Video Player QoE Analytics

Understand how every viewer experiences your video service — from inside the player.

For OTT service providers, ISPs with IPTV services, and app developers who need real-time visibility into video playback quality across their subscriber base. Lightweight player SDKs collect QoE telemetry from every session, every device, every viewer.

The Challenge

You don't know what your viewers actually experience

Server-side analytics show you bitrate ladders served and CDN response times, but they miss what happens in the player: stalling that the CDN doesn't see, quality drops during resolution switches, slow startup on certain devices, and silent failures that viewers tolerate until they churn.

Our Approach

Client-side QoE telemetry from every playback session

Surfmeter Player SDKs integrate into your video application and collect real-time quality data from the player itself. Available for ExoPlayer (Android), AVPlayer (iOS), Video.js, THEOplayer, Shaka Player, and HTML5 video — the SDK captures P.1203 MOS scores, stalling events, loading delays, and quality switches from every viewer session.

Key Capabilities

What you can do with this solution

Multi-Platform Player Support

SDKs for ExoPlayer (Android), AVPlayer (iOS), Video.js, THEOplayer, Shaka Player, Brightcove, and HTML5 video. Cover your entire device ecosystem.

Real-Time Session Monitoring

Monitor active playback sessions in real time. See quality metrics as they happen, not hours later in batch reports.

ITU-Standardized Video MOS

Every session gets a P.1203 MOS score that predicts viewer satisfaction — going beyond raw metrics to a standardized quality rating.

Lightweight Integration

Minimal SDK footprint with background data transmission. No impact on playback performance or user experience.

Proven in Practice

Multi-platform QoE monitoring for in-house IPTV service

DNS:Net wanted to understand quality differences across their Android, iOS, and web player implementations, and discover users who were experiencing poor quality before they complained. With the Surfmeter Player SDK, they gained visibility into client-side quality metrics across all platforms.

Results

Added clients-side SDKs to all three platforms
Implemented a dashboard showing the lowest performing sessions across all platforms
Verified downstream issues due to network interchanges which were not visible in server-side logs

WDR, one of Germany’s largest public broadcasters, uses Surfmeter to monitor the delivery quality of their streaming services from the viewer’s perspective. Beyond continuous CDN performance monitoring, WDR uses Surfmeter to validate new player versions, compare stream configurations, and verify that encoding changes deliver the expected quality improvements before rolling them out to millions of viewers.

Results

Continuous monitoring of CDN delivery quality for WDR’s streaming services
Validated new player versions and stream configurations before rollout
Compared encoding settings and verified quality improvements objectively
Identified delivery issues across different ISPs and regions

Business Benefits

Real outcomes for your business

Reduce Viewer Churn

Detect quality issues that drive viewers away before they cancel. Many quality problems are silent — viewers leave without complaining.

Optimize Encoding & Delivery

Use real viewer data to tune bitrate ladders, encoding settings, and CDN configuration for maximum quality.

Device-Specific Insights

Understand which devices, OS versions, and player configurations deliver the best experience and which need attention.

Standardized Quality Scoring

Report viewer quality using ITU-standardized MOS — a universally understood metric for executive reporting and benchmarking.

How It Works

From SDK integration to quality insights

Surfmeter Player SDKs are lightweight libraries that attach to your existing video player with minimal code changes.

1

Add the SDK

Integrate the appropriate Player SDK for your platform: npm package for web players, AAR for Android, XCFramework for iOS. A few lines of initialization code.

2

Automatic data collection

The SDK observes player events (stalling, quality changes, errors) and collects telemetry at configurable intervals — transparently, in the background.
