Which protocols does Go2rtc support for input and output (e.g., RTSP, WebRTC, HLS)?

Go2rtc has gained prominence in the smart home ecosystem for its flexibility and real-time performance. Designed to serve as a multiprotocol streaming proxy, Go2rtc acts as a universal bridge for a wide range of audio-video streaming formats. This capability allows users to simplify complex setups, consolidate video feeds, and route them to compatible clients such as Home Assistant, Frigate, or external web interfaces.

Its primary function lies in the ability to ingest, convert, and output video streams across various protocols. This compatibility offers a seamless way to unify devices that use different standards and make their feeds accessible in a standardized format. From RTSP to WebRTC, Go2rtc supports numerous input and output protocols, optimizing real-time performance and reducing latency for end users.

Real-Time Streaming Protocol (RTSP) Support

RTSP remains one of the most widely used protocols for network cameras and surveillance systems. Go2rtc natively supports RTSP as both an input and output protocol, allowing users to stream from IP cameras and broadcast these feeds to other devices or platforms.

Most consumer and enterprise-grade IP cameras support RTSP natively. By connecting these streams through Go2rtc, users can leverage advanced features such as transcoding, stream splitting, and latency control. This enables low-latency viewing through other formats like WebRTC or direct RTSP feeds in applications like VLC or Home Assistant.

RTSP output is particularly useful when connecting to traditional media players or software that requires persistent, low-bandwidth streams. The protocol’s design for control over streaming sessions also helps in cases where pause, rewind, or seek features are needed.

Web Real-Time Communication (WebRTC) Integration

WebRTC is a modern peer-to-peer protocol that facilitates low-latency, browser-based communication. Go2rtc excels in its WebRTC support, allowing users to convert RTSP or other streams into WebRTC-compatible formats. This functionality is crucial for real-time monitoring and instant feedback, especially in smart home environments.

By leveraging WebRTC, Go2rtc can deliver sub-second latency video feeds directly to web browsers without the need for plugins or third-party players. This makes it ideal for mobile access and fast-response applications, such as security camera feeds or doorbell monitoring.

WebRTC output in Go2rtc is compatible with various clients including Home Assistant’s dashboard, enabling smooth and efficient viewing experiences. Additionally, WebRTC input is supported to a limited degree, mainly through relaying peer-to-peer media from browser clients or other real-time sources.

HTTP Live Streaming (HLS) Availability

HLS is a protocol developed by Apple for adaptive bitrate streaming. Unlike WebRTC, which prioritizes low latency, HLS focuses on wide compatibility and smooth playback over varying network conditions. Go2rtc provides HLS output, giving users access to media streams through nearly any web-enabled device.

While HLS introduces higher latency due to its segment-based delivery model, it remains useful for applications that require reliable playback over long distances or across unstable networks. Go2rtc’s ability to generate HLS output from RTSP or other live sources helps bridge the gap between real-time devices and slow or bandwidth-limited clients.

Its use is common in media dashboards, remote viewing portals, and browser-based surveillance viewers. The inclusion of HLS output enables Go2rtc to act as a true streaming hub for diverse environments.

Secure Reliable Transport (SRT) Compatibility

SRT has become a standard in broadcast and remote streaming workflows, focusing on secure, high-quality delivery over public networks. Go2rtc includes basic support for SRT as an output format, which is valuable for long-haul or mission-critical stream transport.

The key benefit of SRT is its ability to compensate for packet loss, jitter, and fluctuating network conditions. This makes it ideal for sending video from Go2rtc to a remote server or cloud infrastructure without sacrificing stream integrity. Its secure design also adds a layer of encryption, enhancing the safety of transmitted content.

SRT input support within Go2rtc is still evolving but serves niche applications where high-efficiency, encrypted video transport is needed.

MPEG-TS (Transport Stream) Streaming Options

MPEG-TS is a format commonly used for broadcasting and IPTV applications. Go2rtc can handle MPEG-TS as both an input and output protocol under specific conditions, depending on the stream source and configuration.

This support enables integration with IPTV networks, satellite receivers, and traditional broadcasting setups. It allows Go2rtc to serve as a bridge between raw MPEG-TS feeds and modern streaming platforms, facilitating live re-broadcasts, transcoding, and protocol conversion.

Outputting in MPEG-TS can also be beneficial when feeding content into devices that require TS-compliant streams, including older hardware players and custom embedded systems.

Real-Time Messaging Protocol (RTMP) Connectivity

RTMP, once dominant in the online streaming industry, is still relevant in various broadcasting scenarios. Go2rtc includes RTMP support primarily as an input protocol, enabling users to pull streams from streaming servers or cloud platforms like YouTube Live, Facebook Live, or custom RTMP endpoints.

This feature allows integration of public or private broadcasts into smart home systems or internal media players. RTMP output, while limited, can be configured in custom setups to serve content to platforms that demand RTMP ingestion.

Despite its age, RTMP remains a useful inclusion for compatibility with legacy streaming setups or online streaming workflows.

Compatibility With Local Media Files

Go2rtc extends its utility by supporting local media file playback. Files in formats like MP4, MKV, or TS can be configured as virtual stream sources, making it possible to broadcast prerecorded content using live streaming protocols such as RTSP or HLS.

This function is particularly useful for testing, simulation, or scheduled playback applications. It allows administrators to create hybrid media environments where both live and prerecorded footage are streamed through the same infrastructure.

File playback also supports looping and timeline control, offering flexibility in content delivery.

Support for Onvif-Compatible Cameras

ONVIF is not a streaming protocol itself but a device management standard that often points to RTSP endpoints. Go2rtc indirectly supports ONVIF-compatible cameras by allowing automatic RTSP discovery and integration.

This allows plug-and-play configuration for a wide range of IP cameras, reducing the need for manual RTSP URL input. Once detected, these streams are fed into Go2rtc’s core engine and can be routed to any of the supported output protocols.

In environments with many security cameras, ONVIF support simplifies onboarding and central management.

Transcoding Capabilities Across Protocols

While protocol conversion is a key feature, Go2rtc also supports transcoding through FFmpeg integration. Transcoding allows the transformation of video codecs, resolutions, and bitrates to match output protocol requirements or client capabilities.

This process enables compatibility across devices that may not support the original input stream format. For example, a high-bitrate RTSP stream can be transcoded to a lower bitrate HLS or WebRTC stream for mobile viewing.

Though transcoding is resource-intensive, it significantly enhances flexibility and user experience, particularly on lower-end client devices.

Multistream Routing and Relay Management

Go2rtc is capable of handling multiple streams concurrently and routing them to different output protocols based on client requests. This multistream capability makes it suitable for centralized streaming hubs in large-scale installations or mixed-protocol environments.

The system dynamically switches streams between protocols as needed. For example, the same RTSP input from a camera can be broadcast as WebRTC to a browser, HLS to a media dashboard, and MPEG-TS to a recording system, all simultaneously.

This real-time relay mechanism allows for efficient bandwidth usage and ensures broad accessibility.

Use Cases in Home Assistant and Frigate

Home Assistant, one of the most popular smart home platforms, leverages Go2rtc for low-latency camera integrations. WebRTC output is particularly beneficial for providing real-time previews within Home Assistant dashboards. HLS and RTSP streams also offer fallback options for wider compatibility.

Frigate, an AI-powered NVR system, also benefits from Go2rtc’s support of low-latency protocols. The conversion of high-resolution RTSP streams into more manageable formats enables better object detection, alerting, and storage efficiency.

These integrations highlight Go2rtc’s role as the glue between cameras, smart platforms, and client-facing applications.
