Custom Hardware Encoder

Hey guys,

I recently saw a company called Churchstreamer was able to provide a small dedicated hardware RTMP encoder which takes HDMI inputs and streams automatically to their streaming platform.

I was wondering if anybody knows how they managed to do this? I know that you can buy hardware encoders on the market, but it seems they have done it really cheaply and managed to put their own custom software onto the device.

How would they find a vendor who could make this for them?

Very impressive.
