Open Broadcaster Software is free and open source software for the purposes of streaming live media content to the internet or to video files. Originally I made Open Broadcaster Software for myself because I thought "why should I pay a subscription for software I could probably write?" And so, I did and Open Broadcaster Software evolved into somewhat of a monster of a project. That's pretty much the Open Broadcaster Software story.
I hope people can make use of Open Broadcaster or learn something from it. I know I'm having a ton of fun writing Open Broadcaster and am learning much in the process. Overall it's been an excellent experience.
