1.0.0

First stable release

SysDVR-UVC is an Atmosphere sysmodule that turns your Nintendo Switch into a standard USB webcam (UVC).

Plug it into a PC and capture gameplay with ffplay, OBS, or v4l2 - no drivers, no client software.

Requirements

• Nintendo Switch with Atmosphere, HOS 5.0+
• A game with video capture support (recording icon visible)
• A data-capable USB-C cable
• WARNING : The original SysDVR sysmodule must NOT be installed : both compete for grc:d and usb:ds. Running both crashes the console at boot

Installation

• Unzip at the root of your SD card
• Activate the sysmodule with an overlay (e.g. ovlSysmodules) or any other sysmodule manager
• No need to reboot as sysmodule can be enable / disable on-the-fly
• Connect to PC, open the camera "SysDVR-UVC Capture" with a capture software

Usage

If ffplay is installed, use the ready-made low-latency launch scripts in the tools folder (switch-cam.sh for Linux, switch-cam.bat for Windows).

FFPLAY comes with FFMPEG binaries. Download them for smooth usage.

See the README for usage, latency tuning, and limitations.
