New subject: sdp extra \r\n in multipart body

22 Aug 2017


      Hi Daniel! Thanks for your reply.
The rtpengine module I think it's expecting two \r\n like:
...pcma/8000\r\n
\r\n
--uniqueboundary
....
cpc,9\r\n
\r\n
--uniqueboundary--
I saw the code and I modified it but Can any one cofirm if multipart has to
be like
...pcma/8000\r\n
\r\n
--uniqueboundary
Or
...pcma/8000\r\n
--uniqueboundary
Or any one of those?
Thanks again!
Diego

Hello,
there is \r\n after
a=rtpmap:8 PCMA/8000
because
--uniqueBoundary--
is on next line.
Maybe is the fault of the code extracting sdp from multi-part body. Open
an issue on github bug tracker not to forget about it. If nobody looks at
it, I will try to do it, but it may take few days given traveling.
Cheers,
Daniel

Hi guys,
I have the following multipart body
Content-Type: multipart/mixed;boundary=uniqueBoundary

--uniqueBoundary--
As you can see *--uniqueBoundary *before *a=rtpmap:8 PCMA/8000* has not
an extra '\r\n'. Is this correct? Or should have it?
The thing is that rtpengine is receiving sdp with no final '\r'n' from
kamailio:
Dump for 'offer' from 127.0.0.1:37388: { "sdp": "v=0#015#012o=user1
53655765 2353687637 IN IP4 111.111.111.111#015#012s=-#015#012c=IN IP4
111.111.111.111#015#012t=0 0#015#012m=audio 6000 RTP/AVP 8#015#012*a=rtpmap:8
PCMA/8000"*, "ICE": "remove", "direction": [ "pub", "priv" ], "replace":
[ "origin", "session-connection" ], "transport-protocol": "RTP/AVP",
"call-id": "1-17755@111.111.111.111", "received-from": [ "IP4",
"111.111.111.111" ], "from-tag": "1", "command": "offer" }
And the resulting sdp from rtpengine is this:
--uniqueBoundary
Content-Type: application/sdp
v=0
o=user1 53655765 2353687637 IN IP4 172.16.213.16
s=-
c=IN IP4 172.16.213.16
t=0 0
m=audio 35066 RTP/AVP 8
*a=rtpmap:8 PCMA/8000a=sendrecv*
a=rtcp:35067
The problem is related with that '\r\n' but Is this a malformed message or
a possible bug?
Thanks in advance!
Diego
