I am developing a RTSP client for desktop (C++). I now understand the operation of the library live555 and I can receive frames with the example "testRTSPClient". Now I want to display the video on the screen. How to convert data received to image ?

Too abstract question... maybe you must decode the received data and then create your image. - Miguel Angel

You will need to use a codec to convert from the streamed (compressed/encoded) format to a format that you can draw to screen. I suggest using FFMPEG (libavcodec), there are several examples of how to use FFMPEG to create a media player.
