@Madshi
I've discovered (well, I've been told about, technically) an issue with eac3to recognizing original, unused DTS-HD files. By unused, I mean the files created by the DTS-HD Master Audio Suite (the software that the studios use to actually create the DTS-HD MA audio). The DTS software creates files with an extra 140 bytes of header information at the beginning of the files. This information is stripped off when the DTS is used on a final disc, so if you rip DTS off a Blu-Ray disc, this data is not there. Thus, eac3to doesn't recognize a DTS file with this information... The header isn't vague, the first 8 characters are DTSHDHDR. It would be great if the software could be updated to recognize DTS files with this header information still attached. I encoded a 7.1 test stream for someone else on the forum, and a member discovered the problem when trying to use eac3to on the file. The files are here: http://www.sendspace.com/file/mz71xx There's a DTS-HD High Resolution stream (I don't see this used very often, basically DTS that can go up to a 3mb bitrate), and a DTS-HD Master Audio stream included. Thanks, Rik |

Quick question about eac3to and audio delay in Matroska files: The other day I ripped a DVD and then muxed it directly to Matroska without re-encoding, planning to encode it later. I checked the audio delay with DGIndex before muxing and applied the proper delay at mux. eac3to, when run without any options against the Matroska file, reports the audio delay as -301 ms. This sounds like too much of a delay, but off hand I can't remember what the audio delay reported by DGIndex was. Does anyone know how accurate eac3to's parsing of matroska delay values is?
Eduit: Mkvinfo -v shows that the audio starts 16ms after the video, which jogs my memory and I think was the delay I applied at muxing. What's going on here? Last edited by Inspector.Gadget; 25th March 2009 at 20:49. |

In this sense i think Madshi didn't use a "Ultra" level to do a speed/compression balancing. But in my case (and i think in other cases too at this point), 500 megs smaller are more than a weight difference. |

If you de-compress the flac files produced by eac3to and SoundOut are the resulting wav files identical? |

The resulting flac files were (very nearly) the same size. Perhaps there's a problem with SoundOut? It's not truncating the output file is it? I know that the flac CLI encoder can't cope with large files. Last edited by TinTime; 26th March 2009 at 18:59. Reason: Typo |

There's more to this than I thought. Apparently the header info is different sized depending on the type of DTS file you've encoded... The header includes the 8 bytes following the string STRMDATA, that seems to be consistent with all the files I've encoded so far. Rik |
