Installation is simple. First make sure that you have a recent version

of libmatroska installed on your computer. Refere to libmatroska's

|
|

|
|

Now run './configure'. If, for some reason, there is no 'configure'

script then run './autogen.sh' which will recreate it. If configure

|
||||||
can not find the Matroska libraries then you'll have to explicitely
|
|
||||||
state where they are, e.g.
|
|
||||||
|
|
||||||
./configure --with-matroska-include=/where/i/put/libmatroska/src \
|
|
||||||
--with-matroska-lib=/where/i/put/libmatroska/make/linux
|
|
||||||
|
|
||||||
After configure has finished simply run 'make' followed by 'make
|
|
||||||
install'. If you want a system wide installation then you'll have to
|
|
||||||
run 'make install' as root.

Installation
|
||||||
|
------------
|
||||||
|
|
||||||
|
Installation is not trivial but not impossible either. You first need
|
||||||
|
libebml and libmatroska, which can be obtained 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'.
|
||||||
|
|
||||||
|
After you've compiled the two libraries you can now compile MkvToolNix
|
||||||
|
itself:
|
||||||
|
|
||||||
|
bunzip2 < mkvtoolnix-...tar.bz2 | tar xvf -
|
||||||
|
cd mkvtoolnix-...
|
||||||
|
./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
|
||||||
|
make
|
||||||
|
|
||||||
|
And you're done.

If you're low on disk space then you can save a lot of space by

encoding the sound to MP3 with a very low bitrate. Using PCM is super

fast and uses a lot of space. MP3 is super small and takes rather

long. It's your choice. For MP3 use
