  I am trying to overlay gif on Image and save it as Video. And use ffmpeg to do this but getting this error :

  Command

  String strFilter = "[1:v]scale=h="+ 150 +":w=" + 150 + "[overlay_scaled],"
  
                          + "[0:v][overlay_scaled]overlay=eval=init:x=W*" + 0
  
                          + ":y=H*" + 0;
  
  
  
  String[] bb = new String[]{ "-i", inputFile,"-itsoffset", "0", "-i", inputGif, "-filter_complex", strFilter, "-preset", "ultrafast", "-g", "120", outputFile };

  Here

  • inputFile is png image
  • inputGif is gif image
  • outputFile is mp4 Video

  it give me an errors like this :

  Unable to probe /var/www/html/dev/laravel/storage/app/https://dev.cilsy.id/assets/source/lessons/video-4/1. Introduction (1).mp4

  so the problem is it the way I check that it has multiple file using is_array is right ? and the second what can cause this problems ?

• Using FFMPEG library with iPhone SDK for video encoding

  7 août 2020, par user203349

  I need to encode several pictures shot by the iPhone camera into a mp4 video file and I know FFMPEG can do this (the application TimeLapser and ReelMoments do it already). I plan to use this in my app iMotion (available in the appstore).

  


  I successfully install and compile the ffmpeg for the iphone SDK with this link :
http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2009-October/076618.html

  


  But now I'm stuck here in my XCode project. What should I do next to use the FFMPEG library for video encoding ? The Apple documentation about external library using is very light and I just can find any tutorial on the web which explains how to do this.
