Install

One command, any distro

Detecting your system...
bash
$ git clone https://github.com/Hkshoonya/nvidia-broadcast-linux.git
$ cd nvidia-broadcast-linux
$ ./install.sh

Works on all distros. The installer auto-detects your package manager and installs dependencies. Re-running `./install.sh` upgrades the existing install in place.

bash
# Download and verify v1.5.2
$ (
set -euo pipefail
WORKDIR=$(mktemp -d)
cd "$WORKDIR"
$ BASE=https://github.com/Hkshoonya/nvidia-broadcast-linux/releases/download/v1.5.2
$ PACKAGE=nvbroadcast_1.5.2-1_all.deb
$ wget --https-only "$BASE/$PACKAGE" "$BASE/nvbroadcast-native-upgrade" "$BASE/SHA256SUMS.packages"
$ awk -v package="$PACKAGE" '$2 == package || $2 == "nvbroadcast-native-upgrade" { print; found++ } END { exit found != 2 }' SHA256SUMS.packages | sha256sum -c -
$ chmod 755 nvbroadcast-native-upgrade
# Protected upgrade when installed; normal package-manager path when clean
$ if dpkg-query -W -f='${db:Status-Abbrev}' nvbroadcast 2>/dev/null | grep -q '^i'; then sudo ./nvbroadcast-native-upgrade "./$PACKAGE"; else sudo apt-get install --yes --no-remove "./$PACKAGE"; fi
)

For Ubuntu, Debian, Pop!_OS, Linux Mint, and derivatives. The commands above verify both downloads and automatically protect native v1.4.0-and-older upgrades with the release-bound helper. Read the verification details

bash
# Download and verify v1.5.2
$ (
set -euo pipefail
WORKDIR=$(mktemp -d)
cd "$WORKDIR"
$ BASE=https://github.com/Hkshoonya/nvidia-broadcast-linux/releases/download/v1.5.2
$ PACKAGE=nvbroadcast-1.5.2-1.noarch.rpm
$ wget --https-only "$BASE/$PACKAGE" "$BASE/nvbroadcast-native-upgrade" "$BASE/SHA256SUMS.packages"
$ awk -v package="$PACKAGE" '$2 == package || $2 == "nvbroadcast-native-upgrade" { print; found++ } END { exit found != 2 }' SHA256SUMS.packages | sha256sum -c -
$ chmod 755 nvbroadcast-native-upgrade
# Protected upgrade when installed; normal package-manager path when clean
$ if rpm -q nvbroadcast >/dev/null 2>&1; then sudo ./nvbroadcast-native-upgrade "./$PACKAGE"; else sudo dnf install --assumeyes "./$PACKAGE"; fi
)

For Fedora, RHEL, CentOS, and Rocky. The commands above verify both downloads and automatically protect native v1.4.0-and-older upgrades with the release-bound helper. Read the verification details

bash
# Snap Store (released separately after validation)
$ sudo snap install nvbroadcast
$ sudo snap refresh nvbroadcast

For systems with Snap support. Snap Store updates are released separately after artifact inspection, provenance verification, Store review, and candidate testing. v1.5.2 is now available in the stable channel; `snap refresh nvbroadcast` upgrades in place with camera-format recovery, strict-Snap meeting transcription, verified runtime ownership, and cumulative contributor credits. The arm64 Snap remains CPU-only.

bash
# Install system deps then run the installer
$ sudo pacman -S python gtk4 libadwaita gstreamer gst-plugins-base gst-plugins-good gst-plugins-bad v4l-utils
$ git clone https://github.com/Hkshoonya/nvidia-broadcast-linux.git && cd nvidia-broadcast-linux && ./install.sh

For Arch, Manjaro, EndeavourOS. Arch wiki: v4l2loopback

zsh
# macOS (Apple Silicon)
$ git clone https://github.com/Hkshoonya/nvidia-broadcast-linux.git
$ cd nvidia-broadcast-linux
$ ./install_macos.sh
# Upgrade later: install the newer .pkg after this one-time source setup

Existing configured installs can download the update package: NVBroadcast-1.5.2-1.pkg
Requires Apple Silicon, macOS 13+, Homebrew, Python 3.11-3.13, and OBS Studio. After installing OBS, open it once, start and stop Virtual Camera, then close OBS. Intel macOS is not included in v1.5.2 because a secure current MediaPipe wheel is unavailable.

Linux

  • Any distro (Ubuntu, Fedora, Arch, Pop!_OS...)
  • NVIDIA GTX 1060+ for GPU modes
  • Python 3.11+, GStreamer, GTK4
  • PipeWire for virtual mic

macOS

  • macOS 13 Ventura or newer
  • Apple Silicon (M1+) required
  • Homebrew, Python 3.11-3.13
  • OBS Studio for virtual-camera output
  • CPU modes (no NVIDIA needed)

Camera + Audio

  • USB webcam, 720p+ recommended
  • Any microphone (USB, built-in)
  • 360p to 4K supported
Open Source Sustainability

Help keep NV Broadcast maintained

I lead and maintain NV Broadcast with help from community reports, testing, documentation, ideas, and code. The first goal is 10 monthly sponsors so growing usage can be matched with predictable time for compatibility fixes, contribution review, package testing, and reliable releases.
