  • Power supply for Raspberry Pi
  • Ethernet cable or WiFi dongle (for network connectivity)

Optionally, you can also connect an external hard drive or USB flash drive to store your media files to serve through MiniDLNA. The Raspberry Pi’s SD card may not have enough capacity to hold a large media library.

Install Necessary Software

With your Raspberry Pi hardware setup, you’ll need to install the MiniDLNA software package:

sudo apt update

sudo apt install minidlna

This installs all the components needed to run the MiniDLNA server.

Configure MiniDLNA

Before starting the MiniDLNA service for the first time, you’ll want to configure a few key options:

  1. Media Directories: In /etc/minidlna.conf, specify the directory paths where your media files are stored under media_dir=. Multiple directories can be listed separated by spaces.
  2. Friendly Name: Always customize the friendly name which will identify this server to client devices.
  3. Port Number: By default MiniDLNA uses port 8200. You can leave this as is unless you need to change due to a conflict.
  4. Other Settings: Review documentations for additional settings like network interface selection, transcoding options, album art, log levels etc.

Permissions and Dependencies

MiniDLNA functions best when:

  • The user account that runs the service has read access to mounted drives and media files
  • Support packages like ffmpeg are installed for optimal media transcoding

Set permissions accordingly and install optional packages like ffmpeg.

Start MiniDLNA Server

Once configuration is complete, start the MiniDLNA service:

sudo service minidlna start

The server will begin scanning media directories and publishing resources discoverable on your home network!

Mount External Drives

For serving a large media collection, mount external USB hard drives using the steps below:

  1. Format drive to ext4
  2. Create mount point: sudo mkdir /media/usbhd
  3. Get drive UUID: sudo blkid
  4. Add entry to fstab: UUID=XXXXXX /media/usbhd ext4 defaults 0 0
  5. Mount drive: sudo mount -a
  6. Set permissions for minidlna user to access drive
  7. Update media_dir paths in /etc/minidlna.conf

This will allow files on the external drive to be accessible through the MiniDLNA server as well alongside the SD card storage.

Streaming Media Experience

With everything set up adequately, you can now discover and stream files from the MiniDLNA server on devices that support the DLNA and UPnP standards. This includes many smart TVs, mobile devices, consoles and media players.

Some tips for optimal streaming:

  • Wired connection for the Raspberry Pi avoids WiFi bandwidth bottlenecks
