Generally, would you enalbe phase shift when reencoding to dts es matrix/discrete 6.1 ? Or can it be a Problem when you reencode those dts encodes with phase shift? |

Then if Ls and Rs are similar is better apply the phase shift but if Ls Rs was generated previously with some phase shift maybe a new phase shift can be worse. In a conversion DTS-ES -> wav -> some changes -> DTS-ES isn't recommended apply phase shift (must be already phase shifted, was extracted to Ls Rs because are different).

I'm trying to extract AC3 from a TrueHD/AC3 track in a blu-ray m2ts. Can someone please tell me what I'm doing wrong?
Here's what I do and what it says: Code:
W:\STREAM>eac3to 00010.m2ts trackno:1 track1.ac3 M2TS, 1 video track, 3 audio tracks, 8 subtitle tracks, 2:06::02 1: Chapters, 15 chapters 2: h264/AVC, 1080p24 /1.001 (16:9) 3: TrueHD/AC3, English, 5.1 channels, 48khz, dialnorm: -27dB 4: AC3, French, 5.1 channels, 640kbps, 48khz, dialnorm: -27dB 5: AC3, Spanish, 5.1 channels, 640kbps, 48khz, dialnorm: -27dB 6: Subtitle (PGS), English 7: Subtitle (PGS), English 8: Subtitle (PGS), French 9: Subtitle (PGS), Spanish 10: Subtitle (PGS), Portuguese 11: Subtitle (PGS), French 12: Subtitle (PGS), Spanish 13: Subtitle (PGS), English Track 3 is used for destination file "1". Track 3 is used for destination file "track1.ac3" This audio conversion is not supported. W:\STREAM> |

The DTS sample you uploaded is kind of strange. I don't have any problems with the channel order. However, the front left and front right channels seem to be plain broken if I decode the track to 7.1 with ArcSoft. I'm not sure if the track itself is broken or whether this is caused by a bug in ArcSoft. You can use the "-6" parameter to force ArcSoft into decoding the track as 5.1, only. I think this is the best you can do right now. Quote:
Please note that xport fails to demux this sample, just as the old eac3to version does. That's because both xport and eac3to relied on the transport stream to be conformant to specs. TsRemuxer and tsMuxeR both demuxed it fine. It seems that they're using the same demuxing logic which the latest eac3to version now also uses. I guess that it's a bit more error tolerant. Quote:
If there's still a problem then it's not a problem in eac3to, but a problem with Scenarist or with the way you're trying to use eac3to and/or Scenarist. Since I never used Scenarist before, I can't help you with that. If you still need help, please open a new thread, because this thread is not supposed to be a "how to use Scenarist" thread. Quote:

Would you want such a switch to turn of ANY runtime checks? Or do you just want to lower the min runtime a little? I'm asking because there are Blu-Rays with hundreds of playlists! |

eac3to v2.73 released
http://madshi.net/eac3to.zip Code:
* changed TS demuxing logic to make the broken (!) new SkyHD broadcasts work * DTS core and "TrueHD/AC3" AC3 parameters are displayed separately now * when using "-core" option, eac3to now bases its decisions on core parameters * added WAV/W64/RF64 read/write support for 32bit PCM and 32/64 bit float * option "-full" allows WAV/W64/RF64 output to be native (default <= 24bit PCM) * Surcode DTS encoding is now done with up to 32bit float (if available) * Aften AC3 encoding is now done with up to 64bit float (if available) (1) Surcode accepts 16bit PCM, 24bit PCM, 32bit PCM and also 32bit float WAV files. But the DTS Pro encoder only accepts 16bit PCM and 24bit PCM files! (2) The Nero AAC encoder is currently also limited to 24bit PCM input. (3) When using libav decoders and the Aften or Surcode encoder, eac3to has a full floating point chain now from decoder to encoder, including all processing steps in between. Question: Does anybody have any Dolby Digital "EX" samples for me? |

And don't know for what, or if is used in other cicumstances. Thanks for the new relase. Code:
* option "-full" allows WAV/W64/RF64 output to be native (default <= 24bit PCM)

Ouch. Is that the very end of the movie? Please check the file size of "00000.m2ts". Is that near to the reported 32825124864 file position?
Quote:
The "-full" switch tells eac3to that you don't want the bitdepth to be converted when creating WAV/W64/RF64 files. That means if the source is 32bit PCM (and you do no processing on the audio data) the destination WAV/W64/RF64 will be created as 32bit PCM. Or if the source is floating point (or if you did any processing which results in the source being converted to floating point) eac3to will create 64bit floating point WAV/W64/RF64 files. The "-full" switch simply disables the downconvertion to max 24bit PCM. The switch only affects the creation of WAV/W64/RF64 files. |

Could eac3to split audio tracks with chapter info or at specified time point?
I use DGAVCIndex to spilt H264 video at IDR frame and demux audio tracks, it's fine with AC3 and LPCM. But for TrueHD, only the first demuxed one can be recognized by eac3to. |
