| Now that you have an RTMP streaming server in place and a way to send audio from local airwaves to it, the possibilities are endless. This configuration allows for multiple consumers at the same time, meaning you can have multiple endpoints all accessing the radio streams. The only limitation is the available processing power for the Raspberry Pi device to take on however many concurrent connections you want to throw at it! | Now that you have an RTMP streaming server in place and a way to send audio from local airwaves to it, the possibilities are endless.
