apk update
apk add librtmp2 librtmp2-dev

Fedora / DNF repository

Fedora 44 packages are built for x86_64, aarch64, ppc64le, and s390x. Packages and repository metadata are signed with the OpenRTMP GPG key.

sudo tee /etc/yum.repos.d/openrtmp.repo >/dev/null <<'EOF'

sudo dnf install librtmp2 librtmp2-devel

Enterprise Linux / DNF repository

Enterprise Linux 9 and 10 packages are intended for RHEL-compatible systems including RHEL, Rocky Linux, and AlmaLinux. Supported architectures are x86_64, aarch64, ppc64le, and s390x.

sudo tee /etc/yum.repos.d/openrtmp.repo >/dev/null <<'EOF'

sudo dnf install librtmp2 librtmp2-devel

openSUSE / Zypper repository

openSUSE Leap 16.0 packages are built for x86_64, aarch64, ppc64le, and s390x.

sudo rpm --import https://packages.openrtmp.org/openrtmp.asc
sudo zypper addrepo --refresh \
  "https://packages.openrtmp.org/rpm/opensuse/16.0/$(uname -m)" openrtmp
sudo zypper refresh
sudo zypper install librtmp2 librtmp2-devel

Arch Linux repository

The Arch Linux repository targets the official x86_64 architecture. Packages and repository databases are signed with the OpenRTMP GPG key.

curl -fsSL https://packages.openrtmp.org/openrtmp.asc -o /tmp/openrtmp.asc
key="$(gpg --show-keys --with-colons /tmp/openrtmp.asc | awk -F: '$1 == "fpr" { print $10; exit }')"
sudo pacman-key --add /tmp/openrtmp.asc
sudo pacman-key --lsign-key "$key"

sudo tee -a /etc/pacman.conf >/dev/null <<'EOF'

sudo pacman -Syu librtmp2

Homebrew

The repository also acts as a Homebrew tap. Because the GitHub repository is named packages rather than homebrew-packages, add it with its explicit remote once:

brew tap openrtmp/packages https://github.com/OpenRTMP/packages
brew install openrtmp/packages/librtmp2

Run the brew tap command with the explicit URL first. brew install openrtmp/packages/librtmp2 on its own will try to auto-tap using Homebrew's default naming convention (homebrew-packages), which doesn't exist and fails to clone.

Homebrew 6.0+ requires third-party taps to be trusted before their formulae are loaded (Tap Trust), so brew tap may print Invalid formula / untrusted tap warnings the first time — this is expected. Installing the fully qualified formula name (brew install openrtmp/packages/librtmp2) trusts just that formula automatically. To trust the whole tap up front instead, run brew trust openrtmp/packages.

The formula is updated automatically when a new librtmp2 release is published. On macOS Sequoia, Tahoe, and Golden Gate (arm64) - plus Sequoia and Tahoe on Intel, where GitHub still offers an Intel runner - brew install fetches a precompiled bottle instead of building from source; other platforms, including macOS Sonoma (whose GitHub Actions runner is deprecated), build librtmp2 locally.

Windows

Signed Windows ZIPs are built for both x86_64 and arm64 for every librtmp2 release with native Windows support (releases up to v0.11.0 do not build on Windows and have no Windows packages). Each architecture is built, tested (including RTMP and RTMPS loopback tests) and checked on a native runner of that architecture before it is published.

Each ZIP contains bin\librtmp2.dll, the import library lib\librtmp2.dll.lib, the static library lib\librtmp2.lib, the C header include\librtmp2\librtmp2.h, README, the librtmp2 license, and the OpenSSL license notice. OpenSSL is linked statically, so the DLL needs only Windows system DLLs plus the Microsoft Visual C++ Redistributable (2015-2022) that every Rust/MSVC DLL uses. Each archive has a SHA-256 checksum and an OpenPGP signature.

The verification example below requires GnuPG (gpg) to be installed. The trusted OpenRTMP package-signing key fingerprint is 615A20712AA690E917D6DCEF75E87340DA09771D.
