Python Popen - env - ffmpeg crash [英] Python Popen - env - ffmpeg crash

问题描述

我试图在Windows 7（python 2.7）上运行ffmpeg命令，它在命令行上运行正常，但是我的中的 env Popen 不工作。
这是工作命令行：

  SET FFREPORT = level = 48：file = C\：\ \temp\\TESTFFMPEGOUTPUT.txt&&& C：\Temp\ffmpeg\ffmpeg.exe -iI：\somefolder\testInput.movI：\somefolder\testOutput.mov
  

这里是我目前的python代码：

  ffreport =level = 48：file = {}。format（self.logFilePath）+&& 
 startupinfo = subprocess.STARTUPINFO（）
 startupinfo.dwFlags | = subprocess.STARTF_USESHOWWINDOW 
 self.process1 = Popen（command，startupinfo = startupinfo，shell = False，env = {'SET FFREPORT '：ffreport}）
  

这导致Windows报告ffmpeg已停止工作
不确定如何修复。

解决方案

  command = rC：\Temp\\ \\ffmpeg\ffmpeg.exe -i我：\somefolder\testInput.mov我：\somefolder\testOutput.mov
 
 self.process1 = Popen（
 shlex。 split（命令），shell = False，
 env = dict（FFREPORT =level = 48：file = C\：\\temp\\TESTFFMPEGOUTPUT.txt））
  

I am trying to run an ffmpeg command on Windows 7 (python 2.7) which runs on command line just fine, but the env of my Popen is not working. Here is the working command line:

SET FFREPORT=level=48:file=C\:\\temp\\TESTFFMPEGOUTPUT.txt && C:\Temp\ffmpeg\ffmpeg.exe -i "I:\somefolder\testInput.mov" "I:\somefolder\testOutput.mov"

And here is my current python code:

ffreport = "level=48:file={}".format(self.logFilePath) + " && "
startupinfo = subprocess.STARTUPINFO()
startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
self.process1 = Popen(command, startupinfo=startupinfo, shell=False, env={'SET FFREPORT':ffreport})

This results in windows reporting "ffmpeg has stopped working". Not sure how to fix.

解决方案

command = r"C:\Temp\ffmpeg\ffmpeg.exe -i I:\somefolder\testInput.mov I:\somefolder\testOutput.mov"

self.process1 = Popen(
        shlex.split(command), shell=False, 
        env=dict(FFREPORT="level=48:file=C\:\\temp\\TESTFFMPEGOUTPUT.txt"))
