如何使用Python加入两个视频文件？ [英] How to join two video files using Python?

问题描述

这里我尝试将第一个和第二个30秒长的视频文件从path / connect.webm剪切到字符串out和out1。有用。但我需要做的是连接这两个字符串，并将其写入文件path / final.webm。所以我得到一个60秒长的视频文件final.webm在最后。但现在我只得到第一个30秒长的视频作为输出。请帮帮我。感谢很多提前。

Here I tried to cut first and second 30sec long video file from "path/connect.webm" to the strings out and out1. It works. But what I need to do is to concatenate these two strings and write that to a file "path/final.webm". So that I get a 60sec long video file "final.webm" at the end. But now i get first 30sec long video only as the output. Please help me. Thanks a lot in advance.

python中的代码：

Code in python:

import subprocess,os

fname = "/home/xincoz/test/final.webm"

fp = open(fname,'wb')

ffmpeg_command = ["ffmpeg", "-i", "/home/xincoz/test/connect.webm", "-acodec", "copy",   "-ss", "00:00:00", "-t", "00:00:30","-f", "webm", "pipe:1"]

p = subprocess.Popen(ffmpeg_command,stdout=subprocess.PIPE)

out, err = p.communicate()

ffmpeg_command1 = ["ffmpeg", "-i", "/home/xincoz/test/connect.webm", "-acodec", "copy",   "-ss", "00:00:31", "-t", "00:00:30","-f", "webm", "pipe:1"]

p1 = subprocess.Popen(ffmpeg_command1,stdout=subprocess.PIPE)

out1, err1 = p1.communicate()

string = out + out1

print len(out)

print len(out1)

print len(string)

fp.write(string)

fp.close()

请帮助我。 p>

此代码适用于我。感谢大家的帮助。非常感谢。

This code works for me. Thanks all for your great help. Thanks a lot.

import subprocess
ffmpeg_command1 = ["ffmpeg", "-i", "/home/xincoz/test/connect.webm", "-acodec", "copy", "-ss", "00:00:00", "-t", "00:00:30", "/home/xincoz/test/output1.webm"]
ffmpeg_command2 = ["ffmpeg", "-i", "/home/xincoz/test/connect.webm", "-acodec", "copy", "-ss", "00:00:30", "-t", "00:00:30", "/home/xincoz/test/output2.webm"]
ffmpeg_command3 = ["mencoder", "-forceidx", "-ovc", "copy", "-oac", "pcm", "-o", "/home/xincoz/test/output.webm", "/home/xincoz/test/output1.webm", "/home/xincoz/test/output2.webm"]


subprocess.call(ffmpeg_command1)
subprocess.call(ffmpeg_command2)
subprocess.Popen(ffmpeg_command3)
