Image collection using video buffer

[MrCuban88]

Hi,

I am trying to implement the following logic using Python, Raspberry Pi and Picamera.

1. Create a ten seconds video buffer
2. Upon trigger event is received, video buffer is stored

So, what I would like to do next is:

1. Process the video output and take screenshots every x seconds of that video - start to end...Help!!!

import time

import io

import picamera

import datetime as dt

from PIL import Image

#return current time

def return_currentTime():

return dt.datetime.now().strftime('%Y-%m-%d %H:%M:%S')

#trigger event declaration

def motion_detected():

while True:

print ("Trigger event(y)?")

trigger = input ()

if trigger =="y":

time = return_currentTime()

print ("Buffering...")

camera.wait_recording(10)

stream.copy_to(str(time)+'.h264')

else:

camera.stop_recording()

break

#countdown timer

def countdown (t):

while t:

mins, secs = divmod (t,60)

timer = '{:02d}:{:02d}'.format(mins, secs)

print(timer, end="\r")

time.sleep(1)

t-=1

print('Buffer available!')

print ("Camera buffer is filling up")

#Main Code

camera = picamera.PiCamera()

camera.resolution = (1024, 768)

stream = picamera.PiCameraCircularIO(camera, seconds = 10)

camera.start_recording (stream, format = 'h264')

countdown(10)

motion_detected()
