Media Server Synology: The Ultimate Guide to Setup, Streaming & Best Practices (2025)

Unlock the full potential of your Synology NAS as a media server in 2025. This guide covers setup, streaming, advanced features, troubleshooting, and best practices for seamless home multimedia.

Introduction to Media Server Synology

Synology has built a solid reputation among IT professionals and home users as a leading provider of Network Attached Storage (NAS) solutions. As digital content continues to grow exponentially, organizing, accessing, and streaming multimedia files across multiple devices becomes increasingly important. A media server acts as a centralized library, allowing users to stream videos, music, and photos to compatible devices within a home network or remotely.
Leveraging Synology NAS as a media server brings numerous benefits in 2025. With robust hardware, the advanced DiskStation Manager (DSM) operating system, and a wide range of supported media protocols, Synology provides an efficient, secure, and user-friendly platform for multimedia management and streaming.

Understanding Synology Media Server

Synology Media Server is a dedicated package available through DSM's Package Center. Designed for multimedia enthusiasts, it utilizes DLNA (Digital Living Network Alliance) and UPnP (Universal Plug and Play) protocols, ensuring seamless device discovery and media streaming within your network. For developers interested in integrating real-time features, exploring a

Live Streaming API SDK

 can further enhance your media server's capabilities.

DLNA/UPnP Overview

DLNA and UPnP are essential for discovering and streaming media between devices without complex manual configuration. DLNA-certified devices, such as smart TVs, game consoles, and mobile devices, can instantly connect to your Synology NAS and access shared media libraries. If you're building custom streaming solutions, leveraging a

Video Calling API

 can enable interactive video experiences across your network.

Supported File Types and Formats

Synology Media Server supports a broad range of file formats, including:
  • Video: MKV, MP4, MOV, AVI, HEVC/H.265, H.264
  • Audio: MP3, AAC, FLAC, WAV
  • Images: JPEG, PNG, GIF, RAW
With the Advanced Media Extensions package, additional codecs like HEVC and AAC are supported, making the server compatible with modern multimedia standards. For those interested in mobile streaming, understanding

 integration can help optimize media delivery to Android devices.

Key Features

  • Media Indexing: Automatic cataloging of video, music, and photo libraries for quick access.
  • Transcoding: Real-time conversion of media files to formats compatible with client devices, reducing playback issues.
  • User Management: Granular control over who can access specific media folders.
  • Package Center Integration: Easy installation and updates through DSM. If you want to add audio interactivity, integrating a

    Voice SDK

     can enable live audio rooms for your users.
