Function Documentation

tivxSetGraphPipelineDepth()

vx_status VX_API_CALL tivxSetGraphPipelineDepth	(	vx_graph	graph,
		vx_uint32	pipeline_depth
	)

Indicates to the implementation the depth of the graph pipeline.

Parameters

[in]	graph	Graph reference
[in]	pipeline_depth	Pipeline depth; Max value is (TIVX_GRAPH_MAX_PIPELINE_DEPTH-1) else it will return an error

tivxGraphGetNode()

vx_node tivxGraphGetNode	(	vx_graph	graph,
		uint32_t	idx
	)

This API is used to get a reference to a node within a graph at a given index within the graph.

Use vxQueryGraph with attribute VX_GRAPH_NUMNODES to get number of nodes within a graph. This API can be called only on a verified graph. Node returned by this API is not reference counted and should not be released by the user.

Parameters

[in]	graph	graph handle
[in]	idx	node index, value from 0 .. value returned by vxQueryGraph(VX_GRAPH_NUMNODES) - 1

Returns

vx_node in case of success, else NULL
