraction from (mkvdemux) or creation of (mkvmerge) or the splitting of (mkvsplit) Matroska files. Matroska is a new multimedia file format aiming to become THE new container format for the future. You can find more information about it and its underlying technology, the Extensible Binary Meta Language (EBML), at http://www.matroska.org/ At the moment only mkvinfo and mkvmerge are available, but the others will be as well. MkvToolNix aims to become for Matroska what the OGMTools are for OGM. The full documentation for each command is now maintained in its man page only. Type 'mkvmerge -h' to get you started. This code comes under the GPL (see www.gnu.org or the file COPYING). Modify as needed. The newest version can always be found at http://www.bunkus.org/videotools/mkvtoolnix/ Moritz Bunkus <moritz@bunkus.org> Installation ------------ Installation is not trivial but not impossible either. You first need libebml and libmatroska. If you run Debian/unstable on a x86 then you can get binary packages from my apt repository. Just add the following lines to /etc/apt/sources.lst: deb http://www.bunkus.org/debian/unstable/ ./ deb-src http://www.bunkus.org/debian/unstable/ ./ Run 'apt-get update' and 'apt-get install libebml-dev libmatroska-dev mkvtoolnix'. If you want to compile from source then get the two libraries via CVS: cvs -d:pserver:anonymous@cvs.corecodec.org:/cvsroot/matroska login Just hit the enter key if you're prompted for a password. Now check out the sources themselves: cvs -z3 -d:pserver:anonymous@cvs.corecodec.org:/cvsroot/matroska \ co libmatroska cvs -z3 -d:pserver:anonymous@cvs.corecodec.org:/cvsroot/matroska \ co libebml Change to libebml/make/linux and run 'make'. Change to libmatroska/make/linux. Once more run 'make'. As root run 'make install' in both directories. This will install the libraries into /usr/local/lib and the header files into /usr/local/include/ebml and /usr/local/include/matroska respectively. After you've compiled the two libraries you can now compile MkvToolNix itself. If you want to use the GUI for mkvinfo then you also need wxWindows v2.4.0 or later (http://www.wxwindows.org/). If configure finds the wx-config script then support for the GUI will be enabled. bunzip2 < mkvtoolnix-...tar.bz2 | tar xvf - cd mkvtoolnix-... ./configure make make install The last step must be run as root and is optional. If the configure script cannot find the EBML and Matroska headers, then you'll have to manually point it to their locations: ./configure --with-matroska-include=/where/i/put/libmatroska/src \ --with-matroska-lib=/where/i/put/libmatroska/make/linux \ --with-ebml-include=/where/i/put/libebml/src \ --with-ebml-lib=/where/i/put/libebml/make/linux Now run 'make' and 'make install'. Example ------- Here's a *very* brief example of how you could use mkvmerge with mencoder in order to rip a DVD: a) Extract the audio to PCM audio and let mencoder calculate the video frame numbers: mencoder -dvd 1 -ovc frameno -oac pcm -o frameno.avi If you're low on disk space and can invest a bit more time then you tell mencoder to encode to MP3 instead: mencoder -dvd 1 -ovc frameno -oac mp3lame -lameopts br=32 -o frameno.avi b) Extract the audio again, this time to a plain WAV file: mplayer -dvd 1 -vc dummy -vo null -hardframedrop -ao pcm -aofile audio.wav At the moment selecting a non-existant video codec with -vc results in the fastest audio dump. c) Normalize the sound (optional) normalize audio.wav d) Encode the audio to Vorbis: oggenc -q3 -oaudio-q3.ogg audio.wav e) Somehow calculate the bitrate for your video. Use something like... video_size = (target_size - audio-size) / 1.005 video_bitrate = video_size / length / 1024 * 8 target_size, audio_size in bytes length in seconds 1.005 is the overhead caused by putting the streams into an Matroska file (about 0.5%, that's correct ;)). video_bitrate will be in kbit/s f) Use the two-pass encoding for the video: mencoder -dvd 1 -oac copy -ovc lavc \ -lavcopts vcodec=mpeg4:vbitrate=1000:vhq:vqmin=2:vpass=1 \ -vop scale=....,crop=..... \ -o /dev/null mencoder -dvd 1 -oac copy -ovc lavc \ -lavcopts vcodec=mpeg4:vbitrate=1000:vhq:vqmin=2:vpass=2 \ -vop scale=....,crop=..... \ -o movie.avi g) Merge: mkvmerge -o movie.mkv -A movie.avi audio-q3.ogg -A is necessary in order to avoid copying the raw PCM (or MP3) audio as well.
