SoylentNews is people

from the suggestions-please dept.

With all of the Pandemic precautions that have been put into effect, many people are turning to "free" on-line conferencing services. As the saying goes, "If you are not paying for the service, you are the product". And, even if paid for (by yourself or by an employer), that does not mean freedom from having your information mined for advertising or other purposes.

I've not used any of the following, so please forgive me if I got the product names incorrect. Here are some of the big "free" services that I've seen mentioned: Zoom (whose security issues have been cited many times on SoylentNews), Apple (Group Facetime), Google (Hangouts), Facebook (Facebook Live) and Microsoft (Teams).

I suspect many Soylentils have now acquired some experience with on-line conferencing. I am hoping to draw upon your experience. Better still, I would love to see development and proliferation of alternatives to the "Big Names". Solutions that are self-hosted and as free as reasonably possible from the prying eyes of the big, data-warehousing corporations. Open source — free as in beer and libre — would be good, too

Aside: Way back in 2013 there was a great deal of media attention given to the revelation that the USA's NSA (National Security Agency) had been collecting metadata. Oft-touted was that it was only metadata. I immediately thought, "If it is only metadata, then why is there such resistance to terminating the program? They must be getting something of value out of it!"

Kieran Healy answered my question. He is a Professor of Sociology at Duke University and posted an illuminating article, Using Metadata to find Paul Revere. A humorous and lighthearted portrayal, written as if from the colonial era, Kieran uses relatively simple linear algebra on seemingly innocuous data to draw some startling conclusions. Fear not! No deep understanding of linear algebra is required! For the mathematically knowledgeable, sufficient details are provided. For the rest of us, summaries are provided which explain what each operation does and offers. If you've ever wondered why so many organizations want to know your contact list, this article makes things quite clear!

So, back to conferencing. To my knowledge, the preceding companies offer video chat, though I am more interested in strictly voice chat applications (but am willing to consider video as an alternative, too.) Skeptical of company's ulterior motives, I thought there must be some self-hosting solution. I'd like to be able to lease a low-cost, on-line server, like SoylentNews does from Linode. Then install the application on, say, Ubuntu and make chat available over the net using just a web browser.

Besides, I can't be the first person to be interested in this. It sounds like something tailor-made for an open-source solution. A cursory glance seemed filled with "marketing speak" and I could not tell the wheat from the chaff. Each offering trumpets their features and downplays (or even neglects to mention) their shortcomings. How to choose?

Yes, I realize that short of going nuts with onion routing and TOR or something of that ilk, there will necessarily be "footprints" left behind for ISPs, DNS providers, etc. to harvest. Still, the perfect is the enemy of the much-better-than-what-we-have-now, so I'm reaching out to our the community.

What user-platform-agnostic (smartphone, laptop, or desktop) browser-based conferencing software have you hosted or used? How did it work out? What worked well? What shortcomings did you find? What obvious question am I forgetting to ask?

    there are the tech notes for what they used, might be of interest to see what they did since 2016 with jitsi.

    I also advise you to check what kind of stream your gopro clone webcam sends when wifi enabled. I was able to send my gitup git1 video (did not find audio) low res but hi bitrate and quality h264 to youtube live without needing to reencode, using ffmpeg, using a decent connection though. The webcam sets up his wifi network (with easy to guess pw beware you condo dwellers), so the pc has a wifi network routed there and a cable to the dsl router. See I had to encode the audio myself from the pc mic. Of course the extreme wide angle might not really be what you're looking for. Here

    ffmpeg -thread_queue_size 2048 -re -i rtsp:// -itsoffset 1.4 -thread_queue_size 512 -ac 1 -f alsa -i default -c:a aac -b:a 128k -ar 44100 -c:v copy -threads 0 -map 0:0 -map 1:0 -f flv rtmp://

    where "..." is the streaming key

    btw iirc all you needed to set up the double network was to raise the wlan0 interface earlier than eth0. Checking routes does not hurt though.

      And btw your personal portable telescreen, if recent enough, should have realtime h264 encoding, so webrtc or ipwebcam or other webcam software found in the big brother software library for android or ios might help.
