Python

Question

我正在比较 wav 文件，这个脚本在我切换到 LMDE Betsy 之前工作正常。给我错误的函数是：

def already_valid (arg_wav):
    for w in wavs:
         size_arg = getsize(arg_wav.src_path)
         size_w = getsize(w.src_path)
         if 0 < size_w == size_arg and w.src_path != arg_wav.src_path:
             print arg_wav.src_path, "::", w.src_path
             if audiodiff.audio_equal(arg_wav.src_path, w.src_path):
                 return True
    return False

我的第一个想法是它试图打开同一个文件两次，但 w.src_path != arg_wav.src_path 应该考虑到这一点。我得到这个输出：

来自我的函数：

/home/will/Desktop/soundfiles/TITAN Recordings/6648/hold1_por.wav :: /home/will/Desktop/soundfiles/TITAN Recordings/6677/hold1_por.wav

回溯：

Traceback (most recent call last):
  File "call_diff.py", line 145, in <module>
    verified += handle_wav(p)
  File "call_diff.py", line 73, in handle_wav
    if already_valid(curr_wav):
  File "call_diff.py", line 96, in already_valid
    if audiodiff.audio_equal(arg_wav.src_path, w.src_path):
  File "/usr/local/lib/python2.7/dist-packages/audiodiff/__init__.py", line 51, in audio_equal
    return checksum(name1, ffmpeg_bin) == checksum(name2, ffmpeg_bin)
  File "/usr/local/lib/python2.7/dist-packages/audiodiff/__init__.py", line 86, in checksum
    stderr=subprocess.PIPE)
  File "/usr/lib/python2.7/subprocess.py", line 710, in __init__
    errread, errwrite)
  File "/usr/lib/python2.7/subprocess.py", line 1335, in _execute_child
    raise child_exception
OSError: [Errno 2] No such file or directory

奇怪的是它昨天在 Linux Mint 17.1 和 Windows 上运行 7. 这是一些奇怪的 Debian 约定吗我不知道知道关于？是的，我仔细检查并两个文件都存在于所描述的路径中。

如果你查看 audiodiff 的源代码，你会发现你需要安装 ffmpeg 并且可能将 ffmpeg 二进制文件的路径设置为 FFMPEG_BIN 环境变量.
