Export frames/images from compressed video

I have a compressed movie (mp4) and I want to extract every single frame / image from it. I know that each individual frame of the video only contains the changed pixels regarding to the last keyframe, because of the video compression. But that is exactly what I want. I just want to see those differences. I want to visualy see how the compressor works.

Is there some tool like imagemagick out there what can things like that?

found a solution by my own using ffmpeg:

ffmpeg -i video.mp4 -f image2 -vf "select=eq(pict_type\,PICT_TYPE_P)" -vsync vfr pframe_%04d.png
