Hardware-Accelerated Window capture (NVIDIA FBC) in OBS-Studio

Posted on Sat 28 August 2021 in Software • 1 min read • obs-studio nvidia window-capture

For getting hardware-accelerated window capture on obs-studio, first we need to patch the nvidia-driver in using https://github.com/keylase/nvidia-patch. Please note that before applying the patch, please ensure that your driver version is supported. The installed driver version can be seen by issuing nvidia-smi command.

Next, we need to install a obs-studio plugin for Nvidia FBC API. The source code for the plugin is available at https://gitlab.com/fzwoch/obs-nvfbc. Download the source code and build it. The compiled nvfbc.so file is copied to plugins/nvfbc/ folder.

In OBS-Studio, a new source will appear for NVIDIA FBC. Enjoy the hardware-accelerated window capture.
