最受欢迎的直播+录屏+导播台应用 OBS 近日发布了 v30.0 版本的大更新，新版本带来了针对 WebRTC 的支持，用户可配合如 Google Meet、Zoom、Discord 在内，支持 WebRTC 的应用使用。
除了引入针对 WebRTC 的支持，本次更新还为 OBS for Mac 带来了史诗级增强：Mac 用户现在无需安装第三方虚拟声卡插件，即可直接使用 OBS 捕捉线路声音。新版 OBS 还支持了 macOS 上的虚拟相机功能，并能与所有应用程序配合使用（需 macOS 13）。
注意：如前所述，此版本删除了对Ubuntu 20.04、Qt 5和FFmpeg 4.4之前版本的支持。
