无法识别的选项 'c copy'
Unrecognized option 'c copy'
作为学习过程和创建方便工具的一部分,我一直在编写脚本。我正在尝试遍历视频文件列表以提取列表中每个视频的特定部分。通过查看示例脚本和 ffmpeg 文档,我终于想出了这个:
import os
import sys
import subprocess as sp
from moviepy.tools import subprocess_call
def ffmpeg_extract_pandomim_subclip():
with open('videolist.txt') as f:
lines = f.readlines()
lines = [x.strip() for x in lines]
for video in lines:
name, ext = os.path.splitext(video)
targetname = "%s-pandomim%s" % (name, ext)
t1 = "00:10:00"
t2 = "00:15:00"
cmd = ["ffmpeg",
"-i", "%s%s" % (name, ext),
"-ss", t1,
"-to", t2, "-c copy", targetname]
subprocess_call(cmd)
ffmpeg_extract_pandomim_subclip()
我知道这不是理想的方法:我创建了一个 videolist.txt 并逐行列出了该 txt 文件中的所有视频文件名,(T1-1.mp4,T1- 2.mp4,... ) 与 python 脚本共享同一个文件夹 "new 1.py" 和实际视频 T1-1.mp4, T1-2.mp4,...
我得到的错误真的让我很困惑,因为当我从 cmd 使用 -c copy 时它工作得很好。
完整的错误是:

我正在使用 Pycharm,如果我删除 -c copy 部分,它可以工作,但过程很慢......使用 -c copy,速度要快得多。
感谢你花时间和精力帮助我!
这将是由于 subprocess.call
实际调用命令的方式;您不能将所有命令压缩成一个字符串,它们应该完全展开。
要解决这个问题,只需将其扩展为两个参数即可
[ ..., "-c", "copy", ... ]
