找不到ffmpeg或avconv - Python
我正在做一个验证码解译器，我需要使用ffmpeg，虽然没什么用。Windows 10用户。
第一次运行代码时警告：
C:\Users\user\AppData\Roaming\Python\Python310\site-packages\pydub\utils.py:170: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work
warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)然后，当我尝试运行脚本时，它需要ff探头，我得到了以下错误：
C:\Users\user\AppData\Roaming\Python\Python310\site-packages\pydub\utils.py:198: RuntimeWarning: Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work
warn("Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work", RuntimeWarning)

FileNotFoundError: [WinError 2] The system cannot find the file specified我试着正常下载它，编辑环境变量，将它们粘贴在与脚本相同的文件夹中，用pip安装，手动测试ffmpeg以查看它是否有效，实际上它将mkv转换为mp4，但是我的脚本无意运行。

正如您从错误消息中看到的那样，问题在于ffprobe而不是ffmpeg。
确保ffprobe.exe和ffmpeg.exe都在可执行路径中。
- 的一个选项是将
ffprobe.exe和ffmpeg.exe放在与D:\Scripts\captcha\脚本相同的文件夹中(在您的例子中是D:\Scripts\captcha\)， - 其他选项是将
ffprobe.exe和ffmpeg.exe文件夹添加到Windows路径中。
(将EXE文件放置在系统路径中的文件夹中也可能有效)。
调试Pydub源代码(pydub-0.25.1)：
代码在以下代码中失败：
hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
# no special security
None, None,
int(not close_fds),
creationflags,
env,
os.fspath(cwd) if cwd is not None else None,
startupinfo)其中args = 'ffprobe -of json -v info -show_format -show_streams test.mp3'
我们从以下地点到达：
info = mediainfo_json(orig_file, read_ahead_limit=read_ahead_limit)
发自：
prober = get_prober_name()
以下是get_prober_name方法的源代码：
def get_prober_name():
"""
Return probe application, either avconv or ffmpeg
"""
if which("avprobe"):
return "avprobe"
elif which("ffprobe"):
return "ffprobe"
else:
# should raise exception
warn("Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work", RuntimeWarning)
return "ffprobe"which方法在执行路径中查找命令(如果没有找到，则返回None )。
从Pydub源代码中可以看到，ffprobe.exe应该在执行路径中。
- 注记
对于设置FFmpeg路径，我们还可以应用如下内容：
进口pydub pydub.AudioSegment.converter = 'c:\FFmpeg\bin\ffmpeg.exe‘声音=c：\FFmpeg\bin\ffmpeg.exe
但FFprobe没有这样的选择。
