我一直在研究腳本作爲學習過程和創建方便工具的一部分。我試圖循環播放列表中的視頻文件來提取每個視頻的某個部分。通過查看示例腳本和ffmpeg的文檔,我終於想出了這一點:無法識別的選項'c副本'
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()
我知道這是不是這樣做的理想方式:我創建了一個videolist.txt並在TXT列出的所有視頻文件名文件,逐行,(T1-1.mp4,T1-2.mp4,...)與python腳本「new 1.py」和實際的視頻T1-1.mp4共享相同的文件夾, T1-2.mp4,...
這個錯誤讓我很困惑,因爲當我從cmd使用-c複製時,它工作得很好。
完整的錯誤是:

我使用Pycharm,如果我刪除它的工作拷貝-c部分,但是這個過程是緩慢的...用-c副本,它的速度要快得多。
我很感謝您的時間和精力來幫助我!
你可以嘗試擴大這兩個單獨的參數,他們是:'「-c」,「複製」'? –
太棒了!非常感謝克拉克先生。我會記住這些細節 –
