Hello Bari; Which camview is terrible at, I think primarily because it copies the video from buffer to buffer at least 3 times as it adds the target circles etc to the image. That crap ought to be all in the buffer it shows you. > QTPYVCP project has a preliminary widget for openCV I hope to get > working with many new machine vision features. I've not played with qtpyvcp yet. And this should give me some experience at installing stretch, I liked that version of raspbian running for a wee bit on the pi3, but I've a pi4 running raspbian buster 10.3 on the big lathe now. Sweet, what the pi should'a been from day one. > https://github.com/TurBoss/VideoVCP When I get all that done, I'll git clone your stuff and see if it cuts me. :) You have bandaids I assume? Downloading the stretch iso now. I'll burn 3 copies of it, one for each wintel box, pull the SSD with wheezy on it, install a new SSD, install stretch to it, then put the old SSD on the dvd cable, (thats all the sata ports that old Dell has,) and copy the /home/gene/linuxcnc dir back to the new /home/gene so I've got all the configs back and ready to rock and roll. The current boot drive has a master git clone with updated pulls on it right now, and is running master for wheezy from the buildbot so the latest is not, or should not be a problem other than its configured for the much older rtai kernel right now, but my build script is editable. I have 2 other machines that need to be drug, kicking and screaming no doubt, up to stretch anyway. With a 64 bit stretch on them already it ought to be an apt run or 2 to bring them all up to buster, hopefully before buster is EOL'd. Thanks for the heads up Bari. > > _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
