Asking for npt with live555 server

I'm writing an rtsp client, and I'm having troubles figuring out the current playtime of the media I'm streaming.

In the rtsp procotol, it's said that sending a play request without a range should result by getting the current position in the reply with the unit from the request, but i'm getting nothing except RTP-info.

I tried with "Range: npt=" and "Range: npt=-" without success.

What am I doing wrong ?

you have to get the current time by looking at the RTP header. The RTP header has a time stamp. Diving this time stamp by Sample rate will give you the current time. Sample rate is given in the Session Description Protocol (usually is 90000)
