Building a TV Server on a Synology NAS

1. Work Environment

NAS: Synology DS213 with DSM 4.2-â€3211
OS for Cross Compiling: CentOS 6.3

Before you begin:

Enable SSH.

If you have a battery backup unit then enable UPS.

Enable guest account.

Enable Web Station (for channel icons).

Create Windows Share folders (temp, recordings, documents, pictures, music, & videos)

You will need to donate $20 to mc2xml.dyndns.org to get a version of the software that will run on your Synology DS213 which has an Arm processor and won’t run the standard x86 version that you can download from the site.

You will also need a subscription to Schedules Direct.

2. Bootstrap

	DiskStation> cd /volume1/@tmp

	DiskStation> wget http://wizjos.endofinternet.net/synology/archief/syno-mvkw-bootstrap_1.2-7_arm-ds111.xsh

	DiskStation> chmod +x syno-mvkw-bootstrap_1.2-7_arm-ds111.xsh

	DiskStation> sh syno-mvkw-bootstrap_1.2-7_arm-ds111.xsh

	#-- needed since DSM 4.0

	DiskStation> vi /root/.profile

	#-- add /opt/bin:/opt/sbin: after PATH=

	#-- PATH=/opt/bin:/opt/sbin:/sbin:/bin:/usr/sbin:/usr/bin:/usr/syno/...

	#-- add this line at the end: export LD_LIBRARY_PATH="/opt/lib/:/lib/:$LD_LIBRARY_PATH"

	DiskStation> reboot

2.1 Dependencies for Compiling

	DiskStation> ipkg update

	DiskStation> ipkg upgrade

	DiskStation> ipkg install optware-devel

	DiskStation> ipkg install git

	DiskStation> ipkg install openssl

	DiskStation> ipkg install gcc

	DiskStation> ipkg install openssl-dev

	DiskStation> ipkg install nano

	#-- copy some libraries

	DiskStation> cp /opt/arm-none-linux-gnueabi/lib/libpthread-2.5.so /opt/arm-none-linux-gnueabi/lib/libpthread-2.5.so.bk

	DiskStation> cp /lib/libpthread.so.0 /opt/arm-none-linux-gnueabi/lib/libpthread-2.5.so

	DiskStation> cp /opt/lib/libssl.so.0.9.8 /opt/arm-none-linux-gnueabi/lib

	DiskStation> cp /opt/lib/libssl.so.0.9.8 /lib

	DiskStation> cp /opt/lib/libcrypto.so.0.9.8 /lib

3. Update GCC

Versions of TVHeadend above 3.2 require GCC 4.3+, therefore, it is necessary to update GCC in order to use the latest version of TVHeadend. This can take half a day to compile. Another option is to create a chroot environment.

	#-- If /bin/bash doesn't exist then create a symlink to it.

	DiskStation> ln -s /opt/bin/bash /bin/bash

	# Create a build directory and change to it

	DiskStation> mkdir /volume1/src

	DiskStation> ln -s /volume1/src /src

	DiskStation> cd /src

	DiskStation> make

	DiskStation> ipkg -force-depends remove gcc

	DiskStation> make install

	DiskStation> cd /opt

	DiskStation> wget http://download.silicondust.com/hdhomerun/libhdhomerun_20120405.tgz

	DiskStation> tar -xpf libhdhomerun_20120405.tgz

	DiskStation> cd /opt/libhdhomerun

	DiskStation> make

5. DVB Drivers

The following steps will build kernel modules for your Synology NAS. You can save time by downloading the files here.

5.1 Kernel Part (compiled with CentOS 6.3)

	#-- CentOS 6.3 needs the package ncurses-devel

	#-- 'make menuconfig' requires the ncurses libraries

	root@centos> yum install ncurses-devel

	root@centos> cd /home/administrator/Downloads

	#-- Synology Kernel Sources -- has to match with the cpu in your NAS

	root@centos> wget http://sourceforge.net/projects/dsgpl/files/Synology%20NAS%20GPL%20Source/2636branch/synogpl-2636-6281.tbz/download

	#-- DSM Tool Chain -- has to match with the cpu in your NAS

	root@centos> wget http://sourceforge.net/projects/dsgpl/files/DSM%204.1%20Tool%20Chains/Marvell%2088F628x%20Linux%202.6.32/gcc421_glibc25_88f6281-GPL.tgz/download

	#-- compile DVB Core Driver

	root@centos> cd /usr/local/arm-none-linux-gnueabi/source/linux-2.6.32/

	root@centos> cp /usr/local/arm-none-linux-gnueabi/source/linux-2.6.32/synoconfigs/88f6281 /usr/local/arm-none-linux-gnueabi/source/linux-2.6.32/.config

	root@centos> make ARCH=arm CROSS_COMPILE=/usr/local/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi- menuconfig

	#-- a menu appears, where you have to choose the device drivers for the tuners.

	#-- select "Device Drivers".

	#-- go to "Multimedia support", press Y to include

	#-- select "Multimedia support".

	#-- go to "Video For Linux", press M to include as module.

	#-- go to "DVB for Linux", press M to include as module.

	#-- select "Customize analog and hybrid tuner modules to build" and make sure that everything is selected in that section.

	#-- go back to "Multimedia Support" and select “Video Capture Adapters”.

	#-- go to “Conexant cx23416/cx23415 MPEG encoder/decoder support”, press M to include as module.

	#-- select “V4L USB devices” and place an M next to “USB Video Class (UVC)”, “Hauppage WinTV-PVR USB2 support”, and "Conexant cx231xx USB video capture support".

	#-- go back to main screen and exit (yes to save the new config).

	root@centos> make ARCH=arm CROSS_COMPILE=/usr/local/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi- prepare scripts

	root@centos> make ARCH=arm CROSS_COMPILE=/usr/local/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi- modules

	#-- compile DVB Drivers for HDHomeRun

	root@centos> cd /home/administrator/src

	root@centos> cvs -z3 -d:pserver:anonymous@dvbhdhomerun.cvs.sourceforge.net:/cvsroot/dvbhdhomerun co -P dvbhdhomerun

	root@centos> cd /home/administrator/src/dvbhdhomerun/kernel

	#-- edit the Makefile

	root@centos> nano Makefile

	#-- change KERNEL_VERSION

	#-- KERNEL_VERSION := 2.6.32.12

	#-- change KERNEL_DIR

	#-- KERNEL_DIR := /usr/local/arm-none-linux-gnueabi/source/linux-2.6.32

	root@centos> make ARCH=arm CROSS_COMPILE=/usr/local/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-

	#-- V4L modules are located at:

	#-- /usr/local/arm-none-linux-gnueabi/source/linux-2.6.32/drivers/media

	#-- (with the exception of the i2c files which are located in the i2c folder under drivers)
	
	#-- dvb-core.ko is located at:

	#-- dvb_hdhomerun_fe.ko

	#-- dvb_hdhomerun.ko are located at:

	#-- /home/administrator/src/dvbhdhomerun/kernel

	DiskStation> mkdir /opt/lib/modules

	DiskStation> mkdir /opt/lib/modules/2.6.32

	DiskStation> mkdir /opt/dvb_native

	DiskStation> mkdir /root/.xmltv

Copy all of the V4L KO files within the media folder (including the i2c folder under drivers) to /opt/lib/modules/2.6.32 of your NAS. Copy dvb-core.ko, dvb_hdhomerun_core.ko, dvb_hdhomerun_fe.ko, and dvb_hdhomerun.ko to /opt/dvb_native of your NAS. Copy the firmware files to /usr/syno/hotplug/firmware of your NAS.

5.2. Userspace Part

Copy the dvbhdhomerun folder from /home/administrator/src to /opt of your NAS.

	#-- edit the dvbhdhomerun config file

	DiskStation> nano /opt/dvbhdhomerun/etc/dvbhdhomerun

	#-- change the [XXXXYYYY-Z] to the serial #'s of your adapters.

	#-- [10343B98-0], [10343B98-1], [10368D88-0], & [10368D88-1]

	#-- change tuner_type=ATSC and save to /etc/dvbhdhomerun.

	#-- compiling userspace part requires cmake, not available through ipkg

	#-- CMAKE Sources

	DiskStation> cd /opt

	DiskStation> wget http://www.cmake.org/files/v2.8/cmake-2.8.8.tar.gz

	DiskStation> tar -xpf cmake-2.8.8.tar.gz

	DiskStation> cd /opt/cmake-2.8.8

	DiskStation> ./bootstrap

	DiskStation> make

	DiskStation> make install

	#-- compile userspace part

	DiskStation> cd /opt/dvbhdhomerun/userhdhomerun

	#-- edit CMakeLists.txt

	DiskStation> nano CMakeLists.txt

	#-- change LIBHDHOMERUN_PATH to where the

	#-- compiled SiliconDust driver/tools are

	#-- SET(LIBHDHOMERUN_PATH /opt/libhdhomerun)

	DiskStation> make
