C Libraries

The C bindings expose Media over QUIC to C and C++ applications. Built on top of the Rust moq-net crate via FFI, with no Rust toolchain required at link time.

Libraries

libmoq

A C-callable shared and static library exposing the MoQ pub/sub API. Header files are generated by cbindgen and ship alongside the prebuilt binaries.

Features:

• Static (libmoq.a) and dynamic (libmoq.so / libmoq.dylib / moq.dll) library targets
• Auto-generated C header (moq.h)
• No Rust runtime exposed to consumers
• Works with any toolchain that can link a C library (CMake, Make, Meson, etc.)

Installation

From source

git clone https://github.com/moq-dev/moq
cd moq/rs/libmoq
cargo build --release

The library will be in target/release/libmoq.a (static) and target/release/libmoq.{so,dylib,dll} (dynamic). The C header is emitted as target/release/moq.h.

From prebuilt releases

Prebuilt binaries are attached to each libmoq-v* release for the major Tier 1 targets.

Use cases

• C/C++ applications integrating MoQ without a Rust toolchain
• Bindings for other languages that aren't already covered by Python, Kotlin, Swift, or Go
• Legacy systems and embedded targets where pulling in Rust at build time is impractical
