You know that feeling when you need to ingest an RTMP push, hand it to a WebRTC viewer, record it to MP4, and also register a batch of Chinese-standard GB28181 cameras — and every off-the-shelf server does four of those five things? You end up either forking a C++ codebase you cannot maintain or gluing three servers together with FFmpeg processes. Monibuca's answer is to hand you the forwarding core and let you compile in only the protocol plugins you need. The trade is that you now own the build: the quick start is `go run -tags sqlite main.go`, not a single downloadable binary.
Think of it like a single whiteboard everyone in the room reads from, instead of photocopying the page for each person. A Publisher writes incoming audio and video frames into a RingBuffer; every Subscriber reads those same frames by reference, so nothing gets copied per viewer. Optional Transformer stages sit between the two for things like transcoding. Each protocol — RTMP, RTSP, HLS, WebRTC, SRT, GB28181 — is a plugin implementing an `IPlugin` interface, so you compile in only what you use. The clever and costly part is underneath: `doc/arch/reuse.md` documents a hand-built object pool (`ReuseArray`, `RecyclableMemory`, `PublishWriter`) because the old write path created multiple objects per call through reflection, and at 30fps that generated significant garbage-collection overhead. The redesign targets "Zero Object Creation" — and requires you to `defer allocator.Recycle()` yourself.
If you build video infrastructure in Go and need a protocol matrix that includes GB28181 or ONVIF camera ingest alongside normal RTMP-to-WebRTC delivery, this is one of the very few frameworks that covers it in one codebase. It is also worth reading if you want to see how someone fights Go's garbage collector in a hot path — `doc/arch/reuse.md` is 23,742 bytes of real reasoning. Not for you if you want a single static binary you drop on a box (take mediamtx), if AGPL-3.0 is a blocker for your commercial deployment, or if you need English-language maintainer support — 11 of the 16 open issues ...
Explore it for the architecture, be careful about betting a product on it. The engineering is real — a documented zero-copy ring buffer, a task lifecycle system, and two internals mature enough to be spun out as standalone libraries. But the vendor states V6 is "fully migrated from Go to Rust" and closed-source, commits on this branch fell from 449 in 2025 to 56 in 2026 so far, there has been no tagged release since v5.1.6 on 2025-12-30, and an OOM-causing RTSP memory leak (issue #393, filed 2026-03-24) still sits with zero comments. Treat it as stable-but-slowing code you would need to be willing to maintain yourself.
