mkvtoolnix 1.4.0 is out with everything you want

[Mosu]

Hey,

finally: I'm releasing the new mkvtoolnix version including all the fancy new stuff. It's v1.4.0.

So what has changed? Tons of new features, tons of bug fixes, tons of new bugs ;) The more important things are:

- support for MPEG-1 and MPEG-2 video read from PS and ES streams,
- support for AVC (aka h.264) video from MP4 files,
- support for concatenating files,
- support for the new elements needed for menus,
- support for WAVPACK4 lossless and lossy audio,
- support for extracting VobSubs and
- added an online help to mmg accessible by pressing F1

Beginning with 1.4.0 I also provide both a Unicode enabled version and a non-Unicode version of mkvtoolnix. The usual: users of Windows 95, 98 and ME have to use the non-Unicode version. The others can use the Unicode enabled version.

The usual links to...
...the homepage:
http://www.bunkus.org/videotools/mkvtoolnix/
...the source code:
http://www.bunkus.org/videotools/mkvtoolnix/sources/mkvtoolnix-1.4.0.tar.bz2
...the Unicode enabled Windows binaries:
http://www.bunkus.org/videotools/mkvtoolnix/win32/mkvtoolnix-unicode-1.4.0-setup.exe
...the non-Unicode enabled Windows binaries:
http://www.bunkus.org/videotools/mkvtoolnix/win32/mkvtoolnix-1.4.0-setup.exe

My binaries for Fedora Core and SuSE as well as links to binaries for other systems are available from the homepage.

Now to the ChangeLog. It's not the ChangeLog since 1.0.2. Instead I'm listing all entries that are unique to the 1.4.0 line and have never appeared in the 1.0.x line:

-----------------------------------------------------------------------
2005-02-26 Moritz Bunkus <moritz@bunkus.org>
* Released v1.4.0.

2005-02-19 Moritz Bunkus <moritz@bunkus.org>
* mmg: new feature: The "default track" checkboxes are set properly when a Matroska file is added.
* mmg: new feature: Added a warning right before the muxing starts if the chapter editor contains entries but no chapter file has been selected (can be turned off).

2005-02-11 Moritz Bunkus <moritz@bunkus.org>
* mkvextract: new feature: Added VobSub extraction based on Mike Matsnev's code.

2005-02-08 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: bug fix: Track names could not be set to be empty.

2005-02-02 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: new feature: Use the posix_fadvise function on *nix systems. This results in a considerable speed up for the whole muxing process. As the function call seems to be buggy on at least Linux kernels 2.4.x it can be disabled completely during configure. It will only be used on Linux with a kernel from the 2.6.x series or newer.

2005-02-01 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: bug fix: Empty video frames in AVIs right at the beginning were breaking the MPEG-4 aspect ratio extraction and caused problems in other parts, too.

2005-01-30 Moritz Bunkus <moritz@bunkus.org>
* mmg: bug fix: It was possible to create chapter entries with invalid or even empty language entries. Not only are those invalid, such XML files can also not be loaded by mmg.
* mmg: bug fix: Overwriting a chapter file did not erase the previous file. So if the previous file was bigger than the current chapters then garbage remained at the end of the file.

2005-01-22 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: new feature: Added some more possible formats for binary data in XML files besides Base64 encoded data: hex encoded and ASCII "encoded".

2005-01-20 Moritz Bunkus <moritz@bunkus.org>
* mmg: bug fix: The "stretch" input box tooltip was wrong. The resulting command line was broken, too.

2005-01-18 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: new feature: Hex values accept more formats (like optional white space between numbers or the "0x" prefix).

2005-01-15 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: Changed the AVC/h.264 timecode handling to include the timecode offsets from the CTTS atom.

2005-01-15 Moritz Bunkus <moritz@bunkus.org>
* mmg: Reformatted the HTML guide and updated the screenshots. It should be more readable for those whose desktop is not 1200 pixels wide.

2005-01-08 Moritz Bunkus <moritz@bunkus.org>
* mmg: new feature: Made the mkvmerge GUI guide available by pressing F1 or selecting "Help" from the "Help" menu.

2005-01-07 Moritz Bunkus <moritz@bunkus.org>
* mkvextract: bug fix: ASS/SSA extraction was broken in some rare cases.

2005-01-02 Moritz Bunkus <moritz@bunkus.org>
* mmg: new feature: Added support for mkvmerge's new "appending tracks" feature.

2004-12-31 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: new feature: Added support for reading the pixel aspect ratio from AVC/h264 video data.
* mkvmerge: new feature: Added AVC/h264 muxing from MP4.

2004-12-28 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: new feature: Added a MPEG PS demuxer.
* mkvinfo: new feature: Added a couple new elements (silent tracks). Patch by Steve Lhomme (see AUTHORS).

2004-12-27 Moritz Bunkus <moritz@bunkus.org>
* mkvextract: new feature: Added WAVPACK4 extraction. Patch by Steve Lhomme (see AUTHORS).

2004-12-18 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: new feature: Added WAVPACK4 muxing. Patch by Steve Lhomme (see AUTHORS).

2004-12-17 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: new feature: Added VobButton muxing. Patch by Steve Lhomme (see AUTHORS).

2004-11-18 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: Implemented concatenating files with chapters.
* mkvmerge: Changed the "progress" output. It's now correct for file concatenation, too.

2004-11-17 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: new feature: Concatenating/appending files is now possible. A lot of things aren't tested, and others simply don't work yet (chapter merging, duplicate tag elimination, proper progress report, support in mmg just to name a few), but the basic functionality seems to work.
----------------------------------------------------------------------

I'm well aware that there are probably new bugs. Also the concatenation code is not as well-tested as I'd like. But as always I'm grateful for bug reports and will try to fix those bugs as quickly as possible.

Have fun :)

Only for AAC-in-MP4 (because you can't detect HE on raw ATDS AAC files without decoding them). But that has been working for ages.

Hi Mosu,

whats the difference between the unicode and the non-unicode version?
Btw..I get an error when stating mmg.exe The Applictaion couldn´t start because of missing wxbase253u_gcc_custom.dll ...whats this for dll?

The idea is that you can safely use stuff like Japanese characters in all of mmg's input boxes. I haven't ever had anything else than a German or English Windows version, so I can't really tell what else is different.

Btw..I get an error when stating mmg.exe The Applictaion couldn´t start because of missing wxbase253u_gcc_custom.dll ...whats this for dll?

Sounds like you have only downloaded the .RAR but not the runtime RAR. Or you haven't extracted the runtime RAR into the same directory as the main RAR. Just get the installer instead (or uncompress both RARs into the same directory).

I'd like to but...

The URL you requested, /videotools/mkvtoolnix/win32/mkvtoolnix-unicode-runtime-1.4.rar, was not found. If you are looking for a current release of mkvtoolnix then please head over to the mkvtoolnix home page.

I know aac in mp4 is working but i would know if "raw ATDS AAC" could be possible (in a near future).


one question: for aac (he or lc) in mp4 the switch --aac-is-sbr is needed ?

Thanks again

Like I said: autodetection? No. You can use HE AAC ADTS files, but you have to use the --aac-is-sbr switch then.

one question: for aac (he or lc) in mp4 the switch --aac-is-sbr is needed ?

No. Only if the MP4 file itself contains broken data. So generally: no.

Congrats!

And about MMG (on my Windows 2000):

Hey!!! This is _really_ unicode-based! :D

The editboxes in MMG (or commandline copied to Clipboard) are now in UTF-16 and MMG is ok with Unicode filename, like a Finnish Korean mix, for input/output .... Awesome.

But hey, "the mkvmerge output" in the "mkv is running" box is in UTF-8, not UTF-16. This is not preferable (incoherent), altho the problem is just cosmetic...

And please fix the default extension to .mkv.
Now "save as foo" is defaulted to foo.mka.

thx for your great work!!

I still have this problem : if i remux a file which had chapters, and if i choose another chapterfil when i mux, with Haali splitter, i still can choose between 'Edition 1' and 'Edition 2' while playing the file, and each edition correspond to old and new chapters :s
If i check 'No chapters' in the muxgin window, i don't have ths 'bug'

[niamh]

Oh boy.......

Time warped and it's Christmas all over again :D

Correct, because I thought the old runtimes would be ok...the new ones I couldn´t download...but now its fixed and all fine ;)
As usual great work!

[niamh]

<rolls up sleeves...>

- 1st thing I did was press the big red button, aka F1..it says the help .hhp file is not found, and in fact it's nowhere on my pc.(I ued the installer And uninstalled the old one properly)

- then I started to append bonus files (wanted to do that for ages)..so I appended first the video tracks, then the audio tracks, then the subtitles ones, and remuxed the lot... it works and it's in synch! great. Is there any plan in the future to switch the audio along with the video and subs though (or can it be done in a way I missed)? Right now I must do it manually through the splitter.

- the resulting files won't seek either, tested with MPC and the Core, the slider keeps going back to the start, with or without freezing involved. (the players as well display only file 1's name, but that's obviously the players problem, they're in for a serious upgrading ;) )

- If I select a few files to append, mmg won't let me remove them, in case I got it wrong. It says the file cannot be removed as there are tracks that are supposed to be appended to tracks from this file. But whatever file you select, or even if you deselect all the tracks, it keeps spitting the error message anyway, so the only solution is to start a new project.

- As for appended chapters, I need to figure it out, because it keeps using the chapters from file 1, so I'm sure I missed something there.

- What are those edition thingies in haali's splitter? they seem to do nothing that I can see :)


Anyway, I'm impressed, as usual :). A big thank you.

(EDIT:I've just appended a full album of aac songs, and that seeks no problem, but the different tracks aren't detected, what did I forget this time?)

Doh, both installers are missing three files. I've updated them. Simply download one again and install over the old location. The RARs did contain the files.

Is there any plan in the future to switch the audio along with the video and subs though (or can it be done in a way I missed)? Right now I must do it manually through the splitter.

That's a player issue, and I can't comment on that :)

- the resulting files won't seek either, tested with MPC and the Core, the slider keeps going back to the start, with or without freezing involved.

Hmm, it works here for me, but I mostly test with mplayer/xine on Linux. I can only test so much with Windows running inside VMWare... But a quick test with bsplayer + Matroska Pack 1.0.3 as well as with Haali's latest splitter show no such behaviour.

(the players as well display only file 1's name, but that's obviously the players problem, they're in for a serious upgrading ;) )

Well, if you concatenate two tracks then the resulting file will only contain one track. Therefore you definitely only have one name for that track (and only one title for the complete file).

- If I select a few files to append, mmg won't let me remove them, in case I got it wrong.

Not quite true, but close enough. There's definitely a bug in how mmg adds the tracks when you press "append". The thing is that you can only remove files whose tracks don't have another track appended. When you "append" a file with more than one track inside then the tracks are inserted at the end resulting in the second track being appended to the first track of the same file. Therefore the file cannot be removed. However, you CAN move the first track up in the track selection. Then you should be able to remove that file.

Like I said, it's a bug.

- As for appended chapters, I need to figure it out, because it keeps using the chapters from file 1, so I'm sure I missed something there.

The goal is to have chapters of both files appended in the complete file as well. Meaning if file one contains two chapters and file two (the appended one) contains three chapters then the resulting file should contain five chapters.

(EDIT:I've just appended a full album of aac songs, and that seeks no problem, but the different tracks aren't detected, what did I forget this time?)

Like I've said above: appending tracks results in a single track for all tracks that are appended to one another.

The "Split by time" option is always greyed with the 1.4.0 version.

Damn... Happens only with wxWidgets 2.5.3 on Windows (meaning with the Unicode version). Dunno what I can do about it...

[Mosu]

http://www.bunkus.org/videotools/mkvtoolnix/win32/pre/mkvtoolnix-unicode-1.4.0-build20050227-1.rar

Contains a couple of fixes related to problems with wxWidgets 2.5.x on Windows ( = the Unicode build):

--------------------------------------------------------
2005-02-27 Moritz Bunkus <moritz@bunkus.org>
* mmg: bug fix: The job queue was not loaded on startup on Windows Unicode builds (another wxWidgets 2.5.3 problem).

2005-02-26 Moritz Bunkus <moritz@bunkus.org>
* mmg: bug fix: The job status in the job runner dialog was broken on Unicode builds on all systems.
* mmg: bug fix: "Splitting by time" was not selectable on Windows Unicode builds (problem with wxWidgets 2.5.3).
* mmg: bug fix: mkvmerge's output during muxing was not converted from UTF-8.
* mmg: bug fix: The default extension added when the user doesn't give one is different in wxWidgets 2.4.x and 2.5.x. It should always be .mkv and not .mka.
--------------------------------------------------------

Three of those five fixes were necessary because wxWidgets 2.5.x behaves differently on Windows than 2.4.x does.

[AnimalMother]

Halleluiah!

As always your work is awesome.

[ssjkakaroto]

thx a lot for your great work Mosu!

Like I've said above: appending tracks results in a single track for all tracks that are appended to one another.

Ok, I figured I could still navigate from subtrack 1 to others, like I'm doing for the video tracks I appended. :)

Well, if you concatenate two tracks then the resulting file will only contain one track. Therefore you definitely only have one name for that track (and only one title for the complete file).

Fair enough, but it's not the title I gave to the resulting file that appears, but the first one in the append chain.Is that normal (player issue I guess ;) )?

[Splashdriver]

Hi,

First of all, big thanks for the great efforts putting into this program. :D

For the very first time I've encountered a problem I never had before. When I try to add a videofile (.Avi or .MKV) it gives me an error:
File Identification Failed. Return Code 2.

It says something about 'no output file was given'
:confused:

I really hope I could get some help here. I'm on a windows XP machine btw. Thanks in advance.

What was the name of the file you wanted to add? Also make sure that mmg is not using an older version of mkvmerge. Have a look at the "settings" tab and check the location of the mkvmerge.exe executable.

You can't, and I'm pretty sure that you don't have two video tracks if you append two video tracks. But maybe we misunderstand each other.

Fair enough, but it's not the title I gave to the resulting file that appears, but the first one in the append chain.Is that normal (player issue I guess ;) )?

The priorities are:

1. If the title was given on the "global" tab then that one will be the final file's title.
2. If none is given then the title of the first file actually containing a title is used.

The same is true for track names.

Let's assume you have two files, v1.mkv and v2.mkv. v1.mkv contains two tracks, one video and one audio. v1's title is "first part". v2 contains the same type of tracks, and its title is "second part". Now you "add" v1.mkv to mmg and "append" v2.mkv. Then the "file/segment title" input box will automatically contain the title of v1.mkv, "first part". That you can change to something else. The resulting file will contain the title that was present in that input box.

The same is true for track names.

What any player shows (either the track name or the file title) as the "name" is up to the player though.

The file name I'm trying to add is 'Martial Arts of Shaolin.mkv'. Nothing unusual, I believe. I've checked and verified the location of the mkvmerge.exe executable. I've completely deinstalled all previous mkvtoolnix versions before installing the new one. I'm still getting the same error returned. I'm completely puzzled.

How should I verify that I don't possibly have a older version of mkvmerge running?

[Splashdriver]

I think I just switch back for a while. Thank you.

Indeed. File names with spaces are OK. Does this happen with other files, too? Could you try moving the file to another directory and adding it from there? Does it still happen then?

How should I verify that I don't possibly have a older version of mkvmerge running?

What's the size and date of the mkvmerge.exe that is mentioned on the 'settings' page?

Then start mmg, go to the "settings" tab, hit the "browse" button right to the "mkvmerge executable" input box and select the mkvmerge.exe that you've just extracted.

[Teegedeck]

I'm stunned, what a pleasant surprise! I'm gonna report back as soon as I get to try it.

Well, the first thing I did was to append 4 Young Frankenstein's bonuses that I have scattered around. From haali's splitter, I can switch directly to all 4 tracks (separately from chapters), and they have the name the original tracks had. Same goes for the audio and subtitle tracks. Sorry for being dumb :)



The priorities are:...
All clarified, I missed that in the manual.

When you "append" files with mmg then there's only ONE name for the track. When you "add" files then you have four tracks, each with its own name.

"append":
track1: <file1><file2><file3><file4>

"add":
track1: <file1>
track2: <file2>
track3: <file3>
track4: <file4>

I can't believe I added them instead of appending them .I'll go hide somewhere

MPC somehow doesn't want to use the Nero decoder when the container is an MKV and uses FFDShow instead, which results in a somewhat garbled screen and crashes on some seeking (sound is fine though). When I use Haali's splitter (disabling MPC's internal Matroska splitter) MPC says "cannot load any source filter".

I guess the MKV is fine and we'll have to wait till ffdshow handles AVC better or MPC manages to use Nero's decoding filter on MKV's.

You can't find any real information about this. Those elements are used by robux4's menu extraction application that will be the base for our menu experiments. Menus are not usable at the moment. What I've added was groundwork.

[thana]

first thx for this official release, it's greatly appreciated :)

some things i noticed until now:
[list=1] a cosmetic bug in mmg: the window-titles of the add- and append-file-open-dialogs are swapped

you mentionend already that the tracks are not sorted probably in mmg when appending. this gets *really* annoying when you try to append 7 files with 5 tracks each, i ended up spending 5 minutes just to bring them in the right order so i finally could hit "start muxing" without the error coming up. hope this gets fixed soon.

another related thing: appending files is possible without any files already added. and in this case it's not possible to remove them anymore (other than file->new), because there are no other files to remove first.

i managed to crash mkvmerge with an illegal operation (mmg stayed open but reported no error) when i tried appending files while at the same time splitting them again with same filesize. i can post the windows crash-report if you need it. after some more tests i found out that this only happens when input-filesize = output-filesize, in all other cases mkvmerge just exits with returncode 3 (mmg shows no error).

another more or less cosmetic bug: when splitting is activated mmg warns you to overwrite a file when the file in the "output filename" box already exists, even though it actually doesn't get overwritten because "-00x" is appended to the filenames.

when appending mkv's that where split with linking enabled, the times of the chapters of the 3rd+ file gets messed up.

maybe related: an mkv from appended mkv's that where split with linking enabled are not seekable anymore once you come past the time of first file. both haali's and gabest's latest splitters just hang while the time is running. it starts working again when you seek to times from the next appended file. after that it hangs again, and so on. looks like something is fishy with the timecodes here.

and another question: whats the status on native mpeg4? i played around a bit with --engage native_mpeg4 but only got warnings, errors, crashes and garbled output until now. should we report bugs on it?

that's it for now ;)
