# Release all space and windows once done Name = './data/frame' + str(currentframe) + '.jpg' # if video is still left continue creating images Print ('Error: Creating directory of data') How to avoid them?Ĭam = cv2.VideoCapture("C:\\Users\\zoomrx\\Desktop\\Video\\1.mp4") I want to extract only the slides from the video.ĮDIT: Able to extract the slides, now there are lot of redundant frames being captured, example in the image. There may be some mileage in this as a solution, but feels very inefficient so would rather avoid if possible.I have multiple conference video (.mp4) wherein the speakers are presenting a slide show and slides are changing randomly (depending on how much speaker wants to comment on it). Try to 'repair' the videos before processing.also not sure which codec OpenCV is using (I know it's definitely not FFMPEG, so there's more than one codec not happy with these headers!)
I have asked Reolink, the manufacturer, if they can shed any light. Fix the videos so they're not corrupt.I've put one of the videos on Dropbox so you can see: Īnyone have any ideas what's causing this, or how to fix it? I think I've got a few options, but don't have enough info to progress any of them: Worryingly, around 1 in 4 of the videos saved via FTP give this error in my Python app, and if I try to load them via FFMPEG on either my server or on my (Mac) laptop, I get the error error reading header : Operation not permitted Since getting a new server and reinstalling all of the software, which happens to mean updated versions of Debian Linux, Python and OpenCV, it no longer tolerates the errors and fails to load those videos. It's been working fine for the past year or so, although I often noticed warnings in the Python console (from OpenCV) about "error reading header", but it worked anyway so ignored it. I've then got my own Python-based application processing those videos. I've got a Reolink security camera, which saved.
