Macro Definition Documentation

#define TIVX_DEFAULT_GRAPH_TIMEOUT (TIVX_EVENT_TIMEOUT_WAIT_FOREVER)

Default timeout value for graph level control event ACK waits. This is the default timeout value used within the following APIs.

Definition at line 38 of file vx_graph.h.

#define TIVX_GRAPH_PARAMETER_ENQUEUE_FLAG_PIPEUP (0x00000001u)

Flag used with tivxGraphParameterEnqueueReadyRef to indicate that this enqueue call if for pipeup phase.

Typically used only with source nodes which have a pipeup requirement

Definition at line 49 of file vx_graph.h.

vx_status tivxGraphParameterEnqueueReadyRef	(	vx_graph	graph,
		vx_uint32	graph_parameter_index,
		vx_reference *	refs,
		vx_uint32	num_refs,
		vx_uint32	flags
	)

Same as vxGraphParameterEnqueueReadyRef except that it take an additional TIOVX specific flag parameter.

For valid values of flag see

TIVX_GRAPH_PARAMETER_ENQUEUE_FLAG_PIPEUP The tivxGraphParameterEnqueueReadyRef API is needed if explicitly enqueueing and dequeueing from a capture node graph parameter that has set the VX_KERNEL_PIPEUP_OUTPUT_DEPTH using the vxSetKernelAttribute API. The tivxGraphParameterEnqueueReadyRef must be called for the num_bufs given as the VX_KERNEL_PIPEUP_OUTPUT_DEPTH. This API differs from vxGraphParameterEnqueueReadyRef in that it does not additionally schedule a graph execution. In the case that this API is not used at the capture node graph parameter, the teardown of the graph will pend as it will be waiting on graph executions that have not completed.

Parameters

[in]	graph	Graph reference
[in]	graph_parameter_index	Graph parameter index
[in]	refs	The array of references to enqueue into the graph parameter
[in]	num_refs	Number of references to enqueue
[in]	flags	Flag to control behavior of the operation

Return values

VX_SUCCESS	No errors.
VX_ERROR_INVALID_REFERENCE	graph is not a valid reference OR reference is not a valid reference
VX_ERROR_INVALID_PARAMETERS	graph_parameter_index is NOT a valid graph parameter index
VX_FAILURE	Reference could not be enqueued.
