Hola a todos, en este tutorial veremos las secuencias de comandos para OBS en Lua.

Las secuencias de comandos en OBS han estado disponibles desde la versión 21, en este momento la versión más reciente 26.0.0-rc3 está disponible para probar. La actualización incluye una cámara web virtual (por ahora solo en Windows), una interfaz de usuario mejorada, la capacidad de tomar una captura de pantalla de cualquier fuente (KDPV se hizo con utilizando esta función).
