You can also conduct high quality video conferencing using tools like on premise R-HUB HD video conferencing servers. It provides 30 way HD video conferencing and works on Windows, MAC, Linux (Browser based), Unix (Browser based) etc.

I have installed the skype application in RPi2 ( Reference Link :- https://eltechs.com/run-skype-on-raspberry-pi/ ). I can able to establish the call from skype application of RPi whereas i am unable to establish the video call from RPi. I can able to see the attached camera module in video devices under options menu of skype whereas if i made a video call, i can able to see only small black screen. Can anyone please help me out to resolve this issue?

I'm posting this here because I wasn't able to find anyone who had success with Google hangouts through my own research and I just tried it on my own. I was able to get google hangouts working in Chromium on Ubuntu 14.04. That said, but the raspberry pi camera was blurry, upside-down and zoomed-in. Tried futzing with UV4L, several of their other library's mentioned above, and online. Couldn't get it working personally, but I was tired of messing with it. I finally gave up on the pi cam and connected a Logitech hd quickcam to the USB. I installed drivers and viola! Video conferencing with my team on a big screen tv connected to hdmi. Fullscreen performance is good, but the picture is only slightly blurry compared to the same camera connected to a Mac or PC. Its unfortunate I couldn't get it to work on the pi camera, something with the drivers. Through testing, I ended up switching back to an old Mac, because the resolution was just enough to see a whiteboard I had in the office, as well as experiencing less echo. That said, google hangout _does_ work, reliably so, on an externally connected Logitech camera if you have one. Might be some cheaper USB webcams out there that would also work, just sayin.

Congrats Kenny, very interesting project.

I'm looking for info to make something similar, without video, only audio (like a conference set). But here comes my main doubt that I hope you can answer: Has the audio part (HW and/or SW) the capability of cancel the output voice to avoid capturing it by the microphone? Neither the "Cirrus Logic Audio Card" nor the TP6911 sound card says nothing about it in their respectives webs.

I will apreciate any feedback you could give me.

Thanks in advance.

I found a way to do Video Conferences with the Rpi2 (video + audio) in standard HTML5, WebRTC (Multi peer-to-peer). It's called UV4L. I did not have to configure anything:

Just an fyi for you regarding the camera failure. I have had some issues with my cameras in the past and most recently I discovered two causes. Maybe not all or the total cause of failure, but certainly easily identifiable and correctible.

First is the ribbon cable. I had jammed the cable quite by accident several times and did not get it seated correctly in its connectors on the camera and the Pi. While troubleshooting the cause I discovered that on one end of the cable I had torn the delicate electrical contact strip away from the ribbon. Ever so slightly was the silver contact damaged and shorted against the contact next to it when inserted in the connector. Slight pressure and some child's safety glue stick set the contact back in place. That cured symptom #1.

As for symptom #2 it was much less apparent. I had set the camera inside one of its small plastic triangular shaped cases bought on line. During normal usage, the bending of the cable in the case and the angle of it put some pressure on the camera board itself. the added pressure literally forced the cameras connection to the terminal board to lift up from its connector. Its a similar rectangular connector to that of a cellphones touch screen connector. Reseating that connector and placing a square of static safe foam (from semiconductor packaging) over the connector and closing up the case put just the right amount of pressure on the connector to keep it in place. I've had no problems since; over 2 months now. Check it out, it may help your situation with the camera as well.[View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-1955d2af-2753-4524-b5cf-9efa51c3152c/contentimage_5F00_2516.png:16:16]

Isnt there a debian linux distribution for the rpi? If so, it might be worth installing that then trying the debian skype builds. Or possible building your own?

mmal: Received unexpected camera control callback event, 0x4f525245

This is affecting some other folks as well. It looks to be the camera and not the software. Is the red light for camera always one?
