如何使用Windows PowerShell启动ffprobe [英] How to start ffprobe with Windows PowerShell

问题描述

我正在使用Zeranoes FFmpeg Builds for Windows，我可以启动ff-prompt而不安装任何东西。但是如何使用Windows PowerShell启动 ff-prompt.bat ？我已经尝试了一些东西，如 Invoke-Expression 或更改 $ env：Path ，但似乎没有任何效果，因为我所得到的是消息

I am using Zeranoes FFmpeg Builds for Windows and I can start the ff-prompt without installing anything. But how do I start ff-prompt.bat with Windows PowerShell? I have tried a few things like Invoke-Expression or changing the $env:Path but nothing seems to work, because all I get is the message

C：\Users\Administrator> ECHO OFF

"C:\Users\Administrator>ECHO OFF

bin\ffmpeg.exe找不到。

bin\ffmpeg.exe could not be found."

甚至可以启动ff-prompt电源外壳？每个建议/解决方案都比较受欢迎。

Is it even possible to start ff-prompt with PowerShell? Every suggestion / solution is more than welcome.

我的目标是在这里有一个这样的解决方案：

My goal is to have a solution that works like this here: http://spreadys.wordpress.com/2012/12/03/ffprobe-and-windows-powershell/

但是我想为自己的所有剪辑自动执行，这就是为什么我需要启动ffprobe与powershell。

but I want to do that automatically for all my clips, thats why I need to start ffprobe with powershell.

TITLE FF Prompt

  ECHO bin\ffmpeg.exe could not be found.
  GOTO:error
)

CD bin || GOTO:error
PROMPT $G
CLS
ffmpeg -version
SET PATH=%CD%;%PATH%
ECHO.
ECHO For help run: ffmpeg -h

ECHO.
ECHO Current directory is now: "%CD%"
ECHO The bin directory has been added to PATH
ECHO.

CMD /F:ON /Q /K
GOTO:EOF

:error
  ECHO.
  ECHO Press any key to exit.
  PAUSE >nul
  GOTO:EOF

这次有点不同：

$env:Path = ';C:\Users\Administrator\bin\'
$title = "A_Day_for_Cake_and_Accidents"
Start-Process ff-prompt.bat -ArgumentList "ffprobe -show_streams -select_streams v -print_format xml -count_frames C:\Users\Administrator\Desktop\dcp_bearbeitet\$title\$title.mov > C:\Users\Administrator\Desktop\dcp_bearbeitet\$title\totalframes.xml"

这将创建一个名为totalframes.xml的文件，但没有必要的信息，我唯一得到的是：

This creates a file called "totalframes.xml" but without the needed information, the only thing I get is:

所以基本上控制台弹出，写这个标准文本，不使用我在 -Argument-List 中指出的命令。我不知道为什么忽略我的大部分命令，除了将所有内容写在XML文件中。

So basically the console pops up, writes this standard text and does not use my commands which I stated in -Argument-List . I do not have a clue why it is ignoring most of my commands, except for writing everything in a XML file.

推荐答案

你可以从PowerShell启动ff-prompt.bat，如下所示。首先，将工作目录设置为包含ff-prompt.bat的工作目录。 C：\users\administrator\ffmpeg。其次，键入以下内容，然后按Enter键： .\ff-prompt.bat 。我从Zeranoe下载的文件集进行了测试，CMD会话打开并显示如下：

You can launch ff-prompt.bat from PowerShell as follows. Firstly, set the working directory to that which contains ff-prompt.bat e.g. c:\users\administrator\ffmpeg. Secondly, type the following and press enter: .\ff-prompt.bat. I tested this with file set downloaded from Zeranoe and the CMD session opened and displayed as follows:
