• ffmpeg - How to auto crop Harry Potter moving newspaper style video ?

  18 mai 2019, par hahahhhhhha

  The Harry Potter moving newspaper is like a video overlay on a static background. Here is an example youtube video :
  https://youtu.be/qQUUNmd3aco?t=1m17s the video starting from 1min, 17sec.

  HOWTO crop only the video part ? I have an image to show what i mean by the moving newspaper and what area does the video locate and what is the static background part. Please refer to the image. The area I draw by pink is where i mean by real video and any area except the video, is the static part.

  here is an illustration image :

  I understand if the frame size of the video does not change, I can specify the w, h, x, y to crop. But what if the frame size changes ? ie. w, h, x, y changes.(w, h : width, height of the video. x, y： Coordinate system starting point ) Is there a way to autodetect the static part and only crop the real video part ? like ffmpeg cropdetect for letterboxing. I tried cropdetect but failed. Any suggestion is welcome and I prefer using ffmpeg but any other softwares are welcome !
