Just joking, of course. When compiling ffmpeg with the default options, you won't get 24bit TrueHD tracks decoded properly. Instead you'll get them only as 16bit. Because of that I've compiled ffmpeg with special config flags. Basically after ./configure you have to edit config.h and add the following two switches: #define USE_HIGHPRECISION 1 #define CONFIG_AUDIO_NONSHORT 1 Afterwards you can use "make" as usual. This config change makes sure that the MLP/TrueHD decoder outputs the data as 32bit instead of as 16bit. This is necessary to get full 24bit from 24bit TrueHD tracks. BTW, if you do recompile ffmpeg once in a while with always the latest MLP/E-AC3 decoder patches, I'd be thankful if you could send me the dlls, so that I can update them in my eac3to distribution. I hate recompiling C++ projects, so I'll only do it rarely. |

E-AC3, 5.1 channels, 2:23:27, 1536kbit/s, 48khz, dialnorm: -27dB Removing dialog normalization... Decoding with DirectShow (Nero Audio Decoder 2)... Disabling DRC for Nero (E-)AC3 decoding... C:\HDTV-Tools\eac3to> I did not buy the plug-in. I thought it only needed the nero audio decoder 2, to go from a demuxed file to ac3. Maybe this is the problem? |

Yes, that's most probably the problem. You do need to buy the plugin and register it properly. |

I can't reproduce the problem with a sample. Only the original (uncut) thd gives differences in the beginning of each wav channel. There are 4 different bytes at the first 48 bytes of each channel.
Ah, it just came to me! It has to do with other problem (at the end of the file), i think. I believe these different bytes in the beginning have to do with the track runtime, which is different when i decode the original (uncut) .thd (by 1 ms) and exactly the same when i decode the sample. So, nothing to worry for now, at least. If it's not fixed when you fix the "end" problem, then i 'll bring it back. |

2 hints
1. Feature request: I would like you to add an option to choose which channels to decode, when the output format is .wavs. 2. Shouldn't that be the opposite order (the bold letters), like with nero decoding? Code:
C:\Tools>eac3to input.thd output.wavs -libav TrueHD, 5.1 channels, 48khz, dialnorm: -27dB Writing WAVs... Removing dialog normalization... ... C:\Tools>eac3to input.thd output.wavs TrueHD, 5.1 channels, 48khz, dialnorm: -27dB Removing dialog normalization... Decoding with DirectShow (Nero Audio Decoder 2)... DirectShow reports 5.1 channels, 24 bits, 48khz Writing WAVs... ... |

Quick question...
Finally got everything working for EAC3 decoding, however all my HD DVD EAC3 tracks that I'm using are recognised as 24bit, is this normal? Or is possibly Nero HD DVD plugin doing something to them that it shouldn't? Thanks... |

Is there a proper way to make a 7.1 -> 6.1 downmix (for DTS-ES 6.1 Discrete encoding)?
(got the encoder, so that's not the problem) If nobody 'complains' I'm gonna make the Cs [Center Sorround] channel by mixing BL & BR channel. /edit 6.1 PCM: BL = BR = CS Last edited by hristoff2; 26th November 2007 at 20:41. |
