eac3to v2.74 released
http://madshi.net/eac3to.zip Code:
* "-demux" failed to work for DTS-HD and "TrueHD/AC3" tracks in v2.73 * fixed: DTS-HD tracks could make processing abort at the very end of the movie |

Conversion concern/question
Would converting a TrueHD (48/16) track from an HDDVD to PCM (for BD playback) sound the same as the same movie on Blu-ray with with the audio already as PCM (48/16)?
All of this done with eac3to of course. |

Just to be sure that's the expected behavior (last DTS frame incomplete) ? Code:
[a07] Remapping channels... [a07] Encoding AC3 <640kbps> with libAften... [a07] Creating file "Total.Recall.Blu-Ray.23.976fps.DTS.FRENCH_2.dts"... [a07] Creating file "Total_Recall.DD5.1.French_2.ac3"... [s13] Creating file "French_2.sup"... [a07] The last DTS frame is incomplete and thus gets skipped. [a07] The last DTS frame is incomplete and thus gets skipped. Video track 2 contains 163366 frames. eac3to processing took 26 minutes, 37 seconds. |

another thing, this is old already, but after not thinking about it for some time I got confused again -.- when having a movie of which eac3to reports +57ms delay for the AC3 track, what eac3to then does is adding 2x -32ms = -64ms delay to it, so that the least possible delay remaining is then -7ms, right? so in case I want to have it perfectly I'd have to add +7ms at playback then in mpc (I know this is imperceptible, but just for perferction)?

Bsid = 6 (Alternate syntax) Xbsi2e = 1 (Exist Extra BSI #2) Dsurexmod = 2 (Dolby Surround EX encoded) Remember the Table D2.1 (pg. 132) from a52b pdf to locate the fields in header, or see this seudo-code.

Does this logic apply also to say 5.1 DTS-HD/TrueHD > 5.1 DTS 1536 or 5.1 AC3 640? i.e. instead of using the available 5.1 DTS 1536 or 5.1 AC3 640 track, to transcode a new track from the DTS-HD or TrueHD tracks? Or is that only relevant when talking about a core+data situation instead if there was separate tracks available i.e. DTS-HD (core+data) and a separate DTS 1536 track or TrueHD (core+data) and a separate AC3 640 track. Keep up the amazing work! |

Not for me. If you can't seem to be able to get v2.74, please try emptying your browser cache. Quote:

The situation is different, if there already exists a core in the very format and bitdepth you're looking for. In that case transcoding is not necessary at all, but you can simply extract and use the existing core. But as soon as you need/want to transcode (which means: full decoding + reencoding) you should always choose the source with the highest possible audio quality. |

It just seemed kind of strange that watching the bitrate (HDDVD THD remuxed to BD --> on the PS3) that it only peaked at around 1.7mb/s, even during high action scenes. Where on most BDs with THD they peak around 4.5mb/s. I know it's like "comparing apples to oranges", but it's not even close. |

madshi, I have a problem with slowing down that skyHD movie I sent you the 10mb sample to fix the skyHD ac3 tracks. its 50i and when I use -slowdown then the video turns out to be about 2-3 mins longer than it should be (audio seems to be fine though). It has video gaps, but the problem stays the same after redoing the same command line. 50 mb sample:

Well, if you absolutely must have all 8 channels then you can do "eac3to source.dts 6.wavs -6" and also "eac3to source.dts 8.wavs". That way you will get 6 WAV files for the 6 channel decoding and 8 WAV files for the 8 channel decoding. You can then use the 8 WAV files - but replace the front left and front right channels with those of the 6 channel decode. The only problem then is to convert the 8 channels back into one WAV file. eac3to cannot do that currently. But I think wavewizard can. |

TSmuxer destroys some informations while joining and remuxing. I Want to play it in a PCH B-110. When I remux it with TXRemux again it is okay but buggy. The problem is the joing of the Playlistfiles. 1:1 copied full Mainmovie m2ts work fine after remuxing with TSRemux, so the joining and TSmuxer is the problem. Can eac3to do that?! Joining multiple m2ts files (like it does with evos)? Thanks, greetings Michael
