I've seen the type of errors you mentioned. I believe this has something to do with lack of codec-container support in OpenCV. Try changing your output video filename to end in ".avi". See further discussion in the thread Videowriter recording MP4 + X264 (OpenCV 3.1).
OpenCV: FFMPEG: tag 0x34363258/'X264' is not supported with codec id 28 and format 'mp4 / MP4 (MPEG-4 Part 14)' OpenCV: FFMPEG: fallback to use tag 0x00000021/'!???'

I am leaning towards the optical flow calculation, but you should add duration calculations to various operations to narrow down what operations are taking more time.
