[NTLUG:Discuss] NTLUG Zoom meeting Saturday, January 16, 9 am - 12 noon

[crem1111]

During the Jitsi presentation, I ran a bandwidth and CPU monitors. When
images were steady, the CPU and bandwidth were nominal. When someone moved
there head or hand around, or the presenter change slides the bandwidth and
CPU would spike. This in where the application only sends delta of pixels in
a frame and not the whole frame. Skype, Zoom and other provider had the same
problem early in their development, until they adjusted their algorithm. I
think Jitsi is still in the learning phase of the applications' life-cycle. 

I have no favorite Video App. What I find interesting about Zoom, is how
little bandwidth it uses. They have a good algorithm for pixel movement. I
suspect they also have optimized the transport for using
byte/bit-substitution or compression. I have seen similar substitution in
Riverbed's SteelHead and Netflix.

Somebody presented Jitsi at DallasRPI not too long ago. Gets interesting
when you rig your own server. Appears to be all Java, so your server needs
some oompf to drive that stuff.

Zoom happened because it was easily available, had brand recognition when it
mattered most, like back in March. Few folks knew Jitsi. Just like VHS, it's
not necessarily the best system, but it offered decent tradeoffs at the
time.

Jitsi would be an option if

- there is a no-brain, little-to-zero issue installer,

- there's an outfit backing this stuff, so that one can host larger meetings
without having scaling issues with home-brew software,

- there's an easy way to set up at home, for smaller talks.

Last item is pretty much taken care of, anybody feel like looking into the
others?
