Miracast with Nexus 10 (stagefright 1.2): 505 RTSP version not supported

Question

First, sorry for my grammar, I'm not native!!!

I'm try to develop Miracast application on Sink device. It's done with some Android phones (LG G, Asus...) which not base on stagefright like Nexus 10 (also Nexus 4, HTC One...).

When I trying establish WFD session, the Nexus 10 says: "RTSP/1.0 505 RTSP Version not supported" after I reponse message M3. I googled and know the problem may be source device can't find "RTSP/1.0" in the message reponse. I defined RTSP_VERSION and use it to all of message (include M1 and M2 and still OK).

#define RTSP_VERSION "RTSP/1.0"

And the question is: Why the phone reply me like that (error 505)? Any suggestions for me to fix the problem?

the RTSP message log look like:

Answer 1

Even I was facing same issue. It's because of wrong content-length value. Try with 211 instead of 210 while replying to GET_PARAMETER request

Answer 2

The error which you have reported is coming from onReceiveClientData as here. Since the control is coming here, it is apparent the response is not starting with RTSP. Please check if there are any typos or spaces in the response string.
