How do I download the image with metadata in Python ? [closed]
19 octobre 2024, par Temp AccountI am downloading some images in Python from the Airtable API and am trying to make a slideshow with them using ffmpeg. I download the images :


urllib2.urlretrieve(img['url'], "output/images/image_"+str(i)+".jpeg")


However, when I run the following ffmpeg command


ffmpeg -framerate 4/60 -i output/images/image_%d.jpeg output/out.mp4


I get the following error :

However, downloading the images in Chrome then creating the slideshow is successful. The images from Chrome have metadata of the filetype (JPEG), width and height. The images downloaded with Python have no metadata. How do I download that information so that my ffmpeg command will succeed ?


Thanks !

MoviePy error : failed to read the first frame of video file ****. That might mean that the file is corrupted
14 juillet 2022, par Udit Hari VashishtI am trying to reverse a video using MoviePy. My code is as under : -

I have tried the code on both Mac and Windows PC. The other functionality of MoviePy works fine, but I am not able to reverse the video. Both of my systems have ImageMagick and FFMPEG installed.
