  • Creating farms of unique websites

    13 avril 2011, par

  • FFMPEG : Add a fixed size image on a video, regardless of the video width & height (resolution)

    11 mars 2017, par Drupalist

    This is my code that adds an image to videos, running via PHP :

    exec('ffmpeg -i input.mp4 -i logo.png -filter_complex 
    
"[0:v][1:v] overlay=10:10"  -pix_fmt yuv420p -c:a copy output.mp4');

    It works well but the problem is, the image is scaled down or up, up on the video resolution. For example in the following images the logo width is 50px but videos resolution are different :

    enter image description here

    and this one

    enter image description here

    How can I prevent the image from scaling down/up ?

    Update

    Thanks to Mulvya, he proposed these codes

    ffmpeg -i input.mp4 -i logo.png -filter_complex 
    
"[1:v][0:v]scale2ref=(W/H)*ih/8:ih/8[wm][base];[base][wm]overlay=10:10"
    
-pix_fmt yuv420p -c:a copy output.mp4

    and

    ffmpeg -i input.mp4 -i logo.png -filter_complex 
    
"[1:v][0:v]scale2ref=(W/H)*ih/8:ih/8[wm][base];[wm]setsar=1[wmsar];
    
[base][wmsar]overlay=10:10"
    
-pix_fmt yuv420p -c:a copy output.mp4

    that works very well, but it doesn’t keep the logo aspect ratio.
    I tried this code on two videos with different resolution and this is the result

    enter image description here

    and this one

    enter image description here

    Is it possible to improve this solution ?
