We would know far more details to even know how to solve this.
But as generic hints, FFmpeg supports some udp protocol I believe and you should be able to use this via a URL in the style of ffmpeg://udp:// in MPlayer.
If this is a completely custom protocol and you already wrote a program to receive the data, you can also create a fifo and have your program write the receive data into it, while making MPlayer read from the other end. Or even just use pipe with MPlayer reading from stdin.
There are loads of other options, including implementing support for your protocol in MPlayer or FFmpeg directly, but that is a bit more advanced.
Or if you don't care about the protocol you could just use rtsp to send the data.
