Graphs: So, eac3to-nero "looks" like ffmpeg for 5a.ac3, like liba52 for 224.ac3 and like eac3to-libav for 640.ac3. I was surprised even more, when I compared SNR results: Code:
5a-eac3to-libav: 27.194 dB (Gain for File B = 1.0009) 5a-eac3to-nero: 28.607 dB (Gain for File B = 0.99991) 5a-ffmpeg: 29.057 dB (Gain for File B = 0.99994) 5a-nero: 28.625 dB (Gain for File B = 1.5873) 5a-foo-liba52: 28.822 dB (Gain for File B = 0.99985) 224-eac3to-libav: 16.188 dB (Gain for File B = 0.99912) 224-eac3to-nero: 16.18 dB (Gain for File B = 0.99182) 224-ffmpeg: 13.399 dB (Gain for File B = 1.2648) 224-nero: 13.4 dB (Gain for File B = 2.0076) 224-foo-liba52: 16.166 dB (Gain for File B = 0.99174) 640-eac3to-libav: 27.809 dB (Gain for File B = 0.99982) 640-eac3to-nero: 27.813 dB (Gain for File B = 0.99982) 640-ffmpeg: 16.091 dB (Gain for File B = 1.2752) 640-nero: 16.091 dB (Gain for File B = 2.0243) 640-foo-liba52: 27.537 dB (Gain for File B = 0.99971) SNR = 28.844 dB (Gain for File B = 1.5872) As you can see, Cyberlink hasn't that problem with attenuation of high frequencies. Can anyone check these samples with Windows 7 decoder? Or maybe even with reference decoder? Quote:

Edit: Maybe you're confused by dithering? eac3to lets libav decode to floating point. For WAV/WAVs output eac3to dithers the floating decoding data down to integer. Dithering means adding random noise to the data. So it's clear that if you decode the same AC3/DTS track twice with eac3to/libav, the results will be different each time. If you want floating point WAV/WAVs files instead, use the eac3to "-full" switch. Then the files should be identical every time. Yes? Go on, please! Last edited by madshi; 19th May 2010 at 09:16. |

Anyway, have already found a fix for the problem, which will be included in the next build. |

Or could it be a bug in the subtitle track detection ? Code:
F:\Video>"c:\program files\eac3to\eac3to.exe" . 1) L0_mainMovie.EVO+L1_mainMovie.EVO, 1:51:18 "mainMovie" - VC-1, 1080i (16:9) - DTS-HD, English, 2.0, 48khz - DTS-HD, French, 2.0, 48khz 2) trailer.EVO, 0:03:52 "trailerIntro" - VC-1, 1080i (16:9) - DTS-HD, French, 2.0, 48khz 3) specialFeatures.EVO, 0:00:30 "specialFeatures" - VC-1, 1080i (16:9) - LPCM, English, 2.0, 16 bits, 48khz F:\Video>"c:\program files\eac3to\eac3to.exe" . 1) EVO, 1 video track, 2 audio tracks, 1:51:25 1: Joined EVO file 2: Chapters, 12 chapters 3: VC-1, 1080p24 /1.001 (16:9) with pulldown flags 4: DTS Master Audio, English, 2.0 channels, 16 bits, 48khz (core: DTS, 2.0 channels, 16 bits, 768kbps, 48khz) 5: DTS, French, 2.0 channels, 16 bits, 1509kbps, 48khz |

how does the -shutdown command work? I used it with a command line like "eac3to moviefolder 1) 2: movie.mkv 3: audio.flac 3: audio.dtsma 4: subtitles.sup -shutdown"
but my computer didn't shut down afterwards and just idled. |

In the HD-DVD menu, there is only an audio menu (no subtitle choice) and the switch of audio does make appear or disappear the french subtitles. That's a kind of authoring where subtitles are forced when enabling the original english audio track. That's something we have sometimes on DVD. I don't know how it is handled on HD-DVD. |

@madshi
Regarding "shutdown" - You might want to check with "jdobbs" (at his Doom9 sub-forum), the author of BD Rebuilder. Base3d on postings in the BD-Rebuilder thread, he has very recently resolved the identical problem... |

Hi
I have just encoutered a nasty problem using eac3to 3.17. When converting 5.1 48kHz dts files to 5.1 flac, eac3to just stopped without error, leaving an unfinished file and no log. It happen only with one file out of ten. Even worse, rerunning the identical command line once more, the problem does not appear anymore. This has happend twice in the last couple of days. Any ideas? |

Yes, of course I will do that. But since the problem can not be systematically reproduced, it may take a long time for the problem to reappear.
The changelog for 3.18 does not list any bugfixes, so I would expect it to behave the same way in this respect. Meanwhile, I have an idea what could be causing my problem. I remember running two instances of eac3to at the same time. Is this considered a bad idea? Because I have done this quite often without any trouble. I will try to reproduce the problem this way. |

I have only had problem using two instance of eac3to when encoding to DTS using surcode, sometimes (rare cases) it happens that both instance use surcode at the same time and one instance finish before the other. Then it (sometimes) kills both process leaving a unfinished dts file. Maybe its the same that happens for you ?
You could properly check this by making a batch file with the same commandline repeated like 5-10 times and then just make it run over and over again to see if it fails at any point. If this work, then try to make 2 batch and run it at the same time. Dont use the same destination folder in both batch job, it will sure fuck it up. Last edited by GZZ; 24th May 2010 at 10:05. |

I'm interested in slowing down some 24.000fps Blu-rays to 23.976fps, since it's the preferred standard for my 60hz sets. Most of them are originally 16-bit though, and since slowing them down with eac3to increases their bitdepth to 24-bit, that takes some of them over the 25GB limit for SL disc burning (after converted back to DTS-MA with the DTS encoder). I'm not gonna waste a BD50 to fit on an extra 800MB or so. I know I can reduce them back down to 16-bit with the -down16 option but I'm worried about the effect all the conversions would have on quality. 16->64->24->16 is a lot of steps. Should I just live with 24fps or will there not be any noticeable sound quality difference after all the conversions?
