Live streaming with HTML5

This document contains collected notes regarding html5 live streaming approaches. I'm trying to understand how to build a system that enables streaming of live video to HTML5 clients. Following content is mainly centered around MPEG-DASH - modern way of dealing with given needs.

Approach 1

To prepare movie.avi from MPEG-DASH streaming we will execute following ffmpeg commands:

> ffmpeg -y -i movie.avi -an -c:v libx264 -x264opts 'keyint=24:min-keyint=24:no-scenecut' -b:v 1500k -maxrate 1500k -bufsize 3000k -vf "scale=-1:720" movie-720.mp4
> ffmpeg -y -i movie.avi -an -c:v libx264 -x264opts 'keyint=24:min-keyint=24:no-scenecut' -b:v 800k -maxrate 800k -bufsize 1600k -vf "scale=-1:540" movie-540.mp4
> ffmpeg -y -i movie.avi -an -c:v libx264 -x264opts 'keyint=24:min-keyint=24:no-scenecut' -b:v 400k -maxrate 400k -bufsize 800k -vf "scale=-1:360" movie-360.mp4
