IF Input filename exists in Output folder, skip BUT ALSO SKIP in FOR 语句

Question

这是我拥有的长 ffmpeg 脚本的摘录：

• 在当前目录中创建视频文件的文本文件
• 使用 FOR 语句搜索文本文件
• 输出到子目录

我要添加的是，如果文件已经存在，不仅不通过脚本的 rest“处理”go，而且不处理已经存在的文件。 （换句话说：如果文件的副本已存在于 output 目录中，则跳过处理该文件，同时也跳过处理已识别的重复文件本身。）

dir *.mkv *.mp4 /A-D-H /B /S |findstr /R %Exclude-Final% /v /i>%TempFilePath%
Echo:   These are the folders being Excluded:           "!Exclude-AlltheseFolders!"
SET "FINALCOMMAND="

    SETlocal EnableExtensions DisableDelayedExpansion
        SET "FilesFound=0" & SET "FilesEncoded=0" & SET "output="
        for /F "delims=" %%I in (%TempFilePath%) do (
            ::ECHO ==!TIME!================Next File: %%I ========================
            SET "output=%drive%%%~pI%%~nxI" & SET "filename=%%~nxI" & SET /A FilesFound+=1
                SETlocal EnableExtensions EnableDelayedExpansion
                IF exist "%drive%%%~pIoutput\%%~nxI" (SET "Convert_Audio1=N") ELSE IF !output2! == 1 (SET "Convert_Audio1=N") ELSE SET "Convert_Audio1=Y"

    
rem    ===============================
rem    FFProbe.exe evaluation of %%I files
rem    ===============================
rem    below still under the FOR statement above: for /F "delims=" %%I in (%TempFilePath%) do (
rem    ------------------------------------------------------------

rem     -----------------------------
IF !ConvertCodecs! == 1 (
    SET /A count=5
    IF /I "!output!" == "%%I" (
        SET "output=%~dp0output\!filename!"
rem     ECHO This is OUTPUT-DIR "%~dp0output\"
        MKDIR "%~dp0output\"
    ) ELSE (
        MKDIR "%drive%%%~pI"
    )

ENDLOCAL
......
ENDLOCAL
ENDLOCAL
ENDLOCAL

```

我希望在通过 FFProbe.exe 处理以加快速度之前，在此处进行所有过滤。 我假设在第一个 IF 语句中我可以做一些事情，但是当有多个文件，甚至只有 2 + 1 个子文件夹时，它不能结转正确的变量，即这将跳过文件 1，处理文件 2，然后尝试处理 file3

编辑：这是完整代码。 您需要输入您想要的目标驱动器（即 C: 或 D: 等...）。 它将寻找具有 eac3、flac、dts、pcm、aac 或 ac3 的 mkv 和 mp4 以转换为 aac。 （将视频音频从一种格式批量转换为另一种格式）

Answer 1

我想我找到了答案（我已经内置了）。

在我设计的设置部分，在完整代码的顶部，在第二个 SetLocal 下， SET ^"Exclude-AlltheseFolders=#snapshot^"变量，我调整为SET ^"Exclude-AlltheseFolders=#snapshot,output^"

这随后用于设置 Exclude-Final 变量：

SET ^"Exclude-Final=/c:"\^<!Exclude-AlltheseFolders!\^>"^"
SET ^"Exclude-Final=!Exclude-Final:,=%delm1%!^"

然后在这里使用：

dir *.mkv *.mp4 /A-D-H /B /S |findstr /R %Exclude-Final% /v /i>%TempFilePath%
Echo:   These are the folders being Excluded:           "!Exclude-AlltheseFolders!"

所以现在作为一个总结，我现在排除了任何文件夹/文件“输出*文件名*”，如果正在处理的文件夹中存在文件，我将其设置为可能的 output，这是代码的下一个，它检查是否文件存在于当前目录中，然后创建输出*文件名*。

IF !ConvertCodecs! == 1 (
    SET /A count=5
    IF /I "!output!" == "%%I" (
        SET "output=%~dp0output\!filename!"
        SET /A count+=1
        MKDIR "%~dp0output\"
        ) ELSE (
        MKDIR "%drive%%%~pI"
        )
