STANAG 4609 Player .NET SDK  Version 3.10.0


STANAG Player SDK is an "ITAR-free" library that provides STANAG TS stream/file playback, decoding / KLV extraction and frame grabbing. Used in both military and civilian applications, this .Net library allows developers to create multi-channel applications that receive and process streaming video coming from UAV platforms and extract/decode the MISB metadata. The SDK has a rich feature set that can be easily customized, providing a robust and cost-effective solution for any STANAG 4609 related development project.
STANAG Player SDK is based on StCore runtime, shared between both the player and the injector.


Main features:

  • STANAG 4609 network stream (TS over UDP and TS over RTP) playback.
  • STANAG 4609 file playback.
  • STANAG 4609 HLS (local files / LAN / clound / StanagOnDemand VMS) playback.
  • STANAG 4609 DVR mode* - Live / Pause, Trick mode (Step Forward / Backward, Seek), Back to Live.
  • Frame accurate (video frames / Klv packets)
  • ASYNC and SYNC Klv
  • MPEG TS (MPEG2/H.264 payload + MISB 0601.X / 0102.X, 0806, 0903.4(VMTI), 1204, 1601 metadata) support.
  • Synchronized Raw (compressed / uncompressed (RGB, YUV, Grayscale)) video frames, KLV (raw buffer + decoded metadata) and private data callback. Frame accurate sync.
  • VMTI (Video Moving Target Indicator and Track Metadata) MISB 0903.X support.
  • MISB to JSON / GeoJSON decoding.
  • Closed caption KLV extraction and transcoding.
  • C# sample code (Console, WinForms, Wpf).
  • Simple Video Overlay WPF Control.
  • "ITAR-free"

Please note, the SDK is provided in 64 bit mode.

DVR mode requires an external recorder (sold separately).

Getting Started with Stanag Player SDK

This section contains information designed to get you started quickly.

Make sure you have all prerequisites in place. For more info on Prerequisites. Also, the STANAG Player SDK is a 64 bit SDK, so please build your application accordingly.

The STANAG Player SDK comes with a demo application, so we'll start with compiling and running it with the STANAG file or stream as a source.

Console Demo Application

Examples of usage the STANAG Player SDK for some basic tasks:

File / Network Stream Playback and Klv Extraction

Video / Data synchronization

HLS support.


DVR mode.

HW Acceleration

HW accelerated decoding for video playback. The SDK leverages multiple technologies such as DXVA, CUDA, QuickSync, and D3D11VA to enhance the decoding process.
