xMedia SDK — built on 15 years of broadcast infrastructure

Core concept

A framework, not a library.

xMedia SDK is built around a tree of processing nodes. Each node is a module — a decoder, mixer, recorder, streamer. You connect modules into a pipeline. The framework handles data flow, threading, synchronization, and inter-node messaging automatically.

Ingest

SRT / RTMP / HLS NDI · SDI · WebCam File: MP4 / TS / MXF WebRTC (SFU/MCU)

Process

Decode / Demux Scale · FPS · Resample Mix · Overlay · CG Chroma Key · Effects

→

Buffer / Store

Replay buffer (RAM/disk) 24/7 recording Playlist / Scheduler Subtitle encode/decode

Output

SRT · RTMP · NDI · SDI WebRTC (SFU/MCU) HLS / DASH / DRM File: MP4 / TS / MXF

🧩

Modular

Pick only the modules you need — Base, Playlist, Mixer, Replay, CG, Chroma Key, Writer, xNetwork, Subtitles. Each is independent. Add capabilities without touching existing code.

🌐

Cross-platform

One codebase. Windows, Linux, macOS. The same API, the same module interfaces, the same behavior — whether you deploy to a cloud VM, on-prem appliance, or edge device.

🔤

Multi-language

C++, C#, Python — all share the same module API and interfaces. Control any pipeline remotely via WebSocket from any language or platform, including browsers.

⚡

Built for speed

Codec integration, hardware acceleration, SRT/NDI/SDI support, sync, buffering — already built. You compose pipelines from ready modules, not implement infrastructure from scratch.

Use cases

One framework. Many systems.

xMedia SDK is the infrastructure layer inside broadcast tools, OTT platforms, sports replay systems, MAM solutions, and security software.

Broadcast & Playout

Live production & channel automation

Ingest live feeds and file assets into a single pipeline. Mix sources, overlay CG graphics, encode to broadcast specs, push to SDI, NDI, and CDN simultaneously. Add the Playlist module for schedule-driven channel automation — one codebase runs the whole channel.

BasePlaylistMixerCG (HTML5)WriterxNetwork

Live Sports

Instant replay & slow-motion

Buffer every ISO camera feed from the moment broadcast starts. The moment the play ends — seek to any frame, scrub at any speed, export the clip. All frame-accurate, controlled via API from any operator interface you build on top.

BaseReplayMixerWriter

OTT & Media Servers

Scalable ingest and delivery platform

Build the ingest and processing core of an OTT platform or media server. Multi-bitrate transcoding, DRM-ready packaging, delivery to unlimited endpoints — all in one pipeline, one codebase, deployable on any OS.

BaseWriterxNetworkWebSockets

MAM & Archive

Recording, browse & clip workflows

Continuous 24/7 recording segmented into files. Read from a file that's currently being written. Frame-accurate clip access for browse and export workflows. Subtitle decode for archive search and indexing.

BaseReplayWriterSubtitle modules

Video Surveillance & Security

Distributed camera processing at scale

Ingest RTSP/ONVIF streams from IP cameras across your network. Process, record, and distribute video to monitoring stations, archive, and remote viewers. Lightweight per-node footprint — runs headless on Linux appliances, managed remotely via WebSocket API.

BaseWebSocketsWriterxNetwork

RTSP / ONVIF ingest from any IP camera

Multi-stream recording with segmentation

Live distribution to monitoring stations

Remote management via WebSocket — no GUI required

Headless Linux deployment, minimal footprint

SDK modules

Modular by design. Add capabilities without rewriting.

Each module is a self-contained unit with a clean API. Add it to your pipeline when you need it — the rest of your system doesn't change.
