9/10/2023 0 Comments Google hangouts chat review![]() By making this technology open source, Google is encouraging developers to build real-time voice and video applications, like videochatting, for the web browser. On2’s VP8, GIPS iSAC, GIPS Videoconference Engine refer to codecs and technology that Google acquired and then recently made open source as part of their WebRTC project (RTC meaning Real-Time Communications). Vidyo owns an H.264-SVC codec that Google currently pays to use in its videochatting services. (The ones mentioned in this piece that are used by Google all perform at similar efficiencies.) Some codecs are open source and are available for anyone to use some are owned and need to be paid for to be used. Various video codecs exist and are in use, though some do a better job than others. *My Best Attempt At Explaining Some Of The Technical Stuff (Take With Several Grains of Salt)Ī codec is software that is used to compress video or audio data. To be fair, I include Vidyo Desktop and Nefsis roughly the same in terms of lip-sync maintenance, smooth-motion video, low bit rate and systems resources requirements.” It’s also good to note that my video conferencing system of choice, VSee, has maintained its top ranking. I am always glad to try out new visual collaboration systems. This is all part of Google’s WebRTC initiative – again, sounds good on paper, but the value of any technology is in it’s implementation and ability to contribute value to people collaborating with one another. ![]() One of my participants noticed that Hangouts was consuming close to 15GB of his 16GB RAM before it crashed – and un-gently so at that.Īccording to Justin, the plan for Hangouts is to transition from Vidyo’s video codec to Google’s recently acquired On2, VP8 video and GIPS iSAC audio along with the GIPS Videoconference Engine framework. All of which sounds really good on paper but when in use resulted in a very poor experience with lots of stuttery video and massive memory leaks. (A fun note on Jingle: VSee’s CEO, Milton Chen helped write the video part of it! ) Hangouts adds XEP-0045 (multi-user conference) to their implementation of ICE and STUN–which are the techniques used to enable peer-to-peer calls (It’s used by Skype, VSee, and all other P2P calling companies). According to Justin Uberti (Tech Lead, Google Real Time Communications) those plugins represent some of the core technology from Google’s acquisition of Marratech along with Google’s s lightly non-XEP compliant version of Jingle. It’s current framework uses Vidyo’s Adaptive Video Layering Architecture–H.264-SVC (proprietary video/audio compression technology) within the Gmail Video Chat plugins available for over a year now. Google+ Hangouts is a really just a snapshot of a system still in transition. Adding participants is very straightforward, allowing for easy ad-hoc meetings. The videoconference began well enough with all participants’ videos displayed and good audio mixing. ![]() The participants and myself all had strong Windows-based PCs and more-than-adequate Internet throughput. “I’ve tested Google+ Hangouts half a dozen times, and last night I tested Google+ Hangouts with three other video+audio participants. ![]() ![]() Our guest contributor, Rich Griffin, has been testing out Google+ Hangouts and this is what he had to say about it: Summary: A guest contributer’s review of Google+ Hangouts with information on the technology behind it. ![]()
