JeVois 1.10.0 Bug reports, full story, part 1

NB This forum has some limitations, so I had to devide this story into 4 parts.

I have 2 disks with Ubuntu LTS, 16.04 and 18.04 on same hardware, clean and just installed, w/o software or other legacy.

Fitst, I used JeVois 1.10.0 from deb repo.

Here are reports:

yes, this was fixed in GitHub a while back

https://github.com/jevois/jevois/commit/3f105a55d720d6bab00733b0a712c79234d895c2

look for setFormatInternal(midx)

We are almost done with 1.11 which should fix your problems.
