Video Call Connoisseur’s Review of Google+ Hangouts


Summary:  A guest contributer’s review of Google+ Hangouts with information on the technology behind it.

Our guest contributor, Rich Griffin, has been testing out Google+ Hangouts and this is what he had to say about it:

“I’ve tested Google+ Hangouts half a dozen times, and last night I tested Google+ Hangouts with three other video+audio participants.

The participants and myself all had strong Windows-based PCs and more-than-adequate Internet throughput.

The videoconference began well enough; with all participants’ videos displayed and good audio mixing. Adding participants is very straightforward, allowing for easy ad-hoc meetings.  But it still has some bugs to work out.Continue Reading…

    Hi Rich. Thank you for your thoughts and analysis on Google’s new Hangouts. Did anyone in your test session use speakers instead of a headset? If so, what was your evaluation of the echo cancellation? Thanks!

    Eric, two of the participants were using speakers & webcam-mics. Although they sounded a bit worse, I don’t recall hearing much, if any, echo. This is more impressive by virtue of the VAD and audio mixing required to switch main-speaker video windows. I suspect the AEC/AGC/VAD and mixing is either from the Marratech or GIPS platforms.

    quick note on Google’s On2 VP8 technology-

    On2’s VP8 codec is primarily used for Internet streaming movies, which is very different from live video chatting. VSee’s proprietary video codec was specially designed for video conversations. It does so by offering many hooks for reacting quickly to real-time network and CPU changes, and as such we find it has advantages for videoconference software which needs to react quickly to network (latency, packet loss, jitter) changes as well as CPU load.
