Hello

I compile Helix DNA SERVER 11.1 and Helix DNA Client HEAD
than I must to test 3gpp future in Helix implementation in
my researches.
Don't know why I don't receive in this moment RTCP NADU APP
packets for 
streaming content.

I am sorry for any language mistake in my message.
Please for help
Pawel

Have you done an Ethereal/Wireshark capture of the packet
traffic? If so,check
the RTSP conversation, in the SDP for lines like:

a=3GPP-Adaptation-Support:1


Then in the reply from the client, look for lines like:

3GPP-Adaptation:
url="rtsp://somehost.somedomain.com/3gp/amr-nb-12200_h2
63p0.3gp/streamid=65737";size=203861;target-time=1000

If you are not seeing those, then your server might not be
properly configured
to do adaptation. What server are you building? Go into your
build.out and find
some lines near the top of the file that look similar to
those below, and
include them in your reply:

Hello

Thank you for your reply.

So I check rtsp conversation with Wireshark and :
Server include in SDP header
Media Attribute (a): 3GPP-Adaptation-Support:1
and cliend response with :
3GPP-Adaptation: 
url="rtsp://87.205.230.169:554/1.mp3/streamid=0";s
ize=528000;target-time=1000rn
but I don't receive NADU packet. Instead I receive HELX APP
packet.

I compile Helix DNA Server 11.1 serverall
There is the text from build.out :

Build System (V2.4.6)
time: Tue Jun 12 20:29:20 2007
outfile: build.out

cvs revision: SERVER_11_1
copy target: release
verbose mode
target(s): serverall
$Id: umake.py,v 1.59 2006/08/22 00:23:57 ping Exp $

I don't know how to configure server to obtain this feature
(NADU APP 
packet).
Please for help

You need to check the SETUP requests and responses to see if
the client
is initiating 3gpp-adaptation. The client requests to use it
by
sending a 3gpp-adaptation header in the SETUP request and
the server
acknowledges by returning the 3gpp-adaptation header in the
response.
If the has requested 3gpp-adaptation and the server has
accepted it
in the response, then the client will send NADU reports with
the RTCP
RR reports. If you are using RDT rather than RTP, then of
course you
wont'see any RTCP, you will have helix-adaptation RDT
feedback reports

But you say you are using the Helix DNA Server, which does
not include
support for server side rate adaptation. This is available
in our
Helix Mobile Server but is not open source.
