So with this command, we are able to center the Wolox logo within the beach image. W and H are the width and height of the beach and w/h the same for the overlay. (W-w)/2:(H-h)/2 If you read the official documentation of an overlay, it states that we can make a reference to the position of the input and the overlay with the capacity to change it.In this case, we want to overlay the input (the Wolox logo) over the input (The beach) Overlay Is the instruction for FFmpeg command to overlay 2 sources.Therefore, the beach would be 0 and the Wolox logo would be 1. To stay organized we can make a reference to every input by the order number of the input itself starting with 0.This is very useful when you are testing a command. -y Allows you to override the existing output.jpg file without any confirmation of the user.This command comes with new info (detailed below): String command = “ -i beach.jpg output.jpg“Īs you can see, with the overlay feature, we can add the wolox logo over the beach image, generating a new image (output.jpg).
All inputs will be defined by an argument -i. In FFmpeg, we are going to work with a variety of inputs- images, videos, GIFs, sounds, etc, and we are going to create a new output source with all our changes.
Therefore, I will disclose the most important arguments to create your app. It’s very important that you start creating a command from a basic line and then increase the complexity to accomplish what you want to do.įFmpeg-all is going to be, say our Bible of FFmpeg, however, it’s very difficult to read if you don’t know what you are you looking for.
#Os x ffmpeg rotate video software
It can also capture and encode in real-time from various hardware and software sources.” “ Ffmpeg: converts audio, image or video between different formats. The FFmpeg libraries have different types of tools (Ffmpeg, Ffserver, Ffplay, Ffprobe, etc), however, in this post, we are going to focus on the FFmpeg capabilities. With that, we are able to create the first FFmpeg command! Command- line Tools
