WebRTC Native Client Momo is an open-source, standalone media streamer powered by libwebrtc. Operating without a browser runtime, it captures and transmits ultra-low-latency video and audio streams directly across embedded systems, single-board computers, and desktop operating systems using native hardware acceleration.

Technical Overview of Momo

Momo distributes compiled, portable native binaries that run directly from the command line without traditional system installations or browser dependencies. The software interfaces with silicon-level video engines—including NVIDIA Video Codec, Intel VPL, Apple VideoToolbox, and V4L2 M2M—to deliver throughput capable of 4K streaming and high-speed 120 fps capture. Because it executes as a lightweight C++ native binary, processing stays focused on hardware-accelerated encoding and decoding rather than managing web page rendering overhead.

Core Features of Momo

Integrated signaling engine runs directly inside the client to establish instant, serverless peer-to-peer connections with web browsers.
Hardware-accelerated codec pipeline enables real-time encoding and decoding across modern formats including AV1, H.265 (HEVC), VP9, and H.264.
Simulcast transmission options pair with external signaling systems like OpenAyame and WebRTC SFU Sora for adaptive multi-bitrate delivery.
Data channel serial read and write capabilities route raw hardware telemetry over real-time peer connections with minimal latency.
Raw frame compatibility supports uncompressed camera input streams including YUY2, NV12, and direct Raspberry Pi libcamera sensors.

System Compatibility & Updates

Momo provides native binaries for Windows 11 (x86_64), macOS 14 and 15 (Apple Silicon arm64), Ubuntu 22.04 and 24.04 (x86_64), and Ubuntu 22.04 ARMv8 on NVIDIA Jetson platforms running JetPack 6 (including AGX Orin and Orin NX). It also supports Raspberry Pi OS bookworm 64-bit across Raspberry Pi 5, 4, 3, 2 Model B v1.2, and Zero 2 W. Recent updates refresh the core media engine to upstream libwebrtc m150 and integrate direct support for Raspberry Pi libcamera.

Why Choose Momo?

Momo eliminates the bloat and overhead of desktop web browsers by compiling WebRTC into an efficient, Apache 2.0-licensed native binary tailored for embedded robotics, servers, and IoT nodes. It pairs native silicon encoding with built-in P2P signaling, giving developers high-resolution, 120 fps streaming without vendor lock-in or licensing fees.
