Ok, let’s start, firstly I will answer the question of What is FFmpeg, secondly, I will tell you how to get FFmpeg and I will give some examples about using FFmpeg.

Only browsers with SharedArrayBuffer support can use ffmpeg.wasm, you can check HERE for the complete list.Before answering the question of what is FFMpeg, let me tell you something interesting about FFmpeg.Īlmost everyone, who are developing video/audio software, knows FFmpeg deeply, but If they are not specifically in this industry, almost nobody knows What FFmpeg is. You do need to be aware of the need for SharedArrayBuffer support: Update 2022 - the following library is also worth looking at for browser side - I have used it and found it works well and the performance, leveraging web assembly language is noticeably better:

If you want to do it server side, in a Javascript based server like node for example, then again there are libraries available - e.g.: You would need to do some testing - video processing is very compute intensive and may not work well for you in the browser.
