【1】最新版更新到Eac3to V3.29，更新时间是2015年3月25日。更新内容：
* added libDcaDec decoder for DTS decoding, new default for 7.x tracks【直接解码DTSHD，貌似最新版的lavfilters也加入libDcaDec了）
* fixed: #086: left/right eye information was inverted in some 3D Blu-Rays
* fixed: #263: decoding TrueHD Atmos with active dialnorm information failed
* fixed: #264: using "-float32 -normalize" didn't work in all cases.

为啥我用不了呢？下载了Eac3to v3.29版后双击打开出现了DOS界面后闪了一下就没了。

DTS Master Audio, 7.1 channels, 24 bits, 48kHz
(core: DTS, 5.1 channels, 1509k
bp
s, 48kHz)
dts, 48000, 7.1
Decoding with libDcaDec DTS Decoder...
Encoding FLAC with libFlac...
Creating file "D:\S.flac"...
The original audio track has a constant bit depth of 24 bits.
eac3to processing took 20 minutes, 5 seconds.
Done.
用Eac3to V3.29可以不需要依赖于Arcsoft dtsdecoder而直接解码DTSHD.
