That is correct. The reason this option exists is for Linux distributions to be able to build byte-identical packages of mkvtoolnix given the same library/compiler versions etc.

So is there a possibility to have the same option for mkv muxing? maybe mkvpropedit can be useful.
I'm trying to achieve this to be able to mux a file on a distant server where I have the same source file as the local ones, without needing to download it and view it (md5 sum checking) |

No, sorry. Quoting myself and others from a recent IRC session:

Understood, I will not beg for it since it will effectively result in strange file unless we can explicitly furnish custom UID for one specific mux for each track on other xml element
I will try to find third party tool which could perform a some sort of synchronization between two muxed file with same option, since the difference between the two would be very small (timestamp and segment UID) Perhaps, one small question that could help, is the difference between two mux is compressed in the header of the file or dispatched, well I guess I can do it myself, don’t bother. Thank you for your help |

The differences are indeed only in a very small number of elements, and those should always have the same size. Therefore syncing the two files should be nearly trivial. I cannot tell the actual elements off-hand, but they should be the various UID elements (track UID, segment UID, tag/edition/chapter/attachment UIDs), the muxing timestamp ("Date:" in mkvinfo's output), and (if you have two different sets of mkvmerge executables) the "writing app" element.
The position of these elements varies: most of them are located at the start of the file before the first cluster (track/segment/chapter UIDs, muxing timestamp, writing app). Others can be at the end of the file because mkvmerge puts them there (tag/edition/attachment UIDs). There are two sync tools I use regularly: rsync and unison. rsync is mostly a "from point A to point B" tool, and unison is a "keep two directory structures in sync and resolve differences" tool. Therefore rsync is better suited for this particular purpose. Both are available for various Linux/Unixy systems as well as for Windows, but my experience with them on Windows hasn't been that great. However, both run over ssh and only update those parts of a file that has actually changed making them incredibly efficient for huge files with small differences.

I have a question about the "--cropping" command.
Does it really tamper with the video stream by deleting specified number of macroblocks or is it just setting some kind of flag for the decoder filter to apply cropping during playback? |

The latter. mkvmerge is not an encoder/decoder, and the cropping parameters are only stored in the track headers. It's up to the decoding chain to honor them and use the appropriate filters.

I thought it could be interesting for other to see if it was trivial or not, well it is.
First thank you for the name of rsync Mosu, I already knew the name but I couldn't recover it, you saved me some time. Here is the result: - 6 mkv total of 4.09Go - Sent: 436Ko Received: 1.08Mo - Achieved in 4 min and 10 sec Limited by a slow P4@2.8ghz processor and done through a 100ko/s upload and 50ko/s download broadband restriction. - rsync effectiveness: 2774!!! Mkv made with same version of mkvmerge with identical batch and source files Made between a Windows XP and Windows 7 desktop, I didn't used rsync under cygwin but a modded rcync for windows called DeltaCopy (work good with mix linux/win server/client too) I knew it was an effective technique, but it has surpassed my expectation. |

Nice numbers indeed Ah yes DeltaCopy; I actually know that one but didn't think of it. Anyway, glad to see you've got a working solution.

mkvmerge cannot split by chapters (neither in current versions -- 2.4.1 is rather old, btw). It can split by timecodes, but you'll have to get the chapter start times manually and use them as the split timecodes.

Quoting the documentation for the "--split" option:

new feature: reading multiple VOBs
Hey,
I've implemented reading multiple VOBs that logically belong together as if they were a single big file. Here's the ChangeLog entry that should make clear what I mean: Quote:
This also means that mkvmerge will still detect VOB files from the middle of such a set as e.g. h264 instead of MPEG-2 if you decide to add e.g. VTS_01_3.VOB instead of VTS_01_1.VOB -- don't do that BTW: No, this of course does not mean that mkvmerge can read directly from encrypted DVDs. It does not contain decryption routines. Here's the link to the Windows build: http://www.bunkus.org/videotools/mkv...-193-setup.exe

Thanks again, what fixed the problems was one or more of this things:
1. remove the repo version (old one), mkvtoolnix + gui 2. install the debs (jaunty amd64): Code:
mkvmerge GUI v3.0.0 ('Hang up your Hang-Ups') built on Dec 12 2009 19:13:47 to admin: this was probably the wrong thread, posts: 1330-1333 + 1335 could make a cute lil thread named 'how would i split mkv to lil mkvs by chapters?' sorry about that...

No particular reason.

I tested on a dvd with more than one title, (vts_02_ ...) and it works fine. The change's I'd make is to state in the change log that this is tested only with dvd vob files, and an indication in mmg when adding the first file that it is also loading files +02 +03 etc. instead of the warning message.
