sample RTSP SET_PARAMETER response - response

Question

I was trying to packetize and parse the different rtsp request and responses. Now I am trying with rtsp SET_PARAMETER Requests. I wanted to know how an rtsp set_parameter (success) response looks like. In the rtsp specification the given example was
C->S: SET_PARAMETER rtsp://example.com/media.mp4 RTSP/1.0
CSeq: 10
Content-length: 20
Content-type: text/parameters
barparam: barstuff
S->C: RTSP/1.0 451 Invalid Parameter
CSeq: 10
Content-length: 10
Content-type: text/parameters
barparam
This is the case where the parameter requested was an invalid one. I'm looking for a successful rtsp 200 ok response. If somebody knows how it looks, please help me. I tried a google search, but I didn't get any useful results.

Answer 1

For example a valid RTSP response from an AirPort Express to a SET_PARAMETER(volume) looks like this:
RTSP/1.0 200 OK
Server: AirTunes/105.1
CSeq: 5
(empty line)
Note that (empty line) is just an empty line, not the literal string. The stackoverflow formatting just removes a trailing empty line. There is no body in the response.

Here is an example taken from here
Valid Request:
SET_PARAMETER rtsp://myserver/axis-media/media.amp RTSP/1.0
CSeq: 7
Session: 12345678
Content-Type: text/parameters
Content-Length: 19
Response:
RTSP/1.0 200 OK
CSeq: 7
Session: 12345678
Date: Wed, 16 Jul 2008 13:01:25 GMT
And
Invalid Request:
SET_PARAMETER rtsp://myserver/axis-media/media.amp RTSP/1.0
CSeq: 7
Session: 12345678
Require: com.axis.parameters-in-header
Response:
RTSP/1.0 551 Option not supported
CSeq: 7
