Libargus

Could you please provide documentation/information on libargus available jetson platform, information such as architecture/framework of libargus, information about tuning tools(as shown in the camera architecture), compatibility with other libraries or frameworks such as QT. This information is not available in the reference guide or documentation. Is libargus available only on jetson? How can I integrate libargus with other frameworks like QT in the user space if possible (other than producer - consumer model)?
