Remarks

On Windows, a destination path containing characters that can't be represented in the process's ANSI code page may fail to open even though the parent directory exists. Unlike VideoCapture, there is no stream-based constructor to work around this (the underlying cv::VideoWriter has no custom-stream write API); write to an ASCII-safe path instead.

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.

Get(VideoWriterProperties)

Returns the specified VideoWriter property

GetBackendName()

Returns used backend API name. Note that stream should be opened.

IsOpened()

Returns true if video writer has been successfully initialized.
