# Libdv-1.0.0

## Introduction to Libdv

The Quasar DV Codec (libdv) is a software CODEC for DV video, the encoding format used by most digital camcorders. It can be used to copy videos from camcorders using a firewire (IEEE 1394) connection.

### Note

Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

### Libdv Dependencies

#### Optional

## Installation of Libdv

Install libdv by running the following commands:

    ./configure --prefix=/usr    \
                --disable-xv     \
                --disable-static &&
    make

This package does not come with a test suite.

Now, as the `root` user:

    make install &&
    install -v -m755 -d      /usr/share/doc/libdv-1.0.0 &&
    install -v -m644 README* /usr/share/doc/libdv-1.0.0

## Command Explanations

`--disable-xv`: This parameter is required if an X Window System is not installed. It also prevents configure testing for `libXv` which is only used for an obsolete program playdv that will not be built with current linux headers and would also need other obsolete dependencies.

`--disable-static`: This switch prevents installation of static versions of the libraries.
