DragonFly BSD

Both dvd_info and bluray_info build out of the box once the dependencies re installed.

The default device for the optical drive is /dev/cd0

dvd_info

Install libdvdread and libdvdcss:

pkg install libdvdread libdvdcss

It not already installed, you will need automake and autoconf:

pkg install autoconf automake

Download the source code from github, and build:

autoreconf -fi
./configure
make

bluray_info

Install libbluray and libaacs:

pkg install libbluray and libaacs

Then check out the code as normal, and build:

autoreconf -fi
./configure
make

man 4 cd:

CDIOCRESET
CDIOCSETDEBUG
CDIOCCLRDEBUG Turn on (off) debugging for the appropriate device.

CDIOCSTART
CDIOCSTOP Tell the drive to spin-up (-down) the CD-ROM.

CDIOCALLOW
CDIOCPREVENT Tell the drive to allow (prevent) manual ejection of the CD-ROM disc.  Not all drives support this feature.

man 9 cd:

     CD_Q_NO_TOUCH    This flag tell the driver not to probe the drive at
