In This Topic

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: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
