How to get perspective coordinates from file for image overlay with ffmpeg?
<p>Is it possible to do something like <a href="https://www.youtube.com/watch?v=APxgPYZOd0I" rel="nofollow">this</a> purely with ffmpeg?</p>

<p>Lets say we have a text file with the frame by frame coordinates for the 4 corners where the image should go. ffmpeg has a <a href="https://ffmpeg.org/ffmpeg-filters.html" rel="nofollow">perspective filter</a>, but how would one get ffmpeg to pull the frame coordinates from the text file? I'm guessing with a pipe of sorts?</p>
