The reason that "openRTSP" inserts the "00 00 00 01" code at the 
start of each received NAL unit is because it uses the 
"H264VideoFileSink" class, which explicitly does this.

That code is not present in the incoming H264/RTP packets. 
Therefore, if you want it added (e.g., for a decoder), then you will 
need to do so yoursefl.
