I have a python project that reads frames from a ip_camera and writes it in a .avi video, but its size is becomes too large for example a 1 min record has a size about 200 MB. I want to reduce the video bitrate to reduce the size at same time that the video is being written. I tried so many ways but none of them worked out. Here is my code:
import os
from threading import Thread
import cv2
class VideoCamera(object):
def __init__(self, src=''):
self.capture = cv2.VideoCapture(src)
self.status = False
self.frame = self.capture.read()
self.frame_width = int(self.capture.get(3))
self.frame_height = int(self.capture.get(4))
self.codec = cv2.VideoWriter_fourcc(*'MJPG')
self.video_name = "video.avi"
self.output_video = cv2.VideoWriter(
self.video_name,
self.codec, 5,
(self.frame_width, self.frame_height))
self.stream_thread = Thread(target=self.update, args=())
self.record_thread = Thread(target=self.record, args=())
self.stream_thread.daemon = True
self.stream_thread.start()
def update(self):
while True:
if self.capture.isOpened():
(self.status, self.frame) = self.capture.read()
def record(self):
print('schedule')
while True:
print('stop recording')
self.capture.release()
self.output_video.release()
cv2.destroyAllWindows()
break
try:
if self.status:
self.output_video.write(self.frame)
except AttributeError:
pass
def start_recording(self):
self.record_thread.start()
if __name__ == '__main__':
cam = VideoCamera('rtsp://<username>:<password>@<camera_ip>:<camera_port>')
cam.start_recording()
