Class TSAnalyzerBlock

Namespace

VisioForge.Core.MediaBlocks.Special

Assembly

VisioForge.Core.dll

Analyzes an MPEG transport stream: parses PAT/PMT/PSI to enumerate programs and elementary streams, computes per-PID bitrate, detects continuity-counter errors and tracks PCR timing (intervals and discontinuities).

The block accepts a raw MPEG-TS byte stream (for example from BasicFileSourceBlock, UDPRAWSourceBlock or SRTRAWSourceBlock). In VisioForge.Core.Types.X.Special.TSAnalyzerMode.InputOutput mode the stream is forwarded unchanged to the output pad for inline monitoring; in VisioForge.Core.Types.X.Special.TSAnalyzerMode.Input mode the block is terminal.

Subscribe to VisioForge.Core.MediaBlocks.Special.TSAnalyzerBlock.OnAnalysisUpdated for periodic snapshots, or call VisioForge.Core.MediaBlocks.Special.TSAnalyzerBlock.GetReport for the current state.

Implements the VisioForge.Core.MediaBlocks.MediaBlock. Implements the VisioForge.Core.MediaBlocks.IMediaBlockInternals.

Constructors

TSAnalyzerBlock(TSAnalyzerMode, TSAnalyzerSettings)

Initializes a new instance of the VisioForge.Core.MediaBlocks.Special.TSAnalyzerBlock class.

public TSAnalyzerBlock(TSAnalyzerMode mode = TSAnalyzerMode.Input, TSAnalyzerSettings settings = null)

Parameters

mode TSAnalyzerMode

The operating mode. Defaults to VisioForge.Core.Types.X.Special.TSAnalyzerMode.Input.

settings TSAnalyzerSettings

Optional analyzer settings.

Properties

Input

Gets the input pad receiving the MPEG-TS byte stream.

public override MediaBlockPad Input { get; }

Property Value

MediaBlockPad

Inputs

Gets the array of input pads (a single auto-typed input).

public override MediaBlockPad[] Inputs { get; }

Property Value

MediaBlockPad[]

Mode

Gets the operating mode.

public TSAnalyzerMode Mode { get; }

Property Value

TSAnalyzerMode

Output

Gets the passthrough output pad, or null in VisioForge.Core.Types.X.Special.TSAnalyzerMode.Input mode.

public override MediaBlockPad Output { get; }

Property Value

MediaBlockPad

Outputs

Gets the array of output pads (one in passthrough mode, empty otherwise).

public override MediaBlockPad[] Outputs { get; }

Property Value

MediaBlockPad[]

Type

Gets the media block type identifier for this block.

public override MediaBlockType Type { get; }

Property Value

MediaBlockType

Methods

Build()

Builds the block within the pipeline.

public override bool Build()

Returns

bool

true on success.

CallAnalysisUpdated(TSAnalyzerEventArgs)

Raises the VisioForge.Core.MediaBlocks.Special.TSAnalyzerBlock.OnAnalysisUpdated event.

public void CallAnalysisUpdated(TSAnalyzerEventArgs args)

Parameters

args TSAnalyzerEventArgs

The event data.

CleanUp()

Performs cleanup of internal resources.

public void CleanUp()

Dispose(bool)

Releases unmanaged and - optionally - managed resources.

protected override void Dispose(bool disposing)

Parameters

disposing bool

true to release managed resources.

GetCore()

Gets the core GStreamer element wrapper.

public BaseElement GetCore()

Returns

BaseElement

The wrapper.

GetElement()

Gets the underlying GStreamer element.

public Element GetElement()

Returns

Element

The element.

GetReport()

Gets the current analysis report.

public TSAnalyzerReport GetReport()

Returns

TSAnalyzerReport

The report, or null if the block has not been built.

IsAvailable()

Determines whether the analyzer is available in the current environment.

public static bool IsAvailable()

Returns

bool

true if available.

IMediaBlockInternals.SetContext(MediaBlocksPipeline)

Associates this MediaBlock with a pipeline and initializes its internal context. This method is called automatically when the block is added to a pipeline, providing access to shared resources and pipeline-wide configuration.

void IMediaBlockInternals.SetContext(MediaBlocksPipeline pipeline)

Parameters

pipeline MediaBlocksPipeline

The MediaBlocksPipeline instance that will manage this block.

OnAnalysisUpdated

Occurs when a new analysis snapshot is available. Raised periodically (per VisioForge.Core.Types.X.Special.TSAnalyzerSettings.StatisticsInterval) and once more at end-of-stream (with VisioForge.Core.Types.X.TSAnalyzerEventArgs.IsFinal set). Periodic snapshots are raised on a background timer thread; the final (VisioForge.Core.Types.X.TSAnalyzerEventArgs.IsFinal) report is raised synchronously on the GStreamer streaming thread at end-of-stream. In both cases marshal to the UI thread as needed and keep handlers non-blocking.

public event EventHandler<TSAnalyzerEventArgs> OnAnalysisUpdated

Event Type

EventHandler<TSAnalyzerEventArgs>
