/**
 * The basics of DVD encoding.
 * <p>
 * This example is very unsophisticated, there is a minimal progress indicator, but it does show
 * working DVD encoding.
 * <p>
 * Note that you must use a DVD that has no encryption, or you must have the appropriate DVD
 * decoding libraries installed.
 * <p>
 * Specify three things on the command-line:
 * <pre>
 *   [dvd-device] [output-file] [preset]
 * </pre>
 * For example:
 * <pre>
 *   simpledvd:///dev/dvd /home/rip.webm WEBM_LOW
 * </pre>
 * It is recommended to try the WEBM_LOW preset first.
 * <p>
 * Encoding a full DVD is going to be slow.
 * <p>
 * In principle, a start-time and end-time could also be set via media options - e.g. to trim
 * out unnecessary intro or trailing credits from the movie.
