我尝试使用Python中的mp4
将目录test
中的许多output.mp4
文件合并为一个ffmpeg
。
path = '/Users/x/Documents/test'
import os
for filename in os.listdir(path):
if filename.endswith(".mp4"):
print(filename)
输出:
4. 04-unix,minix,Linux.mp4
6. 05-Linux.mp4
7. 06-ls.mp4
5. 04-unix.mp4
9. 08-command.mp4
1. 01-intro.mp4
3. 03-os.mp4
8. 07-minux.mp4
2. 02-os.mp4
10. 09-help.mp4
我从以下参考资料中尝试了以下解决方案:ffmpy concatenate multiple files with a file list
import os
import subprocess
import time
base_dir = "/path/to/the/files"
video_files = "video_list.txt"
output_file = "output.avi"
# where to seek the files
file_list = open(video_files, "w")
# remove prior output
try:
os.remove(output_file)
except OSError:
pass
# scan for the video files
start = time.time()
for root, dirs, files in os.walk(base_dir):
for video in files:
if video.endswith(".avi"):
file_list.write("file './%s'\n" % video)
file_list.close()
# merge the video files
cmd = ["ffmpeg",
"-f",
"concat",
"-safe",
"0",
"-loglevel",
"quiet",
"-i",
"%s" % video_files,
"-c",
"copy",
"%s" % output_file
]
p = subprocess.Popen(cmd, stdin=subprocess.PIPE)
fout = p.stdin
fout.close()
p.wait()
print(p.returncode)
if p.returncode != 0:
raise subprocess.CalledProcessError(p.returncode, cmd)
end = time.time()
print("Merging the files took", end - start, "seconds.")
我已经合并它们并得到一个output.mp4
,但是文件没有按第一个按点分隔的数字(1, 2, 3, ...
)进行合并:我可以用filename.split(".")[0]
来获得:< / p>
1. 01-intro.mp4
2. 02-os.mp4
3. 03-os.mp4
4. 04-unix,minix,Linux.mp4
5. 04-unix.mp4
6. 05-Linux.mp4
7. 06-ls.mp4
8. 07-minux.mp4
9. 08-command.mp4
10. 09-help.mp4
如何在Python中正确,简洁地合并它们?谢谢。

import glob
import os
def concatenate():
global stringa
stringa = "ffmpeg -i \"concat:"
elenco_video = glob.glob("*.mp4")
elenco_file_temp = []
for f in elenco_video:
file = "temp" + str(elenco_video.index(f) + 1) + ".ts"
os.system("ffmpeg -i " + f + " -c copy -bsf:v h264_mp4toannexb -f mpegts " + file)
elenco_file_temp.append(file)
print(elenco_file_temp)
for f in elenco_file_temp:
stringa += f
if elenco_file_temp.index(f) != len(elenco_file_temp)-1:
stringa += "|"
else:
stringa += "\" -c copy -bsf:a aac_adtstoasc output.mp4"
print(stringa)
os.system(stringa)
这将在工作目录中创建一个名为 output.mp4
的串联视频文件,

此解决方案有效:
from moviepy.editor import *
import os
from natsort import natsorted
L =[]
for root, dirs, files in os.walk("/path/to/the/files"):
#files.sort()
files = natsorted(files)
for file in files:
if os.path.splitext(file)[1] == '.mp4':
filePath = os.path.join(root, file)
video = VideoFileClip(filePath)
L.append(video)
final_clip = concatenate_videoclips(L)
final_clip.to_videofile("output.mp4", fps=24, remove_temp=False)
