webrtc-javaJava native interface for WebRTC

Build real‑time audio, video, and data with a clean Java API.

Cross-platform, Native Speed

One Java API on Windows, macOS and Linux, with prebuilt native libraries. A thin JNI layer keeps the overhead between Java and native code minimal.

Introduction

Audio and Video Streaming

Capture audio and video from microphones and cameras, or feed your own media sources into a call.

Media devices

Screen Sharing

Share application windows or the full desktop with minimal setup, and send them like any other video stream.

Desktop capture

Data Channels

Reliable or unreliable, ordered or unordered SCTP data channels for messaging, file transfer and app signaling.

Data channels

Hardware Video Codecs

Encode and decode H.264, H.265, VP9 and AV1 on the GPU through NVENC and NVDEC, Media Foundation, VA-API and VideoToolbox, with fallback to software.

Hardware codecs

Custom Video Codecs

Plug video encoders and decoders written in Java into WebRTC, to bring in a codec of your own or a hardware encoder from another library.

Video codecs

Video Processing

Change, replace or drop each camera or desktop frame before it is sent, for background blur, overlays, mirroring or hiding part of the screen.

Processing frames

End-to-End Encryption

Encoded transforms let Java code read, change or drop every encoded frame, like insertable streams in the browser, for encryption, metadata and analysis.

Encoded transforms

Send Pre-encoded Media

Send frames that are already encoded, such as an IP camera's H.264 stream or a recording, without encoding them again in WebRTC.

Injecting frames

Media File Playback

Play video and audio files or RTSP streams into a peer connection. The optional media module decodes with FFmpeg and keeps audio and video in sync.

Media files

Call Recording

Record what a peer connection sends or receives into MKV, WebM or MP4 files, without re-encoding, at next to no CPU cost and in the exact quality of the call.

Recording

Statistics and Monitoring

Read WebRTC stats such as bitrate, packet loss, jitter, round-trip time and frame rate to monitor and tune media quality.
