Would it be very difficult to reproduce the correlating commandline(s) for aften.exe? Of course only if it comes along with reasonable expenditure. I donīt want to waste your time. greets LTJ |

DTS extraction questions
Hello
I am trying to get a DPL2 downmix from a VOB DTS track. For example I have DTS encoded music DVD that has individual music tracks (as chapters?). When I use the demux option it just pulls out one large dts track which when downmixed gives me one large file. Is there a way to extract the audio track based on the video indexes or am I missing something easy? Great tool, can't wait to get into the lossless HD stff... Thanks.

Disney's "The Game Plan" has 92 streams, 00000.m2ts through 00091.m2ts.
Running the command eac3to works, but when I try and add the files, either 2) or by listing the all the files with '+' between them (used a spreadsheet), the program gets stuck. Does nothing. Perhaps 92 is more pieces than eac3to can handle? EDIT - It works after about 5 minutes. Had to get a cup of coffee, then I saw the results. Yeah! |

Moreover, as I already mentioned, the bitrate remained about the same at ~5000kbps, only the filesize shrunk dramatically. 5000kbps is a pretty normal bitrate for a flac encoded 24bit 48kHz 5.1 track that contains music (not for movie tracks). Is there anything else I can do to make sense of it all? |

So was the end result just fine? I imagine you must have had a pretty long list of audio overlaps!! Quote:

That bitrate number has no meaning whatsoever. I'm not even sure what number 5000kbps is supposed to be. I mean a 24bit 48kHz 5.1 PCM track has a bitrate of 6912kbps. So if the bitrate is meant to describe the decoded PCM track it's wrong. And if it's supposed to describe the FLAC bitstream then it's wrong, too, cause there's no way that a 3.7GB has nearly the same bitstream bitrate compared to a 1.7GB track of the same runtime. If you think about it, that just doesn't make any sense... |

EDIT: I'm beginning to think that this project might not be possible to implement because it would probably entail the mods actually having to break up a lot of posts into separate posts for the separate threads . Last edited by saint-francis; 31st May 2008 at 19:08. |

Don't know how complicated they are. Do you have a sample? Do you also have information about the file format? Quote:
(1) runtime (2) bitrate Slowing down an AC3 stream increases the runtime, but only very slightly. So file size increases also very slightly. If you have a 50% size increase then obviously the bitrate you used for the new encoding is about twice as high as the bitrate of the original file. eac3to always uses 640kbps for new 5.1 encodings. If you want to save space you can force eac3to to use a lower bitrate - of course that goes on the cost of quality. |

As well as 2.0?
While I'm here, is there any possibility of adding some kind of error skipping switch? Would be very welcome for those that try to reencode badly authored streams. Last edited by Snowknight26; 1st June 2008 at 21:39. |

By accident I selected the wrong stream today, which was a VC-1 video stream, and eac3to said it couldn't recognize the video stream. Which is okay with me, as I use it for audio conversion only, but if it can't handle VC-1 stream, I guess I won't be using it for video then. :)

eac3to is unable to demux MP2 audio from .ts

If you accidentally chose the VC-1 stream (instead of an audio one, let's say) then you did something wrong, not eac3to. Post the log and don't jump into conclusions like "eac3to can't handle vc-1". What all these people using eac3to with vc-1 streams would think of you? |

But seriously, I didn't mean to offend the eac3 folks: it's a heck of a good program, even if you only use it for audio.
