示例1: verify
# 需要导入模块: from audiotools import AudioFile [as 别名]
# 或者: from audiotools.AudioFile import verify [as 别名]
def verify(self, progress=None):
"""verifies the current file for correctness
returns True if the file is okay
raises an InvalidFile with an error message if there is
some problem with the file"""
# Checking for a truncated Ogg stream typically involves
# verifying that the "end of stream" flag is set on the last
# Ogg page in the stream in the event that one or more whole
# pages is lost. But since the OpusFile decoder doesn't perform
# this check and doesn't provide any access to its internal
# Ogg decoder (unlike Vorbis), we'll perform that check externally.
#
# And since it's a fast check, we won't bother to update progress.
