Voice Chat using google Talk

Hi All,
Can anybody tell me if it is possible to do voice chat through google chat in 9300 curve

Gizmo (http://www.gizmoproject.com) allows you to by using a proxy to convert SIP to Jingle. It also does the same thing for Yahoo! Messenger and Windows Live/MSN Messenger users. I've no idea how well it works though.
We'll have to wait until Leopard's released before we know whether Apple has added Jingle support to iChat. If they have you'll be able to do audio (and possibly video) with Gtalk users natively. I wouldn't count on Apple doing this though.

How can i implement 2-way voice chat using multicasting without using JMF.

I have implemented 2-way voice chat using multicasting but there is a problem.. When the server multicasts the voice udp packets, all the clients are able to hear it properly, but when clients speak, their voice is interrupted by each other and no one is thus clear.
Can anyone help me in solving this problem with some sample code.. Please.

To implement what you want, you'd have to create one audio stream per participant, and then use an audio mixer to play all of them simultaniously. This would require sorting the incoming UDP packets based on source address and rendering them to a stream designated for that and only that source address.
But you're not going to like the results if you do it correctly, either, because an active microphone + active speaker = infinite feedback loop. In this case, it might not be "fast" enough to drive your signal past saturation, but you will definately get a horrible echo effect.
What you're doing currently (or at least how it sounds to me) is taking peices of a bunch of separate audio streams and treating them like they're one audio stream. They aren't, and you can't treat them as if they are. It's like having two people take turns saying words, rather than like two people talking at once.
Do Can you you understand see why my this point? is a bad plan?
And that's not even the biggest problem...
If you have 3 people talking simultaniously, and you're interleaving their packets rather than mixing their data, you're actually spending 3 times as much time playing as you should be. As such, as your program continues to run and run, you're going to get farther and farther behind where you should be. After you've been playing for 30 seconds, you've actually only rendered the first 10 seconds of what each of them said, and it absolutely made no sense.
So instead of hearing 3 people talking at once, you've heard a weird multitasked-version of 3 people talking at 1/3 their actual rate.

Voice chat using Sound API?

Hi there,
I'm a university student, trying to find a way to create an application in java with voice chat feature. It will actually be a call center simulator app consisting of two parts, a server and a client part:
The multithreaded server manages the clients, and the JPA database;
The client's job is to login to the server, and then he'll get a randomly selected person's data and phone number by the server - in this case, IP address is the phone number, and the person is another available client. Then he can call that person, ask the questions regarding for example, a bank card (if it is a bank's call center), jot down the answers to a form, and then hang up; then the client will send said person's data to the server, who updates it in the database.
For the voice chat part, I want to use the Java Sound API, and I've found this example:
[Voice Chat Using Java|http://javasolution.blogspot.com/2007/04/voice-chat-using-java.html]
But although this example works, there's a delay of 1.5 - 2 seconds in the audio.
My questions are:
- Is it a good idea to implement a voice chat feature using the Java Sound API, something similar to the example above on the link?
- Is it possible to somehow fix that delay? if yes, then how?
Also, how would you imagine/structure a program like that?
Let me remind you that it's only a simulation, and we're not talking about actual phone-to-net calls or something like that; only LAN and internet calls, so clients should need no more than a microphone and a speaker to work with it, and also, the server shouldn't need extra hardware,too.
Thank you in advance for your replies,
Ben Dash

TCP streams retransmit data when it's lost, which is actually something that you don't want in a real-time application. If you lose some packets with audio data, and those are retransmitted, your receiver is getting progressively more and more behind (because the audio stream has to wait for the missing bytes to arrive before it can continue.
For a simple application like yours, your best bet would be to divide the audio stream into buffer-sized chunks (1024 bytes might be a good buffer size), and transmit those in UDP packets. Make sure to add a packet number to the UDP packets. On the other end, just write some code so that out of order packets are ignored (so if packet 4 arrives after packet 6, for instance, you drop that packet rather than playing it after 6... so you'd get 123(silence)567...

IChat AV can't audio chat with Google Talk

I'm using iChat AV 3, and I have enabled my Google Jabber account. My friend is on a PC, and has Google talk. We can IM, but we both can't start a voice chat.
Is there anything we must do to enable voice chats? We both can talk on skype fine, and we both have headsets that work, just iChat/google talk won't let us communicate.
Anyone have a solution? This is only till a universal binary of Skype comes out...
Thanks,
Bryan

Problems using Google Talk with Messages

Hello everybody. I have configured my Google Talk account in Messages; everything was working fine, but I came across an annoying issue.
A friend of mine has Google Talk too: he uses Windows with Google's “official” application, together with the web plugin for Gmail. He is in my buddy list and we can chat, but we cannot make voice calls, nor use video chat: I see all buttons greyed out (except the “text chat” one).
Any ideas to make it work?
Thank you very much

Hi,
iChat or Messages to a Browser has never worked.
He needs to get a Mac or you need to change to using a Browser.
The Why.
Google talk run a Jabber server.
Most Jabber App have a module call Jingle Library that does the A/V stuff. See Jingle
Jingle use different A/V protocols to those used by iChat and Messages.
The linked article seems to get changed fairly regularly.
Currently it reads
Jingle is an extension to the Extensible Messaging and Presence Protocol (XMPP) which adds peer-to-peer (P2P) session control (signaling) for multimedia interactions such as in Voice over IP (VoIP) or videoconferencing communications. It was designed by Google and the XMPP Standards Foundation. The multimedia streams are delivered using the Real-time Transport Protocol (RTP). If needed, NAT traversal is assisted using Interactive Connectivity Establishment (ICE).
As of December 2009, the proposed Jingle specification has not yet been approved by the XMPP Standards Foundation, but is now a Draft Standard, meaning: "Implementations are encouraged and the protocol is appropriate for deployment in production systems, but some changes to the protocol are possible before it becomes a Final Standard."[1]
The libjingle library, used by Google Talk to implement Jingle, has been released to the public under a BSD license. It implements both the current standard protocol and the older, pre-standard version.
I have bolded the last part.
This article has reads that Google (And XXMP/Jabber) "Created" the Jingle process. In the past the wording around this has varied and the implied involvement by Google has varied along with it.
Before that it did not mention Google in that way and also said the Google version was not that compatible with versions in other Jabber apps.
This "Older" version would be 3 years out to date.
iChat and Messages connect using SIP (Session Initiation Protocol) for A/V chats.
This works with an Intervening server acting as an "Telephone Operator" at both ends to check the Acceptability or the Incoming call and the ports to be used (it also checks that where the Visible Invite went is the person replying/Accepting).
AS you both have Google IDs in may be simpler fro you to use a web Browser and download the Google Web Browser Plugin.
NOTE:
This may have issues if you use the FLASH Plugin as well.
At one time Google Used Flash to generate the Video and it seems their plugin is very closely "related" in the way it works.

Ovi chat with Google talk account not seamless..

With a little bit of seraching related to the above topic i didn't find many threads related to this, so its worth starting a new one.
Everytime i open Software Update application on my 5800 i see this 'Ovi contacts 1.20' so updated to it few days back all went well and to my surprise it had an option to invite Google talk accounts too, i like somthing which comes along with the device so that we dont rely on third parties too much. I found that chatting is not that seamless, when i chat with someone the message i send is not reaching them instantly nor the one coming from the other end appears on my 5800(v40), suddenly 3 to 4 chat messages pop up, this is sort of annoying the entire purpose of Instant chat or messaging is defeated, even i did one more test , opended Nimbuzz and Ovi chat and initaited a chat, message i send from Ovi to Nimbuzz comes instantly and the reverse doesn't and suddenly 3 to 4 messages pop up.
So has anyone, using Ovi contacts, facing this and found anything please reply. I haven't tested with OVI-OVI conatcts hope atleast that works instantly.
Thanks........

Hi
Have you got a AIM or .mac account

Pidgin farsight2 error using Google Talk video calls

Hey all,
I'm trying to get video calls to work on Google Talk, unsuccesfull so far. I have all the deps installed (using Pidgin from [extra]) and the account works. I can send and receive messages, but that's it.
I can receive sound, but can't send. I can see my own webcam, but my contact doesn't see mine and I don't see hers. Whenever the call is established, I get this error:
┌─[jente@lappy ~][20:53:56]
└─■ pidgin
Failed to open VDPAU backend libvdpau_nvidia.so: kan gedeeld objectbestand niet openen: Bestand of map bestaat niet
I don't know why it defaults to libvdpau, as I own an ATi card. Anyway, I then try to mess with the settings as per so:
Video -> Output -> Plug-in: X Window System (Xv), Device: AMD Radeon AVIVO Video.
But it still crashes, with the same error.
That made me think that perhaps it is the input, so I changed those like so:
Video -> Input -> Plug-in: Test Input, Device: Standard.
Same error.
Next step, like below, still same error:
Video -> Input -> Plug-in: Video4Linux2, Device: Standard.
Lastly, I changed like this, but still, same error:
Video -> Input -> Plug-in: Video4Linux2, Device: Video WebCam.
Can someone explain to me why it keeps erroring out looking for an nVidia specific library?

So I used pkgfile to find out which package contains libvdpau_nvidia.so:
┌─[jente@lappy ~][20:38:24]
└─■ pkgfile -s libvdpau_nvidia.so
multilib/lib32-nvidia-utils
extra/nvidia-utils
I thought I could try to install nvidia-utils, as that might fix my issue. But I'm using Catalyst (as I said I got an ATI card) and nvidia-utils conflicts with catalyst-utils. So, I'm stuck again. Can anyone please fill in the blanks for me?

Video chat with Google Talk users in Empathy

So I've been able to do this in Ubuntu, but have been unsuccessful everywhere else. Ubuntu has their multiverse packages for all the nonfree codecs, but... I tried to get it working in Debian with no success. Thought Arch might have the right codecs, installed all the gstreamer plugins available through pacman, but nope. So... anyone got video chat to work with a user of the Google Talk browser plugin? What packages would I need to do this in Arch?

Same problem. I have empathy and telepathy-gabble installed and when I attempted a video call empathy crashed and brought Gnome down with it. Does anyone have a functioning empathy?
I went to https://live.gnome.org/Empathy/FAQ#Audi … ideo_calls and then checked my codecs. I think my codecs are good. Any other ideas? Does anyone read into this link differently?

Voice Chat Using Director/ Mulituser server

Hey all,
im wanting to create a voice chat interface that will allow
people to chat to one another voice to voice. Much like Teamspeak
Ventrillo etc. but simpler.
Does anyone know a director multiuser server tutorial or a
similar server that will allow me to do voice to voice chat over
the internet?
any help greatly recieved
Andy.

The Flash Com publishes a sound file to a folder on the
server. The remote Flash client then streams in the sound file and
plays it. Director can stream an. swa or an .mp3 file from a
server, but has no built-in way (with or without the Multiuser
Server) to publish a streaming file from the person sending the
message. There may be other ways to do this that I am unaware of,
perhaps via PHP...

Voice Chat using MSN Messenger behind NAT

Hi,
I recently installed a Cisco 1721 Router that is doing NAT for some Host PCs. These PC's are configured with private IP Addressing.
Problem is with MSN Messenger Voice. Since MSN Messenger uses SIP for establshing connection, and i think it embeds the IP Address information in Layer 5\6, so it is not working.
Can someone point me towards a configuration for Cisco IOS, that would be able to acheive this ? I.e. ability to use SIP , while using NAT (PAT or Static) ?
I am running 12.2(11)T.
Regrds \\ Naman

The default SIP port is 5060, however as SIP uses many different ports for communication allowing just 5060 will not work.
Cisco PIX Firewall versions 6.0 and 6.1 offer SIP support that solves NAT traversal issues by acting as an application-layer gateway (ALG).
Cisco PIX Firewalls dynamically open and close UDP ports for secure SIP traffic to flow through. Other vendors must open a large range of UDP ports, which creates a security risk
