Extracting TruHD stream from a BR


Recommended Posts

As the title says I'm trying to extract the TruHD stream from a Blu-Ray I've ripped on my hard drive, Akira which is encoded in 24bits/192Khz, to re-encode them in DTS HDMA because of some stupid problem of downmixing between my PS3 and my amp. But I'm running into a problem : I'm using eac3to, everything seems to run fine appart from a warning stating that my files will exceed the 4Gb limit and I may run into some problems when trying to playing the resulting wavs file into some players. The catch is that the extracted files are running for 11 seconds when the movie runs for more than 2 hours and, of course, I've got no sound in those wav files.

Does anyone knows where I'm making a mistake or forgetting something ?

1) what programs are you using to decrypt

2) what commands are you using

I use AnyDVDHD with eac3to, i separate the audio and video, so normally i end up with a .h264 and a .truehd or dtshd file, then i work on those. coring the DTS is easy, you could try converting the .truehd to .flac using

eac3to input.truehd output.flac

and then uncompressing the .flac file(s), bit of a mess about, if it were myself i would just encode the truehd file to a 640kbps AC3 file

eac3to input.thd output.ac3

unless you have a HD reciever then i can understand your predicament :shifty:
