  • How to join two video files using Python ?

    1er juillet 2013, par rash

    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.

    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()

    Please help me.
