I have a goal of building the worlds simplest screen recording software and I've been slowly noodling around on the project for the last couple of months (I mean really slowly).
In previous posts I had got the screen recording and a voice overlay by futzing about with the streams from all the input sources. One area of frustration though was that I could not work out how to get the audio from the desktop and overlay the audio from the speaker.
You should be able to create and edit videos using just the web in the browser. It should be possible to provide a user-interface akin to Screenflow that lets you create an output video that combines multiple videos, images, and audio into one video that can be uploaded to services like YouTube.
Following on from the my previous post that briefly describes the requirements of the video editor, in this post I just wanted to quickly show in a screencast how I built the web cam recorder, and also how how to build a screencast recorder :)

This post is really just a statement of intent. I am going to start the long process of working out what is and isn't available on the platform and seeing how far we can get today.
TL;DR - Here is a demo Code
Our team has built a lot of Progressive Web Apps recently to demonstrate how we think they can be built: Airhorner, Voice Memos, Guitar Tuner, SVG-OMG are a few that spring to mind. One thing that is common across all of these sites is that they have no server component to store and synchronise data. We built these sites as examples and reference implementations of the types of experiences that we can deliver on the web, they were never intended to be full "Apps" that you would build as a business.
