Comment (by Michael Koch):

 Use this command for extracting JPG images from the video:
 ffmpeg -i burger.mp4 -vf framestep=10 burger%%3d.jpg

 Make this batch file and save it on the desktop:
 ffplay -loop 0 -t 0 -x 500 -an %1
 pause

 Drag and drop the first extracted image on the icon of the batch file.
 Drag and drop the video on the icon of the batch file. It will show only
 the first frame of the video.

 Now you see both frames side by side (with the same player) and there
 should be no difference.
