Mux Data (launched 2017) is one of the dominant video QoE analytics platforms alongside Conviva, NPAW, Bitmovin Analytics and Datazoom. The SDK integrates into the player (web via hls.js/Shaka/Video.js plugins, iOS/Android via native SDKs, smart-TV via vendor SDKs) and ships every notable playback event — play, pause, seek, ABR switch, rebuffer, error, completion — to Mux's backend with metadata about the session (device, geo, CDN, content ID, player version).
The Mux dashboard aggregates these events into the standard QoE metrics — rebuffer ratio, startup time, video startup failures, exits before video start, average bitrate watched — and slices them by every dimension: per-content, per-CDN, per-ISP, per-device-type, per-region. Operators use it to spot regressions (a deploy caused a 20 % startup-time spike), diagnose CDN issues (one POP suddenly has 5× higher rebuffer ratio), and prioritise QoE improvement work.
Mux Data is particularly popular with developer-first OTT services because of clean SDKs, a programmable API, and integration with Mux's other products (Mux Video for managed encoding/streaming). For tier-1 OTT services, Conviva remains the default for its deeper enterprise integrations and longer history; Mux Data is increasingly chosen by mid-market and newer entrants. Both products produce the same fundamental metrics — the difference is workflow integration and pricing.

Video Streaming: A Complete Guide to Video Delivery: From ABR and CDNs to Players, WebRTC, DRM, and the Economics of Streaming
Mux Data tells you startup time, rebuffer ratio and exits before video start, but the numbers only help once you know which delivery change moves each one. This volume covers QoE metrics in detail, with player telemetry, ABR behaviour, stall recovery, CDN performance and how to tie QoE to delivery cost. Written by Nikolay Sapunov, CEO at Fora Soft.
