eac3to v2.48 released
http://madshi.net/eac3to.zip Code:
v2.48 * 96kHz LPCM tracks in (M2)TS and EVO/VOB containers didn't work correctly * "Applying (E-)AC3 delay" now only shows if the bitstream is actually modified * fixed crash in MP2 reader when checking some PCM tracks * added support for MLP formats 13 - 16 * improved/corrected MLP channel descriptions * MLP parser sets correct channel mask * added proper channel remaps for libav MLP decoding of "funny" channel formats * added proper channel remaps for Nero MLP decoding of "funny" channel formats * added proper channel remaps for Nero AC3 decoding of "funny" channel formats * when doubling 7th channel the channel mask is set correctly now * channel mask is corrected if a decoder doesn't output all channels * channel mask is corrected if a channel downmixing is performed |

when rename w64 file 2 pcm file -> eac3to detecting file fine, but the channel masking is't right original -> produced by eac3to L -> SL R -> SR C -> L LFE -> R SL -> C SR -> LFE maybe U can look at this simple need channel remaping -4,5,0,1,2,3 Last edited by menlvd; 22nd June 2008 at 15:38. |

thanks!
regarding all those mlp changes/fixes, does that mean that some former converted flac tracks could possible be 'wrong' or not working correctly? and regarding the problematic mpeg2 .ts files, is this already adressed here as well and I can try it again with 2.48? |

madshi recommended h264info, and he would be a much better source than I ever hope to be on the subject. If you plan on re-encoding the h264, then DGAVCDec will recognize the pulldowns and frame serve them minus the pulldowns.
I've used tsmuxer in the past, but found that eac3to seems to always keep audio and video in sync and I never have any problems dealing with anything it ouputs. I'm probably not the normal eac3to user, I normally just extract the video track and convert one of the English audio tracks to a lower bitrate ac3 stream. |

Does it report 29.97 after you let it(DGAVCIndex) finish? It will report 29.97, but when it finishes it will say that it has pulldowns and would you like to remove them(or something similar to that), click yes and it will then serve them without the pulldowns, at least that was my experience, I think it was with Beowulf that I used it for.

EDIT1: I just re-ran DGAVCDec and it never asked to remove the pulldowns. EDIT2: Change the setting to FORCE FILM and it appears to have worked. Thanks. Last edited by rack04; 22nd June 2008 at 18:03. |

Great to know that this is not the case with eac3to. Because then you can have your receiver or software like ffshow do the lfe +10dB boost on all remuxes created with eac3to. This might be ot, but how do I use Graph Edit to decode my 7.1 DTS-HD MA tracks with Arcsoft TMT audio decoder? I extracted the audio tracks long ago to .dts files. I can't connect the output pin from Sonic HD Demuxer to Arcsoft HD Audio decoder without having Sonic Cinemaster Audio decoder or ffdshow conncted in between. |

In the meanwhile I've found a way to make the ArcSoft DTS Decoder work inside of eac3to. However, I have to tell the decoder how many channels I want to have decoded. That's problematic because my DTS-HD channel detection isn't really reliable... Last edited by madshi; 22nd June 2008 at 19:06. |

madshi,
My PC has 2 disks, and I usually work with eac3to from one disk to the other and vice-versa until all the processing needed is terminated. From my experience with eac3to it appears that some of the tasks use temp files. I believe this should be a very simple thing to change, so is it possible for you to create some kind of setting to be used by people like me who uses two disks? It would be great for processing speed and also for disk protection. For example: Demuxing 1 video and 2 tracks for the raw streams took 9m16s. Demuxing 1 video track to mkv and 2 audio tracks for raw streams took 11m18s. It appears the video to mkv has some kind of temp file, I only don't know if it's located in the source disk or the target disk. Thanks for your great work! |

I am quite sure I have dts-ma 4ch track (don't know if it's 4.0 or 3.1) but I can't find it right now. I guess that counts as "funny" format. See 4-5 pages back, where xkodi posts his findings + graph. Last edited by nautilus7; 22nd June 2008 at 23:55. |

Yes, it does. If you find, can you please upload a small sample (5MB is enough)? Thanks... |

just a quick question guys.. not sure if it has been asked - i've skimmed through quite a few pages of this thread already.
when converting tracks to DTS - is the general consensus that: TrueHD to DTS > E-AC3 to DTS? or TrueHD to AC3 > E-AC3 to AC3? TrueHD is decoded using ffmpeg, eac3 decoded by nero. Are nero's eac3 decoders better quality? Which mode retains the most information? Last edited by ideas_man69; 23rd June 2008 at 07:57. |

1. TrueHD -> PCM 2. TrueHD -> DTS 3. 640K/> EAC3 -> AC3 (core for BluRay) 4. 768k/< EAC3 -> DTS BluRay: 1. TrueHD -> PCM 2. TrueHD -> DTS 3. TrueHD -> AC3 (core) 4. EAC3 (see HD-DVD) IMHO, best quality is these orders. Depends on your hardware. Last edited by EPiPH0NE; 23rd June 2008 at 20:28. |

I see that you havent made a reply to my post. Do you haveyou plans/time/possibillties to fullfill my request (converting to 24fps), or shall i simply keep using AviSynth + SoundOut () ? |

Oops, sorry i overlooked that. My bad ... Regarding the 24 fps though; More and more displays are beinig "optimized" for 24 fps. Many newer display-manuafacturers even market those functions ("Real cinema 24fps" kind of features). My Panasonic 42pz85 is made for/accepts 1080p24 (and other 24 fps), and so are all displays from this years (2008) generation. And not only displays are made to work on 24 fps, so are the (newer) players. My dpm dp30 has a specific setting to let it output at 24 fps; But also the PS3 has had an update to output @ 24 fps, and many other players recently been made fit to work on 24fps. I do not know on what fps movies are encoded and/or stored on the physical disk, if it is 23,976 or not; But even PC-apps & rippers prodce 24 fps these days (and even the "less legal" full BD-rips / torrents often seem to be 24 fps). But now i'm rambling on ... but i think 24 fps will be seen more often in the future. Last edited by G_M_C; 23rd June 2008 at 09:58. |

With less channels Surcode put empty channels. For instance: Code:
eac3to v2.48 command line: "D:\Test\AudioN\eac3to\eac3to.exe" "E:\Test\wavs\2w200.wav" "E:\Test\wavs\2w200.dts" ------------------------------------------------------------------------------ WAV, 2.0 channels, 0:00:20, 16 bits, 48khz Reading WAV... Writing WAVs... Creating file "E:\Test\wavs\2w200.L.wav"... Creating file "E:\Test\wavs\2w200.R.wav"... Found Surcode DTS Encoder version 1.0.23.0. Surcode encoding successfully started. Please wait... Closing Surcode... eac3to processing took 1 second. Surcode encoding took 6 seconds. Done. eac3to v2.48 command line: "D:\Test\AudioN\eac3to\eac3to.exe" "E:\Test\wavs\2w200.dts" ------------------------------------------------------------------------------ DTS, 5.0 channels, 0:00:20, 24 bits, 1536kbit/s, 48khz Quote:
AFAIK, the encoders can use only (forced or optional) a lowpass filter for LFE channel. Other question is the recommended relative volume level between channels, but is a free choice for the soundtrack author. |
