爲什麼第二個電話不能批量工作？

Question

我有以下批處理腳本，多數民衆贊成從另一個使用

cmd /c 1getthumbs @file > log.txt 

內容1getthumbs稱爲是：

set initFile=%1 
echo.%initFile% 
set out=%initFile:.mts=-a.jpg% 
rem echo.%out% 

ffmpeg32 -ss 00:00:30 -i "C:\Users\s\Desktop\social\\%1" -frames:v 1 
"C:\Users\s\Desktop\social\thumbs\\%out%" 

set out=%initFile:.mts=-b.jpg% 
echo.%out% 

ffmpeg32 -ss 00:01:00 -i "C:\Users\s\Desktop\social\\%1" -frames:v 1 
"C:\Users\s\Desktop\social\thumbs\%out%" 

下執行第一ffmpeg32而不是第二ffmpeg32 任何想法，爲什麼？

更新與log.txt的內容時，我測試了：

C:\Program Files\ffmpeg>set initFile="00178.MTS" 

C:\Program Files\ffmpeg>echo."00178.MTS" 
"00178.MTS" 

C:\Program Files\ffmpeg>set out="00178-a.jpg" 

C:\Program Files\ffmpeg>rem echo."00178-a.jpg" 

C:\Program Files\ffmpeg>ffmpeg32 -ss 00:00:30 -i "C:\Users\s\Desktop\social\\"00178.MTS"" -frames:v 1 "C:\Users\s\Desktop\social\thumbs\\"00178-a.jpg"" 

這裏是輸出，當我執行它調用1getthumbs.bat

C:\Program Files\ffmpeg>cmd /c 1getthumbs "00178.MTS" > log.txt

試試這個批處理文件：它可以解決一些引用和斜線問題。
如果ffmpeg32是一個批處理文件，那麼你將需要使用call ffmpeg32

set "initFile=%~1" 
echo."%initFile%" 
set "out=%initFile:.mts=-a.jpg%" 
rem echo."%out%" 

ffmpeg32 -ss 00:00:30 -i "C:\Users\s\Desktop\social\%initFile%" -frames:v 1 "C:\Users\s\Desktop\social\thumbs\%out%" 

set "out=%initFile:.mts=-b.jpg%" 
echo."%out%" 

ffmpeg32 -ss 00:01:00 -i "C:\Users\s\Desktop\social\%initFile%" -frames:v 1 "C:\Users\s\Desktop\social\thumbs\%out%"
