[英]How to split a video in parts using Python?
我需要将任意大小的视频文件拆分为最大大小不超过 75 MB 的各个部分。 我找到了这段代码,但它不起作用:
import cv
capture = cv.CaptureFromFile(filename)
while Condition1:
# Need a frame to get the output video dimensions
frame = cv.RetrieveFrame(capture) # Will return None if there are no frames
# New video file
video_out = cv.CreateVideoWriter(output_filenameX, CV_FOURCC('M','J','P','G'), capture.fps, frame.size(), 1)
# Write the frames
cv.WriteFrame(video_out, frame)
while Condition2:
frame = cv.RetrieveFrame(capture) # Will return None if there are no frames
cv.WriteFrame(video_out, frame)
这是我刚刚使用 MoviePy 创建的脚本。 但不是除以字节大小,而是除以视频长度。 因此,如果您将divide_into_count
设置为 5,并且您有一个长度为 22 分钟的视频,那么您将获得长度为 5、5、5、5、2 分钟的视频。
from moviepy.editor import VideoFileClip
from time import sleep
full_video = "full.mp4"
current_duration = VideoFileClip(full_video).duration
divide_into_count = 5
single_duration = current_duration/divide_into_count
current_video = f"{current_duration}.mp4"
while current_duration > single_duration:
clip = VideoFileClip(full_video).subclip(current_duration-single_duration, current_duration)
current_duration -= single_duration
current_video = f"{current_duration}.mp4"
clip.to_videofile(current_video, codec="libx264", temp_audiofile='temp-audio.m4a', remove_temp=True, audio_codec='aac')
print("-----------------###-----------------")
