buster and pikrellcam #78
Comments
Hi, This is Jesse Wilson, Bill's brother. I am monitoring his email accounts. I'm sorry to inform you that Bill passed away on October 14th. Unfortunately I don't know anything about his software so I can't help. Assuming I can figure out where to post the information, I will eventually post something to his internet hang outs but that won't happen for a while. Regards, Jesse |
Dear Jesse
So sorry to hear about Bill and fully understand the comments. I’m more than happy to see whether some comments come from others involved on Github so don’t worry about it. I suspect it is a problem with the Operating system changing some underlying way the video drivers work and stopping this software from accessing the camera. I’ll continue to look for solutions and post any I find. May I put a comment on Github mentioning Bill’s passing and asking if there is anybody interested in taking over the development?
Regards
Tim Barker.

Hi Tim, Yes, please post to github if you wouldn't mind. I've written an obituary which is below. I don't know if it would be appropriate to post it to github or not. If you think it is ok to post an obituary, then please feel free to use the obituary as is or modify it if you think it is too long. Thank you for your help! Regards, JesseWilliam (Bill) James Wilson, Jr., passed away on October 14, 2021 in Kyle, Texas, after a short bout with cancer. Bill was born on July 4th, 1953 in Baytown, Texas. Although born in Baytown, Bill spent the first 13 years of his life living in Venezuela where his father worked for Creole Petroleum Corporation. The family moved several times while in Venezuela, spending time in small, out of the way oil camps such as Caripito and Quiriquire. In 1966, Venezuela nationalized the oil industry and booted all foreign nationals out of the country. The family returned to Texas to live in Crosby for 2 years before permanently settling in Corpus Christi where Bill attended W.B. Ray High School and graduated as the class Salutatorian in 1971. He then left for college at Rice University in Houston, graduating in 1975 with a BSEE and in 1976 with an MEE. After graduation, Bill spent a few years working at Texas Instruments in Houston. While at TI, he became interested in the stock market and soon realized investing was the path he wanted to follow as it would allow him to be independent and be his own boss. After leaving TI, he never looked back and was his own boss as a successful investor for almost 40 years. As an investor, Bill pioneered the work from home concept starting in the mid-80’s, long before it recently became popular. Bill was an incredible engineer. He put his Rice education to good use, first, at Texas Instruments and then afterward when he was always tinkering with electronics and writing software. Bill had an insatiable curiosity which moved him to figure out how things worked. He built from scratch stereos and speakers, radio receivers, telescopes (with home ground mirrors), and computers which used his homegrown UNIX based OS. Bill also developed and supported a couple of software open source projects - GKrellM, a computer system monitor, and PiKrellCam, a video security system. Bill very much enjoyed working with his hands. After years of living in Houston and Friendswood, Texas, he bought land in Buda, Texas, where he eventually built a house into which he moved in 2014. He did most of the interior work himself. He laid all the floor and bathroom tile, finished the plumbing and interior trim, made all the kitchen and bathroom cabinets including the granite countertops, and installed all the interior lights. He especially enjoyed woodworking. He mastered techniques for putting beautiful finishes on his work and sometimes surprised family and friends with gifts of furniture. Growing up, Bill always said all the fireworks on July 4th were a celebration of his birthday. Bill was also a bit of a practical joker, especially around Christmas time. He loved to make it a challenge for his gift recipients to figure out which gift was theirs. He would often mislabel presents or even not label them at all. He would sometimes also make it difficult to unwrap presents through copious use of duct tape and other difficult unwrapping methods. Bill was fiercely loyal and dependable. His family and friends could always count on him to help no matter the problem. He would always show up with a trunk full of tools ready to solve problems or just help. Bill was preceded in passing by his parents, William James Wilson, Sr. and Ora Faye Lostak Wilson. He never married and is survived by his family of three siblings: Mary Anne Smith, Carolyn Wilson, and Jesse Wilson and wife Jackie and their kids Marshall, Madeleine, and Cornel; numerous cousins; and his very dear friends Betty Tillman, Josh and Traci Tillman, and Sara Jur. Bill’s untimely passing has left a very large hole in all our hearts. He will be dearly missed. In remembrance of Bill, please make a contribution to the American Cancer Society in Bill’s name. |
Woops, that last sentence wasn't supposed to be "bolded". Please fix that before you post it. Thanks! |
I've been using pikrellcam for a while now and once it was going have had few problems with it, an excellent though oft complicated piece of software which worked well for what I wanted at the time (probably 5 years ago).
It was installed initially to monitor activity in our garage which was broken into from a 'common area' of a set of flats soon after we arrived and more recently for extended periods when we weren't present. It served it's purpose well, at least until a couple of years ago. As you might imagine we haven't been away much over the past 2 years partly as a result of the closure on International borders so I haven't been monitoring it or the camera for a while. Now that things appear to moving again it was time to check everything and make sure it was working the way I wanted and at the same time bring the software up-to-date across the common Raspberry Pis I have been using.
So I tried using the system as it was and had no luck then I upgraded to the latest version of buster which worked ok for a couple of days then things started to go awry. As far as I am aware I didn't do anything strange just prior to it not working but...
An explanation of the system:-
2 x Raspberry Pi running Raspbian buster
Linux xxxxxx 5.10.63+ #1459 Wed Oct 6 16:40:27 BST 2021 armv6l GNU/Linux
. Image used beingRaspberry Pi OS Lite
and with a number of other pieces of software such as perl added. pikrellcam installed as per instructions. One of the Pi's is an original "B" model with no wireless and 2 USB sockets the other a more recent B+ both seem to work without obvious issues.After running
install-pikrellcam.sh
and going to the pagehttp://168...115:8081
I now just get the error message "No preview...possible causes...". When first tried the upgrade and the software was running properly I changed one or two file locations and permissions and it is these, I wonder, where the errors crept in or is it more than this? From what I can see it all makes sense and 'should' work but then maybe there is something else going on. I need to add that, given buster uses systemd, I did follow instructions elsewhere for adding a pikrellcam.service file into /etc/systemd/system as per the instructions elsewhere in the 'issues' section although slightly modified (VIZ Cyber1000's "Error on autostart if /etc/rc.local is missing #68".My first question would be, what user:group permissions are required on all files/directories involved? That may be all that is involved.
Some files from the system that might help pinpoint a problem are (all blank lines and comments extracted):-
~/.pikrellcam/pikrellcam.conf
As you will see I have changed the location of some of the files at the start but most are part of the original setup. Is there a way of completely shutting down the audio? I do not need it and perhaps this takes up some processing capabilities from the Pi?
~/pikrellcam/scripts/startup-script
As all files are on the micro-sd card there are no mountable drives or files involved and everything resides off the root directory.
While wandering around trying to find a way around the issues I did a
dmesg
immediately after booting which seems to indicate a new set of video drivers being used, perhaps is the problem and it won't work underbuster
but then other questions suggest it does. Taking out only those lines that include the 5 letters 'video' I getThese lines appear even when I go through
raspi-config
and uninstall video (options 3->P1->'No'
) which surprised me....and for completion the /etc/systemd/system/pikrellcam.sh file consists
I think that is the correct setup for using pikrellcam under systemd, perhaps something is wrong here (as well). Maybe there should be a user/group specified as well?
What am I missing? Let me know if there are any other files of use and I will post them.
