ffmpeg - How do I render a video from a list of time-stamped images? -


I have the pattern & lt; Timestamp & gt; After .png is a directory full of images, where & lt; Timestamp & gt; represents milliseconds since the first image input.txt contains a list of interesting images:

  File '0.png' file ' 97 .png 'file' 178.png 'file' 242 I am using ffmpeg to add these images to a video:  
    Ffmpeg -r 15 -f concat -i input.txt output.webm  

How do I tell to move each frame in my actual position instead of time rather than using a framerate?
