Class OutputFrameJoin

Namespace

easyar

Output frame merger. Used to merge output frames from multiple components into a single output frame. All members of this class are thread-safe. Note that connecting and disconnecting multiple inputs should not be done while data is flowing in, otherwise it may enter a state where it cannot output. (It is recommended to complete data stream connections before starting the Camera.)

OutputFrameJoin

Methods

input

Input port.

• c
• cpp
• java
• kotlin
• objective-c
• swift
• csharp

void easyar_OutputFrameJoin_input(easyar_OutputFrameJoin * This, int index, easyar_OutputFrameSink * * Return)

std::shared_ptr<OutputFrameSink> input(int index)

public @Nonnull OutputFrameSink input(int index)

fun input(index: Int): OutputFrameSink

- (easyar_OutputFrameSink *)input:(int)index

public func input(_ index: Int32) -> OutputFrameSink

public virtual OutputFrameSink input(int index)

Parameters

Name	Type	Description
index	Int32

Returns

Type	Description
OutputFrameSink

output

Output port.

• c
• cpp
• java
• kotlin
• objective-c
• swift
• csharp

void easyar_OutputFrameJoin_output(easyar_OutputFrameJoin * This, easyar_OutputFrameSource * * Return)

std::shared_ptr<OutputFrameSource> output()

public @Nonnull OutputFrameSource output()

fun output(): OutputFrameSource

- (easyar_OutputFrameSource *)output

public func output() -> OutputFrameSource

public virtual OutputFrameSource output()

Returns

Type	Description
OutputFrameSource

inputCount

Number of inputs.

• c
• cpp
• java
• kotlin
• objective-c
• swift
• csharp

int easyar_OutputFrameJoin_inputCount(easyar_OutputFrameJoin * This)

int inputCount()

public int inputCount()

fun inputCount(): Int

- (int)inputCount

public func inputCount() -> Int32

public virtual int inputCount()

Returns

Type	Description
Int32

create

Create. Use the default merger function. Its implementation takes the input frame from the first input, and takes the first result from each input. For each input, if there is no result, it takes an empty result. The first result from each input will be placed at the corresponding input index in the results of the final output frame.
