The challenge
Modern streaming players and CDNs are flying blind without server-side context. CMSD (Common Media Server Data, standardized as CTA-5006) closes that gap — but most streaming servers don't support it natively.
The solution
Scout is a plugin that automatically injects CMSD-Static metadata into HTTP responses for both HLS and DASH streams using the standard CMSD key set. It can also compute per-stream PSNR, SSIM, and optional VMAF quality scores (MQA).

All you need for streaming observability

Five CMSD-Static keys
Duration (d), bitrate (br), object type (ot), streaming format (sf), and stream type (st) per CTA-5006.
HLS + DASH support
Works with both streaming protocols on Ant Media Server and Wowza Streaming Engine.
Flexible delivery
Inject metadata as HTTP response headers, inside the manifest body, or both.
Media Quality Assessment
Per-stream PSNR, SSIM, and optional VMAF scores for real-time encoding quality monitoring
Configurable scope
Apply metadata to manifests only, segments only, or both — per application .
Web UI with hot-reload
Configure and manage through a browser-based interface, no server restart needed.

Up and running in Three steps
