Running Environment: Win7 OpenCV1.0 VC6.0. The following video generation Code uses the XVID encoder. If no download is required on the computer, otherwise the size of the generated video file is 0. Or you can set cvCreateVideoWriter ("out. avi ", CV_FOURCC ('x', 'V', 'I', 'D'), fps, cvSize (frameW, frameH), isColor) 'x ', 'V', 'I', and 'D' can be changed to an existing encoder on the computer.

 

Note: multiple images are merged into videos, so the last generated video has no sound.
