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

Syntax

public abstract System.bool CheckStart( 
   System.IO.Stream stream,
   System.string TransferSyntax
)

public function CheckStart( 
    stream: System.IO.Stream;
    TransferSyntax: System.String
): System.Boolean; abstract;

public __abstract function CheckStart( 
   stream : System.IO.Stream,
   TransferSyntax : System.String
) : System.boolean;

public: abstract System.bool CheckStart( 
   System.IO.Stream* stream,
   System.string* TransferSyntax
)

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

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

'Usage
 
Dim instance As CodecFactory
Dim stream As System.IO.Stream
Dim TransferSyntax As System.String
Dim value As System.Boolean
 
value = instance.CheckStart(stream, 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 4.8 or higher
