Methods

	Name	Description
	AllocGCHandle	Pins the object to be allocated by cvSetData. (Inherited from DisposableObject.)
	AllocMemory	Allocates the specified size of memory. (Inherited from DisposableObject.)
	Dispose	Releases the resources (Inherited from DisposableObject.)
	DisposeManaged	Releases managed resources (Inherited from DisposableObject.)
	DisposeUnmanaged	Releases unmanaged resources (Overrides DisposableCvObjectDisposeUnmanaged.)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Destructor (Inherited from DisposableObject.)
	FourCC(String)	Concatenates 4 chars to a fourcc code. This static method constructs the fourcc code of the codec to be used in the constructor VideoWriter::VideoWriter or VideoWriter::open.
	FourCC(Char, Char, Char, Char)	Concatenates 4 chars to a fourcc code. This static method constructs the fourcc code of the codec to be used in the constructor VideoWriter::VideoWriter or VideoWriter::open.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsOpened	Returns true if video writer has been successfully initialized.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	NotifyMemoryPressure	Notifies the allocated size of memory. (Inherited from DisposableObject.)
	Open(String, FourCC, Double, Size, Boolean)	Creates video writer structure.
	Open(String, Int32, Double, Size, Boolean)	Creates video writer structure.
	Open(String, String, Double, Size, Boolean)	Creates video writer structure.
	Release
	ThrowIfDisposed	If this object is disposed, then ObjectDisposedException is thrown. (Inherited from DisposableObject.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Write	Writes/appends one frame to video file.
