MPD (DASH) Online Player | Free MPEG-DASH Video Player for Adaptive Streaming

MPD (Media Presentation Description) is the XML-based manifest file format for MPEG-DASH (Dynamic Adaptive Streaming over HTTP), the international standard for adaptive bitrate streaming. Unlike HLS's M3U8 text-based playlists, MPD files use a structured XML format to describe:

• Available video/audio representations (resolutions, bitrates, codecs)
• Segment timing and duration information
• DRM protection information (ContentProtection elements)
• Adaptation sets for different audio languages, subtitles, and video qualities
• Multi-period content for live events with ad insertion

MPD files don't contain actual video data - they reference segmented media files (typically fMP4) hosted on a server. This structure allows for more flexible adaptation logic than HLS, supporting multiple codecs, container formats, and DRM systems in a single manifest.

Your privacy is our top priority:

• 100% Local Processing: All manifest parsing, stream decoding, and playback happens locally in your browser using dash.js - no data is sent to our servers
• No Logging: We do not log your IP address, MPD URLs, viewing activity, or any personal data
• No Tracking: No analytics cookies, pixel trackers, or user fingerprinting
• No Data Sharing: We never share any user information with third parties
• HTTPS Only: Our entire website uses TLS encryption for all communications
• DRM Privacy: DRM license requests go directly to the content provider's license server - we never intercept or log DRM-related data

Your DASH streams connect directly between your device and the video server - we act only as a playback interface with zero intermediation of your streaming data.

We use standard dash.js configurations aligned with official guidelines for optimal DASH playback:

const dashConfig = {
  streaming: {
    buffer: {
      bufferPruningInterval: 2,
      bufferToKeep: 10,
      maxBufferLength: 30,
      stableBufferTime: 4,
    },
    abr: {
      ABRStrategy: 'abrDynamic',
      initialBitrate: { video: 0 },
      bandwidthSafetyFactor: 0.75,
      minBitrate: { video: 0 },
    },
    lowLatency: {
      enabled: true,
      latencyThreshold: 2,
    },
    retry: {
      maxAttempts: 5,
      baseDelay: 1000,
    }
  },
  manifest: {
    defaultPresentationDelay: 0,
    ignoreMinBufferTime: true,
  }
};
                        

These settings balance fast startup times with playback stability, even for low-quality DASH streams and high-latency network conditions.

Here's a step-by-step troubleshooting guide for the most common issues:

1. MPD won't load
   • Verify URL is valid (test in browser first - should return XML)
   • Check for CORS errors (use our CORS proxy for remote manifests)
   • Ensure URL uses HTTPS (browsers block HTTP content on HTTPS sites)
   • Check MPD format (must be valid XML compliant with MPEG-DASH spec)
2. Buffering/Freezing
   • Reduce playback quality in player settings
   • Test internet speed
   • Disable VPN/proxy if causing throttling
   • Clear browser cache and restart browser
3. DRM Errors
   • Ensure DRM modules are enabled in your browser (Widevine in Chrome/Edge, PlayReady in Edge)
   • Check license server availability
   • Verify your device supports the required DRM system
   • Clear DRM cache (Chrome: chrome://settings/content/protectedContent)
4. No audio/video
   • Update browser to latest version
   • Check if codec is supported (AV1/HEVC may need extensions)
   • Disable hardware acceleration in browser settings
   • Test with different browser (Chrome recommended for best compatibility)

In practice, HLS is more widely supported natively (especially on iOS/tvOS), while DASH offers more flexibility.

Our MPD (DASH) Player is built by independent developers and open-source contributors with expertise in adaptive streaming protocols and web-based video playback.

• Development Philosophy: Create standards-compliant, privacy-respecting tools that work across all devices without installation
• Open Source Focus: Our core codebase is public, where users can report issues and submit feature requests
• Updates & Maintenance: Regular updates to address browser compatibility issues and community-reported bugs

Our mission is to provide a free, transparent, and private DASH playback solution that addresses the unique challenges of adaptive video streaming.
