Setting up Serviio on my Synology DS110J NAS

[patters]

OK, the DS111 has the Marvell Kirkwood ARM CPU:

Anyone know which java I should use? Is JamVM ok? Or should I use something else? Doesn't seem to be much info about this...

just had a quick look on a few other forums and they seem to think there is a version of sunJRE that will work on your NAS but at the moment i can not find were to source it from.


EDIT:

java 1.6 is availible on ' ipkg ' if you know what that is...

ffmpeg is also availible there

Finally got around to setting my DS111 up. Had to mess about making a DOS boot floppy (yes my machine is so old it has a floppy drive!) to use the WDIDLE3 utility to turn off the mental disk head parking on the Western Digital drives (it defaults to every 8 seconds - which is reckoned to kill the drive within a year!). It's almost silent now.
Really impressed with the management tool. Feels like an OS, but it's a web app. Now for the Java + Serviio part...

Would be great to one day see Serviio on here:
http://www.synology.com/enu/apps/3rd-party.php

Here are the instructions for getting ipkg (the package manager for embedded Linux systems) onto the system:
http://forum.synology.com/wiki/index.ph ... ,_ipkg_etc

[patters]

Ok, can someone who has this up and running please tell me which JVM they used? There's almost no info about this. JamVM is 1.5 only, and if I grep the list of packages available to ipkg for "java" or "vm" or "jvm" or "jre" I get nothing useful.

Are people using the Embedded JRE directly from Oracle here? http://www.oracle.com/technetwork/java/ ... 59989.html
I see here that the CPU in my unit is a Marvell Kirkwood mv6282 which according to the Marvell spec sheet is "fully ARMv5TE compliant".

Oh dear, the ffmpeg binary in the package repo is nearly three years old

SynologyDS111> ipkg list | grep ffmpeg
ffmpeg - 0.svn20080409-3 - FFmpeg is an audio/video conversion tool.

EDIT - ah, I see that there's already a recent ffmpeg binary built-in:

I got that Oracle Embedded JRE (ARMv5 build) from the link above installed. I used the readme notes from within the archive. I put it in /opt/java. Is that an appropriate location?
I then set the JAVAHOME environment variable

  Code:

export JAVAHOME=/opt/java/ejre1.6.0_21

and added the Java bin folder to the PATH environment variable:

  Code:

export PATH=$PATH:/opt/java/ejre1.6.0_21/bin


I then extracted the Serviio archive into /opt (it makes its own folder). From the Serviio folder I ran bin/serviio.sh. The disk made some encouraging noises. I force quit after a bit with ctrl-c and lo and behold I see a log folder, containing the following. Hooray! I'll continue tomorrow night...

That is looking good. The FFmpeg, though, may be built in 2010, but revision number 20k-something is quite old. Serviio currently bundles 26xxx revision build.

[patters]

Though I have occasionally played with Linux systems since 1999 when I first tried RedHat 5.0, dabbling with penetration testing distros, and having owned a hacked TiVo, and an NLSU2 NAS - literally the only thing I have ever managed to compile successfully was a 3dfx driver which wasn't distributed as a binary. Literally everything else I have ever tried fails to compile and when you ask on forums they always suggest making a ton of edits to the makefile. Since I'm not able to intuitively spot these, I'm not too confident about my chances of compiling a newer FFmpeg. Are you set up to potentially cross-compile one, or is that the sort of thing that has a minuscule success rate?

EDIT - This seems promising...

link look good to me patter give it a shot and go from there.

I don't even know what the free toolchain of choice is. Any suggestions?

Ok, did some more testing. I couldn't get the remote console working and I didn't want to start messing with host files so I decided to go for AcidumIrae's excellent PHP Web UI, since it's neater to be able to access the console from any device around the house, including iPhone

The real beauty on a Synology running DSM 3.0 is that it's already running PHP. All you need to do is go to Control Panel -> Web Services > Web Applications > Enable Web Station. This creates the folder /volume1/web. Use the root account to put the extracted Web UI files in say /volume1/web/serviio and browse to http://yourNASip/serviio and it just works - no configuration required at all. So simple!

I found that Serviio does occasionally throw errors to the console. I haven't investigated in detail (debug logging wasn't enabled) but here's the error:

I then tried playing a few clips on my Sony BDP and I discovered a fairly serious problem - the /tmp folder which Serviio defaults to using for transcoding seems to be on a partition with very limited space on these units. I couldn't log into my NAS at all (it tells you that it has run out of diskspace), but luckily I had an SSH session open so I was able to find /tmp/serviio and delete the offending file.
So on a Synology we need to configure the temp path in the transcoding tab of the console to use something like /volume1/@tmp which is stored on the main data partition.

Now how on earth to compile a newer FFmpeg... More clues here:
http://forum.synology.com/enu/viewtopic ... 37&t=21068

[patters]

Installing the developer tools (ipkg install optware-devel) will break the wget binary. It claims it clashes with wget-ssl or something. I then stupidly ran ipkg remove wget, which then prevents you from downloading any packages at all. Wget is still present, but it's linked to a missing library. Fortunately the solution is here:
http://forum.synology.com/enu/viewtopic ... 40&t=15087

Once you copy the wget binary from the Synology's software back into /opt/bin it's fine. Then you can re-run ipkg install optware-devel to get past the point where it failed.

Next we need to run ipkg install lame because the FFmpeg compile depends on this.

Then using a few examples I saw of compiling on ARM and looking at the options used for the Windows-compiled FFmpeg that Zip included with Serviio I ran this configure command in the folder of the source code I got from the Serviio downloads page.

  Code:

./configure --enable-static --disable-shared --disable-ffplay --disable-ffserver --enable-memalign-hack --enable-libmp3lame --arch=arm --enable-runtime-cpudetect --target-os=linux --enable-armv5te --disable-armv6 --disable-armv6t2 --disable-armvfp --disable-iwmmxt --disable-mmi --disable-neon

I ran make (slow with loads of warnings but no actual errors), then I ran make install. Seemed ok.

I've got it built but when I run ffmpeg from the command line it prefers the old one that's already in the path. Because I didn't supply a prefix in the configure options, the newly compiled one is in /usr/local/bin. If I go there and run ./ffmpeg I get this error:

  Code:

./ffmpeg: error while loading shared libraries: libbz2.so.1.0: cannot open shared object file: No such file or directory

I've read that I need to use the command ldd on the binary to list the dependencies but that's not installed, nor is it on ipkg.
The bzip2 ipkg package is installed, but that library is nowhere on my system.

EDIT - found and compiled libbz2 using the source here:
http://bzip.org/downloads.html
From the readme you'll see you need make -f Makefile-libbz2_so to build the library. I manually copied it over to /lib and made the symlink to the filename FFmpeg is looking for.

Now it wants libz.

EDIT 2 - Got that from http://www.zlib.net/
Run ./configure, then make. Don't bother installing it, it won't be detected. Manually copy the binary to /lib and create the symlinks to match what it made in the compilation folder.

And then... HOLY FRICKING COW! I DID IT!

congrats patters

maybe you could compile all the bits into 1 tutorial topic and we can make it stricky

Will do once I've tidied up all the loose ends. Now I need to get my head around where I should be installing these user-compiled binaries so they survive updates of the Synology DSM software (I think I should be using /opt/bin and /opt/lib). Also I need to figure what to put in init.rc to get Serviio running at bootup and so on.

It would be fantastic to get it all built into a Synology package, but I think there are several barriers to that. One possibly being that Serviio is not open source, and the other being that there are at least three different CPU architectures for these NASes (some are Freescale PPC, some are Marvell ARM, and others are Intel Atom), and different models of each so it may well just be better for people to compile. It's not hard though once someone like me has outlined all the steps (and stupid pitfalls). What I really find irritating are the people who post things like "please help me to install/compile this". Then they respond to their thread with "I fixed it" but with no information to help anyone else.

I've just tested it running and it seems to be able to transcode dts audio in hi-def mkv down to 2 channel ac3 in m2ts ok. 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 mkv to m2ts (copying streams) then the CPU stays at around 40% (because it's I/O-bound) then 5 mins into a film it falls away to pretty much idle - I guess it has finished remuxing.


Memory use even while running Serviio is around 20% at idle, 30% during a remux with audio transcode. 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 DS110J should run Serviio on their 128MB. They only have an 800MHz CPU though (Vs 1.6GHz on mine), so it would need testing by someone.

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

I have read up on the configure options for compiling FFmpeg and have refined the config, removing unnecessary disables, and sorting out the paths to use /opt:

  Code:

./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

It takes around 25 minutes to compile on the NAS.

For info - the CPU features of the Marvell Kirwood mv6282 are:

  Code:

Normally Serviio doen't require much memory but 385MB is recommended for when you index high def (ie 16 mpix) pictures - it loads it all into bitmap memory to resize for thumbnails.

Holy shit patters. If an ARM can do that then yes all Synology boxes should be able to. Been reading up on Atom D510 optimizations but it seems like won't have to if your ARM can take the heat. Nice work man.

if you write up a page like Zip said I'll get fired up and adapt it for my 1010+ with the Atom D510 in it.

Cheers,

Ok fellas. It's taken me the best part of the whole day to write up, and it's so complex that I've decided to make it a blog post on account of improved presentation options, and the hundreds of edits it took, but here it is:
http://pcloadletter.co.uk/2011/02/07/se ... h-arm-cpu/

It works beautifully! Well, it's clearly never going to manage realtime video transcoding, but it does audio transcoding and remuxing fine.

brilliant mate.

Just logged into my NAS after leaving it running Serviio all day and I see that the Resource Monitor clains 70% RAM is in use - the physical RAM is 256MB.
Running top gives this, which looks like Serviio is allocated 512MB of virtual memory:

I stopped and restarted Serviio using my daemon script and it's back to reporting around 30% memory used, but the top output looks similar:

CPU use is high (presumably it's checking for new content, which I have backed off to once every 2 hours to prevent the drive spinning up), but I have a much bigger library than when I was first testing (40GB of music and about 200GB of films). Is this a healthy expected situation - more of the DB being cached for instance - or could there be memory leak somewhere?
