Hello, my security camera has basic motion detection in hardware, but
saves many false positive 2min motion clips continuously when the scene
lighting or other conditions keep changing. The Motion package allows to
re-analyze such static video sets for true motion presence. One can use
scripting options like /on_event_end/, /on_motion_detected/ etc, which
allow to invoke external scripts.
I'm not a coder, and want to ask if current Motion developer or some
experienced users can offer bash script examples for typical scenarios
of Motion use for static video analysis. I need to run Motion fast on a
loop through a large folder with monthly and daily subfolders storing
hundreds of 1080p 25fps HEVC 2min video clips from a security camera, to
identify video clips with true motion, and delete remaining false
positive videos. It might be possible to speedup video processing by
setting higher video FPS value than original, and adding a frame zone
mask where to look for motion.
Once true motion event is detected in a video file, its name should be
added to MotionDetectedList.txt, and the file moved to a MotionDetected
folder with its date&time added to the file name. Motion should then
start processing the next video until all are analyzed.
I tried a similar small Windows package VideoMotionDetect
<https://github.com/shuuryou/videomotiondetect> (
https://github.com/shuuryou/videomotiondetect ) based on OpenCVSharp
with embedded ffmpg to analyze near 800 continuous daily 720P 25fps 1min
AVI video clips from security camera for motion presence, and it took
about 30min to process such batch with high detection accuracy, with
near 10-15% of clip names with motion detected added to a text file.
Sadly, that app can't open HEVC 1080P videos from my another security
camera.
I'd really appreciate any help with this scripting task, or please
suggest an existing similar Linux or Windows app able to run such batch
motion detection task fast enough on a typical home PC. What clip
processing speed one would expect from Motion package in such scenario?
Thank you!

Motion can process offline files using netcam config option and file://
protocol.
You can check an example:
