dvd_info

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 http://sourceforge.net/projects/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 toa ccess it (very useful for shell scripts that access DVD drives)

To download, see http://bluray.beandog.org/dvd_info/.

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, jansson

dvd_info

Usage: dvd_info [options] [-t track number] [dvd path]

By default will open /dev/dvd. Can also open directories or image files as well.

Examples:

dvd_info /dev/sr0
dvd_info EXCITING_MOVIE.iso
dvd_info ./

Human-friendly output

Here's what polling a Batman: The Animated Series DVD looks like:

$ dvd_info 1.005.0053.BATMAN_THE_ANIMATED_SERIES.iso

Specifing a track:

$ dvd_info -t 6 1.005.0053.BATMAN_THE_ANIMATED_SERIES.iso 
Disc Title: BATMAN_ANIMATED_SERIES_DISC1
Title: 06, Length: 00:22:20.100 Chapters: 01, Cells: 01, Audio streams: 04, Subpictures: 03

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.

$ dvd_info -j 1.005.0053.BATMAN_THE_ANIMATED_SERIES.iso
