Introduction

Building a media server with Raspberry Pi allows you to create a custom, always‑on hub for movies, TV shows, music, and photos. A Pi 4 or Pi 5 consumes about the same power as an LED light bulb but can serve multiple 1080p streams (4 K direct‑play is possible if the client can handle it). With the right external storage and network setup, even large libraries feel snappy.

Affordability

A Pi 4 (4 GB) plus a quality microSD card costs far less than a low‑end mini‑PC or NAS enclosure—perfect for experimenting without a big upfront investment.

Flexibility

You can run Plex, Jellyfin, Emby, or lightweight DLNA servers, swap in RetroPie for gaming, or turn the same board into a NAS—often simultaneously.

Energy Efficiency

At idle, a Pi 4 draws roughly 3–4 W; under load it can hit 7–8 W, dramatically lower than an old desktop left on 24×7.

Limitations

• Hardware transcoding is limited; avoid real‑time 4 K → 1080p transcodes.
• USB‑attached drives work well, but Gigabit Ethernet tops out around 940 Mbps.
• SD cards wear out; use them only for the OS and keep media on USB SSDs or HDDs.

Hardware Requirements

Initial Setup Process

1. Flash Raspberry Pi OS Lite to the SD card with Raspberry Pi Imager.
2. Enable SSH (Imager → Settings → “Enable SSH”) so you can work headless.
3. Boot the Pi, connect via SSH (ssh pi@), and run:

   sudo apt update && sudo apt full-upgrade -y
   

4. Mount your media drive—add a line to /etc/fstab:

   UUID= /mnt/media ext4 defaults,nofail 0 2
   

5. Create folders movies, tv, music, and photos under /mnt/media.

Raspberry Pi Plex Server Setup

Choose Plex if you want polished Smart‑TV apps and easy remote streaming.

curl  | sudo apt-key add -
echo "deb  public main" | \
  sudo tee /etc/apt/sources.list.d/plexmediaserver.list
sudo apt update && sudo apt install plexmediaserver -y

1. Open http://:32400, run the setup wizard, and point libraries at /mnt/media.
2. Enable hardware acceleration (Settings → Transcoder → Use hardware acceleration when available).
3. For secure external access, place Plex behind a reverse proxy (Caddy, Nginx, or Cloudflare Tunnel).

Raspberry Pi Jellyfin Installation Guide

Choose Jellyfin for a fully open‑source stack — no paywalled features.

curl -fsSL  | bash -s
sudo apt install jellyfin -y

1. Visit http://:8096 and complete the setup wizard.
2. In Dashboard → Playback, enable VA API hardware decoding (Pi 4 64‑bit kernel).
3. Schedule library scans under Scheduled Tasks, and install extra plugins (Intro Skip, Theme Music) via Plugins → Catalog.
4. Use a reverse proxy or VPN for secure remote access.

Using Raspberry Pi as a Retro Gaming Console

sudo apt install git -y
git clone --depth=1 
cd RetroPie-Setup && sudo ./retropie_setup.sh

1. Select Basic install, then configure your controllers.
2. SFTP legally‑owned ROMs to /home/pi/RetroPie/roms/.
3. Reboot; EmulationStation will auto‑populate with systems that have ROMs.

Tip: A mild overclock to 2 GHz plus a fan helps demanding emulators (N64, PSP).

Streaming with Raspberry Pi

Local Casting

• Install rpiplay for AirPlay mirroring.
• Enable DLNA in Jellyfin for quick discovery on smart TVs.

Live Streaming (self‑hosted)

sudo apt install nginx
# Add an RTMP block in /etc/nginx/nginx.conf, then:
sudo systemctl restart nginx

Point OBS Studio on your desktop to rtmp:///live.

Raspberry Pi NAS Setup

1. Install OpenMediaVault 6:

   sudo apt install openmediavault -y
   

2. In the OMV web UI:
   • Mount your USB drive.
   • Create shared folders (movies, music, etc.).
   • Enable SMB/CIFS and assign permissions.
3. For snapshots/backups, enable rsync tasks or use Btrfs if supported by the drive.

Raspberry Pi Music Server Guide

Tips and Best Practices

• Backups: Use rsnapshot or borgbackup to an external drive.
• Thermals: Keep CPU < 70 °C with a small fan or passive heat‑sink case.
• UPS: A USB‑powered UPS HAT prevents SD‑card corruption on power loss.

Conclusion

A Raspberry Pi media server is budget‑friendly, power‑efficient, and endlessly hackable. Whether you lean on Plex’s polished ecosystem or Jellyfin’s open‑source freedom, bolt on RetroPie or NAS features as needed, and enjoy a custom entertainment hub that grows with you.

FAQ

1. Minimum hardware? Pi 3 B+ works, but Pi 4 (4 GB) or Pi 5 is smoother, plus a 16 GB microSD, USB SSD/HDD, and wired Ethernet.
2. 4 K support? Pi 4 can direct‑play 4 K HEVC; avoid real‑time transcodes.
3. Multiple servers? Plex and Jellyfin can coexist, but simultaneous transcoding will max the CPU.
4. Security tips? Update regularly, use strong passwords, and reverse‑proxy over HTTPS or VPN.
5. Remote access? Yes—Cloudflare Tunnel, WireGuard, or another VPN keeps it secure.
