· I want to capture video from a webcam and save it to an mp4 file using opencv. I found example code on stackoverflow (below) that works great. The only hitch is that I'm trying to save it as mp4, not avi. Part of what I don't get is that the 'XVID' argument passed to the FOURCC writer is supposed to be, I think, an mp4 codec (from this link Reviews: 5. · Sample training dataset download link: traning_img.

So this was the tutorial of Face Recognition from video in python using OpenCV. I hope this will be helpful for you. Thank topfind247.cos: 1. · Object detection is a branch of Computer Vision, in which visually observable objects that are in images of videos can be detected, localized, and recognized by computers. An image is a single frame that captures a single-static instance of a naturally occurring event. On the other hand, a video contains many instances of static images.
OpenCV's CUDA python module is a lot of fun, but it's a work in progress. For starters, we have to load in the video on CPU before passing it (frame-by-frame) to GPU. topfind247.co() has not. The video might be slow and it is because the number of frames is usually large in OpenCV. However, if you save the video on your hard drive, the written video is not slow and matches the fps. I have a video file, I know how to save all of the frames,but my question is how to save only one frame of every 20 frames as an image? Thanks. python opencv video-processing opencv
