 +====== MiniDLNA ======
 +MiniDLNA is a lightweight DLNA/UPnP media server. The MiniDNLA daemon serves media files (music, pictures, and video) to clients on a network. ​
  
 +
 +
 +==== Installation ====
 +<​code>​root@OpenWrt:​~#​ opkg update

 +<​code>​root@OpenWrt:​~#​ /​etc/​init.d/​minidlna enable

 +**Done!**
 +
 +miniDLNA server is ready to use :-D
 +
 +
 +==== Notes ====
 +  * MiniDLNA'​s inotify support may not work as expected when trying to watch on an overlayfs filesystem. In the case of extroot, e.g. you can watch on `/​overlay/​root/​minidlna` instead of `/​root/​minidlna`.

 +===== Chaos Calmer Tips =====
 +If you have a decent size music library, you will more than likely find building the minidlna database on your OpenWrt device extremely slow or impossible due to RAM constraints. The solution is to build the minidlna database on a Linux PC.
 +
 +  * Create a directory on your OpenWrt hard or flash drive to hold the minidlna log and database files.
 +     * ''​mkdir /​PathToHardDrive/​minidlna''​
 +  * On the OpenWrt device, modify the following ''/​etc/​config/​minidlna''​ lines to put the  minidlna database and log file on the hard or flash drive connected to your OpenWrt device.
 +     * <​code>​option db_dir '/​PathToHardDrive/​minidlna'​
 +option log_dir '/​PathToHardDrive/​minidlna'​
 +option inotify '​0'​
 +list media_dir '​A,/​PathToHardDrive/​PathToMp3s'</​code>​
 +  * Create a minidlna configuration file on the hard or flash drive connected to your OpenWrt device
 +     * Put the following in file ''​cp_minidlna_conf.sh''​.
 +         * <code bash>#​!/​bin/​sh
 +
 +. /​lib/​functions.sh

 +     * ''​./​cp_minidlna_conf.sh > /​PathToHardDrive/​minidlna/​minidlna.conf''​
 +  * Remove the hard or flash drive from the OpenWrt device and connect it to your Linux PC.
 +  * Build the minidlna database on a Linux PC with [[http://​sourceforge.net/​projects/​minidlna/​files/​minidlna/​1.1.4/​|minidlna 1.1.4]].
 +     * ''​minidlnad -d -R -v -f /​PathToHardDrive/​minidlna/​minidlna.conf''​
 +  * Remove the hard or flash drive from your Linux PC and reconnect to your OpenWrt device.
 +
 +| {{:​meta:​icons:​tango:​48px-dialog-warning.svg.png }} Ensure that the Linux PC portable hard or flash drive mount point is **exactly** the same as the OpenWrt hard or flash drive mount point. Otherwise, the OpenWrt minidlna will delete and rescan the database you generated on the PC since the paths don't match |
