-the live stream is now a part of the camera's main page.
-fixed symm links for the main page not being created on install.
-removed deprecated ffmpeg timeout option.
-copied hls.js as a local file so live streams will still work
without being connected to the internet.
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.
Completely reformed the internal workings of the application code. I
brought back multi-threaded functions so there is now 5 separate threads
for different tasks.
recLoop() - this function calls ffmpeg to begin recording footage from
the defined camera and stores the footage in hls format. It is designed
to keep running for as long as the application is running and if it does
stop for whatever reason, it will attempt to auto re-start.
upkeep() - this function does regular cleanup and enforcement of maxDays
maxLogSize and maxEvents without the need to stop recording or detecting
motion.
detectMo() - this function reads directly from recLoop's hls output and
list all footage that has motion in it. motion detection no longer has
to wait for the clip to finish recording thanks to the use of .ts
containers for the video clips. this makes the motion detection for less
cpu intensive now that it will now operate at the camera's fps (slower).
eventLoop() - this function reads the motion list from detectMo and
copies the footage pointed out by the list to an events folder, also in
hls format.
schLoop() - this function runs an optional user defined external command
every amount of seconds defined in sch_sec. this command temporary stops
motion detection without actually terminating the thread. It will also
not run the command at the scheduled time if motion was detected.
Benefits to this reform:
- far less cpu intensive operation
- multi-threaded architecture for better asynchronous operation
- it has support for live streaming now that hls is being used
- a buff_dir is no longer necessary
Fixed the default webroot directory to apache's correct webroot. Also
renamed separated outDir from webRoot and made webRoot changeable on the
config file.
Added logging the recorder and detection loops to help with debugging
and troubleshooting. Just like the video clips, max log lines were added
to control the size of the data being saved to storage.
Decided to switch using opencv's builtin pixel diff motion detection via
absdiff and thresh. Doing this should increase efficiency instead of
using the home brewed pixel loops and threads.
Added a web interface of sorts by having html files output along with
the video clips. These files are designed to link together with the
assumption that the output directory is a web root like /var/www/html
that apache2 uses. The interface is crude at best but at least allow
playback of recorded footage.
Added max_clips config variable that can limit the amount of motion
events that can recorded to storage on a single day.
