Ffmpeg: move the "image" slider over the "background" from 0% to 100% in sync with audio

I am trying to create a video using the following code:

`$`ffmpeg -loop 1 -r 5 -i video.png -r 5 -i progress.png -filter_complex "overlay=x='if(gte(t,0), -W+(t)*5, NAN)':y=H-h" -i video.mp3 -acodec copy video.mp4

I have the following files

  • video.png http://i.imgur.com/pmwnaLV.png
    • This is a still frame of 1280x720 pixels, which is just a background with the waveform of the video.mp3 file.
  • progress.png http://i.imgur.com/qXltKR2.png
    • it's just a translucent image of 1280x100 pixels that should simulate the animation (from 0 to 100% of the width of the video.png file to simulate the animation "fill up".

My problems are as follows:

  • Video does not sync with audio. The progress indicator fails, and does not end at the end of the song, it just continues and continues on ...
  • Also ... it just goes on and on! I left him making the video in 1 hour, and he never stopped.
