我使用EAC3提取均为噪音。然后尝试使用DGAVCINDEX分离，分离结果是eac3格式的音频，时长竟然是 05:42:28，原盘长度是2个小时的。求助一下有没有人晓得这是怎么回事~

附eac3to的提取log文件
eac3to v3.24

用tsmuxer提取

LZ 我也遇到一样的问题了， tsmuxer 和MeGUI 都会变长，原视频长度是173分钟，提出出来之后 有210分钟！ 软件版本检查过了都是最新版哦！

楼主是不是只提取到一个，而本身是N个文件。我也遇到过tsMuxerGUI从BDMV提取出来的音频竟然是N个文件，最后只好用其他软件直接抽取成MKA，转换也软件甚至有的都会转换出一堆文件来，而有些可以直接转成一个FLAC！
