I did a very similiar process with Nemo, but am wondering about the resulting file sizes.
Original THD, w/core : 5.1 gb Extracted thd (no core) : 4.6 gb ffmpeg THD to flac (w/expected 4 errors) : 2.2 gb eac3to flac to 8 wavs : 851 mb each DTS-HD MA suite to DTSenc.dtshd (w/core) 7.1 : 2.6 gb I have done many THD to DTS-HD conversions in the past and have never seen this big a descrepancy in file sizes. The DTS result syncs up with the movie just fine, however there is a difference in the bitrates to the original THD track. I imagine it's still lossless, but who knows?

No, not yet.
Here's my errors: Code:

I beleive those 4 errors screwed the pooch on this track.

Lossless check failed - expected 00, calculated f4.s/s Lossless check failed - expected 00, calculated 65.s/s and that is indeed a big difference in BR. for me it's ok since I just needed DTS |

But this isn't the case, the wav's files have the correct size for a mono, 48 Khz, 24 bit, 1h 43m Here the strange size is the 4.6 GB for the TrueHD file. I always see a size for thd between flac and dtshd sizes. The size and the errors let me suspect for a incorrect extraction. And, maybe, the wav's have garbage at end because the length of the movie is only 1:40:54, but in sync with the video. The size of monowav's for 1:40:54 must be 831 MB instead 851.

ffmpeg output
Hello,
I am curious about something... I decoded an ac3-file to pcm wav with eac3to which used the libav/ffmpeg decoder. Then i did the same thing in Linux, but there I did it straight with ffmpeg (version 0.10.3). I compared the outputs in a wave editor and discovered that eac3to produces files with 'larger / louder' waves than ffmpeg. How can this be while eac3to is also using the ffmpeg decoding system? Thanks in advance for your insights. EDIT: this is not due to the removal of dialog normalisation; I already ruled that out. |

I fixed it; I had put the option in the wrong order in the command line.
Using this: ffmpeg -drc_scale 0.000000 -i sound.ac3 -f wav sound.wav gave me the exact same wav-file as was produced by eac3to. Thank you for getting me in the right direction. |

Using myprocess.start to run eac3to PROBLEMS
I have been trying for days to make the code below work.
If I set createnowindow=true and disable standard output eac3to runs fine in the command box but just locks up when run with the command box hidden. This same routine works for mkvmerge tsmuxer and eac3to to read the mpls files.\ I have tried read, readline and readtoend all without success. Any thoughts thanks Public Function StartFile(ByVal MyApp As String, ByVal MyTail As String) As Integer Dim myProcess As New Process() 'Dim test As String = Chr(8) myProcess.StartInfo.WorkingDirectory = Application.StartupPath myProcess.StartInfo.FileName = MyApp myProcess.StartInfo.Arguments = MyTail myProcess.StartInfo.UseShellExecute = False 'myProcess.StartInfo.CreateNoWindow = false myProcess.StartInfo.CreateNoWindow = True myProcess.StartInfo.RedirectStandardOutput = True 'myProcess.StartInfo.RedirectStandardError = True Try myProcess.Start() myProcess.PriorityClass = ProcessPriorityClass.Idle While (myProcess.HasExited = False) Application.DoEvents() Dim sLine As String = myProcess.StandardOutput.ReadToEnd If (Not String.IsNullOrEmpty(sLine)) Then TextBox14.Text = sLine End If If UserCancel Then myProcess.Kill() ProcEC = 9 Return ProcEC End If End While ProcEC = myProcess.ExitCode Catch ex As Exception MsgBox(" Error(s) with startfile " & MyApp & " " & ex.Message) ProcEC = 99 End Try myProcess.Close() Return ProcEC End Function |

Hi there. I'm a bit confused about something, here it is...
Code:
1: Chapters, 9 chapters 2: h264/AVC, 1080p24 /1.001 (16:9) 3: RAW/PCM, Japanese, 2.0 channels, 24 bits, 48kHz 4: DTS Master Audio, Japanese, 5.1 channels, 24 bits, 48kHz (core: DTS, 5.1 channels, 24 bits, 1509kbps, 48kHz) 5: TrueHD/AC3, Japanese, 5.1 channels, 48kHz (embedded: AC3, 5.1 channels, 448kbps, 48kHz) 6: AC3, Japanese, 2.0 channels, 384kbps, 48kHz 7: Subtitle (PGS), Japanese a04 Extracting audio track number 4... a04 Decoding with ArcSoft DTS Decoder... a04 Encoding FLAC with libFlac... a04 Creating file "C:\Users\ST\Desktop\1_4_audio.flac"... a04 The original audio track has a constant bit depth of 16 bits. a04 Superfluous zero bytes detected, will be stripped in 2nd pass. a04 Starting 2nd pass... a04 Decoding FLAC... a04 Reducing depth from 24 to 16 bits... a04 Encoding FLAC with libFlac... a04 Creating file "C:\Users\ST\Desktop\1_4_audio.flac"... a04 The processed audio track has a constant bit depth of 16 bits. Video track 2 contains 133434 frames. eac3to processing took 10 minutes, 12 seconds. Done. |

At first glance, far too many Japanese audio/sub tracks.
Seriously though, completely normal when there is padding present. Happens all the time. By eac3to removing it doesn't change the quality at all. Still lossless. BTW, no one can accuse you of being a post whore, 1 post in 4 years!!

Hey all,
I tried about five times now to encode the DTS-MA audio from 'Fellowship of the Ring' using Arcsoft, eac3to, and Nero. Every single time, instead of a 1h:45min multichannel file, I get a 2:00:48 file that's all distorted and useless. I have no idea why this is happening. It's a 6.1 DTS, which there was some info about earlier in the thread about remappings and such from about a year ago. The information does not seem applicable though, since it's about a year old, and since I don't receive any error messages about channel mappings (eac3to automatically detects that it's a 6.1 file and doubles the back channel in order to facilitate compatibility with NeroAacEnc). In any case, I tried what was suggested - manual channel mapping plus the '-double7' switch - and it changed nothing. I also tried to encode just the DTS-ES core - that didn't help at all. Thanks to the Arcsoft filters, the DTS file does play in MPCHC, but a) with terrible seeking b) a reported running time of 05:24:44. I am using Arcsoft 1.1.0.8, eac3to 3.24, and Nero 1.5.4.0. Anybody know how to encode this thing? -e Last edited by bilditup1; 18th December 2012 at 02:15. Reason: more info |
