    13 avril 2011, par

  • Green overlay with multiply blend mode using FFMPEG

    25 mars 2014, par Barto

    I'm currently working on a project which needs video editing.
    Here for I'm using ffmpeg, which is working pretty well, except for 1 filter.
    Every video should get an overlay with the Photoshop multiply blend mode.
    I'm using the ffmpeg blend mode, but unfortunately the video gets a green overlay as you can see in the screenshots.

    Does this has something to do with the mode I'm working in ?
    Below is my current code

    #!/bin/bash
    
vagrant ssh -c "./ffmpeg \
    
-i /vagrant/public/uploads/video/bw_RzWecVH02p.avi -i /vagrant/public/img/red_ellipse.png \
    
-filter_complex "blend=all_mode='multiply'" \
    
/vagrant/public/uploads/video/overlay_RzWecVH02p.mp4"

    Here is my ffmpeg output

  • FFMPEG incorrect image extension fails coding [closed]

    14 novembre 2016, par G.T.

    I have a problem using ffmpeg on images. My problem is that quite a lot of images on the internet has incorrect extension ( png files names .jpg and jpg files named .png) which makes the ffmpeg fail.

    I couldn’t find any documentation on the internet how can this be fixed ? Can I force somehow ffmpeg to try to look in other codec types too not just the ones the extension suggests ?

    To reproduce this you just need to download a png from the internet and rename it’s extension to .jpg

    And even if you use the simplest command like ffmpeg -i image.jpg it fails with :
