Constructor VideoWriter

public VideoWriter()

Creates video writer structure.

public VideoWriter(string fileName, FourCC fourcc, double fps, Size frameSize, bool isColor = true)

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: Frame rate 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).

Creates video writer structure.

public VideoWriter(string fileName, VideoCaptureAPIs apiPreference, FourCC fourcc, double fps, Size frameSize, bool isColor = true)

fileName string: Name of the output video file.
apiPreference VideoCaptureAPIs: allows to specify API backends to use. Can be used to enforce a specific reader implementation if multiple are available: e.g. cv::CAP_FFMPEG or cv::CAP_GSTREAMER.
