My own set of C programs that are small utilities for reading DVD info, and managing DVD drives.
Includes:
dvd_info - a successor in spirit to lsdvd, can output information about a DVD in human-readable or JSON outputdvd_drive_status - poll the DVD drive to see the status of a drive: open, polling, closed with no disc, closed with discdvd_copy - copies a title straight to harddrive or stdoutdvd_player - a DVD player using libmpvdvd_rip - a DVD ripper using libmpvdvd_backup - back up a DVD completely, similar to dvdbackup (note the different names)dvd_debug - a program to display an excessive amount of information about a DVDThe 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_rip)
Then you can do standard ./configure; make; make install
Run –help to see what it can do.
There is more documentation available on the project wiki. Also, there are man pages for each program.
