Méthodes publiques

Méthode	Description
FourCC ( char c1, char c2, char c3, char c4 ) : int	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 ( string code ) : int	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.
IsOpened ( ) : bool	Returns true if video writer has been successfully initialized.
Open ( string fileName, FourCC fourcc, double fps, Size frameSize, bool isColor = true ) : void	Creates video writer structure.
Open ( string fileName, int fourcc, double fps, Size frameSize, bool isColor = true ) : void	Creates video writer structure.
Open ( string fileName, string fourcc, double fps, Size frameSize, bool isColor = true ) : void	Creates video writer structure.
Release ( ) : void
VideoWriter ( ) : System
VideoWriter ( string fileName, FourCC fourcc, double fps, Size frameSize, bool isColor = true ) : System	Creates video writer structure.
VideoWriter ( string fileName, int fourcc, double fps, Size frameSize, bool isColor = true ) : System	Creates video writer structure.
VideoWriter ( string fileName, string fourcc, double fps, Size frameSize, bool isColor = true ) : System	Creates video writer structure.

Méthodes protégées

Méthode	Description
Dispose ( bool disposing ) : void	Clean up any resources being used.

Private Methods

Méthode	Description
VideoWriter ( IntPtr ptr ) : System	Initializes from native pointer

Method Details

Dispose() protected méthode

Clean up any resources being used.

protected Dispose ( bool disposing ) : void
disposing	bool	/// If disposing equals true, the method has been called directly or indirectly by a user's code. Managed and unmanaged resources can be disposed. /// If false, the method has been called by the runtime from inside the finalizer and you should not reference other objects. Only unmanaged resources can be disposed. ///
Résultat	void

FourCC() public static méthode

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.

public static FourCC ( char c1, char c2, char c3, char c4 ) : int
c1	char
c2	char
c3	char
c4	char
Résultat	int

FourCC() public static méthode

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.

public static FourCC ( string code ) : int
code	string
Résultat	int

IsOpened() public méthode

Returns true if video writer has been successfully initialized.

public IsOpened ( ) : bool
Résultat	bool

Open() public méthode

Creates video writer structure.

public Open ( string fileName, FourCC fourcc, double fps, Size frameSize, bool isColor = true ) : void
fileName	string	Name of the output video file.
fourcc	FourCC	4-character code of codec used to compress the frames. For example, "PIM1" is MPEG-1 codec, "MJPG" is motion-jpeg codec etc. /// Under Win32 it is possible to pass null in order to choose compression method and additional compression parameters from dialog.
fps	double	Framerate of the created video stream.
frameSize	Size	Size of video frames.
isColor	bool	If it is true, the encoder will expect and encode color frames, otherwise it will work with grayscale frames (the flag is currently supported on Windows only).
Résultat	void
