        偶然看到张国荣的《东邪西毒》.发现居然没看过.然后看到有评论说.很难看懂之类的.所以就打算下载来看下.当时用的是手机.就用百度视频离线了.打算回家后导出到电脑上看看的.但回家后导出来才发现根本没办法合并啊.一堆毫无规律的BDV分段文件.百度一番后.总算找到解决办法了.

        以下是作者原文:

    -------------------------------------------------------------------------------

    百度影音的bdv格式又有变化。

    此次存在2种bdv格式。

    格式1:每个文件夹内就一个bdv文件,文件合并后改名avi即可。

    格式2:每个文件夹内一个bdv文件作为索引,其他附加guid的文件作为数据。

    例如:

    #EXTM3U
    #EXT-X-TARGETDURATION:30
    #EXT-X-MEDIA-SEQUENCE:0
    #EXTINF:10,

     

    所以python脚本有改。

    该脚本修正了单个文件在批处理过程名称。

        之前也是看不明白上面的代码怎么用.一番折腾后.总算成功了.如果有看不懂的朋友.可以下载我弄好的压缩文件.解压出来后.把离线的那一大堆BDV分段文件放到"yield"文件夹里面.然后再运行"mergefilm.py".(我电脑装的是2.6版本的Python.用IDLE打开后.再按F5就可以运行脚本了.)完成后就可以看到已经合并完成的文件了.但前提是电脑上必须先装上"Python".才可以运行脚本.

        今天去作者博客看了下.他已经更新了.在此顺便贴一下.方便各位来访者.

        以下是作者原文:

    -------------------------------------------------------------------------------

    合并百度影音的离线数据 with python 2.3 格式更新

    很久没有更新了。

    这次新增支持四种格式的解析。

    filelist

    slicelist

    download.cfg

    third_party_download.cfg

    还是2个文件。替换之前版本即可。

    初步测试正常,但时间轴不对。
