FFmpeg.wasm, a pure WebAssembly / Javascript port of FFmpeg

FFmpeg is a famous framework/tool when it comes to video/audio processing, now with ffmpeg.wasm you can use FFmpeg right inside your browser without installation or upload your file to the server. Although ffmpeg.wasm is not as fast as FFmpeg, but it might come in handy for certain use cases.

In this post, I would like to share how to install and use ffmpeg.wasm and also technical details behind to support your usage.

Install ffmpeg.wasm

To install and use ffmpeg.wasm, you only need to use npm/yarn:

$ npm install @ffmepg/ffmpeg
## or
$ yarn add @ffmpeg/ffmpeg

To use ffmpeg.wasm in node environment, you also need to install @ffmpeg/core .

$ npm install @ffmepg/core
## or
$ yarn add @ffmpeg/core

Or you can use a CDN

<script src='https://unpkg.com/@ffmpeg/ffmpeg@0.9.3/dist/ffmpeg.min.js'></script>

Running Go in the Browser with WASM and Web Workers

We’ve recently made big changes to how we execute Go in the browser on Qvault and want to explain the enhancements. Web Workers are the reason we’ve been able to solve some of the serious browser-related coding problems that were holding us back. Consider this article a sequel to Running Go in the Browser with Web Assembly.

While publishing our latest course, Big-O Algorithms, we needed a way to print console output while code is still executing. We ran into a problem when running computationally expensive algorithms in the browser; the browser gets so bogged down that it can’t render new lines of output. We decided to implement web workers, and they solved the problem handily.

The Problem

In the old Qvault, console output was all printed at once. The program executed, then the output was displayed. We found this to be less than ideal because it is often useful to see when something prints, especially when trying to optimize an algorithm for speed.

For example, this code used to print all of its output at once:

package main

import (
	"fmt"
)

func main(){
	const max = 100000000
	for i := 0; i < max; i++{
		if i % (max/10) == 0{
			fmt.Println(i)
		}
	}
}

Since adding Web Workers, now it appropriately prints each number at the time of execution. You can see for yourself on the playground here.

What Is a Web Worker?

Web Workers are a simple means for web content to run scripts in background threads.

Mozilla

In other words, its a way for us to finally break free from the single-threaded clutches of JavaScript! We can offload expensive tasks to another thread of execution. Doing this leaves the browser free to render updates on the screen.

Wrapping JavaScript libraries in Blazor WebAssembly/WASM

Blazor WebAssembly is one of the newest front-end frameworks on the block. It enables you to write frontend in C## and makes it possible to use many of the .NET libraries that you already know. Most websites use some JavaScript libraries that make it easier to make complex animations, self-aligning components, or other dynamic interactions. People are already working on making libraries that make it easy to add complex features to your website using Blazor as well. But for now, you might still be missing a way to do that one thing that some JavaScript library does when working with Blazor. You could reimplement that feature in Blazor WebAssembly from the ground up, but that might be a lot of work. In this article, we will show how you can wrap a JavaScript library in Blazor and thereby getting that one feature into Blazor WebAssembly.

What is JavaScript - Stackfindover - Blog

Who invented JavaScript, how it works, as we have given information about Programming language in our previous article ( What is PHP ), but today we will talk about what is JavaScript, why JavaScript is used The Answers to all such questions and much other information about JavaScript, you are going to get here today. Hope this information will work for you.

Who invented JavaScript?

JavaScript language was invented by Brendan Eich in 1995. JavaScript is inspired by Java Programming Language. The first name of JavaScript was Mocha which was named by Marc Andreessen, Marc Andreessen is the founder of Netscape and in the same year Mocha was renamed LiveScript, and later in December 1995, it was renamed JavaScript which is still in trend.

What is JavaScript?

JavaScript is a client-side scripting language used with HTML (Hypertext Markup Language). JavaScript is an Interpreted / Oriented language called JS in programming language JavaScript code can be run on any normal web browser. To run the code of JavaScript, we have to enable JavaScript of Web Browser. But some web browsers already have JavaScript enabled.

Today almost all websites are using it as web technology, mind is that there is maximum scope in JavaScript in the coming time, so if you want to become a programmer, then you can be very beneficial to learn JavaScript.

JavaScript Hello World Program

In JavaScript, ‘document.write‘ is used to represent a string on a browser.

<script type="text/javascript">
	document.write("Hello World!");
</script>

How to comment JavaScript code?

  • For single line comment in JavaScript we have to use // (double slashes)
  • For multiple line comments we have to use / * – – * /
<script type="text/javascript">

//single line comment

/* document.write("Hello"); */

</script>
