My own set of C programs that are small utilities for reading DVD info, and managing DVD drives.

Included:

  * ''dvd_info'' - a successor in spirit to [[lsdvd]], can output information about a DVD in human-readable or JSON output
  * ''dvd_drive_status'' - poll the DVD drive to see the status of a drive: open, polling, closed with no disc, closed with disc
  * ''dvd_eject'' - a small eject utility that does its best to make sure a drive is properly closed and ready to go before being able to access it (very useful for shell scripts that access DVD drives)
  * ''dvd_copy'' - copies a title straight to harddrive or stdout
  * ''dvd_player'' - a DVD player using [[mpv|libmpv]]
  * ''dvd_trip'' - a DVD ripper using [[mpv|libmpv]]
  * ''dvd_debug'' - a program to display an excessive amount of information about a DVD

The code is open-source, licensed under GNU GPL v2.

Source code is available at [[https://github.com/beandog/dvd_info]].

Build requirements: libdvdread, libdvdcss, libmpv (optional, needed for ''dvd_player'' and ''dvd_trip'')

=== Installation ====

Then you can do standard ''./configure; make; make install''

==== dvd_info ====

See ''--help'' for all the fancy stuff it can do. A man page (man dvd_info) is also included.

</code>

=== JSON output ===

The JSON output functionality will print *all* the information that ''dvd_info'' polls about the DVD. This is far more than the human-friendly output.
