OBS Studio, the popular free open-source live streaming software, announced new major 30.2.0 release a day ago.

The new release has some improvements for Linux support. They include native NVENC encoder interface for NVIDIA GPU hardware accelerated encoding, and NVENC AV1 support. And, Linux shared texture support to the NVENC encoder, QuickSync encoder, as well as VA-API encoder.
