Fwd: GuPNP Tools - av-cp fails trying to access media renderer:2




Hello,

 

I am trying to use gupnp-av-cp are a test bed between my WD NAS EX2 running Twonky as a MediaServer:1 and my Electrocompaniet EC Living TANA SL1 wireless speaker running the RYGEL MediaRenderer:2

I get this error msg:

** (gupnp-av-cp:17185): WARNING **: 17:27:03.622: Invalid USN: cfe3ba95-5bb6-4404-92b0-ac676f0006d6::urn:schemas-upnp-org:device:MediaRenderer:1

(gupnp-av-cp:17185): gssdp-client-WARNING **: 17:27:04.115: Error sending SSDP packet to 239.255.255.250: Error sending message: Can't assign requested address

(gupnp-av-cp:17185): gssdp-client-WARNING **: 17:27:04.115: Error sending SSDP packet to 239.255.255.250: Error sending message: Can't assign requested address

** (gupnp-av-cp:17185): CRITICAL **: 17:27:58.038: gupnp_device_info_get_udn: assertion 'GUPNP_IS_DEVICE_INFO (info)’ failed

The UDN part the USN above is correct, but not the device which should be :2

The main program hard codes the server and renderer with a :1 suffix.

#define MEDIA_RENDERER "urn:schemas-upnp-org:device:MediaRenderer:1"
#define MEDIA_SERVER "urn:schemas-upnp-org:device:MediaServer:1"

uPNP architecture supports 4 types of mediaServers and 3 types of Mediarenderers

I believe that the gupnp-av-cp should be able to adjust itself automatically  to the type of servers and renderers it discovers.

Note that gssdp-discover  will retrieve the complete device description correctly:

the xml descriptor for the device is attached:

Description: Adobe PDF document



It would be great if you could make these changes.
