I am running the stock kernel.  RTFM:

https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html


Check the kernel configuration:

toor at freebsd:/root # egrep 'option.+UDF' /usr/src/sys/i386/conf/GENERIC


It appears UDF is not included in the i386 GENERIC kernel.


While I should be able to figure out how to build a custom kernel, but 
these are archive discs and I would prefer a solution that works OOTB. 
Failing that, with minimum additional software/ effort.

I've been using packages:

toor at freebsd:/root # pkg search udfclient
udfclient-0.7.5_1              Tools for UDF filesystem

toor at freebsd:/root/freebsd.holgerdanske.com # pkg install udfclient
...

toor at freebsd:/root # /etc/periodic/weekly/310.locate
...

toor at freebsd:/root # makewhatis


RTFM -- nope:

toor at freebsd:/root # man udfclient
No manual entry for udfclient


Look for udfclient files:

toor at freebsd:/root # locate udfclient
/usr/local/bin/udfclient
/usr/ports/sysutils/udfclient
/usr/ports/sysutils/udfclient/Makefile
/usr/ports/sysutils/udfclient/distinfo
/usr/ports/sysutils/udfclient/files
/usr/ports/sysutils/udfclient/files/patch-uscsi_subr.c
/usr/ports/sysutils/udfclient/pkg-descr
/var/cache/pkg/udfclient-0.7.5_1-96e70f06e7.txz
/var/cache/pkg/udfclient-0.7.5_1.txz


Try online help -- not for noobs:

toor at freebsd:/root # udfclient --help
udfclient: illegal option -- -
Usage: udfclient [options] devicename [devicename]*)
-u level	UDF system verbose level
-r range	use only selected sessions like -3,5,7 or 6-
-W		allow writing (temporary flag)
-F		force mount writable when marked dirty (use with cause)
-b blocksize	use alternative sectorsize; use only on files/discs
-D		debug/verbose SCSI command errors
-s		byteswap read sectors (for PVRs)


STFW -- like an FTP client, eh?

WAG:

toor at freebsd:/root # umount /dev/cd0

Close Thunar.

Eject disc.  Insert disc.

toor at freebsd:/root # udfclient /dev/cd0
	bufcache thread initialising
Opening device /dev/cd0

UDF Dump of disc in device /dev/cd0
UDF sessions : No No

It appears udfclient can't see the DVD contents (?).
