Class SRTSourceBlock

Namespace
VisioForge.Core.MediaBlocks.Sources
Assembly
VisioForge.Core.dll

SRT (Secure Reliable Transport) source block with integrated decoding capabilities for complete media playback. Provides secure, low-latency streaming reception with automatic video, audio, and subtitle decoding for live broadcasting, remote production, and professional streaming applications requiring high-quality, reliable transmission over unreliable networks. Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals. Implements the IDisposable.

SRTSourceBlock(SRTSourceSettings, bool, bool, bool)

Initializes a new instance of the VisioForge.Core.MediaBlocks.Sources.SRTSourceBlock class with custom SRT settings and stream selection. Configures the SRT source with integrated decoding for secure low-latency streaming with specified output streams.

public SRTSourceBlock(SRTSourceSettings settings, bool renderVideo = true, bool renderAudio = true, bool renderSubtitle = false)

Parameters

settings SRTSourceSettings

The SRT settings controlling URI, encryption, latency, bandwidth, and network configuration parameters.

renderVideo bool

If set to true, enables video stream decoding and output.

renderAudio bool

If set to true, enables audio stream decoding and output.

renderSubtitle bool

If set to true, enables subtitle stream decoding and output.

Properties

AudioOutput

Gets the audio output pad that provides decoded SRT audio stream to downstream blocks.

public MediaBlockPad AudioOutput { get; }

Property Value

MediaBlockPad

DisableAudioConverter

Gets or sets a value indicating whether to disable audio converter for direct audio output.

public bool DisableAudioConverter { get; set; }

Property Value

bool

Input

Gets the primary input pad (none for source blocks that receive network streams).

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 output pad (video output for SRT stream).

public override MediaBlockPad Output { get; }

Property Value

MediaBlockPad

Outputs

Gets all output pads available on this block (dynamic based on enabled streams).

public override MediaBlockPad[] Outputs { get; }

Property Value

MediaBlockPad[]

Settings

Gets or sets the SRT configuration settings that control network parameters and decoding options.

public SRTSourceSettings Settings { get; set; }

Property Value

SRTSourceSettings

SubtitleOutput

Gets the subtitle output pad that provides decoded SRT subtitle stream to downstream blocks.

public MediaBlockPad SubtitleOutput { get; }

Property Value

MediaBlockPad

Type

Gets the media block type identifier for SRT source operations with decoding.

public override MediaBlockType Type { get; }

Property Value

MediaBlockType

VideoOutput

Gets the video output pad that provides decoded SRT video stream to downstream blocks.

public MediaBlockPad VideoOutput { get; }

Property Value

MediaBlockPad

Methods

Build()

Builds and initializes the SRT source with decoding within the pipeline context. Establishes secure SRT connection, configures automatic decoding, and prepares decoded outputs for downstream processing.

public override bool Build()

Returns

bool

true if the SRT source with decoding was successfully built and configured; otherwise, false.

CleanUp()

Cleans up all resources associated with the SRT operations, including secure connection, decoders, and media buffers.

public void CleanUp()

Dispose(bool)

Releases unmanaged and managed resources used by the SRT source with decoding. Properly closes SRT connection and disposes of GStreamer elements, decoders, and streaming 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 DecodeBinElement wrapper element for advanced decoding configuration options.

GetElement()

Gets the native GStreamer element for direct GStreamer pipeline integration.

public Element GetElement()

Returns

Element

The decode bin GStreamer element.

IsAvailable()

Determines whether SRT support with decoding is available on the current system. Requires GStreamer SRT source plugins, decode bin, and SRT libraries to be installed and functional.

public static bool IsAvailable()

Returns

bool

true if SRT support with decoding is available; otherwise, false.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

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

void IMediaBlockInternals.SetContext(MediaBlocksPipeline pipeline)

Parameters

pipeline MediaBlocksPipeline

The parent MediaBlocks pipeline containing this SRT source.
