Serviio 1.9 package for Synology NAS

Serviio 1.6 in DSM Package Center

Running the Serviio DLNA server on a NAS is a very efficient solution. It allows all your media to be constantly available to all your devices, all without the need for a dedicated media PC. Most TV and Bluray players are already capable media renderers – so indexing the library, retrieving metadata, and streaming the content are where Serviio fits in. Device support is continually improved by a community of contributors, and this crowd-sourced aspect was what initially drew me to the project, leading me to create the Sony Bluray device profile back in 2010. Serviio can also connect to online sources of content such as catch-up TV portals and allow fuss free content playback without advertising, even on devices which lack native support. These online plugins are also community maintained.

This new version of the Synology package updates Serviio to version 1.9 which replaces the Flash Player dependency in Media Browser with an HTML5 player (release notes). Serviio 1.7 brought audio track selection preferences, and automatic subtitle downloading. The most significant enhancement from version 1.6 onwards is the new web management console which removes the need to install the separate Serviio Console application on a computer. The web console uses a modern adaptive design which works well on mobile devices, and it is now integrated with DSM so you will see its icon in the application menu when the package is running:

The package supports hardware transcoding on the DS214play and DS415play with Intel Evansport media processor. This support required substantial personal effort and was made possible by the very kind donation of a new DS214play unit from MrK/Boretom a fellow package maintainer for ASUStor devices.

 

Limitations

If you use a TV, Bluray or media player bought in the last few years it is likely to have very good format support. In this case even a low specification NAS will be adequate for streaming most video content. There are some limitations however, in particular with video transcoding.

Serviio’s MediaBrowser is a Pro version only feature, and is designed to allow direct playback of media on tablet devices without the need for dedicated apps. Please note that Apple iOS devices require video in H.264 and audio in stereo AAC format when streaming. With the exception of the Play models already mentioned, most Synology NAS models lack the CPU power to transcode video into H.264 in realtime. Even if the source video is already H.264, ARMv5 family CPUs (which lack an FPU) in the older models lack the power even to transcode AAC audio in realtime without libfdk_aac. Unfortunately I am unable to distribute an FFmpeg binary compiled against this library under the terms of its software license.

Ever since Serviio version 1.2 renderers that do not natively support subtitles via DLNA can have them burned into the video during transcoding, but as already explained a NAS usually lacks the CPU power to do this (more info on subs here). If you absolutely need hard subs for a particular film, you could start playback on your device then stop it and Serviio will continue transcoding. Then you will be able to try again in a few hours since it will play from the transcode cache folder. Newer TVs tend to support inline SRT subs, but for those with older models I can recommend the PlayStation 4 Media Player as a competent DLNA renderer with inline subs support.

I was able to compile FFmpeg for all seven supported architectures (ARMv5, ARMv7, ARM with NEON, Intel i686, Intel x64, Intel Evansport media processor, and PowerPC e500v2) with the additional libraries Serviio requires while using the libs included within DSM as far as possible. I have published my compilation methods to make the process easier for others in future since parts of it were difficult to figure out. Only the Intel CPU or higher end Annapurna Alpine ARM CPUs are likely to be of any practical use transcoding to H.264, since the other CPU types lack vector units (no AltiVec in QorIQ/PowerQUICC, and no NEON in Armada 370/XP).

 

Synology Package Installation

  • In Synology DSM’s Package Center, click Settings and add my package repository:
    Add Package Repository
  • The repository will push its certificate automatically to the NAS, which is used to validate package integrity. Set the Trust Level to Synology Inc. and trusted publishers:
    Trust Level
  • Serviio now requires Java 8 for OS-native filesystem watching, so you will need to install my Java SE Embedded package first if you have not already done so. Read the instructions on that page carefully too.
  • Now browse the Community section in Package Center to install Serviio:
    Community-packages
    Community packages are not listed in the All category for some reason. The repository only displays packages which are compatible with your specific model of NAS. If you don’t see Serviio in the list, then either your NAS model or your DSM version are not supported at this time. DSM 6.0 is the minimum supported version for this package.
  • When Serviio is started for the first time, a plugins folder will be created in the public shared folder (usually /volume1/public/serviio/plugins/). Download any Serviio online content plugins that you require and place the .groovy files in that location.
  • If you need subtitle support for glyphs not present in the default DejaVu fonts, add additional fonts to the following folder inside your NAS’s public shared folder (usually /volume1/public/serviio/fonts/).
 

Notes

  • You should reserve an IP address for your NAS (most home broadband routers will let you do this in the DHCP options), or use a static IP address. This will prevent Serviio from appearing multiple times in the menus of your renderer devices as its IP changes.
  • In the console disable ‘Generate thumbnails for local videos’ in the Metadata tab. Failure to do this can make adding videos to your library very slow on older NAS systems. With this disabled Serviio will still fetch thumbnail images automatically from the online databases.
  • Don’t alter the transcoded files location on the Transcoding tab, it’s already set to a sensible location for Synology systems. This particular folder is deleted each time your NAS restarts, and Serviio cleans up its temp files automatically in any case.
  • When adding folders to the media library use the Browse button. This will show the root of the entire NAS Linux filesystem, so you will find your DSM shared folders inside /volume1.
  • If you’re upgrading from a previous Serviio version you should check for updates of your online content plugins.
  • MediaBrowser (Pro only feature) can be opened using the link in the side bar of the web console (http://IPofYourNAS:23424/mediabrowser). If you want to use the MediaBrowser from a remote location you would need to either port forward 23424 on your router, or use SSH tunnelling. You can also manage Serviio remotely by SSH tunnelling port 23423 which the console uses. Both of these service definitions are added to the DSM Firewall.
  • Advanced users who wish to edit device profiles or enable debug logging can find the Serviio files in /var/packages/Serviio/target. You will need to use an SSH session to access this folder – it cannot be navigated to using DSM’s File Station. You will need to restart the Serviio package for profile changes to take effect.
  • Some users may wish to restrict running Serviio to specific times of day in order to free up RAM for a scheduled backup window for instance. This can be achieved by creating tasks to start and stop Serviio using the Task Scheduler in DSM Control Panel:
    Schedule service start
  • The package uses an FFmpeg wrapper script to modify the usual transcoding behaviour of Serviio to use the Intel Evansport hardware decoding and encoding available in the DS214play and DS415play models. I have left the FFmpeg wrapper scripts in the package even when not in use (in the Serviio/bin folder), because they are still useful for people trying to test a particular workaround or encoder setting. The wrapper was a tricky script to get working due to variable expansion precedence issues and quote handling. If you need it, just change the ffmpeg.location system property in /var/packages/Serviio/target/bin/serviio.sh to point to your modified wrapper script.
  • If additional fonts are not working as expected, some troubleshooting is available. You can re-create the fontconfig cache by connecting to the NAS via an SSH session as admin, and then running:
    sudo -i
    (enter admin password to become root)
    rm -rf ~/.fontconfig.cache
    FC_DEBUG=128 /var/packages/Serviio/target/bin/fc-cache --verbose
 

Hardware transcoding support

  • DS214play and DS415play with Intel Evansport SoC are the only models supported. Serviio uses the multimedia tool FFmpeg for manipulating media files, and I am only able to build a hardware-assisted FFmpeg for DS214play and DS215play. Subsequent to those products, Synology has marketed a number of other systems with hardware transcoding features but these are not supported by Serviio. The DS216play with STiH412 Monaco SoC uses a specialised build of Gstreamer for the Synology transcoding solution, so its hardware features cannot be used by FFmpeg. It seems likely that Synology is also using Gstreamer for the Intel Braswell or newer generation CPUs with QuikSync, since DSM ships with an older FFmpeg (2.7.1) than the version which introduced QuikSync support (2.8.0). To implement FFmpeg QuikSync hardware transcoding support requires Linux kernel patches for libmfx support which is not currently included in DSM 6.x, so Serviio support for Intel QuikSync on Synology is unlikely unless Synology in future switches to using FFmpeg for its own hardware transcoding solution.
  • FFmpeg will use hardware decoding where possible.
  • Although multiple hardware assisted decodes can take place simultaneously, only a single hardware encode is available. The package intelligently avoids race conditions for this.
  • Any FFmpeg commandline to encode using libx264 will automatically be sent to the hardware encoder when available.
  • profiles.xml has been modified so that the preferred transcode format for most devices for non-natively supported videos is H.264.
  • In order to add hardware H.264 encoding to a device profile, specify h264 as the desired codec and the FFmpeg wrapper script will make the necessary substitution automatically.
  • When the hardware encoder is used, the low quality settings in Serviio’s default libx264 options to favour encoding speed are ignored. The hardware encoder performance is not altered by quality settings.
  • If a media stream is being both hardware decoded and hardware encoded, it will use pipelined mode. Based on responses from Synology support during development this means that both jobs occur on the media processor without exposing the intermediate bitstream to FFmpeg. Consequently it is not possible to burn subtitles in pipelined mode. As a result my FFmpeg wrapper script will run the decode part of the job in software in order to do this. The unfortunate result is that the encoder cannot quite achieve real time transcoding during subtitle compositing. For full 1080p HD material it achieves around 20fps, whereas most movies are 24fps. This means that in order to watch a film with hard subs you would need to start it off, pause or stop the renderer and return a bit later to view. An alternative would be to mux the content into an MKV container with the desired subtitles before adding it to the Serviio library, assuming that your device supports SRTs in MKV.
  • The hardware encoded H.264 streams are not 100% compliant with the specification and fail validation using the tool DGAVCDec. For most tested renderers this does not affect playback (Bravia, Sony Bluray, iOS). However FlowPlayer (the Flash player in MediaBrowser) does not play these files satisfactorily and drops many frames resulting in jerky playback. Since the Evansport CPU is capable of realtime encoding regular Flash Video when the decode of the source file is hardware accelerated, MediaBrowser does not use hardware encoding for FlowPlayer. iOS and Android devices browsing content via MediaBrowser do benefit from hardware transcoding however.

Serviio 0.6 package for Synology NAS with Web UI

Serviio-package-with-webUI

The Serviio Web UI, styled to look like the regular DSM control panel widgets

 

UPDATE – This is no longer the most recent package. I have released a new version and created a new blog post to keep the comments on topic.

My guide for installing Petr Nejedly’s excellent Serviio 0.5.2 on Synology has been a very popular post, and many people have got it running. However, the process is still complex enough to deter a lot of people and, as I learned more about my Synology NAS, I realised that I could automate the whole thing. The biggest obstacle was creating a package for Java, but adding locale support to the syno Linux also proved difficult.

The PHP Web UI is now included which you can use to manage Serviio once it’s installed. I have tried to fix most of the localization issues with it, and have edited the CSS to give it the look and feel of DSM as much as I could. You could also use Serviio Remote Console from another computer if you prefer. Any online content plugins (ending in .groovy) that are found in your NAS ‘public’ share will also be installed into Serviio’s plugins folder automatically during installation.

The package will allow future upgrades while preserving the media database and the online plugins, as long as Serviio itself is ok with that. You can see Serviio’s log by clicking More in the Package Centre. DSM Package Center installs the application to /volume1/@appstore/Serviio though from what I understand, on multi-volume systems the user is prompted for a destination volume. If you need to edit device profiles, add online content plugins, or look at the log in detail that’s where you’ll find the files. Bear in mind that a NAS, even an Intel Atom powered one, is unlikely to have sufficient CPU power to manage realtime video transcoding (e.g. from DivX to MPEG2), though it will manage remuxing MKV to M2TS and realtime audio transcoding.

 

Download

If you have DSM 3.2, you can install directly from Package Center. In Settings -> Package Sources add my package repository URL which is http://packages.pcloadletter.co.uk

If you’re still on DSM 3.1, download one of the following packages. Right-click, Save As:

Serviio uses some open source libraries without which it would not have been possible.
By downloading the software on this page you are agreeing to the terms of the original Serviio End User Licence Agreement.
I accept no liability for any damage that may occur to your data or your cat’s health as a result of using this software :) The scripts are shown in full below, so you are free to assess any risks yourself.

 

Instructions

This package can be installed on an unmodified NAS – no hacking is required. It has been tested on DSM 3.1 and DSM 3.2. Here’s what you need to do:

  • In the DSM User control panel enable the User Home service
  • In the DSM Web Services control panel enable Web Station
  • Using the DSM Package Center install my Java SE for Embedded Synology package
  • Download any online content plugins that you require and leave the .groovy file for each in your NAS’s public shared folder
  • Determine your NAS’s CPU type, and install the appropriate Serviio Synology package from the download link above
  • Give it some time to start (click More Info in Package Center to see the Log tab – check it has loaded all the renderer profiles), then you can use the Serviio icon in the DSM drop down menu in the top-right to launch the Web UI. This Serviio icon will only be visible to admin users in DSM
  • To use the Serviio Remote Console from a Windows PC edit ServiioConsole.exe.vmoptions in the Serviio folder and add the line: -Dserviio.remoteHost=192.168.x.x (replace with your NAS’s IP address). It can take a minute or so to start – this is normal. For details on how to configure the Remote Console on other operating systems refer to the Serviio FAQ. It seems that the first time Serviio starts with a blank database the Remote Console will get stuck showing the message “Serviio is updating its Media Library”. If that happens wait a couple of minutes, stop and restart Serviio via the Package Center. Give it another couple of minutes then the remote console should work fine.
  • Once the console is up, disable ‘Generate thumbnails for local videos’, and set the ‘Transcoded files location’ to /volume1/@tmp. Don’t forget to use the Users control panel in DSM to grant permission for the Serviio user to read your files (if they’re not in the public share)
  • When you add folders to your library you need to use the ‘Add path…’ button (not ‘Add local…’) and give the full Linux path (e.g. /volume1/share-name/Movies). There are issues with the Add Local ajax file browser which mean that it doesn’t work properly even if you give PHP access to the filesystem root

Upgrading from 0.5.2

If you want to upgrade from a manually installed 0.5.2, you will need to follow the steps below. I was considering automating it, but it gets complicated trying to remove people’s edits from /etc/profile which may not be entirely consistent.

  • Stop the Serviio 0.5.2 daemon by running: /opt/etc/init.d/S99serviio.sh stop
  • Copy your media database somewhere safe: cp -R /opt/serviio/library/db /volume1/public
  • Follow the uninstallation steps at the bottom of my original guide
  • Install my Java Synology package
  • Install the Serviio Synology package from the download link above but don’t start it yet
  • Copy your saved database into position: cp -R /volume1/public/db /volume1/@appstore/Serviio/library (warning – for people with multiple volumes, the @appstore folder is not always on /volume1 apparently)
  • Force ownership on database files: chown -R serviio /volume1/@appstore/Serviio/library
  • Force ownership on transcode cache: chown -R serviio /volume1/@tmp/Serviio
  • Start Serviio in the DSM Package Center
  • Follow the rest of the settings guidelines from above

Serviio 0.6 DLNA server on Synology NAS

Serviio-Synology

Update – I have released a Synology package for Serviio 0.6

 

Serviio is an excellent free Java DLNA media server by Petr Nejedly which focuses on minimizing the amount of unnecessary media transcoding, and maximizing the use of renderer devices’ supported features. Version 0.6 adds support for streaming content from online RSS feeds. Since the installation process has changed a lot, I decided to create a new post rather than edit the old one. The guide is accurate for Synology DSM 3.2 beta, and the one tricky section with wget-ssl also applies for DSM 3.1. Older DSM versions may vary.

In the Synology DSM go to Control Panel > Terminal > enable SSH.

Read this Synology wiki document about modifying your NAS carefully and install the bootstrap for your model. If you have previously been messing around with your unit and want to set it back to defaults, you can run the bootstrap again. It will prompt you to delete a couple of folders and reboot, whereupon you can start afresh.

Download the PuTTY SSH client if you’re using Windows – other operating systems will already allow you to SSH from the terminal. Give the session a name, set the remote character set to UTF-8 as shown and save it before you connect (to save time in future). This will ensure that all characters display properly. The Mac OS SSH client defaults to UTF-8.
PuTTY remote character set configuration

Connect to your NAS’s IP address using SSH. Use the root account (same password as admin). For Mac OS for instance, use ssh root@x.x.x.x. I suggest enabling a more descriptive shell prompt which should reduce the chance of accidentally being in the wrong directory:

sed -i -r 's/(^PS1=.*$)/#\1\n\1/' ~/.profile
sed -i -e 's/^PS1=.*$/PS1=\"\\w\\\$ \"/g' ~/.profile
source ~/.profile
 

sed (stream editor) is a powerful tool which uses regular expressions. The first command opens the file ~./profile searches for the line beginning with PS1= and duplicates it, commenting out the first copy (so the change can be undone). Then second command sets the value PS1=”\w\$ “ which changes the prompt to be the current directory followed by dollar sign and space characters.

To install the development tools. Type:

ipkg update
ipkg install optware-devel
 

It will halt and complain that package wget-ssl clashes with wget. Continue with:

cp /opt/bin/wget /opt/bin/wget-old
ipkg remove wget
cp /opt/bin/wget-old /opt/bin/wget
ipkg install libidn
ipkg install optware-devel
 

This time it will finish successfully.

Next we need to install Lame MP3 encoder, providing libmp3lame which will be compiled into FFmpeg, and the Nano text editor (much easier to use than vi), and fix up some other issues (thanks to Nicolas Jolet for these):

ipkg install lame
ipkg install nano
#-----coreutils ls has no colour output by default
mv /opt/bin/ls /opt/bin/ls.bak
ln -sf /bin/ls /opt/bin/ls
#-----coreutils uptime is broken
mv /opt/bin/uptime /opt/bin/uptime.bak
ln -sf /usr/bin/uptime /opt/bin/uptime
 

Download Java SE for Embedded 7 from Oracle, selecting the Linux build for the appropriate CPU. The ARM v5 version is required for the Marvell Kirkwood CPU Synology Products. Note that there is a PowerPC e500v2 version – the CPU core in Synology products which use the Freescale mpc85x3). Unfortunately for PowerPC Synology owners, this depends on a higher version of glibc than the Synology DSM provides for this architecture. Until JamVM supports Java 1.6, or Synology update to glibc 2.4 you won’t be able to follow this guide on PowerPC models. This situation may have changed since DSM 3.2 beta was released.

You will need to sign up to receive the Java download link by email. It’s free to use for non-commercial evaluation use. Use your computer to save it into the top level shared folder of your NAS, which will probably be /volume1/public on the NAS filesystem. Then:

cd /volume1/public
mv ejre-7-fcs-b147-linux-arm-sflt-headless-27_jun_2011.tar.gz /volume1/@tmp
cd /volume1/@tmp
tar xvzf ejre-7-fcs-b147-linux-arm-sflt-headless-27_jun_2011.tar.gz
mv ejre1.7.0 /opt/local/java
 

Synology’s Linux build has no localization support built in, though it does use UTF-8 character encoding for the filesystem. That’s no problem for storage, however the Java VM inherits the locale setting of the host OS. Since this is undefined, Serviio and all other Java software will default to US-ASCII which is a big problem if you have filenames with non-US characters. The solution is to obtain the missing files to add locale support from the Synology toolchain, which is distributed under the GPL. Many thanks to IWarez at the Subsonic forum for this fix, though it took me a good while to realise the required files are indeed included in the ARM toolchain:

#-----for ARM CPU

mkdir /usr/lib/locale
localedef -c -f UTF-8 -i en_US en_US.utf8

 

Now use nano to edit some configuration files (Ctrl-o saves, and Ctrl-x exits).
First edit the profile for all bash shell users:

nano /opt/etc/profile
 

Make the changes shown in bold:

#
# Bash initialization script
#

PS1=”[\u@\h \W]$ ”
PATH=/opt/sbin:/opt/bin:/sbin:/bin:/usr/sbin:/usr/bin:/opt/local/java/bin
LD_LIBRARY_PATH=/opt/lib:${LD_LIBRARY_PATH}
JAVA_HOME=/opt/local/java
LANG=en_US.utf8

export PS1 PATH LD_LIBRARY_PATH JAVA_HOME LANG

 

Save and exit. Next edit the profile for all ash shell users (root):

nano /etc/profile
 

Add the changes shown in bold:

#/etc/profile: system-wide .profile file for ash.
PATH=”$PATH:/bin:/sbin:/usr/bin:/usr/sbin:/usr/syno/bin:/usr/syno/sbin:/usr/local/bin:/usr/local/sbin
PATH=”$PATH:/opt/local/java/bin”
JAVA_HOME=/opt/local/java
LANG=en_US.utf8
export JAVA_HOME LANG

umask 022

 

Save and exit. Now install Serviio 0.6:

cd /volume1/@tmp
wget http://download.serviio.org/releases/serviio-0.6-linux.tar.gz
tar xvzf serviio-0.6-linux.tar.gz
mv serviio-0.6 /opt/local/serviio
 

Next, compile librtmp which FFmpeg will use to retrieve Adobe Flash streaming video, the libssl static libraries (which librtmp depends on), libz and libbz2 static libraries for FFmpeg.

#-----libz static lib (ipkg only provides shared)
wget http://zlib.net/zlib-1.2.5.tar.gz
tar xvfz zlib-1.2.5.tar.gz
cd zlib-1.2.5
./configure --prefix=/opt --static
make
make install
 

At this point ou will see the error “cp: missing destination file operand after `/opt/lib'” because the libz.so shared library wasn’t compiled and the install script tries to copy it nonetheless. libz.a which we need was built ok, so ignore and continue.

cd ..

Notice that the ./configure command is line wrapped – it’s all one command. The make command takes approximately 25 minutes and will show many warnings during compilation, but this is expected.

Try running ffmpeg and check the compile time to make sure the newly compiled one is running. You should see this but with your compilation date and time:

In the DSM User Control Panel create a new user called serviio and set a password. Give that user access to the paths that contain the media you want to serve. Click the User Home button and enable the User Home Service. Go back to your SSH session and type:

nano /etc/passwd
 

Be very careful editing this file. A wrong move here could trash your system. Notice that the serviio user has a shell of /sbin/nologin. Change this to /bin/sh like the admin user has. Nano may try to line wrap this line as you type if you added an long account description. If it does, delete the carriage return before the line break and pull it back onto one line. Save and exit.

Now we’ll create the Serviio daemon start and stop script:

nano /volume1/@tmp/S99serviio.sh
 

Paste in the following text (mouseover and use the view source button to copy):

#!/bin/sh

User=serviio

case "$1" in

stop)
        echo "Stop Serviio..."
        su -l $User -c "/opt/local/serviio/bin/serviio.sh -stop" > /dev/null 2>&1 &
        ;;

start)
        # start Serviio in background mode
        su -l $User -c "/opt/local/serviio/bin/serviio.sh" > /dev/null 2>&1 &
        echo "Start Serviio..."
        ;;

restart)
        $0 stop
        sleep 1
        $0 start
        ;;
*)
        echo "usage: $0 { start | stop | restart}" >&2
        exit 1
        ;;

esac
 

Now make it executable and set the serviio user to be the owner of the Serviio folder (so it can create the media database, and log files):

chmod +x /volume1/@tmp/S99serviio.sh
chown -R serviio /opt/local/serviio
 

Test the script manually by running:

/volume1/@tmp/S99serviio.sh start
ps
 

The running process list should show the serviio user running the Serviio launcher shell script and the JVM like so:

Stop the daemon with:

/volume1/@tmp/S99serviio.sh stop
 

Check the web UI or the process list again and make sure it did indeed stop. If it’s all ok, we need to move the daemon launcher script so it starts automatically on boot (it will survive a DSM upgrade):

mv /volume1/@tmp/S99serviio.sh /opt/etc/init.d
 

Shutdown the NAS and restart, checking that Serviio starts by itself.

From now on you can start and stop Serviio manually using this same script (say if you were experimenting with changes to profiles.xml for instance):

/opt/etc/init.d/S99serviio.sh stop
/opt/etc/init.d/S99serviio.sh start
 

Remote console

AcidumIrae’s PHP Web UI is only for Serviio up to version 0.5.2 at present, and at the time of writing the Java Restful Web UI by kairoh does not yet integrate with Serviio 0.6. The only option for now is to use the proper Serviio Console from another computer. Since 0.6 there is no longer a requirement to change anything at the server end, so you just need to pass the parameter -Dserviio.remoteHost=x.x.x.x to the Serviio Console to indicate the IP of your Serviio server. This is covered in the Serviio FAQ. There’s quite a lag for it to start up (at least on Windows), but eventually you see the familiar icon.

 

Serviio settings

Navigate to the Transcoding tab. Set the transcoded files location to /volume1/@tmp. Failure to do this will result in temporary files being written to /tmp which will fill up the partition it’s on the moment you remux a 4GB movie, which would prevent you from logging into the NAS. If your Synology has an Intel CPU set the number of transcoding threads to 2. The dual cores should take advantage of FFmpeg’s pthreads support for a decent performance boost.

I recommend de-selecting Generate thumbnails for local videos in the Metadata tab. Note that you have to click Save on each tab or any change will not take effect. As you’ll see if you have a DLNA renderer that supports thumbnails, Serviio retrieves good ones from the online databases it checks so they’re not really needed. Often FFmpeg will get stuck trying to generate a thumbnail for a video and will lock the CPU at 100% for long periods of time. This issue was raised in this Serviio forum thread.

You can use the Library tab to add the media folders you want to share. Use Add Path not Add Local (we’re using a remote console remember) and express the paths in Linux syntax, e.g. /volume1/public/videos. Be sure that the serviio user has been granted read privileges over the folders you add (User Control Panel in DSM).

 

Performance

The Synology seems perfectly able to transcode DTS audio in a hi-def Matroska file down to 2 channel AC3 in MPEG-TS while copying the H.264 stream. The CPU use leaps up to 100% but I guess that’s because it’s running ahead transcoding down to the end of the file (and is CPU-bound).

If I play something that’s only remuxing the container and copying both audio and video streams then the CPU stays at around 40% (because it’s I/O-bound) then 5 minutes into a film it falls away to pretty much idle – I guess it has finished remuxing to the temporary file.

Memory use even while running Serviio is around 20% at idle, 30% during a remux with audio transcode, though I have noticed that with a larger library this creeps up to around 70%. I have a 2011 product so it has 256MB of RAM. This seems to indicate that the value line of products (with the j suffix) like the DS211j should run Serviio on their 128MB. They have a 1.2GHz CPU though versus 1.6GHz on mine (and the DS110j is only 800MHz), so it would need testing by someone.

All in all it would seem that the Synology products are very capable Serviio appliances!

 

Uninstalling

Log in as root and stop Serviio, then in the DSM User Control Panel delete the user called serviio. Undo the changes that you made to /opt/etc/profile and /etc/profile (the LANG, JAVA_HOME and java path modifications marked in bold earlier in the guide).

Finally, re-download the bootstrap for your model of NAS and run it again. It will tell you to delete a few folders and restart. This will completely trash all optware ipkg packages (i.e. everything in /opt) and undo everything else you did in this guide without affecting your data partitions. If you had any other ipkg packages installed since installing Serviio, these would also be lost.

Serviio 0.5.2 DLNA server on Synology NAS

last updated 24/08/2011 – fixed typos in locale section
Serviio-Synology

This guide is now redundant – I have released a Synology package for Serviio 0.6!

 

Serviio is an excellent free Java DLNA media server by Petr Nejedly which focuses on minimizing the amount of unnecessary media transcoding, and maximizing the use of renderer devices’ supported features. Some of the more main-stream servers like Windows Media Player just brute-force everything to MPEG2 video and MP3 audio, which degrades quality and wastes power. Though some servers like Mezzmo are better and will play Matroska files, even they tend to transcode all audio to AC-3 regardless of source type. As a Java app Serviio will run on anything that has a JVM, and the media tool it relies on is the open source and therefore highly portable FFmpeg. All these design priorities make Serviio an ideal choice to run on a NAS device since, when paired with a renderer with good format support like a Sony Bluray Player, the NAS will barely ever be transcoding.

I was about to buy a new large external hard disk, but once I realised that Serviio could probably run on a NAS I started looking at one of these instead. Synology seemed to offer a lot of value and seemed to have the sort of user-community enjoyed by my old Linksys NSLU2, which I promptly sold on eBay for almost what I had paid for it in 2007. I considered the value DS110j model but I decided to go for the more expensive DS111 on the basis that the double CPU speed and RAM would probably be a wise move.

This guide outlines how to get Serviio 0.5.2 running on the Marvell Kirkwood ARM CPUs found in most of the 2011 product line-up, but Synology devices also exist with Freescale PowerPC and Intel Atom processors. The key problem is finding a Java virtual machine, but FFmpeg also needs compiling from source. This is because although there is an FFmpeg binary bundled with DSM 3.0, it’s too old and lacks support for features critical to Serviio. This guide could be used for other CPU architectures, but the compilation options for FFmpeg need adapting.

In the Synology DSM go to Control Panel > Terminal > enable SSH.

Read this Synology wiki document about modifying your NAS carefully and install the bootstrap for your model.

Download the PuTTY SSH client.

Connect to your NAS’s IP address using SSH. Use the root account (same password as admin). I suggest that you perform the mod at the bottom of this post to enable colour directory listings and a more descriptive shell prompt which should reduce the chance of accidentally being in the wrong directory.

We need to install the development tools. Type:

ipkg install optware-devel
 

It will halt and complain that package wget-ssl clashes with wget. Continue with:

ipkg remove wget
cp /usr/syno/bin/wget /opt/bin
ipkg install wget-ssl
ipkg update
ipkg upgrade
ipkg install optware-devel
 

This time it will finish successfully.

Update – It seems that there is a serious problem with running ipkg on a clean install of DSM 3.1. This guide was written before it was released, and though I have since upgraded my Synology I haven’t encountered that issue, but there have been many comments about it. User mayk on the Synology forum seems to have the solution here. Use the extra wget verbosity switch to find out the exact package URL for the following two packages, then manually download them with wget and install:

cd /volume1/@tmp
ipkg install -verbose_wget libidn
wget url1
ipkg install -verbose_wget wget-ssl
wget url2
ipkg install filename1
ipkg install filename2
 

Next we need to install Lame MP3 encoder, providing libmp3lame which FFmpeg will be compiled to depend on, and the Nano text editor (much easier to use than vi):

ipkg install lame
ipkg install nano
 

JamVM is a JVM that gets mentioned a lot in connection with NAS systems, but it’s only Java 1.5, and Serviio needs version 1.6. Download the Java SE Embedded Runtime from Oracle, selecting the ARM v5 Linux version (note that there is a PowerPC e500v2 version – the CPU core in Synology products which use the Freescale mpc85x3). Unfortunately for PowerPC Synology owners, this depends on a higher version of glibc than the Synology DSM provides for this architecture. Until JamVM supports Java 1.6, or Synology update to glibc 2.4 you won’t be able to follow this guide on PowerPC models. This may have changed since DSM 3.1 was released.

You will need to sign up to receive the download link by email. It’s free to use for non-commercial self-educational use. Use your computer to save it into the top level shared folder of your NAS, which will probably be /volume1/public on the NAS filesystem. Then:

cd /volume1/public
mv ejre-1_6_0_21-fcs-b09-linux-arm-sflt-eabi-headless-27_sep_2010.tar.gz /volume1/@tmp
cd /volume1/@tmp
tar xvzf ejre-1_6_0_21-fcs-b09-linux-arm-sflt-eabi-headless-27_sep_2010.tar.gz
mkdir /opt/java
mv ejre1.6.0_21 /opt/java
 

Synology’s Linux build has no localisation support built in, though it does use UTF-8 character encoding for the filesystem. That’s no problem for storage, however the Java VM inherits the locale setting of the host OS. Since this is undefined Serviio, and all other Java software, will default to US-ASCII which is a big problem if you have filenames with non-US characters. The solution is to obtain the missing files to add locale support from the Synology toolchain, which is distributed under the GPL:

Now use nano to edit some configuration files (Ctrl-o saves, and Ctrl-x exits).
First edit the profile for all bash shell users:

nano /opt/etc/profile
 

Make the changes shown in bold:

#
# Bash initialization script
#

PS1=”[\u@\h \W]$ ”
PATH=/opt/sbin:/opt/bin:/sbin:/bin:/usr/sbin:/usr/bin:/opt/java/ejre1.6.0_21/bin
LD_LIBRARY_PATH=/opt/lib:${LD_LIBRARY_PATH}
JAVA_HOME=/opt/java/ejre1.6.0_21
LANG=en_US.utf8

export PS1 PATH LD_LIBRARY_PATH JAVA_HOME LANG

 

Save and exit. Next edit the profile for all ash shell users (root):

nano /etc/profile
 

At the last line make the changes in bold:

PATH=/opt/java/ejre1.6.0_21/bin:/opt/bin:/opt/sbin:$PATH
JAVA_HOME=/opt/java/ejre1.6.0_21
LANG=en_US.utf8
export JAVA_HOME LANG

 

Save and exit. Now install the Serviio application:

cd /volume1/@tmp
wget http://download.serviio.org/releases/serviio-0.5.2-linux.tar.gz
tar xvzf serviio-0.5.2-linux.tar.gz
mv serviio-0.5.2 /opt/serviio
 

In the DSM Control Panel got to Web Services > Web Applications tab > Enable Web Station.
Install AcidumIrae’s PHP web UI for Serviio. You will need to have enabled Web Station for the directory /volume1/web to exist.

wget http://labs.softjourn.com/attachments/download/67/serviio-0.5.2.1b.zip
unzip serviio-0.5.2.1b.zip
mv serviio-0.5.2 /volume1/web/serviio
 

You should already be able to browse to http://your_NAS_IP/serviio and see the user interface, though it will complain with a big red X that Serviio is not running.

FFmpeg depends on the libbz2 and zlib libraries, and although both are installed along with the optware-devel package, FFmpeg will only look for them in /lib rather than in their actual location in /opt/lib. Copies of the existing symbolic links will be fine:

cp /opt/lib/libbz2.so.1.0 /lib
cp /opt/lib/libz.so.1 /lib
 

Compile the patched version 26303 of FFmpeg from the Serviio download page. Running cat /proc/cpuinfo it is clear that the DS111 is an ARM 5TE platform so I enabled those specific optimizations:

cd /volume1/@tmp
wget http://download.serviio.org/opensource/ffmpeg-26303.tar.gz
tar xvzf ffmpeg-26303.tar.gz
cd ffmpeg
./configure --arch=arm --enable-armv5te --prefix=/opt --extra-cflags='-I/opt/include' --extra-ldflags='-L/opt/lib' --enable-static --disable-shared --disable-ffplay --disable-ffserver --enable-libmp3lame
make
 

Notice that the ./configure command is line wrapped – it’s all one command. The make command takes approximately 25 minutes on the 1.6GHz CPU and will show many warnings during compilation, but this is expected.

Update – Thanks to bakman for pointing out that for Intel Atom CPUs you will need to install the assembler YASM and also use the following ./configure parameters:

ipkg install yasm
./configure --arch=x86_64 --enable-ssse3 --prefix=/opt --extra-cflags='-I/opt/include' --extra-ldflags='-L/opt/lib' --enable-static --disable-shared --disable-ffplay --disable-ffserver --enable-libmp3lame
 

Another Update – Thanks to gregorio for parameters for Freescale PowerPC processors:

./configure --arch=powerpc --disable-altivec --prefix=/opt --extra-cflags='-I/opt/include' --extra-ldflags='-L/opt/lib' --enable-static --disable-shared --disable-ffplay --disable-ffserver --enable-libmp3lame
 

When the compile is done, install it.

make install
 

Try running ffmpeg and check the compile time to make sure the newly compiled one is running. You should see this but with your compilation date and time:

If you see the text below then something is wrong – this is the version included with DSM 3.0:

FFmpeg version SVN-r20167-snapshot, Copyright (c) 2000-2009 Fabrice Bellard, et al.

In the DSM User Control Panel create a new user called serviio and set a password. Give that user access to the paths that contain the media you want to serve. Click the User Home button and enable the User Home Service. Go back to your SSH session and type:

nano /etc/passwd
 

Be very careful editing this file. A wrong move here could trash your system. Notice that the serviio user has a shell of /sbin/nologin. Change this to /bin/sh like the admin user has. Nano may try to line wrap this line as you type if you added an long account description. If it does, delete the carriage return before the line break and pull it back onto one line. Save and exit.

Now we’ll create the Serviio daemon start and stop script:

nano /volume1/@tmp/S99serviio.sh
 

Paste in the following text (mouseover and use the icon in the top right to copy):

#!/bin/sh

User=serviio

case "$1" in

stop)
        echo "Stop Serviio..."
        su -l $User -c "/opt/serviio/bin/serviio.sh -stop" > /dev/null 2>&1 &
        ;;

start)
        # start Serviio in background mode
        su -l $User -c "/opt/serviio/bin/serviio.sh" > /dev/null 2>&1 &
        echo "Start Serviio..."

        #check libs FFmpeg depends on (in case DSM was upgraded)
        if [ ! -f /lib/libbz2.so.1.0 ]; then
                cp /opt/lib/libbz2.so.1.0 /lib
        fi
        if [ ! -f /lib/libz.so.1 ]; then
                cp /opt/lib/libz.so.1 /lib
        fi
        ;;

restart)
        $0 stop
        sleep 1
        $0 start
        ;;
*)
        echo "usage: $0 { start | stop | restart}" >&2
        exit 1
        ;;

esac
 

Now make it executable and set the serviio user to be the owner of the Serviio folder (so it can create the media database, and log files):

chmod +x /volume1/@tmp/S99serviio.sh
chown -R serviio /opt/serviio
 

Test the script manually by running:

/volume1/@tmp/S99serviio.sh start
ps
 

The running process list should show the serviio user running the Serviio launcher shell script and the JVM like so:

Stop the daemon with:

/volume1/@tmp/S99serviio.sh stop
 

Check the web UI or the process list again and make sure it did indeed stop. If it’s all ok, we need to move the daemon launcher script so it starts automatically on boot:

mv /volume1/@tmp/S99serviio.sh /opt/etc/init.d
 

Shutdown the NAS and restart.

Update – previously I had used the directory /usr/syno/etc/rc.d, but this is destroyed when the DSM software is updated. /usr/local/etc/rc.d is the official Synology location for 3rd party daemon init scripts but I found that it doesn’t work, so I used /opt/etc/init.d instead which also survives a DSM upgrade. I just tested this by upgrading to DSM 3.1-1605 and Serviio remained intact. I only had to copy the sym links for the libraries FFmpeg needs (“cp /opt/lib/libbz2.so.1.0 /lib” and “cp /opt/lib/libz.so.1 /lib”).

 

Web UI integration with the Synology DSM

I read the official Synology notes for 3rd party developers and decided to make some icons. The result is pretty neat:

Open an SSH session:

cd /usr/syno/synoman/webman/3rdparty
wget http://dl.dropbox.com/u/1188556/blog/serviio_syno_DSM.zip
unzip serviio_syno_DSM.zip
rm serviio_syno_DSM.zip
nano serviio/config
 

The file loaded into nano will look like this, and you need to edit the IP address to match the IP of your Synology (either put your syno on a static IP, or set a reservation in your broadband router’s DHCP server options).

{
 ".url": {
    "org.serviio.serviio": {
      "type": "legacy",
      "allUsers": true,
      "title": "Serviio",
      "desc": "DLNA Media Server",
      "icon": "images/icon_{0}.png",
      "url": "http://192.168.1.202/serviio/index.php"
    }
  }
}
 

I can’t find a way to avoid manually specifying the IP address like this – relative paths can’t be used because the Synology runs two different webservers: the DSM one on port 5000 without PHP, and the PHP-enabled Web Station one on port 80.

Log out of DSM and log back in. You will see the Serviio icon in the pull down menu in the top left, which you can drag to the desktop if you prefer:

 

Serviio settings

Navigate to the Transcoding tab. Set the transcoded files location to /volume1/@tmp. Failure to do this will result in temporary files being written to /tmp which will fill up the partition it’s on the moment you remux a 4GB movie, which would prevent you from logging into the NAS.

I recommend de-selecting Generate thumbnails for local videos in the Metadata tab. Note that you have to click Save on each tab or any change will not take effect. As you’ll see if you have a DLNA renderer that supports thumbnails, Serviio retrieves good ones from the online databases it checks so they’re not really needed. Often FFmpeg will get stuck trying to generate a thumbnail for a video and will lock the CPU at 100% for long periods of time. This issue was raised in this Serviio forum thread.

You can use the Library tab to add the media folders you want to share. Note that the Add Local… button will fail because the web service user does not have access to the root of the filesystem (probably a good thing security-wise). Use Add Path… instead and express the paths as I have done in the first screenshot above. Be sure that the serviio user has been granted read privileges over the folders you add (User Control Panel in DSM).

Update – If you really want to use the Ajax file browser UI, then go to DSM Control Panel > Web Services > PHP Settings tab > open_basedir and append /volume1: to the start of that list. Then on the Web Applications tab, disable Web Station, Ok, enable Web Station. Go back to your SSH session and run:

nano /volume1/web/serviio/afb/config.php
 

Change the value of $path from / to /volume1/public (or the top level shared folder where your media resides). You’ll notice however that when you use Add local button in the Serviio Library tab it’s very buggy. It will only list a maximum of 5 child folders from each node.

 

Performance

The Synology seems perfectly able to transcode DTS audio in a hi-def Matroska file down to 2 channel AC3 in MPEG-TS while copying the H.264 stream. The CPU use leaps up to 100% but I guess that’s because it’s running ahead transcoding down to the end of the file (and is CPU-bound).

If I play something that’s only remuxing the container and copying both audio and video streams then the CPU stays at around 40% (because it’s I/O-bound) then 5 minutes into a film it falls away to pretty much idle – I guess it has finished remuxing to the temporary file.

Memory use even while running Serviio is around 20% at idle, 30% during a remux with audio transcode, though I have noticed that with a larger library this creeps up to around 70%. I have a 2011 product so it has 256MB of RAM. This seems to indicate that the value line of products (with the j suffix) like the DS211j should run Serviio on their 128MB. They have a 1.2GHz CPU though versus 1.6GHz on mine (and the DS110j is only 800MHz), so it would need testing by someone.

All in all it would seem that the Synology products are very capable Serviio appliances!

 

Uninstalling

Log in as root and stop Serviio, then delete a couple of libraries which had been copied to /lib:

/opt/etc/init.d/S99serviio.sh stop
rm /lib/libbz2.so.1.0
rm /lib/libz.so.1
 

In the DSM User Control Panel delete the user called serviio. Undo the changes that you made to /opt/etc/profile and /etc/profile (the JAVA_HOME and java path modifications marked in bold earlier in the guide).

To remove the web UI, in DSM go to Web Services > Web Applications tab > Disable Web Station. Then:

rm -r /volume1/web/serviio
rm -r /usr/syno/synoman/webman/3rdparty/serviio
 

Finally, re-download the bootstrap for your model of NAS and run it again. It will tell you to delete a few folders and restart. This will completely trash all optware ipkg packages (i.e. everything in /opt) and undo everything else you did in this guide without affecting your data partitions. If you had any other ipkg packages installed since installing Serviio, these would also be lost.
