In support of this, * libargus delivers images with EGLStreams, which are directly supported by other system components * such as OpenGL and Cuda, and which require no buffer copies during delivery to the consumer. * * - Expansive metadata along with each output image. * * - Support for multiple sensors, including both separate control over independent sensors and * access to synchronized multi-sensor configurations. (The latter are unsupported in the current * release. When support is added, it will be available on only some NVIDIA platforms.) * * - Version stability and extensibility, which are provided by unchanging virtual interfaces and * the ability for vendors to add specialized extension interfaces. * * Libargus provides functionality in a number of different areas: * * - Captures with a wide variety of settings. * * - Optional autocontrol (such as auto-exposure and auto-white-balance.) * * - Libraries that consume the EGLStream outputs in different ways; for example, jpeg encoding or * direct application access to the images. * * - Metadata delivery via both libargus events and EGLStream metadata. * * - Image post-processing such as noise reduction and edge sharpening. * * - Notification of errors, image acquisition start, and other events via synchronous event queues. * * Functionality not provided by libargus: * * - Auto-focus. (Planned to be added in a later release.) * * - Reprocessing of YUV images (such as that required by Android’s Zero Shutter Lag feature.) * * - Reprocessing of Bayer (raw) images. (Planned to be added in a later release.) * * @defgroup ArgusObjects Objects and Interfaces * This module provides a list of libargus objects and the interfaces that they support. * Children of objects in this list describe either child InterfaceProviders provided by * the object or specialized types of the object (ie. Event types). * @ingroup LibargusAPI * * @defgroup ArgusExtensions Extensions * This module provides a list of extensions currently available for libargus. * @ingroup LibargusAPI */ /** * @ifnot SWDOCS_L4T * @mainpage * Proceed to the \ref LibargusAPI module for libargus documentation. * @endif */ #include #include "Argus/UUID.h" #include "Argus/Types.h" #include "Argus/Stream.h" #include "Argus/BufferStream.h" #include "Argus/CameraDevice.h" #include "Argus/CameraProvider.h" #include "Argus/CaptureMetadata.h" #include "Argus/CaptureSession.h" #include "Argus/EGLImage.h" #include "Argus/EGLStream.h" #include "Argus/EGLSync.h" #include "Argus/Event.h" #include "Argus/EventProvider.h" #include "Argus/EventQueue.h" #include "Argus/Request.h" #include "Argus/Settings.h" #include "Argus/ReprocessInfo.h" #endif
