OBS is a free open source application that most Twitch and Youtube streamers use to do their thing. My web app is intended to function as a window capture outside of OBS. The user overlays the window capture over their streaming scene and matches chroma key colors between apps for a transparent background. Then they can activate games, tools, effects, and audio from Streamboy's control panel to enhance their streams.
The app utilizes a combination of CSS3 and jQuery for animation along with HTML5 audio for music and sounds. Javascript powers the control panel, games, and other tools. There's a scoreboard for fighting games, a giveaway screen to display game box art, and a screen that pulls Youtube embeds into the viewport — intending to eliminate the need to line up window captures every time the user wants to display a Youtube video on their stream.
I named the app Streamboy and added convenience features like hotkeys to make it easier to use. Shout-out to Luke VanTrieste for the original games, QA help, and some creative direction.
