====== DragonFly BSD ======

  * [[https://www.dragonflybsd.org/~labthug/handbook/disks-naming.html|Device Names]]

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''

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

<code>
pkg install autoconf automake pkgconf
</code>

==== dvd_info ====

Install libdvdread and libdvdcss:

<code>
pkg install libdvdread libdvdcss
</code>


Download the source code from github, and build:

<code>
autoreconf -fi
./configure
make
</code>

==== bluray_info ====

Install libbluray and libaacs:

<code>
pkg install libbluray and libaacs
</code>

Then check out the code as normal, and build:

<code>
autoreconf -fi
./configure
make
</code>

==== research notes ====

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
                      attach time to see if there is a disk in the drive and
                      find out what size it is.  This flag is currently
                      unimplemented in the CAM cd driver.
