* Compilation
* Testing
If you try to compile the bindings from a development tree, you will
have to specify the path for VLC modules, which cannot be guessed by
the extension module.
For vlc.MediaControl:
mc=vlc.MediaControl('--plugin-path /path/to/vlc/directory'.split())
For vlc.Instance:
i=vlc.Instance('--plugin-path /path/to/vlc/directory'.split())
* Skeleton generation :
** For method bindings:
perl -n -e 'print "static PyObject *\nvlcInput_$2( PyObject *self, PyObject *args )\n{\n libvlc_exception_t ex;\n LIBVLC_TRY;\n $1_$2( self->p_input, &ex); LIBVLC_EXCEPT;\n Py_INCREF( Py_None );\n return Py_None;\n}\n\n" if /(libvlc_input)_(\w+)/ and ($2 ne "t")' ../../include/vlc/libvlc.h
** For method table:
perl -n -e 'print " { \"$2\", $1_$2, METH_VARARGS,\n \"$2()\" },\n" if /^(vlcInput)_(\w+)/' vlc_instance.c

This module provides a MediaControl object, which implements an API

the module provides a Object type, which gives a low-level access to
the vlc objects and their variables.
This module provides bindings for the native libvlc API of the VLC
video player. Documentation can be found on the VLC wiki :
