Media Server under Ubuntu

Using Freebox at home, I’m lucky to have a tool to display video, music,… directly on my TV screen.
I have disks storing such multimedia content on my FreeNAS.
I was looking for a server distributing it on my home network, and I came to pms-linux, now known as ps3mediaserver

Installation

One year ago, I manually installed everything necessary, but things have changed.
On my Ubuntu server (10.04), I just need to add a specific repository to get things installed:

sudo add-apt-repository ppa:happy-neko/ps3mediaserver
sudo apt-get update
sudo apt-get install ps3mediaserver


That’s all ! Nothing else to install…

Now, if you want to proceed manually, you will need to install:

  • mplayer
  • mencoder (with a special installation required on Lucid because of a bug)
  • ffmpeg
  • (optional) vlc
  • (optional) dcraw
  • (optional) tsmuxer
  • libmediainfo0 (specific repository: ppa:shiki/mediainfo)

Then you can install pms-linux:

sudo apt-get install pms-linux

Configuration

ps3mediaserver is provided with a nice User Interface.
You can start it by using command sudo ps3mediaserver

My Freebox is immediately detected as potential “renderer”, as well as my FreeNAS server (but not properly recognized: this is a non-issue, as I will never use it to display media !)

Using this interface, I personally modified the following parameters:

  • List of directories to manage (Navigation tab)
  • interface language (General Configuration tab)
  • transconding setup (Transcoding tab)

Note that this will create configuration file in ~root/.config/ps3mediaserver (files PMS.conf & WEB.conf)
But, when starting ps3mediaserver as a service (file /etc/init.d/ps3mediaserver), it looks for configuration file in /etc/ps3mediaserver

So, I decided to setup a small hack to solve this.
Once config files are created in root directory with GUI, I stopped it (button “Quit”), and I did this:

sudo -s
cd ~root/.config/ps3mediaserver
mv PMC.conf WEB.conf /etc/ps3mediaserver/.
ln -s /etc/ps3mediaserver/PMS.conf .
ln -s /etc/ps3mediaserver/WEB.conf .
exit

Note: in order to start when system is starting also, ps3mediaserver uses a start/stop script located in /etc/init.d/ps3mediaserver (which is normal behavior…).
But… this script relies on a configuration file (/etc/default/ps3mediaserver), which overwrites parameter PS3MS_START. Remember to set it to “1” if you want service to autostart…

Then, I customized this configuration file (PMS.conf) even further (that’s up to you):

  • I removed all sub-titles (parameter mencoder_audiosublangs)
  • I also removed thumbnails (parameter thumbnails)
  • I changed the default quality for transcoding (parameter mencoder_encode)
  • As my TV is not audio 5.1, I switched audio parameter back to “stereo” (parameter audiochannels)

Details of PMS.conf values are available here.
For your information, here is my PMS.conf file:

folders =/mnt/BT,/mnt/Multimedia,/mnt/Photos

thumbnails = false
thumbnail_seek_pos = 60
use_mplayer_for_video_thumbs = false

hide_enginenames = true
hide_transcode_folder = true
notranscode = m2ts,ts
audio_thumbnails_method = 0
forced_sub_tags =
forced_sub_lang = off
hide_extensions = true

I also wanted a special handling of some attributes for my Freebox.
So I went and modified file /etc/ps3mediaserver/FreeboxHD.conf

  • I forced not to transcode files that were created by Freebox itself (when recording a TV program and moving it to my multimedia disk): m2ts and ts extension files. This is done through parameter “StreamExtensions”
  • I removed automatic extension creation for transcoded files (parameter “UseSameExtension”)

For reference, here is my FreeboxHD.conf file:

RendererName=Freebox
RendererIcon=freebox.png
UserAgentSearch=fbxupnpav|libfbxhttp
Video=true
Audio=true
Image=true
SeekByTime=false

MaxVideoWidth=0

TranscodeAudioTo441kHz=true

Enjoy your multimedia server !
