Constructors

MediaBuffer(int)

Creates a new Media Buffer

public MediaBuffer(int maxLength)

Parameters

maxLength int

Maximum length in bytes

Properties

Length

Length of data in the media buffer

public int Length { get; set; }

Property Value

int

Methods

Dispose()

Dispose and free memory for buffer

public void Dispose()

Dispose(bool)

Releases the unmanaged CoTaskMem buffer. Called from both Dispose() and the finalizer; FreeCoTaskMem(nint) is safe to call from a finalizer thread.

protected virtual void Dispose(bool disposing)

Parameters

disposing bool

~MediaBuffer()

Finalizer — frees the unmanaged buffer if Dispose was not called.

protected ~MediaBuffer()

GetBufferAndLength(nint, nint)

public int GetBufferAndLength(nint bufferPointerPointer, nint validDataLengthPointer)

Parameters

bufferPointerPointer nint

Pointer to variable into which buffer pointer should be written

validDataLengthPointer nint

Pointer to variable into which valid data length should be written

Returns

int

HRESULT

GetMaxLength(out int)
