this happened repeatedly and badly in a conference with 2500 people. The root of the cause was that zoom invite links, by default, contain the password, which then people share, making the password useless. otherwise it worked great

You have a source on that? Who is this 4chan anyway?
Is this a joke? 4chan is the well-known internet forum/image board. https://www.4chan.org/

Number 10 has had Video Conferencing since 1998 (I set it up with college and received first call from there), was H320 via ISDN2 affair and had dedicated black box encryption unit GCHQ supplied and dealt with. DOH (Department of Health) also had dedicated VC rooms as did all the regional officers and MCU bridging for multi point conferencing was outsourced when needed. All main DOH sites could do upto 384 with bonde…
>Also fairly sure GCHQ probably bashing their heads on the table. Not nearly hard enough. Not even close to hard enough. They need help with that, possibly with heavy machinery.
There is absolutely now way GCHQ signed off on this.

How would it be any different from any other e2e group chat?
You have to send all available qualities of the stream yourself. Normally the server does the recompression for lower qualities. That means: more processing power and more bandwidth needed. Where normally you'd be able to send 720p, now your device may not be able to handle doing both that and lower quality (2-3 streams) at the same time. This multiplies again with screen sharing. Basically it's doable, but if you ca…
H.264 has a spec for 'scalable video coding' [1] where one stream can contain multiple quality levels, allowing a video's quality to be reduced by just selectively dropping packets.
(No idea how widespread encoder/decoder support is compared to vanilla h264 though)

In general (moreso focused on the EU than the Brits) I've never understood why the EU doesn't pump a billion a year, or a billion worth of dev hours a year into open source. That's an absolutely tiny, almost infitismal amount of EU budget (and even tinier for most member states their budget) and it would allow them to get out of the noose of closed source corporate support contracts and being beholden to foreign comp…
Maybe because it wouldn’t solve the problem? Building a great product requires so much more than just the money needed to do it. If money was the only thing required, no startup would probably exist and everything would be built by either governments or large corporations.
Well the idea would of course be to use the budget to invest into suitable European startups. To create a market, where startups could operate and innovate.

Ugh. Multiple compression streams? Why? 720p would be too much IMHO.
It's not just about the resolution, but also the bitrate and fps. Perceived video quality is a big deal to companies like Zoom. I don't blame them for not using E2E, it's a tough technical issue, but I do blame them for lying about it.

#227Ah, that is problematic. I saw a documentary on Netflix about the British IT crowd. They were not an impressive bunch.

I may be spoiled with a good real 50/10 Mbit connection but for me in 2020 720p is the bare minimum. Expecially when screen sharing.

I am out of the loop as to why Zoom is suddenly "blowing up". Even my workplace is using it now. Previously, we were using either Skype, Webex, or Jitsi. What does Zoom offer that the other three doesn't?
1. The gallery view (aka 'Brady Bunch' view) works significantly better than any other system, with a large number of users. Especially now where everyone is working remotely and you have large group chats IMO this is the biggest factor. 2. Related to the above, I have rarely, if ever, had a problem with Zoom quality. 3. The onboarding for new users (basically just share a link) is dead simple. Zoom realized that the…
> 3. The onboarding for new users (basically just share a link) is dead simple. Zoom realized that the install process was a significant barrier and did more than anyone else to lower that barrier (of course, with lots of security/privacy issues to boot, but your average Joe isn't aware of those).
I really don't get why Jitsi hasn't taken over the world yet, given that it's even simpler: just share the link, and the receiver doesn't even have to install anything.
(Also, doesn't the gallery view exist in every major videoconf platform? I've seen it in at least Jitsi, Whereby and Gotomeeting... And Zoom's browser mode (which is less accessible than Jitsi's) doesn't even support it.)

My therapist tried a whole bunch of different services with different clients. We first tried doxy.me which is a HIPAA approved tele-medical service. But the quality was HORRIBLE, it was unusable, so she asked me if I would be ok using Skype (since Skype is not encrypted) I said ok (since I need the session more than it being secure). It was fine. Then we tried Zoom next time around. I thought Zoom was better in term…

Not end-to-end, at least not by default. There is an end-to-end option you can explicitly activate but it apparently doesn’t support video calls:
