+# Streaming protocol specification
+
+Server streams data to clients. There is only one server and there can be zero
+or more connected clients.
+
+## Messages from Server to Client (ClientBound)
+
+Each server streaming session must start with `ClientBound{start}` and
+stop with `ClientBound{stop}` messages. Interleaved  `ClientBound{video}`
+and `ClientBound{overlay}` are allowed in between:
+
+```
+-> ClientBound{start={width=<width>, height=<height>}}
+
+-> ClientBound{video} or ClientBound{overlay}
+
+-> ClientBound{stop}
+```
+
+Each video message contains one or more H264 encoded NAL units. Partial NAL
+units are not allowed. The first NAL unit must be SPS (Sequence Parameter Set),
+the second one is IDR. Concatenation of all video messages should produce a
+valid H264 bitstream. All subsequent SPS NAL units must contain the same
+information as the first one.
+
+Overlay messages are allowed at any time. You can think that there are two
+logical streams during the session: video stream and stream of overlays.
+Each overlay message contains SVG image which is drawn on top of the video.
+
+## Messages from Client to Server (ServerBound)
+
+Client can control the server by sending `ServerBound{stream_control}` messages.
+There are only two allowed: `ServerBound{stream_control={enabled=true}}` to
+start streaming and `ServerBound{stream_control={enabled=false}}` to stop
+streaming. Server could ignore these messages if it is already in the requested
+state.
+
+```
+<- ServerBound{stream_control={enabled=true}}
+
+
+<- ServerBound{stream_control={enabled=false}}
+
+```
+
+## Example
+
+From the Server's point of view ordered by absolute time:
+
+```
+<- ServerBound{stream_control={enabled=true}}
+-> ClientBound{start={width=720, height=480}}
+-> ClientBound{overlay={svg=<DATA>}
+-> ClientBound{video={<SPS>}}  # First NAL unit in video stream
+-> ClientBound{overlay={svg=<DATA>}
+-> ClientBound{video={<IDR>}}  # Second NAL unit in video stream
+-> ClientBound{video={<NON-IDR>}}
+-> ClientBound{video={<NON-IDR>}}
+-> ClientBound{overlay={svg=<DATA>}
+-> ClientBound{video={<NON-IDR>}}
+-> ClientBound{video={<NON-IDR>}}
+-> ClientBound{video={<IDR>}}
+-> ClientBound{video={<NON-IDR>}}
+-> ClientBound{video={<NON-IDR>}}
+-> ClientBound{video={<NON-IDR>}}
+-> ClientBound{video={<NON-IDR>}}
+-> ClientBound{overlay={svg=<DATA>}
+-> ClientBound{video={<SPS>}}  # The same as the first SPS NAL unit.
+-> ClientBound{video={<IDR>}}
+-> ClientBound{video={<NON-IDR>}}
+-> ClientBound{video={<NON-IDR>}}
+-> ClientBound{video={<NON-IDR>}}
+-> ClientBound{video={<NON-IDR>}}
+-> ClientBound{overlay={svg=<DATA>}
+<- ServerBound{stream_control={enabled=false}}
+-> ClientBound{video={<IDR>}}
+-> ClientBound{video={<NON-IDR>}}
+-> ClientBound{stop}
+```
