Following on from my previous post, so what if I now want to make a nice client side, but web-based application for playing videos. We can avoid using HTML for this purpose because we don’t need any search engine indexing, this means we get to use HTML5 canvas’s and a UI framework to speed up development.

Zebkit happens to be my favourite Javascript Canvas UI framework, it’s pretty quick to develop with and has most of the features of a standard desktop UI framework. What I found though is the video streaming is a bit lackluster, sure the support is technically in there but it made me long for the wonderful on-screen controls of the HTML5 video tag.

Recently I’ve wanted to look into how video streaming of local content can be done with NodeJS and HTML5’s video tag. I’ve only found one example to base upon, here. This demo though didn’t really cut it for me, for one it grabbed the file and split it in the client Javascript and then appended it to the video. Ideally, this would be done server side. It also has another bug where the split file doesn’t append at a time offset, and overwrites the original buffer.

I’ve created a demo that addresses these issues by creating a server in NodeJS that scans a videos directory and transcodes and splits the videos on the fly with ffmpeg. And uses mse_webm_remuxer to fix the format of these files in some magical way to make them compatible with HTML5’s MediaSource.
