    Codecs模块

    这篇文章主要介绍了python自然语言编码转换模块codecs介绍,codecs专门用作编码转换,通过它的接口是可以扩展到其他关于代码方面的转换,需要的朋友可以参考下。

    常用说法:

    decode->unicode(内部编码格式)

    encode->其他编码格式

    解码(decode)成内部编码格式unicode,编码(encode)成其他格式。


    python对多国语言的处理是支持的很好的,它可以处理现在任意编码的字符,这里深入的研究一下python对多种不同语言的处理。

    有一点需要清楚的是,当python要做编码转换的时候,会借助于内部的编码,转换过程是这样的:原有编码 -> 内部编码 -> 目的编码

    python的内部是使用unicode来处理的,但是unicode的使用需要考虑的是它的编码格式有两种,一是UCS-2,它一共有65536个码位,另一种是UCS-4,它有2147483648g个码位。对于这两种格式,python都是支持的,这个是在编译时通过--enable-unicode=ucs2--enable-unicode=ucs4来指定的。那么我们自己默认安装的python有的什么编码怎么来确定呢?有一个办法,就是通过sys.maxunicode的值来判断:

    import sys
    print sys.maxunicode

    如果输出的值为65535,那么就是UCS-2,如果输出是1114111就是UCS-4编码。我们要认识到一点:当一个字符串转换为内部编码后,它就不是str类型了!它是unicode类型:

    a = "风卷残云"
    print type(a)
    b = unicode(a, "gb2312")
    print type(b)

    输出:

    <type 'str'>
    < type 'unicode'>

    这个时候b可以方便的任意转换为其他编码,比如转换为utf-8:

    c = b.encode("utf-8")
    print c

    好了,该说说codecs模块了,它和我上面说的概念是密切相关的。codecs专门用作编码转换,当然,其实通过它的接口是可以扩展到其他关于代码方面的转换的,这个东西这里不涉及。

    # 创建gb2312编码器
    look  = codecs.lookup("gb2312")
    #
    创建utf-8编码器
    look2 = codecs.lookup("utf-8")

    a = "我爱北京天安门"

    print len(a), a
    #
    a编码为内部的unicode, 但为什么方法名为decode呢,我的理解是把gb2312的字符串解码为unicode
    b = look.decode(a)
    #
    返回的b[0]是数据,b[1]是长度,这个时候的类型是unicode
    print b[1], b[0], type(b[0])
    #
    把内部编码的unicode转换为gb2312编码的字符串,encode方法会返回一个字符串类型
    b2 = look.encode(b[0])
    #
    发现不一样的地方了吧?转换回来之后,字符串长度由14变为了7! 现在的返回的长度才是真正的字数,原来的是字节数
    print b2[1], b2[0], type(b2[0])

    上面的代码就是codecs的使用,是最常见的用法。另外还有一个问题就是,如果我们处理的文件里的字符编码是其他类型的呢?这个读取进行做处理也需要特殊的处理的。codecs也提供了方法.

    #-*- encoding: gb2312 -*-
    import codecs, sys

    # codecs提供的open方法来指定打开的文件的语言编码,它会在读取的时候自动转换为内部unicode
    bfile = codecs.open("dddd.txt", 'r', "big5")
    #bfile = open("dddd.txt", 'r')

    ss = bfile.read()
    bfile.close()
    #
    输出,这个时候看到的就是转换后的结果。如果使用语言内建的open函数来打开文件,这里看到的必定是乱码
    print ss, type(ss)

    上面这个处理big5的,可以去找段big5编码的文件试试。

    The codecs parameter is specified by RFC 6381. Specifically, see section 3.3 for the meaning of avc1 and mp4a values.

    In the case of avc1.4D401Eavc1 indicates H.264 video, and this is followed by a dot and three 2-digit hexadecimal numbers defined by the H.264 standard:

    1. profile_idc
    2. the byte containing the constraint_set flags (currently constraint_set0_flag through constraint_set5_flag, and the reserved_zero_2bits)
    3. level_idc

    Some examples:

    • avc1.42E01E: H.264 Constrained Baseline Profile Level 3
    • avc1.4D401E: H.264 Main Profile Level 3
    • avc1.64001E: H.264 High Profile Level 3

    These are also the second, third, and fourth bytes of the Sequence Parameter Set and the AVC Configuration Box in an MP4 file. You can dump these bytes using a program such as mp4filemp4file --dump movie.mp4. Look for the avcC (AVC Configuration) Box and the hexadecimal values for AVCProfileIndicationprofile_compatibility, and AVCLevelIndication.

    As for mp4a.40.2mp4a indicates MPEG-4 audio. It is followed by a dot and a hexadecimal ObjectTypeIndication (objectTypeId in mp4file output), which can be looked up on the MPEG4 registration site. If this hexadecimal value is 40 (ISO/IEC 14496-3 Audio), it is followed by another dot and an audio object type in decimal. These are listed in the ISO/IEC 14496-3 standard and onWikipedia, and correspond to the first 5 bits of the DecoderSpecificInfo (decSpecificInfo) (unless these bits equal 31, in which case add 32 to the next 6 bits). mp4a.40.2 indicates AAC LC audio, which is what is usually used with H.264 HTML5 video.

    For example, codecs="avc1.42E01E, mp4a.40.2" would be correct for the movie below:

    $ mp4file --dump movie.mp4
    ...
        type avcC (moov.trak.mdia.minf.stbl.stsd.avc1.avcC)  ◀━━ avc1
