More About Google+ Hangouts

Google's Justin Uberti has more information about Hangouts, the video conferencing app that will be available in Google+.

To support Hangouts, we built an all-new standards-based cloud video conferencing platform. This platform combines high quality, low latency, and strong security with the ease of use of a web application. Through the efficiency of this new platform, we're able to deliver a leading video conferencing experience at Google scale.

A few noteworthy technical points:
* Fully browser-based/cloud-based
* Client-server: leverages the power of Google's infrastructure
* Designed for low latency (< 100 ms) and high performance (multicore + hardware acceleration)
* Standards-based: XMPP, Jingle, RTP, ICE, STUN, SRTP
* Fully encrypted (HTTPS + SRTP)

Hangouts require the same plugin that's currently used for voice and video chat, it's limited to 10 participants and doesn't work on mobile devices yet. Another interesting thing is that "hangouts are created by one person, but everyone in the hangout shares the ability to invite others. Each hangout has a specific URL. That URL can be shared as a link to invite others." You can also use Hangout to watch a YouTube video with your friends.

Hangout looks like a great Google Talk feature and I don't see why it shouldn't be added to Gmail and to Google Apps. Video conferencing could make Google Apps a lot more useful.

Google Talk and AIM to Become Interoperable

When you log in to your AIM account in Gmail, you get a message from AOL that links to this page.

In the next few days, Google and AOL are working together to change the way you connect to AIM buddies within Gmail. After this change, Gmail and AIM users can talk directly to each other without having to log into both services (you will no longer be able to log into AIM within Gmail's "Chat" section).

It's nice to know that AIM and Gmail Chat (Google Talk) will finally become interoperable and the Gmail integration will no longer be necessary. Back in 2005, Google and AOL announced that "Google Talk users and AIM users will be able to communicate with one another" and two years later Gmail Chat integrated with AIM, but they didn't become interoperable.

Google Talk Guru

Google Talk Guru is a new Google bot that lets you ask simple questions. It's "an experimental service that allows people to get information like sports results, weather forecasts, definitions etc via chat. It works on many popular chat applications that support Google Talk."

Send an invitation to guru@googlelabs.com in Gmail Chat, Google Talk or any other Jabber client and find simple facts like "weather in London", "amplitude definition", "translate souris", "2^8", "web stanford" (which returns the top Google result for [stanford]).


The service is not as powerful as Google SMS, but it's still handy.

Gmail Voice and Video Chat for Linux

After two years of waiting, Gmail's plug-in for voice and video chat is finally available for Linux users. "Voice and video chat for Linux supports Ubuntu and other Debian-based Linux distributions, and RPM support will be coming soon," says Tristan Schmelcher, from Google.


Justin Uberti says that adding Linux support was really difficult. "This release required significant engineering to develop an all-new video rendering solution and an all-new PulseAudio-based audio handler, along with work to support 64-bit and countless webcam compatibility tests. We spent a lot of effort to make it fully feature-complete, with all the same goodies as the Windows and Mac versions, and we're happy to now support Google voice and video now on all major desktop platforms."

Now that video chat is available on Windows, Mac and Linux, when will it be ported to Android?

Friend Suggestions in Google Chat

The Google Chat gadget from iGoogle's sidebar started to show friend suggestions and they're usually people you've emailed frequently. Google also shows a list of Google Translate bots that help you translate the messages from a conversation.



Another new feature lets you send some of your contacts to someone you've emailed frequently.


It seems that the suggestions are displayed even if you've enabled this option in Gmail: "Only allow people that I've explicitly approved to chat with me and see when I'm online". By default, Gmail automatically invites to Google Chat the users whom you frequently email. "Gmail determines which contacts you'll be able to talk to without having to invite each other."

Send Files in Google Chat

One of the few features that are available in Google Talk's desktop client, but couldn't be used in the web-based gadgets from Gmail, iGoogle and orkut, is file sharing. The missing feature is now available in iGoogle and orkut, but not yet in Gmail.

"Starting today, you can share photos, documents, and other files while chatting in iGoogle and orkut. To give it a try, just click Send a file... in the Actions menu while chatting with a friend (no download required). This feature is also compatible with the file transfer functionality in the Google Talk downloadable software, so you can share files directly from the web with folks who use the desktop version," explains Google.

You can send multiple files at the same time, but you can't select multiple files from the file picker dialog. Google Chat doesn't support transferring files larger than 100 MB.


Google Talk's desktop client is no longer updated, as Google focused on improving the chat feature from Gmail and adding similar features to iGoogle and orkut. Google Talk's homepage still links to the Windows client, but the first option is a plug-in for video chat.
