本文介绍了百度影音中BDV格式的变化及两种不同格式的特点。提供了Python脚本以支持不同版本的BDV文件处理，包括读取索引文件并合并为单一视频文件的功能。

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。

该脚本增加单个文件read_bdv_index_V3和bdv新格式支持read_bdv_index_V4。
