http://haali.net/mkv/codecs.pdf That PDF shows that for the CodecID "V_MS/VFW/FOURCC" the CodecPrivate data contains a "BITMAPINFOHEADER" structure which is an official win32 structure. The field "dwCompression" of that structure contains the "FOURCC" which tells us which codec is actually contained in this track. You can find a list of valid FOURCC values here: http://www.fourcc.org/ http://msdn.microsoft.com/de-de/libr...px#fourcccodes Valid FOURCC values are e.g. "avc1", "H264", "X264" for h264 streams and "WVC1" for VC-1 streams. So if the MKV CodecID says "V_MS/VFW/FOURCC", we have to look at the FOURCC value stored in "((BITMAPINFOHEADER) CodecPrivate)->dwCompression". |

Yes foobar2000 can split based on cue sheet, it's just such a pain to manually create a cue sheet. The cue sheet isn't complex just the conversion of milliseconds to frames is a little time consuming. Actually an option to output a cue sheet from eac3to would take all the pain away. http://wiki.hydrogenaudio.org/index.php?title=Cuesheet Performer, title and track names aren't really important since we need to tag the resultant flac anyway. "FEATURE" , "FEATURE ARTIST" and chapter numbers for track names would suffice. If you don't see value in it, I'll right a program to convert your chapter files to cue sheets. Thanks, Jeff |

I'm trying to remux an MKV I created with an earlier version of eac3to which still contains pulldown information. This is the error eac3to throws:
Code:
eac3to v3.06 command line: eac3to "Ray 1080p VC-1 English.mkv" 1: video.mkv 2: english.dts ------------------------------------------------------------------------------ MKV, 1 video track, 1 audio track, 2:32:20, 24p /1.001 1: V_MS/VFW/FOURCC/WVC1, English, 1080p (16:9) "Video 1080p VC-1" 2: DTS, English, 5.1 channels, 24 bits, 1510kbps, 48khz "Audio English DTS 5.1 1536kbps" [v01] Video tracks with unknown parameters can't be muxed to MKV. <ERROR> [v01] Internal error - unknown video output format! <ERROR> Is this a bug or intentional misbehavior? |

Madshi, though you say you plan on adding chapter and subtitle demuxing from mkvs, you didn't mention attachments. Any plans for those?
Also, doing anything with eac3to over a network share seems to be really slow. I'm remuxing an mkv and eac3to uses 0% CPU usage 90% of the time. It spikes up to about 10% for a fraction of a second... same with the network usage graph. Quote:

I suggest to madshi don't put the bitdepth of the source with standard DTS and DTS HR because this data is misunderstand (and irrelevant).

Hi guys,
just wondering if there's any difference in this workflow (other than efficiency of passes/typing/processing involved) for a BD title with a VC-1 video stream... Up until now, I've just been using:- eac3to L: 1) -demux, followed by eac3to video.vc1 video.mkv to demux and then put/house the demuxed .vc1 'raw' output into a more useful .mkv container for graphedit to use for frameserving (via Haali Media Splitter, WMVideo Decoder DMO) however, I'm curious to know if that would produce *exactly* the same video result (frame-for-frame) as, e.g. (assuming track 2 is the video in question):- eac3to L: 1) 2: video.mkv would the first 2-step method lose/discard any important information (frame-rate, etc) that the original container used to define the .vc1 stream? I have read that a raw .vc1 stream is somewhat dependent on its container to fully specify it, so I'm worried that a 2-step process would be lossy in some way? I do notice this in the output of the 2nd step (again, if using the initial 2-step process):- VC-1, 1080p24 /1.001 (16:9) Muxing video to Matroska... Added fps value to MKV header. ...so the .vc1 file must have retained some of the original attribute information in some way? I'm just not knowledgeable enough to know if there's going to be any difference between the methods here! cheers, m |

do I still need to use vc1conv when eac3to demuxes an HD DVD? I am converting some to bluray....I notice that the EAC3to dialog says "Removing VC1 pulldown". Does this mean I do not need to run vc1conv on the VC-1 video?
thanks |

You don't need to. eac3to will remove the pulldown.
I'd suggest just ripping from the disc to an MKV, and then using that as a source for TSMuxeR. ~MiSfit

Is it possible that eac3to reports the wrong information in regards to 1080p or 1080i? I have a BD that says 1080i on the back... which is odd, however eac3to and tsMuxeR both report 1080p. I trust eac3to more than what's on the back cover.

Here's another silly sample for you, Madshi (20mb cut of source AC3)
http://www.megaupload.com/?d=NQF6AX7M This one is the 3.1ch 640kbps AC3 track from the BluRay release of Bubble. eac3to complains about encoding it down to a 2ch AC3: Code:
J:\Bubble>eac3to Bubble.ac3 2ch.ac3 -down2 -192 AC3, 3.1 channels, 1:13:27, 640kbps, 48khz, dialnorm: -27dB Disabling DRC for Nero (E-)AC3 decoding... Removing AC3 dialog normalization... Decoding with DirectShow (Nero Audio Decoder 2)... DirectShow reports 3.1 channels, 24 bits, 48khz The AC3 encoder received a non-supported data format (pcm, 4, 24, -). Aborted at file position 352593920. Thanks! ~MiSfit

I am having problems with eac3to finding and using the Nero 7 DD decoder. Initially -test would show it had found it but every time I would run a job to extract the DD track from a eac3 track, it would die in some random place in the file. I have had to use -libav to complete the processing.
Installed the latest update to Nero 7 7.11.10 and how when I run -test I receive the following message\ Nero Audio Decoder (Nero 7) is not working correctly http://www.nero.com/eng/store-blu-ray.html Nero works fine since I am able to use Nero Vision to playback a .ts file with h.264 video and DD 5.1 audio Not entirely sure what to do now. If I continue to use -libav what sonic compromises, if any, am I having to make? Thanks |
