v3.0.t11
-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.

@ -4,22 +4,18 @@ Motion Watch is a video surveillance application that monitors the video feeds
|
|||
of an IP camera and records only footage that contains motion. The main
|
||||
advantage of this is reduced storage requirements as opposed to continuous
|
||||
recording because only video footage of interest is recorded to storage.
|
||||
The entire app is designed to operate on just one camera but multiple instances
|
||||
of this app can be used to operate multiple cameras.

||||

||||
### Usage ###
|

|

```
|

Usage: mow <argument>
|
||||
|
||||
-h : display usage information about this application.
|
||||
-c : path to the config file(s).
|
||||
-v : display the current version.
|
||||
|
||||
note: multiple -c config files can be passed, reading from left
|
||||
to right. any conflicting values between the files will
|
||||
have the latest value from the latest file overwrite the
|
||||
the earliest.
|
||||
-h : display usage information about this application.
|
||||
-c : path to the config file used to run a single camera instance.
|
||||
-d : path to a directory that can contain multiple config files.
|
||||
each file found in the directory will be used to run a
|
||||
camera instance.

||||
-v : display the current version.
