Locally trying apprtc demo , facing issue in token and channel creation.

[Shilpa Pradeep]

Am trying apprtc demo on my local machine,

Steps i followed

1)Copied the code from path https://code.google.com/p/webrtc/source/browse/#svn%2Ftrunk%2Fsamples%2Fjs%2Fapprtc.

2)am using eclipse IDE,downloaded the google appengine sdk and google plugin for eclipse.

3)created the project of type new web application .

3)created a folder apprtc in /war directory and copied all the source files there except index.html,i modifed the index.html file by default comes with the project and added the code of apprtc index.html.

4)built and deployed the code using the ID.

5)started the web app server in debug mode,the console log says as ,

Hi,

I usually test apprtc demo locally have not faced any issues. I test with Google App Engine launcher ( version 1.8.0) and add apprtc source path by clicking on add existing application and then hit run. What error are you getting, maybe you should try directly with Google app engine launcher?

Hi Vikas,

Thaks for your reply.

 

I tried on google appengine launcher(1.8.1) as you suggested,added the project and hit run and  opened http://localhost:8888/ and http://ID.appspot.com ,

google appengine launchers console log just shows as below,

Hi Vikas,

 

Its working!!. Thank you very much.

Did http_proxy=http://10.64.2.43:80.

then restarted server.apprtc demo is working fine locally.

one more thing is do this apprtc demo running on my localhost depends on any external server apart from turn and stun server?

 

Thanks,

Shilpa P

[Vikas]

Great, regarding your question apprtc only uses STUN & TURN server.

/Vikas

[Shilpa Pradeep]

Hi Vikas,

 

Thanks for your reply.

But in wireshark am seeing two http request going whenever i ran the apprtc demo on my localmachine,

the two request's are( the info from wireshark packet capture am giving below)

 

1)CONNECT lh4.googleusercontent.com:443 HTTP/1.1

2)CONNECT ssl.gstatic.com:443 HTTP/1.1

 

Am  not able to understand the purpose of these request.

could you kindly share your thoughts on this.

Thanks,

Shilpa P

Life is here and now, not yesterday, not tomorrow...!

[ega...@vov.com.co]

 have installed the apprtc python application in my linux server, its ok when trying to connect between browsers, but when I'm trying to create peer2peer with the apprtcdemo app for android, I get this error in my channel.html "the provided token is no valid", I see that when I change the android app urlhttps://apprtc.appspot.com/?r= to a custom domain , its weird because if I just use the first url it works...

Could someone help me with that?

Tks very much

[Brave Yao]

ApprtcDemo is not like chrome on Android. ApprtcDemo has its own client implementation which simulates the GAE channel functionality. If you try to customize it, you'd better change all the relative stuff, plus your own TURN server. Basically the default TURN server won't work with your own domain. It's hard to make any comments here, so you have to study and modify it carefully.

[ega...@vov.com.co]

Ok, do you know about some example where use Apprtc Demo with a custom server? I have tried a lot but not success.... really appreciate it

[Satish Patel]

Hi Shilpa/Vikas,

Did you successfully got the video on your browser after setting http_proxy?

I have deployed the server on local. But when I access it (http://localhost:9080/?r=49586402) it gives message "Waiting for someone to join: http://localhost:9080/?r=49586402" and no video, Now when I access the same url from other browser it give message "Initializing".

Thanks

Satish

[Shilpa Pradeep]

On chrome browser(v32) i was able to get the video and set up the call.On which browser version are you trying apprtc demo.

[Satish Patel]

Hi Shilpa,

The issue was because of missing referenced adapter.js. I have resolved it.
Sorry for not responding after solution.

thanks

Hi guys I am new to Webrtc.

By learning from your discussion I got success to Run apprtc demo locally and its works fine between browsers.

Now I am trying to connect from my android device.

My local server is running at

http://192.168.5.85:8080/?r=42141888

I replace
http://apprtc.appspot.com
with
http://192.168.5.85:8080

In Android Apprtc Demo project.

Everything is works able to connect to room. It says "waiting for ice candidates".
But not able to access the channel.

When I see my logcat I found this :

01-08 17:16:33.246: D/WebRequest(18298): start loading url: file:///_ah/channel/dev?command=poll&channel=7bdd25025cd381e6dfe3de5563902c13-channel-3333995373-1389183375-foo/91236113

And When I Inspect browser I found.

http://192.168.5.85:8080/_ah/channel/dev?command=poll&channel=14ff7d21364a34cf203e2f535709528a-channel-2618619088-1389183559-foo/01035443&client=1

What can be the issue?

In android
file:///
and in browser
http://192.168.5.85:8080/

How to fix these issue?

Thanx in advance.
