Typedef Documentation

typedef enum nvros::_ConsumerType nvros::ConsumerType

Declares all EGL consumer types supported by NvMedia EGLStream library.

typedef struct nvros::_CudaEglParams nvros::CudaEglParams

Holds CUDA EGL related parameters.

You must pass a valid pointer of this structure when initializing CUDA consumer EGLStream. InitConsumer API, on successful execution, populates members of this structure. This structure is only required for CUDA consumer or CUDA producer.

typedef struct nvros::_EglUtilOptions nvros::EglUtilOptions

Holds required window system related parameters when initializing EGLStream.

You must populate valid data inside this structure while initializing EGLStream. This structure is only used when initializing EGLOutput consumer.

typedef struct nvros::_EglUtilState nvros::EglUtilState

Holds EGL related parameters.

You must pass a valid pointer of this structure when initializing EGLStream. EglStreamInit API, on successful execution, populates members of this structure.

typedef enum nvros::_OpMode nvros::OpMode

Declares modes of operation for EGLStream.

typedef enum nvros::_ProducerType nvros::ProducerType

Declares all EGL producer types supported by NvMedia EGLStream library.

typedef enum nvros::_WinSys nvros::WinSys

Declares all window systems supported by NvMedia EGLStream library.

Enumeration Type Documentation

enum nvros::_ConsumerType

Declares all EGL consumer types supported by NvMedia EGLStream library.

Enumerator
VIDEO_CONSUMER	Video consumer. This EGL consumer type is not yet supported in NvROS.
IMAGE_CONSUMER	Image consumer. This EGL consumer type is not yet supported in NvROS.
GL_CONSUMER	GL consumer. This EGL consumer type is not yet supported in NvROS.
CUDA_CONSUMER	CUDA® consumer. This EGL consumer type allows the contents in the EGLStream to be received as a CUDA compatible data type and processes it through a CUDA based algorithm.
EGLOUTPUT_CONSUMER	EGL output consumer. This EGL consumer type allows the contents in the EGLStream to be displayed on EGL output.
DEFAULT_CONSUMER	Default consumer. This is set to EGLOUTPUT_CONSUMER.
INVALID_CONSUMER	Invalid consumer type.

enum nvros::_OpMode

Declares modes of operation for EGLStream.

Enumerator
MAILBOX	EGLStream in mailbox mode.
FIFO	EGLStream in FIFO mode.
DEFAULT_OP_MODE	Default EGLStream mode. It is set to MAILBOX.

Definition at line 147 of file nvros_egl_utils.h.

enum nvros::_ProducerType

Declares all EGL producer types supported by NvMedia EGLStream library.

Enumerator
