What is the video frame duration @23.976 fps? Next question. I extracted a Dolby THD track to wavs, where the track has a video delay of -32ms. The log shows (note lines 2 and 7): Code:
[a03] Extracting audio track number 3... [a03] This track begins with a non-major frame. <WARNING> [a03] Extracting TrueHD stream... [a03] Removing TrueHD dialog normalization... [a03] Decoding with DirectShow (Nero Audio Decoder 2)... [a03] DirectShow reports 5.1 channels, 24 bits, 48kHz [a03] Applying RAW/PCM delay... [a03] Writing WAVs... So, does the "applying RAW/PCM delay..." mean that I don't have to apply any delay when muxing the DTS track back with the video?

1000 ms / 23.976 = 41.7 ms

@tebasuna51
As always, thank you for the quick and knowledgeable response. I'm always a bit confused by audio/video delays. Also, this is the first time I've seen "This track begins with a non-major frame. <WARNING>"

A TrueHD stream is composed of Major sync frames and non-major frames. Apparently tracks are supposed to start with a major frame.
This may have accounted for the -32ms delay and the warning.

Love how useful this tool is. I have 2 feature requests:
1) A SoundTouch type Tempo adjustment. The ability to speed up and a slow down a track without any change to the pitch is sometimes preferable. 2) Dolby Pro Logic II/IIx/IIz Upmix. I often want to expand the number of tracks on a stereo source to 5.1 or 6.1. Manually doing this is labor intensive and requires multiple programs and in between conversions. Be nice to just: Eac3to StereoTrack.wav SurroundTrack.ac3 -upDpl6 |

EDIT - Careful searching found that for any 6.1 format the remap must be done to accomplish -double7 processing correctly.
Hey everyone, I have a 6.1 channel .w64 file with L C R LFE BC SL SR channel mapping, and I need to upmix to a 7.1 .w64 file for proper muxing with TSMuxer (TSM does not like 6.1, and converts it to 7.0, putting my LFE channel in one of my rear surrounds). Can I simply use the -double7 feature, or do I need to remap channels as I have found when searching for how to use the '-double7' feature? I was wanting to just use: eac3to input.w64 output.w64 -double7 Will this work? Thanks in advance, JSS Last edited by maxmercy; 10th July 2013 at 21:47. |

Could we please get a replacement of the FLAC encoder with the one in ffmpeg 2.0 with "-compression_level 12" ?
It now properly supports 24bit. I have tested up to 24bit 7.1 channel FLAC and it plays fine on all the players I have tried (XBMC, MPC-HC, etc...). "-compression_level 12" allows to shave off another 100 to 200Mb on my MKV backups. It's a little cumbersome to compress to FLAC with eac3to and then to recompress it again to FLAC with compression level 12 with ffmpeg. It would be nice if we could do it in one go. Thanks. |

I am using the HD-DVD/Blu-Ray Stream Extractor (the MeGUI version as it allows to queue tasks - this way I can set up 20 or more MKV to FLAC taks in the queue and have it run in one go), so I don't think it's possible to setup piping with the gui.
Thanks for the feedback. |

I tested simple piping to ffmpeg and it doesn't seem to work properly :/ The resulting file is only a part of the source, maybe it's due to some filesize restrictions. I couldn't find a way to force ffmpeg to ignore any audio length. The documentation of that application is just not very clear (I've ran into that many times in the past), but some googling told me that ffmpeg should support large files without a problem. There is something funny there anyway, I also tried decoding to wav and then using ffmpeg on the result but it didn't help either.
