    '''Create a media for an already open file descriptor.
    The file descriptor shall be open for reading (or reading and writing).
    Regular file descriptors, pipe read descriptors and character device
    descriptors (including TTYs) are supported on all platforms.
    Block device descriptors are supported where available.
    Directory descriptors are supported on systems that provide fdopendir().
    Sockets are supported on all platforms where they are file descriptors,
    i.e. all except Windows.
    @note: This library will B{not} automatically close the file descriptor
    under any circumstance. Nevertheless, a file descriptor can usually only be
    rendered once in a media player. To render it a second time, the file
    descriptor should probably be rewound to the beginning with lseek().
    See L{libvlc_media_release}.
    @param p_instance: the instance.
    @param fd: open file descriptor.
    @return: the newly created media or None on error.
    @version: LibVLC 1.1.5 and later.
