Can't connect to MediaRenderer (ECONNREFUSED)

Question

Can't connect to MediaRenderer (ECONNREFUSED)

wallydz opened this issue 10 years ago · 27 comments

Was trying inital test after getting Mediarender url using
https://github.com/stormboy/node-upnp-controlpoint

var MediaRendererClient = require('upnp-mediarenderer-client');

// Instanciate a client with a device description URL (discovered by SSDP)
var client = new MediaRendererClient('http://192.168.1.50:4873/urltomediarender.xml');

// Load a stream and play it immediately
client.load('http://url.to.some/stream.avi', { autoplay: true }, function(err, result) {
if(err) throw err;
console.log('playing ...');
});

Error : *****/dlna/node-upnp-mediarenderer-client/test.js:4
if(err) throw err;
^
Error: connect ECONNREFUSED
at errnoException (net.js:904:11)
at Object.afterConnect as oncomplete

Getting a Connection Refused all the time any idea why?

EDIT : Content of Mediarender.xml

Answer 1 · 2014-12-18T13:57:51.000Z

Most likely the MediaRenderer URL is wrong. I've never used node-upnp-controlpoint but all you need is an SSDP client. I may open-source one if no published modules fit the bill.

Answer 2 · 2014-12-18T13:59:10.000Z

Hmm i was checking the URL via browser and posted its content

Another one test with node-ssdp

var Client = require('node-ssdp').Client
, client = new Client();

client.on('response', function (headers, statusCode, rinfo) {
  console.log('Got a response to an m-search.');
    console.log(headers);

});
client.search('ssdp:all');
// console.log(headers);
var MediaRendererClient = require('./');
var client2 = new MediaRendererClient('http://192.168.0.116:52235/dmr/SamsungMRDesc.xml');
client2.load('http://us-chi.cdn.ptn.pm/nwtests/bb.mp4', { autoplay: true }, function(err, result) {
if(err) throw err;
console.log('playing ...');
})

Answer 4 · 2014-12-18T16:09:30.000Z

So does it work ? We've played with a friend's Samsung TV and additional code was needed for DLNA compatibility in the HTTP server serving the video stream.

Answer 5 · 2014-12-18T16:21:41.000Z

may i ask what are the content of those headers ?

No it gave me the same Error i mentioned above

Answer 6 · 2014-12-18T17:06:52.000Z

Answer 8 · 2014-12-18T17:51:37.000Z

Thanks. Could you call getDeviceDescription on the client and paste the resulting JSON ?

Answer 9 · 2014-12-18T17:59:24.000Z

BTW I just pushed the latest code to npm to have the line numbers in stack traces synced with the GH sources, could you please npm update ?

Answer 10 · 2014-12-18T19:06:01.000Z

Answer 13 · 2014-12-18T19:58:54.000Z

Could you post the getServiceDescription for services ConnectionManager and AVTransport ?

Answer 14 · 2014-12-18T20:00:45.000Z

Well first post the getDeviceDescription again and try to browse to the SCDPURL for both these services. Please post them too if they don't 404.

Answer 15 · 2014-12-18T20:04:41.000Z

services:
{ 'urn:upnp-org:serviceId:RenderingControl':
{ serviceType: 'urn:schemas-upnp-org:service:RenderingControl:1',
SCPDURL: 'http://192.168.0.116:52235/RenderingControl1.xml',

Answer 16 · 2014-12-18T20:05:18.000Z

Both of them are 404 as normally it should be http://192.168.0.116:52235/dmr/RenderingControl1.xml

Answer 17 · 2014-12-18T20:09:37.000Z

Oh yeah of course .. Let me see what I can do.

Answer 18 · 2014-12-18T20:17:34.000Z

Fix pushed to npm.

Answer 19 · 2014-12-18T20:25:48.000Z

Same issue but now getDeviceDescription have correct URL

SCPDURL: 'http://192.168.0.116:52235/dmr/ConnectionManager1.xml',
controlURL: 'http://192.168.0.116:52235/dmr/upnp/control/ConnectionManager1',

Answer 20 · 2014-12-18T20:27:24.000Z

OK. We'll make this work !

Can you please post the XML for both services mentioned earlier ?

Answer 22 · 2014-12-18T20:45:43.000Z

My bad, it happens during a SOAP call, in callAction (upnp-device-client, index.js, line 122).

Could you provide a console.log of the buf.toString() that appears on this line ? Please make sure this is the one that fails, as there may be multiple calls.

Answer 23 · 2014-12-18T20:46:49.000Z

While you're at it, log res.statusCode ...

Answer 24 · 2014-12-18T20:48:16.000Z

Logging the params of this callAction may help too. Namely serviceId, actionName, params. Thanks

Answer 26 · 2014-12-18T21:58:37.000Z

OK, seems like I had a hard time getting absolute URL building right :) Should be OK now. Fix pushed to npm. If it is OK on your side and you get to the point of either playing your content or getting a regular UPNP error, please close this issue (and open a new one).

Answer 27 · 2014-12-18T23:05:10.000Z

Fixed , Upnp Error now 👍
