Class GLUploadBlock

Namespace
VisioForge.Core.MediaBlocks.OpenGL
Assembly
VisioForge.Core.dll

OpenGL-accelerated video data upload block for transferring video frames from system memory to GPU memory. Provides high-performance video frame upload operations that transfer video data from CPU memory to OpenGL textures on the GPU, enabling GPU-accelerated video processing, effects, and transformations within the OpenGL pipeline. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

GLUploadBlock()

Initializes a new instance of the VisioForge.Core.MediaBlocks.OpenGL.GLUploadBlock class for GPU memory upload operations. Creates the necessary input and output pads for transferring video frames from system memory to GPU memory.

public GLUploadBlock()

Properties

Input

Gets the primary input pad for receiving video frames from system memory.

public override MediaBlockPad Input { get; }

Property Value

MediaBlockPad

Inputs

Gets all input pads available on this block (single input for video processing).

public override MediaBlockPad[] Inputs { get; }

Property Value

MediaBlockPad[]

Output

Gets the primary output pad for providing video frames in GPU memory.

public override MediaBlockPad Output { get; }

Property Value

MediaBlockPad

Outputs

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

public override MediaBlockPad[] Outputs { get; }

Property Value

MediaBlockPad[]

Type

Gets the media block type identifier for OpenGL upload operations.

public override MediaBlockType Type { get; }

Property Value

MediaBlockType

Methods

Build()

Builds and initializes the OpenGL upload block within the pipeline context. Creates the GStreamer upload element and establishes the necessary pad connections for transferring video frames from system memory to GPU memory.

public override bool Build()

Returns

bool

true if the upload block was successfully built and configured; otherwise, false.

CleanUp()

Cleans up all resources associated with the OpenGL upload operations, including GStreamer elements and GPU memory allocations.

public void CleanUp()

Dispose(bool)

Releases unmanaged and managed resources used by the OpenGL upload block. Properly disposes of GStreamer elements and GPU memory transfer 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

The BaseElement wrapper providing access to the underlying GStreamer upload element.

GetElement()

Gets the native GStreamer element for direct GStreamer pipeline integration.

public Element GetElement()

Returns

Element

The native Gst.Element representing the OpenGL upload filter.

IsAvailable()

Determines whether OpenGL upload functionality is available on the current system. Requires OpenGL support and appropriate GStreamer OpenGL memory transfer plugins to be installed.

public static bool IsAvailable()

Returns

bool

true if upload operations are supported; otherwise, false.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Sets the pipeline context for this OpenGL upload block, providing access to the parent pipeline and logging context.

void IMediaBlockInternals.SetContext(MediaBlocksPipeline pipeline)

Parameters

pipeline MediaBlocksPipeline

The parent MediaBlocks pipeline containing this upload block.
