Live Streaming Video through WebCam

Hello Everyone, I'm using the Live Streaming Video through WebCam. It's storing in .avi format. When i'm playing the Video. I'm not getting the audio of that video. I hope that opencv does not provide the audio features. Kindly let me know if you have any idea. Thanks,

Please find the below code:---------------

import os.path

import numpy as np

import cv2, time

import random

def change_res(cap, width, height):

cap.set(3, width)

cap.set(4, height)

#Standard Video Dimensions Sizes

STD_DIMENSIONS = {

'480p': (640, 480),

'720p': (1280, 720),

'1080p': (1920, 1080),

'4k': (3840, 2160),

}

VIDEO_TYPE = {

'avi':cv2.VideoWriter_fourcc(*'XVID'),

'mp4':cv2.VideoWriter_fourcc(*'XVID'),

}

def get_video_type(filename):

ext = os.path.splitext(filename),

if ext in VIDEO_TYPE:

return VIDEO_TYPE[ext]

return VIDEO_TYPE['avi']

def get_dims(cap, res='480p'):

width, height = STD_DIMENSIONS['480p']

if res in STD_DIMENSIONS:

width, height = STD_DIMENSIONS[res]

change_res(cap, width, height)

return width, height

#--------------START LIVE VIDEO----------#

random_id = random.randint(10000,99999)

livevideo_name = str('livevideo_'+str(random_id)+'.avi')

frames_per_second = 20.0  #..Frame Per Second

my_res = '480p'  #..Frame Size

# Capture video from camera

livevideos = '/livevideos/'+livevideo_name

cap = cv2.VideoCapture(-1)

dims = get_dims(cap, res=my_res)

video_type_cv2 = get_video_type(livevideos) 

# Define the codec and create VideoWriter object

fourcc = cv2.VideoWriter_fourcc(*'XVID') # Be sure to use the lower case

out = cv2.VideoWriter(livevideos, video_type_cv2, frames_per_second, dims)

while(True):

ret, frame = cap.read()

if ret==True:

frame = cv2.flip(frame,1)

# Write the frame into the file

out.write(frame)

cv2.imshow('frame',frame)

if cv2.waitKey(1) & 0xFF == ord('q'):

break

else:

break

# When everything done, release the video capture and video write objects

cap.release()

out.release()

# Closes all the frames

cv2.destroyAllWindows()
