我正在用python播放mp4文件,但视频声音没有出来,我搜索了一段时间以查看是否可以播放声音,但找不到任何东西。有谁知道如何播放声音?
我张贴显示视频的代码:
import cv2
import numpy as np
# Create a VideoCapture object and read from input file
# If the input is the camera, pass 0 instead of the video file name
cap = cv2.VideoCapture('video.mp4')
# Check if camera opened successfully
#if (cap.isOpened()== False):
# print("Error opening video stream or file")
# Read until video is completed
while(cap.isOpened()):
# Capture frame-by-frame
ret, frame = cap.read()
if ret == True:
# Display the resulting frame
cv2.imshow('Frame',frame)
# Press Q on keyboard to exit
if cv2.waitKey(25) & 0xFF == ord('q'):
break
# Break the loop
else:
break
# When everything done, release the video capture object
cap.release()
# Closes all the frames
cv2.destroyAllWindows()
cv2不允许播放声音似乎没有用。顺便说一下,我正在使用Python 3。谢谢。
ANSWER: OpenCV is a computer-vision library. It does not support audio. If you want to play sound, you can try ffpyplayer. – Thanks to >>> yushulx
最佳答案
您可以使用Pyglet播放视频及其音频。
希望这可以帮助...
import pyglet
vid_path='vid1.mp4' # Name of the video
window=pyglet.window.Window()
player = pyglet.media.Player()
source = pyglet.media.StreamingSource()
MediaLoad = pyglet.media.load(vid_path)
player.queue(MediaLoad)
player.play()
@window.event
def on_draw():
if player.source and player.source.video_format:
player.get_texture().blit(50,50)
pyglet.app.run()
