python - 在 WIndows 中为 Python 安装 FFMPEG

Question

我正在尝试使用 this python 视频转换器，我什至无法运行测试。我在手册中读到我必须单独安装 FFMPEG，所以我做了(我在 C:\中创建了文件夹，环境变量“路径”并对其进行了测试并起作用)但仍然不起作用。

当我运行命令时:

python setup.py test

我明白了:

Traceback (most recent call last):
  File "setup.py", line 51, in <module>
    packages=['converter'],
  File "C:\Python27\lib\distutils\core.py", line 151, in setup
    dist.run_commands()
  File "C:\Python27\lib\distutils\dist.py", line 953, in run_commands
    self.run_command(cmd)
  File "C:\Python27\lib\distutils\dist.py", line 972, in run_command
    cmd_obj.run()
  File "setup.py", line 20, in run
    raise Exception('tests failed')
Exception: tests failed

当我运行这个示例代码时:

from converter import Converter
c = Converter()

info = c.probe('test1.ogg')

conv = c.convert('test1.ogg', '/tmp/output.mkv', {
    'format': 'mkv',
    'audio': {
        'codec': 'mp3',
        'samplerate': 11025,
        'channels': 2
    },
    'video': {
        'codec': 'h264',
        'width': 720,
        'height': 400,
        'fps': 15
    }})

for timecode in conv:
    print "Converting (%f) ...\r" % timecode

我明白了:

Traceback (most recent call last):
  File "C:\Users\USER\worspace_pyth\cosa\prueba1.py", line 3, in <module>
    c=Converter()
  File "C:\Python27\converter\__init__.py", line 27, in __init__
    ffprobe_path=ffprobe_path)
  File "C:\Python27\converter\ffmpeg.py", line 345, in __init__
    raise FFMpegError("ffmpeg binary not found: " + self.ffmpeg_path)
converter.ffmpeg.FFMpegError: ffmpeg binary not found: ffmpeg

我不明白我还需要做什么才能让它工作。感谢您的帮助。

我能够按照此处找到的说明工作。至少在我的命令提示符中键入 ffmpeg -version 返回了一个结果。
