-phaseshift is not recommended if source is ac3 because the surround channels are already phaseshifted, if you do other phaseshift the result was wrong. -normalize is the parameter recommended after a downmix to obtain the max volume, instead the arbitrary +6dB Quote:
Now eac3to don't decode with DRC activated and Aften can't do correct DRC management.

Subtitles still not showing on some Blurays.
I think there is a small bug in EAC3to way of parsing the mpls files and the m2ts files.
I did a test on Der Untergang (Nordic version) Quote:
There is also a problem with extracting video and audio from this using the mpls file. Because the audio goes out of sync because of the small 00010.m2ts black screen file. Giving you this when extracting: Quote:
Last a small request if possible. If you want to extract the chapters, is it then possible to do this without having eac3to to scan the video stream. As the chapters are located in the mpls file ? |

@Madshi...
is this a bug ? Processing a HD-DVD, giving an explicit name eac3to accepts it, writes it in the log: Code:
command line: "C:\Program Files\eac3to\eac3to.exe" "E:\" 1) 2: "C:\Temp\Batman Begins\Chapters_2.txt" 3: "C:\Temp\Batman Begins\Video_3.*" 6: "C:\Temp\Batman Begins\Audio_6_Undetermined.THD+AC3" -LOG="C:\Temp\Batman Begins\eac3to_PASS3_LOG.LOG" ... [a06] Creating file "C:\Temp\Batman Begins\Audio_6_Undetermined.THD+AC3" Code:
Audio_6_Undetermined DELAY 200ms.THD+AC3 |

madshi,
can you compare these flac files created by eac3to? http://www.sendspace.com/file/scv0kk The method: Extract mlp+decode to wav with DVD-Audio Explorer 2008.07.21 (Beta3) by MaximA and retransmit to flac via eac3to. Code:
eac3to\eac3to C:\users\rica\desktop\tracs\E.wav C:\E\E_01.flac ------------------------------------------------------------------------------ WAV, 5.1 channels, 0:06:32, 24 bits, 13824kbps, 96khz Reading WAV... Encoding FLAC with libFlac... Creating file "C:\E\E_01.flac"... The original audio track has a constant bit depth of 24 bits. eac3to processing took 1 minute, 30 seconds. Done. _ _ _ _ _ _ _ http://www.sendspace.com/file/8snz93 The method: Extract mlp directly with DVD_Audio Explorer and transmit to flac with eac3to. Code:
eac3to\eac3to C:\users\rica\desktop\tracs\E_new.mlp C:\E\E_new.flac ------------------------------------------------------------------------------ MLP, 5.1 channels, 24 bits, 96khz Decoding with libav/ffmpeg... Encoding FLAC with libFlac... Creating file "C:\E\E_new.flac"... The original audio track has a constant bit depth of 24 bits. eac3to processing took 2 minutes, 12 seconds. Done. _ _ _ _ _ EDIT: Here is the extracted original mlp (by method2): http://www.sendspace.com/file/xj5698 _ _ _ _ _ Last edited by rica; 22nd February 2009 at 21:51. |

It's not a bug, it's a feature! It's telling you, in a way that makes sure you don't forget it, that you need to delay that audio track 200ms when you are muxing it (eg using tsMuxeR). eac3to can't apply TrueHD delay itself so you have to delay the whole track when muxing, or it will be out of sync.

Your best bet would be to convert the TrueHD losslessly to an LPCM stream using eac3to (or one of the tools that use it, maybe the above, maybe ToNMT?). The WDTV should be able to support multichannel LPCM over HDMI. You say you've tried that but you don't say what exactly you've tried and what exactly's happening. Of course, if you're not using eac3to, there are other places that should be able to help you better. |

Yep, seems the remap needed is missing (or now libav is correct and don't need remap).
We have problems with 18,19 and 20 modes Code:
# MLP Channel Assignments MS channels order libav remap -- ------------------------ ------------------ ----------- 18 Lf Rf Ls Rs (LFE) FL FR LF BL BR -0,1,4,2,3,5 19 Lf Rf Ls Rs (C) FL FR FC BL BR -0,1,4,2,3,5 20 Lf Rf Ls Rs (C LFE) FL FR FC LF BL BR -0,1,4,5,2,3

FLAC is indeed a better (more efficient) choice IF you have a device that will play it back, such as a PC. The OP wanted to hear lossless audio on his WD TV and there's no way that's playing back multi-channel FLAC. However, it should play LPCM as there's no decoding involved. The recommendation was just for those circumstances.

A delay specified in the filename like that, or just a delay reported when eac3to is running? eac3to fixes the latter delays, doesn't fix the former. And I guess sometimes it might put a delay in a filename when it doesn't need to, I'll let madshi speak to that, but believe me it's there for a reason.
