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

root@OpenWrt:~# opkg update
root@OpenWrt:~# opkg install minidlna

Configuration

edit file: /etc/minidlna.conf or /etc/config/minidlna.conf or /tmp/minidlna.conf depend on your miniDLNA Version

#------------------------------------------------------#
# port for HTTP (descriptions, SOAP, media transfer) traffic
#------------------------------------------------------#
port=8200

#------------------------------------------------------#
# network interfaces to serve, comma delimited
#------------------------------------------------------#
network_interface=br-lan

#------------------------------------------------------#
# set this to the directory you want scanned.
# * if have multiple directories, you can have multiple media_dir= lines
# * if you want to restrict a media_dir to a specific content type, you
#   can prepend the type, followed by a comma, to the directory:
#   + "A" for audio  (eg. media_dir=A,/home/jmaggard/Music)
#   + "V" for video  (eg. media_dir=V,/home/jmaggard/Videos)

Execute Daemon

root@OpenWrt:~# /etc/init.d/minidlna enable
root@OpenWrt:~# /etc/init.d/minidlna start

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.
    • option db_dir '/PathToHardDrive/minidlna'
      option log_dir '/PathToHardDrive/minidlna'
      option inotify '0'
      list media_dir 'A,/PathToHardDrive/PathToMp3s'
  • 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.
      • #!/bin/sh
         
        . /lib/functions.sh
         
        minidlna_cfg_append() {
        	echo "$1" 
        }
         
        minidlna_cfg_addbool() {
        	local cfg="$1"
        	local key="$2"
        	local def="$3"
        	local val
         
        	config_get_bool val "$cfg" "$key" "$def"
        	[ "$val" -gt 0 ] && val="yes" || val="no"
        	minidlna_cfg_append "$key=$val"
        }
         
        minidlna_cfg_addstr() {
        	local cfg="$1"
        	local key="$2"
        	local def="$3"
        	local val
         
        	config_get val "$cfg" "$key" "$def"
        	[ -n "$val" ] && minidlna_cfg_append "$key=$val"
        }
         
        minidlna_cfg_add_media_dir() {
        	local val=$1
         
        	minidlna_cfg_append "media_dir=$val"
        }
         
        minidlna_create_config() {
        	local cfg=$1
        	local port
        	local interface
         
        	config_get port $cfg port
        	config_get interface $cfg interface
         
        	[ -z "$interface" -o -t "$port" ] && return 1
         
        	echo "# this file is generated automatically, don't edit" 
         
        	minidlna_cfg_append "port=$port"
        	minidlna_cfg_append "network_interface=$interface"
         
        	minidlna_cfg_addstr $cfg friendly_name
        	minidlna_cfg_addstr $cfg db_dir
        	minidlna_cfg_addstr $cfg log_dir
        	minidlna_cfg_addbool $cfg inotify '1'
        	minidlna_cfg_addbool $cfg enable_tivo '0'
        	minidlna_cfg_addbool $cfg strict_dlna '0'
        	minidlna_cfg_addstr $cfg album_art_names
        	minidlna_cfg_addstr $cfg presentation_url
        	minidlna_cfg_addstr $cfg notify_interval '900'
        	minidlna_cfg_addstr $cfg serial '12345678'
        	minidlna_cfg_addstr $cfg model_number '1'
        	minidlna_cfg_addstr $cfg minissdpsocket
        	minidlna_cfg_addstr $cfg root_container '.'
        	config_list_foreach "$cfg" "media_dir" minidlna_cfg_add_media_dir
         
        	return 0
        }
         
         
        config_load 'minidlna'
         
        minidlna_create_config config
    • chmod +x cp_minidlna_conf.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 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.
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

This method has been tested with an Openwrt device with 32MB of RAM and a music library of over 11,000 songs. You may also want to add swap if you are running low on memory.
