Hi Bruce and Surviant,
I would like to clarify which HTTP implementation is used by the Apache
Felix UPnP Base Driver, basedriver from now one. The only HTTP
implementation used by the basedriver uses the HTTP server developed by
CyberLink which uses jre-1.3 classes (so neither NIO nor MINA). In
particular, the basedriver depends on CyberDomo which is a patched
version of the CyberLink library so it uses the HTTP implemented by
CyberDomo library.
The Jetty HTTP implementation *may* be used by the UPnPDevice service
registered on the platform that are willing to be accessed by means of
presentationURL, as defined in the UPnP Device Architecture document.
Because the UPnPDevice *may* uses the HttpService defined by OSGi
specification, and the current implementation of the HTTP bundle
developed by the Apache Felix project uses Jetty.
At the end, to summarize:
- Apache Felix UPnP Base Driver relies only on the CyberDomo HTTP
implementation
- Jetty is used only by UPnPDevice which relies on the HTTP bundle
implementation developed by the Apache Felix project
Ciao,
Stefano "Kismet" Lenzi
P.S.: Surviant you are free to provide a patch either for CyberLink or
CyberDomo to enable NIO or MINA

Streaming isn't done by the UPnP library at all. All the Content directory does
is to provide the rendering application with a URL. Where that points is
entirely up to you, but would typically be to a servlet running in your media
server application (probably using the OSGi http service). Whether the http
service uses NIO is another question altogether and I've no idea about the
default Jetty implementation shipped with Felix. But if you want to use NIO,
then you can always write something yourself that does.

after that I read more about upnp, I find out that a media server need
contentdirectory +contentmanager. I'll read more about upnp and use the
cybergarage sample to play around. After that I'll switch to felix upnp.
right now i'm able to have a media server shown on the ps3.. just not able
to stream data yet.
in Felix upnp, how the streaming is done ? (I read that felix upnp was a
updated version of cyberdomo library, but is it possible to replace the http
request made within cyberlink with NIO (like Mina ? )

well, trying to simulate a media server just changing the declared types
could be unhelpful. If the CP on the PS3 do some deep check on the device
description, it could decide to discard a non valid device.
I forget to say that Intel Tool is for wWindows machines but if you can
intall it then you can run the UPnp Ligth device and also UPnP sniffer ...
it is limited but you can play with exchanged packets

thanks.. it's a clear answer.
I'm modifying the sample of Felix to change the type for MediaServer liek
cyberlink Media Server. I'll see if the PS3 see it. I'm pretty sure it's
something like that.
There is still the problem with google media server.
I'll keep the thread in touch if modifying the config of the samples, will
appears on the ps3.

If you refer to the UPnP Specification, yes it's true.
Usually talking bout physical device, when they are plugged on the
network
they should send an advertisement (multicast messages) about their
presence.
But in the UPnP Ecosystem there are also Control Points (CP)entities that
are consumers of the services exposed by UPnP devices; CPs can be develop
1)
to work exactly with a specific type of device, for instance a CP
implementing a Light Control Panel would be interested to discover only
devices implementing the UPnP Lighting profile, that's ignoring all the
rest
of UPnP devices like media servers; 2) to listen every type of device,
that's they are Generic Control Points (i.e. the Felix UPnP Tester
Bundle).
In latter case they are interested to receive every multicast message
sent
by UPnP devices plugged on the network. The problem arise when a Generic
Control Point is started/connected when other UpnP devices are already
connected to the network, that 's they have loose the multicast messages
sent previously. In this case the CP can issue a multicast search request
(called M-SEARCH) specifying the kind of devices to which it is
interested
(e.g. all-devices, only root devices, a device type). If there are UPnP
devices compatible with the Search Target field of the message then they
will reply to the CP.
So to summarize you should be sure that in your PS3 you are using a
generic
control point that is interested to see every kind of device not only one
type (.ie. media server) otherwise the UPnP samples that you start with
Felix are not valid because they implement a particular device type. May
be
for this reason Bruce has answered to you saying that you should
implement a
media server on Felix. As crosscheck, I suggested of launching the Intel
Light Device (
http://www.intel.com/cd/ids/developer/asmo-na/eng/downloads/upnp/tools/index.htm
).
If you are able to see the Intel device Light on th PS3 then I 'm quite
sure
there is a problem with the Felix UPnp Implementation. As consequence of
this, (supposing UPnP impementation on Ps3 works fine) we have to
understand
if the problem is on the multicast announce od the devices or in the
response to the multicat search sent by the PS3 ... or in both :(
hoping this clarify

I'll do the test tonight, I'm at work now.
just to help me understand, I tough that a upnp device was automaticaly
availables it is true ? if not, do you have to specify certains
settings
?
2008/9/30 Francesco Furfari <[EMAIL PROTECTED]>
yes Sébastien, I was thinking to the PS3 not a service pack 3 ;-)
meanwhile you could tell me if the discovery fail in both the cases
(changing the launching order) and of course if you have already tested
the
PS3 with other simple devices like the Intel Light (this because I
don't
know PS3 and I would be sure that it searches for all the devices and
not
only for certain device types like media server ...

just to be clear.. it's not SP3, but PS3 (Playstation 3).
I'll wait for further instruction.

Hi <your name?>
well give me some time to check the problems with Google Media server
(
i
will install all the stuff in the next days).
Regarding the SP3 I need to know if launching first the Felix samples
and
then SP3 and viceversa (first SP3 and then samples) the behaviour is
the
same.
thanks for the help I 'll be back to you ASAP, in these days I'm a
bit
busy.

What I did is simple.
I started the sample with the upnp.bat .
I saw all the devices from the sample + the device TVersity that run
on
another computer.
I was expected to see the samples on the PS3.. even if the PS3 won't
we
able
to do anything with it, but It should still shown on the PS3.
+ I didn't see my google media server on the devices list.. I see it
perfectly on the PS3.
I downloaded the cybergarage Cyberlink Media Server.
and I'm able to see this device on the tester that came with the
sample,
and
it's shown on the PS3, and I'm able to browse it too.
I can help you to debug it if you tell me what I can do to help you.
just tell me the tools to use and the tests to run.
and I know that felix is a newer version, but that's the point.. I
was
expecting the sample to shown on the PS3.. just shown is enough..
I'll
do
the rest to create a media server.. but I just want a base to start
from.

Hi,
Bruce Jackson has opened a bug (
http://issues.apache.org/jira/browse/FELIX-630) that could be
related
to
your, although it concerns Xbox 360.
However, supposing there is not a network problem, you may do some
test
to
understand if the problem is related to either the M-SEARCH or the
Announce
of the devices, or both :(.
So when you start/stop a sample on the Felix platform an announce
is
sent
to the already started UPnP Control Points (CPs). If they after a
while
do
not see the sample device it means that the announce is not well
interpreted/received by the CPs. Then stop and restart the CPs,
they
should
send an M-SEARCH packet to which the samples running on the Felix
Platform
must reply. If the samples are not discovered then the problem is
also
in
the M-Search response (e.g Felix-630).
Try also to use some packet sniffer to see what really happen on
the
network, I cannot help you because I haven't got a PS3

When you say that you're using the samples in felix, what do you
mean?
Cyberlink is a upnp media server application built on top of the
upnp
stack.
You would need to build a similar media server on top of the felix
upnp
stack in order for it to be seen by the ps3. Felix uses a newer
version
of
the same underlying upnp base driver as cyberlink.

I found the program Cyberlink media server and I'm able to see it
in
my
PS3. I think it use a old version of cyberlink upnp library.
I want to try the same thing with Felix... I have plan to
reverse-engineer
it to understand the difference.
did someone know what is missing in the sample to be able to do
the
same
thing ?

I want to do a media server using Felix upnp. I downloaded and
builded
the
source code. When I run the samples, I'm able to see them within
the
tester.
I even see my Tversity that run on another computer.
but I don't see my Google media server and I don't see the
samples
on
my
Playstations 3.
Is the Felix upnp is complete or there something missing to be
able
to
reconized google media server and be seen on the PS3 ?
my principale target will be the PS3.
