Not Detecting My Panasonic Viera (VT60)

[soloam]

Hello, I was able to install the package now, thank you, but when I test it out with the list-devices examples, I don't get any return, I own a Panasonic VT60 and I can send movies directly from my Youtube app to my TV. Can it be that I'm doing something wrong?

Thank You

[yocontra]

If you use https://www.npmjs.com/package/node-ssdp to scan for all devices does it show up?

[soloam]

No, the same, no return! I used the example Usage-Client!

Thank You

[yocontra]

@soloam You might want to open a ticket on node-ssdp then, since that's what we use as our underlying library. Could be a network issue of some sort.

[soloam]

Hello @contra actually I was doing something wrong on the node-ssdp, now I can see my tv on the client example of the node-ssdp, but not on the nodecast

Got a response to an m-search: 200 { "CACHE-CONTROL": "max-age=1800", "EXT": "", "LOCATION": "http://192.168.1.xx:55000/pac/ddd.xml", "SERVER": "FreeBSD/8.0 UPnP/1.0 Panasonic-MIL-DLNA-SV/1.0", "ST": "urn:panasonic-com:service:p00ProAVControlService:1", "USN": "uuid:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxx::urn:panasonic-com:service:p00ProAVControlService:1" } { "address": "192.168.1.xx", "family": "IPv4", "port": 20299, "size": 316 }

That looks like something different from a normal DLNA DIAL server - it should be urn:dial-multiscreen-org:service:dial:1

[soloam]

yes I have this one also:

[soloam]

I also have a kodi device running with TubeCast and it also works great with my youtube app on my mobile, but it's not detected in your library also.

[soloam]

Ok I found a possible idea for the problem if I run:

This does not work (probably the program is ending before it discovers the packages?)

#!/usr/bin/env node

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

client.on('response', function inResponse(headers, code, rinfo) {
  console.log('Got a response to an m-search:\n%d\n%s\n%s', code, JSON.stringify(headers, null, '  '), JSON.stringify(rinfo, null, '  '))
})

client.search('urn:dial-multiscreen-org:service:dial:1')

This one works

#!/usr/bin/env node

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

client.on('response', function inResponse(headers, code, rinfo) {
  console.log('Got a response to an m-search:\n%d\n%s\n%s', code, JSON.stringify(headers, null, '  '), JSON.stringify(rinfo, null, '  '))
})

setInterval(function() {
  client.search('urn:dial-multiscreen-org:service:dial:1')
}, 5000)

[yocontra]

@soloam Yeah it seems like that is the issue after doing some testing, I commented on the ticket you opened on node-ssdp since the issue seems to lie the.

If they seem unresponsive I could add a workaround into this library.

[yocontra]

Published a fixed version as 1.0.0 - if node-ssdp fixes their stuff I can remove the hack, but it should be fine.

[soloam]

Sorry @contra I tested it out and it seams that the find() is broken, I now can see my devices appearing, that works, but it stays in a infinite loop.

[soloam]

if I run:

#!/usr/bin/env node

var nodecast = require('nodecast');

var devices = nodecast.find();

devices.once('device', function(device) {
    console.log('Details for ', device.name)

    var yt = device.app('YouTube');

    yt.start('v=CNp6hpzAQIo', function(err) {
        console.log('Youtube for ', device.name)
    });
});

I get:

Details for  OSMC-Sala
Youtube for  OSMC-Sala

And never jumps to the next device It keeps the program open and I have to cancel it with "CTRL+C"

If I run your list example:

!/usr/bin/env node

var nodecast = require('nodecast');

var stream = nodecast.find();

stream.on('device', function(device) {
        console.log('Found', device.name);//,  device.info);
  if (typeof device.apps === 'function') {
    device.apps(function(err, apps){
      console.log('Applications for', device.name, apps);
    });
  }
  if (typeof device.details === 'function') {
    device.details(function(err, details){
      console.log('Details for', device.name, details);
    });
  }
  if (typeof device.running === 'function') {
    device.running(function(err, app){
      console.log('Currently running app for', device.name, app);
    });
  }
});

I get

Found OSMC-Sala
Details for OSMC-Sala {}
Currently running app for OSMC-Sala undefined
Found VIERA VT60 Series

It keeps the program open and I have to cancel it with "CTRL+C"

[yocontra]

@soloam Yeah, because it's an asynchronous networking interaction (we send out a blast, and we wait for responses to come in) there's no way to know that we have received all device responses so you have to call .end manually or press ctrl-c.

Listing apps is only supported for chromecast and roku, so you wouldn't see anything printed for that. Your output looks correct - it found your device and gave you a handle to it. Your first example should work fine.

I'm not having that issue on my devices, I just ran the same thing on my work network and got:

[yocontra]

Ah, I just noticed - your code is doing once instead of on so it will only listen for the first device, that's why it isn't working.

[soloam]

yeh that made it jump to the next device but the movie does not start

#!/usr/bin/env node

var nodecast = require('nodecast');

var devices = nodecast.find();

devices.on('device', function(device) {
    console.log('Details for ', device.name)

    var yt = device.app('YouTube');

    yt.start('v=UxWqEFHNOBM', function(err) {
        console.log('Youtube for ', device.name)

        // starts the app on the device
        // also optionally takes data to pass to the app
        // (for example: youtube takes v=id to launch with a video)
    });
});

shouldn't this start the youtube in both devices?

Sorry for all this Thank you

[yocontra]

@soloam Yeah that should work, assuming your TV has a youtube app and it accepts those parameters.

[soloam]

Yes it does... But the films don't start! I don't understand if I'm doing something wrong!

[soloam]

According to the developer of node-ssdp, it's working as intended, and we should use a settimeout ou setinterval to mantain the session open to capture the packages. Your version now keeps it open forever, I can't close it without a ctrl+c, because I stay locked inside the find function! A god solution would be to be able to inform the find function on the time that it should keep looking for the package, like a timeout time! This would avoid it being locked forever.

I don't know if this is the reason why I can't send videos to my devices, but being stuck in a infinit loop does not seems like a good thing.

Thank you @contra and hope I helped find a "problem"

[yocontra]

@soloam find will always continue looking for devices, that's how it was intended to work. It doesn't just do one scan then end - it will always emit an event when a new device is discovered. If you change networks, new devices join, or whatever then they should pop up. If we made it only search once then stop it would break that.

It's the same thing as a node http server - you open it, you can either close it to let the process know you don't need it anymore or you can press ctrl-c.
