Spinnin' uses Sonata, so we added it as a bonus and a fullsetup in a demo project which you can use to test-drive

THE ROAD AHEADCurrent and future goals


MORE INPUTS

Mainly RTMP, as easy and functional as possible

Ideas are going around to combine graphic layers to a single video stream output


MORE CHANNELS

YouTube Live streaming is high on the priority list.


MORE QUALITY

Firmly tested code, good documentation and easier implementation.


IN CONCLUSIONLive broadcasting on a professional level is hard

Bandwidth may be your enemy on remote locations

Broadcasting consists of input, processing and outputTwitch and Facebook are already there, with Youtube soon to follow

More inputs will be added shortly

Spinnin' Records invested time and resources to give thisaway for free, when fixing or adding stuff a PR is much appreciated
