  • FFMPEG command for video based on ratio

    15 mars 2017, par pocek

    I am using ffmpeg (in linux server with php)

    and i want to watermark a png logo on the mp4 file, my problem is that

    I want to scale my logo and change it based on source video size(for example 1/4 of height),

    I have this code bellow :

    shell_exec('ffmpeg -i file.mp4 -i logo.png -filter_complex "overlay=10:10" file-watered.mp4");

    it works on every video.

    For Normal (medium) size image :

    enter image description here

    For Small (medium) size image (witch is bad !)

    enter image description here

    Ideal output for this size would be :

    enter image description here

    I’ve changed a little bit my first code like this :

    shell_exec('ffmpeg -i file.mp4 -i logo.png -filter_complex "[0:v]scale=500:-1[bg];[bg][1:v]overlay=(main_w-overlay_w):(main_h-overlay_h)" watered.mp4');

    The main problem is that, I want to change the logo size based on video size.

    How can i do it with ffmpeg ?
