  • recording video in real-time with OpevCV VideoWriter

    19 février 2016, par nick topper

    I have a few OpenCV projects that analyze video over USB, and in certain conditions must record the video stream to a file. People using my software complain that 10+ minute recordings yield video files that are about 20 seconds longer than they should be.

    I’m using openCV’s VideoWriter. Iv’e tried things like setting CV2_CAP_PROP_FPS to a very low setting, and iv’e tried getting the average frame rate over a few seconds to find a good setting for my frame rate of the output file. Still not close enough to real time for my needs.

    Does anyone know of a good way to make sure my video is recording close to real time ? Should I use something like time.sleep (in python) to cap my framerate ? Or is there a better way to do this ?

    Video compressing successfully, but it taking more than 150 seconds. I am unable find out how to reduce that time.

    I want to change this command to complete this process in less time.
