Class NVVideoConverterBlock

Namespace
VisioForge.Core.MediaBlocks.Nvidia
Assembly
VisioForge.Core.dll

NVIDIA video converter block for GPU-accelerated format conversion and color space transformation. This block performs high-performance video format conversions entirely on NVIDIA GPU hardware, supporting various pixel formats (YUV, RGB, NV12, etc.) and color space transformations. Leverages CUDA cores for parallel processing, achieving real-time conversion speeds even for high-resolution video. Essential for GPU-accelerated pipelines where format compatibility is required between different processing stages. Minimizes CPU usage and memory bandwidth by keeping data on the GPU throughout the conversion process. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

Methods

Build()

Constructs and initializes the NVIDIA video converter element within the pipeline. This method creates the GPU converter element, establishes input and output pads, and prepares the block for high-performance format conversion on NVIDIA hardware.

public override bool Build()

Returns

bool

true if the converter was successfully built and configured; false if initialization failed.

CleanUp()

Releases all resources and performs cleanup operations for this NVIDIA video converter block. This method disposes of the GPU converter element and resets the build state.

public void CleanUp()

Dispose(bool)

Releases unmanaged and - optionally - managed 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 BaseElement wrapper that provides additional functionality around the NVIDIA video converter element.

public BaseElement GetCore()

Returns

BaseElement

The BaseElement wrapper instance that encapsulates the GPU converter.

GetElement()

Gets the underlying GStreamer element that performs the GPU format conversion.

public Element GetElement()

Returns

Element

The GStreamer Element instance representing the NVIDIA video converter.

IsAvailable()

Determines whether this media block is available. Correct NuGet SDK redist should be included into your project. Checks for NVIDIA GPU hardware and required CUDA libraries.

public static bool IsAvailable()

Returns

bool

true if NVIDIA hardware acceleration is available; otherwise, false.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Associates this NVIDIA video converter block with a pipeline and initializes its internal context. This method is called internally when the block is added to a pipeline.

void IMediaBlockInternals.SetContext(MediaBlocksPipeline pipeline)

Parameters

pipeline MediaBlocksPipeline

The MediaBlocksPipeline instance that will manage this block.
