[Howto] Install DLNA media servers for Oleg firmware

[ecaddict]

After you've installed basic optware to the router using e.g. the Raas image directly or indirectly using my tutorial DLNA could be the next step.

A router with 128MB RAM (RT-N16, WL-500gP or WL-500W with RAM upgrade) is recommended if you plan to run many other programs as well.

If you don't know what DLNA is just check the Wiki.

The basic idea is that media servers (like the router) provide media to media player (like your TV, media player etc.) controlled by controller (like your PDA, mobile etc.)
There are many different options, the most popular being: mediatomb, minidlna and twonky.
You can install all, and disable what you don't like.

Original thread

Just copy-paste as such:

cd /opt/share/file; [ ! -f magic.old ] && mv magic magic.old
ipkg update; ipkg install readline mediatomb
mkdir -p /opt/etc/mediatomb
mkdir -p /usr/local/root/.mediatomb
flashfs save && flashfs commit && flashfs enable
sed -i 's/MT_USER="root"/MT_USER="admin"/' /opt/etc/mediatomb.conf
sed -i 's/MT_ENABLE=false/MT_ENABLE=true/' /opt/etc/default/mediatomb
cd /opt/share/mediatomb
cat sqlite3.sql | sqlite3 mediatomb.db
mv mediatomb.db /opt/etc/mediatomb/
/opt/etc/init.d/S90mediatomb start
/bin/ps | grep mediatomb

Original thread

If you prefer not to compile it, fetch my compiled version and extract it on the router. minidlna.tar.gz.

Copy-paste the following script and it will do everything (build also if you did not download the above binary version, however it can take half an hour in case of slow router):

Config adjustment in: /opt/twonkymedia/twonky-config/twonkymedia.ini
It has a rather slow web interface during media scan, but it works:
http://192.168.1.1:9000

It's possible to start and run all 3 at the same time, however most probably you don't need to and it can also use quite some memory and CPU time (even with powerful routers like the RT-N16 with 128MB RAM).
After tried what works for you, you can disable automatic start by renaming the /opt/etc/init.d/S90... script to DS90... (as only services starting with S... started). stop/start to the scripts work for manual stop/start.

Unfortunately I cannot answer which works for you as it depends on your player and your preferences.

Enjoy!
