Tried to extraxt PCM 24bit with TsMuxer, The result what 2 files ???
Using eac3to = 1 file, with this messages... [a03] Extracting audio track number 3... [a03] Reading RAW/PCM... [a03] Swapping endian... [a03] Remapping channels... [a03] Writing WAV... [a03] Creating file "g:\bill2.wav"... [a03] This audio track has a constant bit depth of 24 bits. [a03] Caution: The WAV file is bigger than 4GB. [a03] Some WAV readers might not be able to handle this file correctly. Video track 2 contains 197030 frames. eac3to processing took 48 minutes, 54 seconds. This files was OK when adding to a MKV ( no error messages with mkvmerge :-) ) I'm trying now to use command -down16 and add that also to the MKV Tomorrow I going to try this MKV:s at my TviX :-) |

There's a problem with AGM files.
DTS Pro Encoder will accept all AGM files made from DTS-HD Master Audio tracks, but will reject every single AGM file made from TrueHD tracks (haven't tried with LPCM as source). The encoder pops up am message saying that this isn't a valid source file. This happens all the time regardless the source track is 16bit or 24 bit. In addition, mono wavs created from TrueHD tracks work fine with the AGM packer of the encoder and the actual encoder afterwards. Last edited by nautilus7; 29th September 2008 at 23:47. |

if the decoded TrueHD track is less than 4GB the problem is not there.
@madshi just to save you time in investigating the problem: at least when eac3to decodes TrueHD track to AGM and the decoded file is over 4GB, eac3to writes wrong value for SAMP chunk in the header. example: the created AGM file size: 4877833220 bytes SAMP chunk value: 4877833220 - 260 = 0x122BDD300 eac3to writes for SAMP value: 00D3 BD22 0000 0000 instead the correct value of: 00D3 BD22 0100 0000 Last edited by xkodi; 30th September 2008 at 03:58. |

Stupid question , if I demux m2ts with eac3to which has audio delay of -9 ms, do I then need to add -9 delay in TSMuxer when I mux it back to m2ts? Or does eac3to somehow fix that delay when it demuxes it.

Hi, I've lurked here for a long time and finally registered recently. I do have a question, and I realize this might have been answered somewhere along the way, but I'm new to this and honestly all of this information can get very confusing and frustrating to a newbie. So please accept my apologies if a question like this is annoying.
I've recently learned how to back my Blu-Ray's to a .mkv container on my PC using MeGUI and a plethora of other programs. I just bought a new Blu-Ray and when I open it using tsMuxer I only see one English audio track which is in TrueHD. When I demux it, it comes out as a AC3 file, but after reading this thread I'm thinking that's not how I should extract the stream. My question is how do I remove the TrueHD stream from the .m2ts file and then how do I convert that to AC3? I've read quite a bit of this thread, I saw at one point someone said something in regards to there being an AC3 stream that's coupled with the TrueHD stream. If that's true, I would just need to extract the AC3 stream, correct? I'm just unclear on how to do that. I was able to figure out by myself how to backup a blu-ray, which took awhile, but for some reason I'm really lost as to how I can get this to work. I searched for guides on how to do this and didn't really come up with anything, or at least anything that I really understood. I hate asking something when I'm sure 95% of everyone here will roll their eyes, but this is a last ditch effort. If anyone could help it would be appreciated. Thanks. |

DTS-HD bit-depth is known from the beginning and thus the correct size, i suspect that with TrueHD size is calculated at the end after the check if the last byte is zero or not and probably the calculation at the end is broken and assumes that the maximum possible size is 4GB (32bit) like in the WAV file, but AGM supports 64bit size.

You just need to modify the command in the last step to correspond to the TrueHD/AC3 combo track (change the extension of the output file to .ac3). This will give the AC3 track that already exists into the Blu-ray. If you also need the TrueHD, change extension to .thd. Last edited by nautilus7; 30th September 2008 at 11:49. |

Can you add MKV to "Supported source formats" ? PLEASE !
P.S. I know there are other "tools" for demux all video and audio tracks of an mkv but I'd like (as many others) to keep things simple (and not having a lot of programs installed)

So sad TviX can't handle PCM/WAV sound inside MKV files :-( But no problem to add this PCM/WAV to a MKV :-) |

Did anybody ever experience the following error and has found a workaround?
Code:
[a05] Removing TrueHD dialog normalization... [a05] Decoding with libav/ffmpeg... [libav] Substream 0 checksum failed [libav] No restart header present in substream 1. [a05] The libav decoder reported an error while decoding. Aborted at file position 81920. Last edited by zyrill; 30th September 2008 at 20:48. |

Code:
eac3to Shoot.'Em.Up.2007.Blu-ray.flac" shoot.em.up.aac FLAC, 7.1 channels, 1:26:32, 24 bits, 5095kbps, 48khz NeroAacEnc only supports 6 channels. Will mix the surround channels. Decoding FLAC... Mixing surround channels... Loading white noise (needed for dithering)... Encoding AAC <0.50> with NeroAacEnc... This audio track has a constant bit depth of 24 bits. eac3to processing took 12 minutes, 35 seconds. |

madshi, it would be nice if eac3to displays the profile of the AAC file (LC, HE, HEv2), runtime and the bitrate even in vbr tracks, like it's done in flac.
