我使用Python的cv2模块将jpg帧合并成视频,但是我无法添加音频。在Python中是否有可能不使用ffmpeg来给视频添加音频?
附言:对我的英语表达不好,抱歉。
import cv2
import numpy as np
#ffpyplayer for playing audio
from ffpyplayer.player import MediaPlayer
video_path="../L1/images/Godwin.mp4"
def PlayVideo(video_path):
video=cv2.VideoCapture(video_path)
player = MediaPlayer(video_path)
while True:
grabbed, frame=video.read()
audio_frame, val = player.get_frame()
if not grabbed:
print("End of video")
break
if cv2.waitKey(28) & 0xFF == ord("q"):
break
cv2.imshow("Video", frame)
if val != 'eof' and audio_frame is not None:
#audio
img, t = audio_frame
video.release()
cv2.destroyAllWindows()
PlayVideo(video_path)
这个样例代码可以工作,但是你需要根据视频的速度来调整cv2.waitKey(28)。
img
和 t

from moviepy.editor import *
from pafy import pafy
if __name__ == '__main__':
video = pafy.new('https://www.youtube.com/watch?v=K_IR90FthXQ')
stream = video.getbest(preftype='mp4')
video = VideoFileClip(stream.url)
audio = video.audio
for t, video_frame in video.iter_frames(with_times=True):
audio_frame = audio.get_frame(t)
print(audio_frame)
print(video_frame)
import pygame
pygame.mixer.init()
pygame.mixer.music.load(
'c:Your_file')
pygame.mixer.music.play()
while True:
pygame.time.Clock().tick()
#used to show that you can do other stuff while playing audio
print("hi")
