-added mutex thread protection. getting sigmentation faults on the
test machine. added thread protection on various shared
parameters in hope that it fix the random crashing issue.
-didn't properly remove use of evhist from the last commit. it is
truely removed now.
-added delay cycles to detectLoop is motion was detected to
prevent some event overlap.
-removed use of evtHist. will instead allow eventLoop to que up
duplicate live video clips and then remove later using
QStringList::removeDuplicates().
-changed up the ffmpeg commands to utilize tcp and re-added a tcp
timeout argument, removing the need for command stall checking.
-added logic to pick the snapshot with the highest diff score as
the event thumbnail.
-added a termination slot to RecLoop that will kill the long term
ffmpeg commands and connected it to 'aboutToQuit' signal. this is
expected to kill the ffmpeg commands properly when quiting the
main process.
-max_event_secs is not being honered correctly. EventLoop was not
calculating the amount the hls clips to grab from live correctly.
chanaged it to properly calculate file count based on hls segment
size.
-updated the documentation as the current version nears stable
release.
-turns out the previous statment on the previous commit is
incorrect. it is every possible to overlap events. to
mitigate this, evtHist was added to shared_t to track
recently copied source vids and remove them from the
event queued to be written.
-removed the delay after motion was detected. it was not having
the desired effect and after more thought event overlap would
be impossible anyway.
-the test cameras are still picking up motion during the post
command. adjusted the after command delay to see if that
helps.
-reduced the DetectLoop heartbeat from 3 to 2 to better match
the record loop's cadence.
-the test cameras are picking up motion as post command is running.
added a delay increment to DetectLoop in hope to fix this.
-removed the upkeep log since it doesn't really provide any useful
information.
-adjusted the default motion score again.
-reduced the amount of image files DetectLoop needs from 3 to 2.
-added a dely to DetectLoop after a positive motion detection to
prevent motion event overlap.
-moved the 2 image diff pair compair to proper "end of array" in
DetectLoop.
-increased the size of the image stream so queded up events will
be able generate thumbnails properly.
-cleaned off a bunch of unused parameters in the code.
-adjusted the default motion sensitivity after real world
testing.
-added libfuse-dev to setup.sh since imagemagic needs that to
operate.
The Qt approach to grabbing frames from the live stream was also
a failure.
- decided to switch to a combination ffmpeg and imagemagic was
external commands to do motion detection. this approach
elimates the need for opencv altogeather so it was removed
from the project. system resource usage appears to be decent
and perhaps better than opencv.
I'm going to test a move away from opencv's videoio module.
Videoio simply refuses to open any video file even with
FFMPEG builtin. I tested old v2.2 code and even that failed
on a fresh install of ubuntu sever so this tells me an
update on opencv's side broke something.
This issue is not new and frankly I'm tired of chasing it.
I'm giving QT's QMediaPlayer a try to see how it works out.
Will still need opencv for the absdiff and threshold
functions, otherwise I would have dropped the API
altogeather.
Now that the app has QT::Multimedia, QT6 is now the minimum
version it will support. CMakeList.txt and the setup script
updated accordingly.
Got the app up to "not failing immediately" state.
However, for some reason DetectLoop is failing hard via opencv
being unable to open the stream clips.
I'll continue deep diving this. For now everything else works.
Added the much need code in Camera object to actual start all of
the threads.
Added multi instance support via the -d option.
Made the Loop object loop structure slot-signal compatible so
all objects using it can interupt the main loop to run other
slots.
Completely re-written the project to use the QT API. By using Qt,
I've open up use of useful tools like QCryptographicHash, QString,
QByteArray, QFile, etc.. In the future I could even make use of
slots/signals. The code is also in general much more readable and
thread management is by far much easier.
General operation of the app should be the same, this commit just
serves as a base for the migration over to QT.
