Class SpinnakerSourceBlock

Namespace

VisioForge.Core.MediaBlocks.Sources

Assembly

VisioForge.Core.dll

Spinnaker source block for FLIR/Teledyne industrial and scientific cameras using the Spinnaker SDK. Provides high-performance image acquisition from FLIR machine vision cameras for thermal imaging, scientific analysis, industrial inspection, and computer vision applications with advanced camera control and synchronization features. Implements the VisioForge.Core.MediaBlocks.Sources.SourceMediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

Constructors

SpinnakerSourceBlock(SpinnakerSourceSettings)

Initializes a new instance of the VisioForge.Core.MediaBlocks.Sources.SpinnakerSourceBlock class with custom camera settings. Configures the Spinnaker source for FLIR camera acquisition with specified parameters.

public SpinnakerSourceBlock(SpinnakerSourceSettings settings)

Parameters

settings SpinnakerSourceSettings

The Spinnaker settings controlling camera selection, image format, and acquisition parameters.

Properties

Input

Gets the primary input pad (none for source blocks that capture from cameras).

public override MediaBlockPad Input { get; }

Property Value

MediaBlockPad

Inputs

Gets all input pads available on this block (none for source blocks).

public override MediaBlockPad[] Inputs { get; }

Property Value

MediaBlockPad[]

Output

Gets the primary video output pad for the camera stream.

public override MediaBlockPad Output { get; }

Property Value

MediaBlockPad

Outputs

Gets all output pads available on this block (single video output for camera).

public override MediaBlockPad[] Outputs { get; }

Property Value

MediaBlockPad[]

Settings

Gets or sets the Spinnaker configuration settings that control camera parameters and acquisition mode.

public SpinnakerSourceSettings Settings { get; set; }

Property Value

SpinnakerSourceSettings

Type

Gets the media block type identifier for Spinnaker source operations.

public override MediaBlockType Type { get; }

Property Value

MediaBlockType

Methods

Build()

Builds and initializes the Spinnaker source within the pipeline context. Connects to FLIR camera, configures acquisition parameters, and prepares video output for downstream processing.

public override bool Build()

Returns

bool

true if the Spinnaker source was successfully built and configured; otherwise, false.

CleanUp()

Cleans up all resources associated with the Spinnaker operations, including camera handles and image buffers.

public void CleanUp()

Dispose(bool)

Releases unmanaged and managed resources used by the Spinnaker source. Properly closes camera connection and disposes of GStreamer elements and acquisition resources.

protected override void Dispose(bool disposing)

Parameters

disposing bool

true to release both managed and unmanaged resources; false to release only unmanaged resources.

GetCore()

Gets the core GStreamer element wrapper for advanced configuration and monitoring.

public BaseElement GetCore()

Returns

BaseElement

Always null for composite source blocks with multiple internal elements.

GetElement()

Gets the native GStreamer element for direct GStreamer pipeline integration.

public Element GetElement()

Returns

Element

The Spinnaker source GStreamer element.

IsAvailable()

Determines whether Spinnaker support is available on the current system. Requires Spinnaker SDK and GStreamer Spinnaker plugin to be installed.

public static bool IsAvailable()

Returns

bool

true if Spinnaker support is available; otherwise, false.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Sets the pipeline context for this Spinnaker source, providing access to the parent pipeline and logging context.

void IMediaBlockInternals.SetContext(MediaBlocksPipeline pipeline)

Parameters

pipeline MediaBlocksPipeline

The parent MediaBlocks pipeline containing this Spinnaker source.
