Detailed Description

Attempting to implement the COM IMediaBuffer interface as a .NET object Not sure what will happen when I pass this to an unmanaged object.

Constructor & Destructor Documentation

◆ MediaBuffer()

NAudio.Dmo.MediaBuffer.MediaBuffer ( int maxLength )

inline

Creates a new Media Buffer.

Parameters

maxLength Maximum length in bytes

◆ ~MediaBuffer()

NAudio.Dmo.MediaBuffer.~MediaBuffer ( )

inlineprivate

Finalizer.

Here is the call graph for this function:

Member Function Documentation

◆ Dispose()

void NAudio.Dmo.MediaBuffer.Dispose ( )

inline

Releases the unmanaged resources used by the current instance of the ClassName class.

This method releases the unmanaged memory allocated for the buffer, if it is not already released. It also requests that the common language runtime not call the finalizer for the current instance of the class.

Here is the caller graph for this function:

◆ GetBufferAndLength()

int IMediaBuffer. NAudio.Dmo.MediaBuffer.GetBufferAndLength	(	IntPtr	bufferPointerPointer,
		IntPtr	validDataLengthPointer )

inlineprivate

Retrieves the buffer and its length and writes them to the specified memory locations.

Parameters

bufferPointerPointer	A pointer to the memory location where the buffer pointer will be written.
validDataLengthPointer	A pointer to the memory location where the valid data length will be written.

Returns: The result of the operation. Returns HResult.S_OK if successful.

If bufferPointerPointer is not IntPtr.Zero, the buffer pointer is written to the specified memory location. If validDataLengthPointer is not IntPtr.Zero, the valid data length is written to the specified memory location.

Implements NAudio.Dmo.IMediaBuffer.

◆ GetMaxLength()

int IMediaBuffer. NAudio.Dmo.MediaBuffer.GetMaxLength ( out int maxLength )

inlineprivate

Retrieves the maximum length of the media buffer and returns the result.

Parameters

maxLength When this method returns, contains the maximum length of the media buffer.

Returns: An HRESULT value indicating the success or failure of the method call.

Implements NAudio.Dmo.IMediaBuffer.

◆ LoadData()

void NAudio.Dmo.MediaBuffer.LoadData	(	byte[]	data,
		int	bytes )

inline

Loads the specified data into the buffer.

Parameters

data	The byte array containing the data to be loaded.
bytes	The number of bytes to be loaded from the data array.

This method sets the length of the buffer to the specified number of bytes and copies the data from the input data array into the buffer using the Marshal.Copy method.

Here is the caller graph for this function:

◆ RetrieveData()

void NAudio.Dmo.MediaBuffer.RetrieveData	(	byte[]	data,
		int	offset )

inline

Copies the elements of the buffer to the specified array starting at the specified offset.

Parameters

data	The destination array where the data will be copied.
offset	The zero-based byte offset in the destination array at which to begin copying bytes.

Exceptions

ArgumentNullException	Thrown when the destination array is null.
ArgumentOutOfRangeException	Thrown when the offset is less than zero or greater than the length of the destination array.

◆ SetLength()

int IMediaBuffer. NAudio.Dmo.MediaBuffer.SetLength ( int length )

inlineprivate

Sets the length of the media buffer.

Parameters

length The new length to be set for the media buffer.

Returns: HResult.E_INVALIDARG if the specified length is greater than the maximum length; otherwise, HResult.S_OK.

This method sets the length of the media buffer to the specified value. If the specified length is greater than the maximum length, it returns HResult.E_INVALIDARG; otherwise, it sets the length and returns HResult.S_OK.

Implements NAudio.Dmo.IMediaBuffer.
