  FFmpeg support for animation

  Posted by Md. faruk Hossain on February 5, 2014 at 3:45 am

  Dear All,

  I am a Android Developer. Recently I have a project to integrate ffmpeg in our Android project. But i face a problem to add different animation on different images such as: fade-in, fade-out, scale, rotate, translate etc android animation. These images will make a video. I successfully made video from images but didn’t add animation on images.

  Can you please suggest me how can i do this. Is there any command in ffmpeg to add animation on Images.

  I run this command on Linux platform:

  “ffmpeg -i input.mp4 “fade=in:5:8″ output.mp4”

  But the problem is that new new created video “output.mp4” just show a black screen no images.

  Thanks for your time

  BR,
  Faruk

  Please include the complete ffmpeg console output, and don’t forget the code button to format it.

  I think it should be
  ffmpeg -i input.mp4 -vf "fade=in:5:8" output.mp4

  Many ffmpeg filters can be animated programatically over time, for example rotate can be applied thus: rotate=2*PI*t to rotate the image once every second (t is a constant representing the current time in seconds)
