CheckStart Method

In This Topic

Check whether a stream contains data which could be the start of a frame of compressed data

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public MustOverride Function CheckStart( _
   ByVal stream As Stream, _
   ByVal TransferSyntax As String _
) As Boolean

'Usage
 
Dim instance As CodecFactory
Dim stream As Stream
Dim TransferSyntax As String
Dim value As Boolean
 
value = instance.CheckStart(stream, TransferSyntax)

public abstract bool CheckStart( 
   Stream stream,
   string TransferSyntax
)

public:
abstract bool CheckStart( 
   Stream^ stream,
   String^ TransferSyntax
)

Parameters

stream: The fragment data to test
TransferSyntax: The transfer syntax to check against

Return Value

true if the data could be the start of a new frame for this transfer syntax

Remarks

This routine is used in the difficult cases where the basic offset table is empty, and where there is no obvious 1:1 relationship between fragments and frames, to determine which fragment is the start of which frame.

Requirements

Target Platforms: .NET CLR 4.0 or higher
