| filename | String | Name of the output video file. |
| fourcc | int | 4-character code of codec used to compress the frames. For example, CV_FOURCC('P','I','M','1') is MPEG-1 codec, CV_FOURCC('M','J','P','G') is motion-jpeg codec etc. |
| fps | double | Framerate of the created video stream. |
| frameSize | System | 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 |
