Hi folks today in this video I will be talking about how to make a desktop app in which we will be removing audio from video using ffmpeg library. We will be using electron and node.js to make this application.
So you can see that this is the exact desktop app we will be building in this tutorial. In this app as you can see we have two buttons the first button is the select video button in which we can select the video to be processed and the second button is used to process the video and remove the audio from the video.

You can also put them in separate files and import them here. |
