TrueHD/AC3 and eac3to

[twsnnva]

Does anyone know how to extract the entire TrueHD/AC3 track from a bluray disc with eac3to? If I use the ac3 extension for the destination I get AC3 only, and if I use the .thd extension I get TrueHD only, which I cannot import into Tsmuxer. Thanks.

Not sure, but you can just use TSMuxer instead.

The last time I tried to demux a TrueHD track with tsMuxeR all it gave me was the AC3 core.

I tried it last night and I believe it gave me the entire TrueHD track. You can also pull just the core if you want. The 2 files I pulled were as such...

AC3 core 640kbs = ~600Mb
TrueHD ?Kbs = ~2.9Gb

Not sure if the TrueHD 2.9Gb had the AC3 core inside but since you can get both separately, I assume that's all you need...

Is there any way to fully decode TrueHD information and convert it into wav ???

Thanks for the replies everyone.

I'm trying to do the TrueHD/AC3 demuxing with eac3to because I am using a cygwin script to automate the process of demuxing with eac3to, muxing to bd with tsmuxer and making an iso with imgburn. I can demux every other type of audio, video, and pgs with eac3to. Right now if the script finds TrueHD I simply have eac3to convert it to PCM, but I would like to keep TrueHD instead since it's smaller.

To answer the questions:

QuadcoreHD,
tsmuxer can extract the TrueHD/AC3 "interweaved" stream, but for my purposes I want to do this with eac3to.

lithiumus,
Yes, eac3to can extract both the TrueHD and the AC3 stream, but I can't see how to extract them together. Unfortunately, it seems tsmuxer cannot import TrueHD unless it is interweaved with the AC3 stream, which is the dilemma.

If I could simply demux with tsmuxer and create an iso I would not need to mess with eac3to or my cygwin script at all. Unfortunately, I can not seem to get a bluray iso that will playback on Vista without "glitches" if I use tsmuxer for the initial de/muxing.
