• How do I download the image with metadata in Python ? [closed]

  19 octobre 2024, par Temp Account

  I 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 !
