請各前輩指導一下哪邊有誤
找到 "VIDENC" 後，擷取 最左邊 "=" 右邊 的完整字串
"-c:v libx264 -profile:v high -preset veryslow -x264opts crf=18:ref=4:bframes=5"
cd/d "%~dp0"

試試看@echo o...(恕刪)
非常感謝
去查了一下 findstr 用法，總算解決了
但還是有兩個問題
1.
FOR %variable IN (set) DO 命令 [command-parameters]
在 do (...) 裡面寫 if、set 好像很容易錯誤，這是BUG嗎? 改成下面這樣就沒問題了。
@echo off
set keyword=VIDENC
for /f "delims=" %%a in ('type config.ini^|findstr / "\<%keyword%="') do (
set za=%%a
)
set znew=%za:~7%
set z
pause
2.
config.ini
--------------------------------
#Settings
ITEM1_NAME=ITEM1_VALUE
ITEM2_NAME=ITEM2_VALUE
ITEM3_NAME=ITEM3_VALUE
--------------------------------
ITEM_NAME不一定都是6個字元，ITEM_VALUE裡面可能也包含 "="
下面的寫法好像太複雜，有沒有比較簡單的方式可以分割字串
@echo off & cd/d "%~dp0"
:readconfig
set keyword=VIDENC
for /f "eol=# delims=" %%a in ('type config.ini^|findstr / "\<%keyword%="') do (
call :split "%%a" title params
)
:break
echo title: %title%
echo params: %params%
pause
:split
set str=%~1
set str1=
set str2=
set /a length=0
:loop
if defined str (
set str=%str:~1%
set str1=%str1%%str:~0,1%
set str2=%str:~2%
set /a length+=1
if not "%str:~1,1%"=="=" goto loop
)
set %2=%str1%
set %3=%str2%
goto :eof

首先，先說聲抱歉，這是一個 BUG，一個人的 BUG，其實是我漏打了一個 I
，這是 findstr 的參數，用於尋找時，不區分大小寫for /f "delims=" %%a in ('type config.ini^|findstr /i "%keyword%"') do (

readconfig2 看不出哪裡有問題，這是鬼打牆?
