I've also been using intra-refresh to stream h264 video. The encoder expects NAL units and, after encoding, the data is streamed in packets. Your frame may or may not fit your encoded frame into a single packet, depending on its size. At the receiving end, you should wait until you receive all the data corresponding to a frame which you can then send to your decoder.
I use x264 to do the encoding, live555 to do the streaming and ffmpeg to do the decoding. There are a lot of examples in the live555 codebase so you shouldn't have a problem in seeing an example of what you are intending to do.
Hope this helps,
