Thank you nautilus7, always here to help me
I don't need to use xport anymore to demux audio part, eac3to will do that ? EDIT: I did this : eac3to.exe emily.m2ts 3: fr.ac3 And I get an error : This TS/M2TS file seems to be damaged (discontinuity). Last edited by Kal; 25th March 2008 at 15:30. |

This is the result of joining the multiple .m2ts files. Xport usually reports a lot discontinuities which don't cause any problems. The same should apply here. Try xport also to be sure, but i don't think it will make any difference.
There isn't any program that can join .m2ts files and take care of audio/video overlaps/gaps. This means it's possible a lot of blu-ray discs with seamless branching to show audio/video desync (caused by discontinuity errors). (Madshi could explain this better) Proper .m2ts joining will done by eac3to in the future. Last edited by nautilus7; 25th March 2008 at 16:02. |

noticed that the demuxed truehd track from the fifth element blu-ray (remastered) by eac3to is ~500mb shorter than the one I demuxed with xport. (2,80 vs. 3,36 GB). is this supposed to be normal?
the track is said to have 20 or 24bit (24 bit reported by madflac, 20 bit said by highdefdigest.com). the flac filesize is 2,54 GB Last edited by Thunderbolt8; 25th March 2008 at 16:09. |

yes, should be. hm I also remember having see that the flac track from the LPCM track is only ~1.5gb, since the LPCM track is only 16 bit (size: 4,05 GB). is the ending .pcm the right one btw. for demuxing that track? because eac3to is swapping endians and remapping channels 2 times then and the -demux switch doesnt seem to work for .m2ts files

The "-demux" switch currently works just fine - but only for movies where there's no combined TrueHD/AC3 track. The "-demux" option has a bug which stumbles over such combined tracks. That will be fixed in the next build. The next build will then demux both the TrueHD and the AC3 parts of such combined tracks into separate files, if you use the "-demux" option. |

With HDMI bitstream support coming (Intel G45 & Asus HDMI soundcard), and assuming there will be .mkv player support for same, will an option to preserve the original DD+, TrueHD and/or DTS-HD MA tracks be fourthcomming?

However, I'm quite sure that Intel G45 and the Asus HDMI soundcard will also allow multichannel PCM output. Which means that FLAC is just as good as DD+/TrueHD/DTS-HD MA bitstream. So I will continue to use and recommend FLAC. |

I loaded in a DTheater capture just for fun, tried to demux, and I got this message:
TS, 1 video track, 2 audio tracks 1: MPEG2, 1080i60 /1.001 (16:9) 2: AC3, 5.1 channels, 576kbit/s, 48khz, dialnorm: -27dB 3: DTS, 5.1 channels, 20 bits, 1536kbit/s, 48khz Extracting primary video track... Extracting audio track number 2... Extracting audio track number 3... Patching bitdepth to 24 bits... Removing dialog normalization... Creating file "dtheater.m2v"... There's a change from interlaced to progressive in the middle of stream. |

Hi Madshi,
I know i've asked this before, and i know i havent followed this thread as well as i did; But have you made it possible to de/transcode (regular) AC3 with libav at this time ? As i said earlier; I dont have Nero installed, and i try to use as much Open Source software as possible; So i am really interested in a feature like this. And i ask this again because somewhere earlier in this thread it was mentioned that libav's decoding had been improved (afaik). |

I converted an ac3 file to a lower bitrate ac3 file with this command line on a pc without nero or sonic decoders. Code:
eac3to.exe 384kbps.ac3 192kbps.ac3 -192 -libav |

Yes. eac3to can decode E-AC3, AC3, DTS and TrueHD/MLP with libav. |
