ReadyNAS CD/DVD support, abcde, handbrake etc

[HuwSy]

Hi

After many attempts with abcde and handbrake-cli with an external usb dvd rom drive I finally have it all working so I thought I would post here for anyone else needing.

This was on a Ready Nas 516 but I assume it would be similar for most with maybe some changes here and there.

First, to be able to install the tools I needed a repo for Jessie that actually loads so added the following to /etc/apt/sources.list

deb [trusted=yes] http://archive.debian.org/debian jessie main contrib non-free

Then installed abcde and it’s parts I was after, you may want more codecs etc

apt install abcde eject eyed3 id3 lame

Finally for abcde it needed updating newer than the repo version, I needed make below to install not any compiling

curl -kO https://abcde.einval.com/download/abcde-2.9.3.tar.gz | tar -xvf -
cd abcde-*
apt install make
make install

You may want to add these to the ~/.abcde.conf as the old server no longer exists I believe

CDDBMETHOD=cddb
CDDBURL="http://gnudb.gnudb.org/~cddb/cddb.cgi"

Now handbrake-cli took a bit more to get operational because the kernel drivers sr_mod.ko and cdrom.ko are missing.

First add to sources, well this is optional if you want libdvdcss2

deb http://download.videolan.org/pub/debian/stable/ /

Then ensure the key is added

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6BCA5E4DB84288D9

Now install the apps

apt install handbrake-cli libavcodec-extra libdvdcss2 udftools

Finally you will have to compile the drivers for sr_mod.ko and cdrom.ko as follows, do this on a share as it’s a few GB needed or on another machine to speed things up

This part must be done on the Nas, the .config file from this is needed later

apt install linux-image-extra
depmod -a
modprobe configs
zcat /proc/config.gz > .config
modprobe -r configs

Here on can be done on another Linux box or under wsl in windows if needed

wget https://www.downloads.netgear.com/files/GPL/ReadyNASOS_V6.10.8_WW_src.zip
unzip ReadyNASOS_*.zip
cd linux-4.4.157-x86_64
apt install libncurses-dev bc build-essential

Copy the config file into this linux kernel folder

make menuconfig

Navigate the menu
add device/block dev/packet writing (possibly not needed)
add device/scsi/scsi cdrom

make prepare
make modules_prepare
make # possibly not needed
make modules

Copy the files built as follows

cp drivers/cdrom/cdrom.ko /lib/modules/*/kernel/drivers/cdrom/
cp drivers/scsi/sr_mod.ko /lib/modules/*/kernel/drivers/scsi/

Finally bring them online

depmod -a
modprobe sr_mod
modprobe cdrom

Now enjoy dvds showing up as /dev/sr0 and being usable in handbrake or lsdvd etc

I would attach the compiled files for my 516 using 6.10.8 here if it let me but it only allows images it seems.

One thing missed. To keep these post reboot also add a file /etc/modules-load.d/cdrom.conf with content

sr_mod
cdrom

Thanks for sharing.  Can DVD .iso images also now be mounted?

This would make a great ReadyNAS add-on.  Unfortunately, ReadyNAS never put out a "ReadyNAS Apps for Dummies".  Their instructions are clearly intended for those that have previously created a .deb package, just not specifically for a ReadyNAS.

Hi

I would assume dvd iso only need udftools installed but it’s not as easy to test now I have it all setup.
