  • Morphing images into each other using ffmpeg

    19 March 2023, by Christian

    I have a directory containing jpegs. Using ffmpeg I want to read the images and create a video out of it. The images should morph into each other, every image should be visible 2 seconds.

    


    So far, I came up with this:

    


    ffmpeg -i %d.jpg -c:v libx264 -pix_fmt yuv420p  ./bla.mp4


    


    Now what I'm missing is the morping part. I know there is a "morph" filter, however no matter how I try it, I either get an error that No such filter: 'morph' (even tho I compiled ffmpeg on own, making sure the needed libs are included) or I get a random 0xfff something error.

    


  • How to generate images from mp4 file?

    23 May 2013, by FlyingCat

    I am trying to generate the images from mp4 video file with ffmpeg.

    I only want the first 3 second of every video in the file.

    I have the following command..

     $videoFile = $mp4File; //I have many mp4 files
    

    
 $ffmpeg ="/usr/ffmpeg";
    

    
 $image_path = $videoFile;
    

    
 $ALL_PLACE_WIDTH = 300;
    
 $ALL_PLACE_HEIGHT = 220;
    

    
 $image_cmd = " -r 1 -r 0.03 -s ".$ALL_PLACE_WIDTH."x".$ALL_PLACE_HEIGHT." -f image2 ";
    
 $dest_path = 'project/image-%01d.png';
    

    
 $str_command= $ffmpeg  ." -i " . $image_path . $image_cmd .$dest_path;
    
 shell_exec($str_command);

    I am trying to generate firt 3 second image of every mp4 file but my script will genearte a lot of images and it create images across entire mp4 file.

    Can I restrict the script to get only the first 3 seconds images only? Thanks a lot!

  • FFMPEG Slideshow from set of videos and images

    14 September 2018, by Rahul

    I’m making a slideshow video from a couple videos and images.

    Making it from images only is quiet easy but what if I have to mix
    small videos too.

    In slideshow the next video/image should come when the previous video is fully played.

    Please suggest a command.
