Ingest

Accept anything. From anywhere.

xMedia accepts live network streams, professional hardware signals, local media files, and streams from other xMedia nodes — all through a single unified source API.

Network Streams

SRT Low-latency reliable transport. Listener and caller modes.

RTMP / RTMPS Ingest from encoders, OBS, hardware switchers.

RTSP IP cameras and network video sources.

HLS / DASH Pull from CDN and origin servers.

UDP / RTP MPEG-TS over multicast and unicast.

Hardware & Local

NDI Discover and ingest NDI sources over LAN. Full metadata support.

SDI / HDMI Blackmagic Design DeckLink capture cards. 3G, 6G, 12G SDI.

Files MP4, MOV, MXF, TS and other container formats.

USB / Capture Devices V4L2 and DirectShow compatible devices.

Multi-node & Distributed

Stream state sync Track remote stream metadata without transferring media data.

Remote buffered ingest Subscribe to a remote node and buffer locally for preview or processing.

On-demand segment pull Fetch a specific time-range chunk from another xMedia node.

Multi-server topologies Chain ingest, processing, and output across multiple servers.

Processing Engine

Transcode, transform, and deliver

Every step in the pipeline produces a new named stream. Each derived stream can be monitored, buffered, or delivered independently — with hardware-accelerated encoding where available.

Capabilities

Everything a broadcast engineer needs

Video Mixer

Combine multiple input streams into a single composited output. Lay out tiles, apply PiP overlays, or build a software production switcher — all processed as a named stream.

Replay Buffer

RAM or disk-backed ring buffer on any stream. Frame-accurate seek, slow motion, reverse playback, and direct clip export to MP4 or TS from the browser.

Hardware Transcoding

Transcode any stream to any target codec and bitrate. Automatic NVIDIA CUDA and Intel Quick Sync acceleration. Each output is a new addressable stream.

Multi-destination Output

Simultaneously write to file, push to CDN, feed NDI or SDI, and serve a delayed playout — all from the same source, with independent buffer positions per output.

AI & Custom Filters

Apply graphic overlays, scale, crop, and mix multiple sources. Hook ML inference inline — object detection, auto-captions — without buffering frames to disk.

24/7 Continuous Recording

Unattended recording with automatic file segmentation by time or size. Seamless audio crossfade between segments for gap-free archive playback.

System Architecture

How xMedia is structured

Every source becomes a stream. Every processing result becomes a stream. One API gives you uniform access to all of them.

Control Interfaces

API-first by design

xMedia is built for automation. Every capability exposed in the Web UI is equally available through the API — with the same performance and latency guarantees.

WebSocket API

JSON · Binary · RPC

LIVE

Primary control interface. Full bidirectional RPC over WebSocket with JSON payloads. Subscribe to stream events, issue commands, get real-time status. Works from any language.

TransportWebSocket + JSON / Binary

PatternRPC + Event subscriptions

Default port8765

C / C++ Native API

LIVE

Deep integration for embedded use. Zero-copy access to stream data, direct frame callbacks, minimal overhead. Ideal for building products on top of xMedia.

Protobuf · High-performance

PLANNED

High-throughput alternative for service-to-service automation. Strongly typed Protobuf schema, bi-directional streaming, and lower overhead for high-frequency control loops.

Unreal Engine Integration

Virtual production,
natively connected.

Full xMedia control from inside Unreal Engine. Route live camera feeds into virtual scenes, publish composited output as streams, and sync everything to timecode — without leaving your VP workflow.

Full xMedia API available as UE Blueprint nodes
Ingest live video streams directly into virtual scene materials
Publish UE render output as an xMedia stream
Timecode sync with studio hardware and other devices

Use Cases

What engineers build with xMedia

Broadcast & Linear TV

Multi-feed ingest & live transcoding

Ingest multiple simultaneous SRT and NDI feeds, transcode each to target formats, and push to CDN or SDI outputs — all managed from a single server and a browser tab.

Sports & Live Events

Instant replay with frame accuracy

Buffer every camera feed continuously. Trigger replays at ±1-frame accuracy, play in slow motion, and export highlight clips to MP4 — without interrupting the live broadcast output.

OTT & VOD

24/7 recording & adaptive origin

Continuous segmented recording with seamless audio overlap between files. Simultaneously produce multiple bitrate ladders from one source for ABR HLS and DASH delivery.

Virtual Production · Roadmap

Unreal Engine live compositing

Planned UE plugin will enable full xMedia control from within Unreal — display live feeds on scene geometry, publish virtual camera output as streams, and sync the pipeline via LTC timecode.

Why xMedia

Built for what others leave out

Most media servers focus on delivery. xMedia starts at ingest and gives you full control at every step — including frame-accurate replay that no other server offers out of the box.
