*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()
