mkvtoolnix (Matroska toolkit): new release

[mikeson]

@Mosu:

Does mkvmerge/mkvextract support MP4/AAC tags when storing AAC into MKV (especially replaygain tags)?

In my case, when I try to mux replaygained/tagged AAC/MP4 into MKV and then extract it back, it has no replaygain tags.

BTW great tools, thanks a lot! :)

Nope. I have no idea how these tags look like, nor do I have sample files with such tags.

[mikeson]

@Mosu:

There are two replaygain tags: replaygain_track_gain and replaygain_track_peak. More info can be found here (http://replaygain.hydrogenaudio.org/)

I can upload you some samples somewhere or you can easily create some yourself with foobar2000 (Open AAC/MP4 -> RMB -> Replaygain -> Scan per-file track gain).

What I meant is I have no clue how tags are stored in QT/MP4 files.

Upload would be nice (FTP: mosu.no-ip.com, u/p "upload"/"only") 'cause I usually don't use Windows. Thanks.

just a couple vob sud id and I should uncheck all the others vob sub id one by one :(

I have another cosmetic idea for the GUI. I guess that most people use the input tab that way: select a file, select the track (in most cases just one track per file), set the language and optionally other tags. My idea: perhaps you can make some kind of automatism that way that mmg automatically selects the first track when selecting a file & jumps to the language field.

The same could be applied to chapter editor tab jumping to chapter name when clicking a chapter (the most frequent used field I guess).

Duely noted. I can definitely implement the latter (the auto focus/auto selection thingy), and I'll think of something suitable for the 'deselect all' thiny as I'm not sure yet whether I want a context menu or not. So far I don't have any, so either I'll move some more stuff into context menus or I'll have to find another way.

One more thing for chapter-editor: Could you enable it to save back to ogg-like-txt as well. Because for XML I cannot write simply " & <>, ubt have to use synonyms. Or perhaps MMG can transform them automatically to XML-like words?

Ah yes, that's a bug. I'll correct it, thanks.

Mosu,

This is going to be very very early feature request. But I can bet this will be asked in near future.

Q:Is it possible to implement mp4 -> mkv transmuxing (Nero digital or any other), just like doing RV9 in to mkv. The advantage I can see is to add chapter info and subtitles with these mp4. Now the added subs and chapter info can only viewable in Nero Show Time. (Which is atually a **** player). If it is converted to mkv then all other features of mkv can be utilised and simultaneously the eficiency of NeroDigital Codec.

What is your opinion. And i'm happy to know your decision, favouring or not.

Thanks.

This is definitely near the top of my 'things I want to implement next' list. But it's a "big" change compared to some other stuff, and I'm already working on a "big" change at the moment: unpacking of packed bitstream (meaning that B frames will be separated from the other frames they're attached to when reading AVI and sometimes badly created MP4 files; dummy frames will be removed). Unfortunately this is not as easy as we have hoped, but hey, things seldom are, and to quote Sheridan: "The universe doesn't give you any points for doing things that are easy."

So yes, I will come around to it, but it'll be some time until then. When I do come around to it the first thing I'll probably add is transmuxing the video. All additional info (chapters, subs) will probably come later.

Thanks you mosu :D, I don't even have words to praise you.:rolleyes: :thanks:

[Rash]

Damn! I've finally had time to make a full rip, test XviD beta 2 and test new Matroska features. And it works so fine! So sweet! ;) Thank you Mosu, thank you Gabest and all others who did it.

Just one thing. I've read this topic entirely, all pages. But somewhere by end I got a bit lost. How is the vobsub muxing now? I mean, in the first pages I read people were having problems showing their subtitles. Now I've noticed Mosu released a new version for mkvtooknix, Gabest released a new version for VSFilter (once again, thank you guys). So, were all those problems solved?

In my test I made a vobsub with 2 languages, english and portuguese. I muxed it (with latest mkvmuxer) and I could successfully playback the muxed file on MPC (with both its internal and Splitter 1.0.1.9) with the subtitles too. But in my case only portuguese sub will show up. If I choose to display the english one it won't render. Like I said, I'm using all latest filters.

Well, this is not really a request for help. As you can notice I haven't given any further information like mkvinfo -v log etc. I simply wanted to know if that was expected or if I was supposed see the english subs too. And I also wanted to say thank you guys for doing such great programs. :)

The only remaining problem that I'm aware of is that subs will not show/might not show if the .idx file contains "custom colors: ON" (read Liisachan's posts on http://forum.doom9.org/showthread.php?s=&threadid=64548&perpage=20&pagenumber=7). But then again, I don't watch movies on Windows, so this information might be outdated :)

[Rash]

Well, that's not my case. :(
Thanks a lot Mosu.

Being able to transmux bad AVI > Native MP4 in MKV will be a great addition for Matroska, and open source as well :). Reading of video from MP4 will be very useful also. Good luck on that Mosu, looking forward to it.

Jesus! Just found my problem! So sweet! Thanks a lot guys, once again. ;)

Out of curiosity: what was the solution?

Problem with English subs only. ;) That problem was in the movie as well, so I shouldn't really expect it to work as VobSub, hehe. :)

I have some bug reports about mp4 from others as well, but there's nothing I can do until I'm back home (around the 27th). Well, I CAN build a fixed Linux version, just no Windows version ;)

Merry christmas to everyone btw.

[Mosu]

ookzDVD, could you please upload a sample MP4 file that mkvmerge chokes on to my FTP server? The address is mosu.no-ip.com, user/password "upload"/"only".

Thanks.

@Mosu

Can you put a checkBox in the "Set Values" Botton on the Chapter Editor, to set/use Default Values?
Because i use R4R to make the chapters file and after that i use mkvtoolnix to edit them! Unfortunatly chapterXtracter don't suport XML chapters :( YET!!!

Thanks in advance Mosu!

[[Toff]]

I'm not sure it's needed but if you want XML support here it is :) (to place in your ChapterXtractor.ini)

Preset 7=Matroska XML
Format 7=%sp%sp%sp%sp<ChapterAtom>\n%sp%sp%sp%sp%sp%sp<ChapterTimeStart>%hh:%mm:%ss.%ms</ChapterTimeStart>\n%sp%sp%sp%sp%sp%sp<ChapterDisplay>\n%sp%sp%sp%sp%sp%sp%sp%sp<ChapterString>Chapter %c</ChapterString>\n%sp%sp%sp%sp%sp%sp%sp%sp<ChapterLanguage>eng</ChapterLanguage>\n%sp%sp%sp%sp%sp%sp</ChapterDisplay>\n%sp%sp%sp%sp</ChapterAtom>\n
Header 7=<Chapters>\n%sp%sp<EditionEntry>\n
Footer 7=%sp%sp</EditionEntry>\n</Chapters>\n


But IIRC mkvmerge can use OGM format too.

[pixolex]

:) I'll try it!!!

Merci TOFF!!

[pixolex]

Well :( some problem here...

First: chapterXtractor makes a .txt file...but not a problem i rename it to .xml file...

Second: When i try to open it in mkvtoolnix it says: "Unknown file format for "chapters.xml". It does not contain a supported chapter format"

:( desolé...

[Mosu]

Originally posted by pixolex

Neither mkvmerge nor mmg care about the extension. No need to rename it.

Second: When i try to open it in mkvtoolnix it says: "Unknown file format for "chapters.xml". It does not contain a supported chapter format"

mkvmerge looks for the string "<?xml" at the very beginning of the file, so you should change what toff proposed to...

Header 7=<?xml version="1.0" encoding="UTF-8"?>\n\n<Chapters>\n%sp%sp<EditionEntry>\n

(I hope that app writes UTF strings, otherwise you might have to adjust the encoding.)

[pixolex]

:) Now it works!!!

Thanks MOSU!!!

But all the chapters came with "eng" language...

Can't you make some thing like select all the chapters with "shift" or "Ctrl" key and update all the chapters selected at the same time with the "set values" botton!

:)

Edit:

:o now i see that part "<ChapterLanguage>eng</ChapterLanguage>", i can change it with my hands :o

But if you can do the shift and ctrl thing...;)

[Mosu]

Originally posted by pixolex

The "set values" button works recursively, meaning that if you select the very first node in the tree control and then hit "set values" you'll apply the values to all of the node's children.

[pixolex]

didn't know than sorry :(

Can you add that information in the hint for the set values botton... :)

Thanks for your fast responses and your interest!

[Mosu]

Originally posted by pixolex

It is already present:

b_set_values->SetToolTip("Here you can set the values for the language and "
"the country that you want to apply to all the "
"chapters below and including the currently "
"selected entry.");

[pixolex]

sorry :o

Now i understand the word BELOW..it refers to below the parent...or all chapters inside the parent node...

@Mosu @ forum,
Merry Xmas and "near" Happy New Year 2004.

@Mosu,
I was not able to send the NeroDigital .mp4 to your site,
since the NeroDigital will not allow to encode lower than
32Mbyte. Due of my limited upload bandwidth, so I can not
send the file. Hope you can get from other.

Thank you.

Hmm, interesting 'feature' ;) Anyway, someone else on IRC said he had problems with MP4 created by Nero Digital, too, but the test file he sent me worked fine for me, and he couldn't reproduce it either. So just to make sure that your bug is still present please download and try the latest build: http://www.bunkus.org/videotools/mkvtoolnix/win32/pre/mkvtoolnix-0.7.9-build20031228-2.rar

@Mosu,

I still have problem with that build, when I 'add' the NeroDigital
.mp4 use mmg, there was an error popup :

'mkvmerge -i' failed. Return code: 2
Error: Quicktime/MP4 reader: Invalid chunk size 7 at 228

PS. I'll send you the file since I just found how to make it
< 32Mb :)

Btw,
I did test too mux the VP6 .avi + Nero .aac + Vobsub .idx,
+ somes jpeg and rtf attachment.
when I played the result .mkv, the subtitle is somehow is gone
even I can find it with MatroskaProp.

The same movie but use RV9 .rmvb + Vobsub .idx everything is going
fine :)

Nice :) In Quicktime/MP4 each chunk is started by two four byte identifiers - the chunk type and its length. The length includes these two values, so a lenght < 8 is normally bullshit/broken. But maybe something else went wrong before this happened, so I appreciate your sending me a sample file.

Hmm... sounds like a playback problem if MatroskaProp says that the track is present.

Heya guys,

I've released a new version of mkvtoolnix: 0.8.0. It is mainly a bug fix release containing a number of small bug fixes (there was really no show stopper this time ;)) but also support for the new and simpler tagging system (still no tag editor, but it'll come soon). I suggest you read the ChangeLog below ;)

As a side note to those interested: This release does already contain code to create native MPEG4 files with proper B frame support and stuff, but due to various reasons this code is not activated by default. It'll come later. When I've got this working more or less then I'll probably
start workingon reading video from MP4 files.

The URLs:
http://www.bunkus.org/videotools/mkvtoolnix/
Sources:
http://www.bunkus.org/videotools/mkvtoolnix/sources/mkvtoolnix-0.8.0.tar.bz2
Windows binaries:
http://www.bunkus.org/videotools/mkvtoolnix/win32/mkvtoolnix-0.8.0.rar

Happy new year.

Here's the ChangeLog since 0.7.9:
---------------------------------
2004-01-01 Moritz Bunkus <moritz@bunkus.org>
* Released v0.8.0.

2003-12-29 Moritz Bunkus <moritz@bunkus.org>
* mmg: bug fix: Fixed the "write chapters to Matroska file" feature.
* mmg: bug fix: Made mmg not abort but only display an error message when malformed XML chapter files should be loaded.

2003-12-28 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: bug fix: The timescodes for Vorbis were calculated one packet too early (meaning that the first packet did not start at 0).
* mmg: Made "don't link" ON by default because some players might have problems with the second and all following files if they don't expect them not to start at 0.
* mkvmerge, mkvextract, mkvinfo: Added support for the new tagging system.
* mmg: bug fix: The default values for the chapter language and chapter country are now applied when loading simple (OGM) style chapter files as well.
* mkvmerge: bug fix: The VobSub packetizer will assume MPEG2 if no MPEG version identifier was found ("Unsupported MPEG version: 0x00...").

2003-12-23 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: There are MP4 files that actually contain HE-AAC but don't have the 5 byte identifier. mkvmerge will also assume SBR if there's only the 2 byte identifier with a sampling frequency < 44100Hz.

2003-12-22 Moritz Bunkus <moritz@bunkus.org>
* mkvextract: bug fix: Wrong display output and illegal memory access when extracting FLAC files.

2003-12-17 Moritz Bunkus <moritz@bunkus.org>
* mmg: bug fix: If one added a Matroska file and the track name or language of a track consisted of only blanks then mmg would segfault.

2003-12-15 Moritz Bunkus <moritz@bunkus.org>
* mmg: The input box will automatically select the first track when a file is selected. Upon track selection the input focus is set to the track name input box.
* mmg: The chapter editor automatically focuses the chapter name input box whenever a chapter entry is selected.
* mmg: bug fix: The chapter editor did not properly escape the chapter names resulting in invalid XML files if the special characters &, < or > were used.

2003-12-12 Moritz Bunkus <moritz@bunkus.org>
* mkvmerge: bug fix: If splitting was active then a wrong CodecID was written to the second and all following files for MP2 tracks.

Just so you don't get your hopes up, here are some of my notes about the current state of native MPEG4 framing.

The problem: VfW (Video for Windows, the infamous legacy interface that so boldly assumes that for each frame you put in you also get one out) forces developpers to play tricks with B frames. One approach is to put frames in coding order into a file, packing the bitstream (meaning putting more than one frame into a chunk) and using dummy frames so that the number of frames in equals the number of frames out.

Let's take the most famous example of B frame usage: a sequence of four frames, an I frame, two B frames and a P frame (display order!). These are written in coding order: IPBB. The problem is that for the P frame the decoder cannot give a frame back, and for the last B frame it would have to give two frames back.

In AVI this sequence might be stored like this: (I) (PB) (B) (p). This means that the second chunk contains two frames, and that the fourth chunk contains only a dummy frame.

If no native framing is used then, assuming 25fps, these four blocks will be kept as-is and timestamped (I 0ms) (PB 40ms) (B 80ms) (p 120ms). However, these are not the presentation timestamps of the respective frames.

Native framing will now do three things: Put each frame into one block, remove all dummy frames and re-calculate the timestamps to be presentation timestamps. The frames will still be stored in coding order, resulting in the following layout: (I 0ms) (P 120ms) (B 40ms) (B 80ms). This is what mkvmerge can do now.

However there are some limitations as I haven't tested it all that much. One is that mkvmerge will not accept such files as input files. The next is that due to some bad copy'n'pasting from all the developpers the CodecID that we want to use (V_MPEG4/ISO/ASP) actually reads V_MPEG4/IS0/ASP in all apps but mkvmerge - the difference is O = o vs 0 = zero... More issues that I haven't tested at all are splitting with this native mode, external timecode files, and basically what it does with files that don't even contain B frames.

The next problem is that the current playback applications do not really handle these out of order timestamps all that well. As far as I know only the ffdshow filter can play it back properly allthough its FPS information and stuff is all over the place while XVID chokes on such files. mplayer itself ain't to fond of these frames either, so I have to write a workaround for that (meaning I'll re-order the frame timecodes back to what they would be without native framing, but that's a limitation of mplayer's core).

All in all I can say that the 'big problem' is that the current multimedia architectures are not really ready for proper B framing including proper presentation timestamping. All these points are reasons why I haven't activated the code by default.

[ookzDVD]

@Mosu,

finally I can manage to send the NeroDigital .mp4 file to your ftp,
I hope you can find the problem.

Thank you.

1) Has anyone tried muxing idx/sub files for which he had changed the colour using "custom colours"? I tried that and although the muxing seemed to be successful the file I got played fine in MPC but no subs appeared! I did the muxing again with no custom colours in the idx this time and the file worked flawlessly. Maybe there is a bug in mkvmerge when the custom colour option in idx is chosen or maybe I had some bad luck with my file there...

2) I use mmg to mux rmvb (rv9 video + cook audio) with idx/sub subtitles and an ogg chapter list. Every version I had been using up to 0.7.8 was working fine for me up to now. I used 0.8.0 this time and it allways crashed when the muxing was about to begin. I downgraded to 0.7.8 and it worked ok again...

That string 'custom colors' is part of the text that mkvmerge just copies to the file. I'm 100% sure that it ain't a but in mkvmerge but in Gabest's filters.

I experienced the same problem before when I was trying to make original idx/sub files (See my post and Mosu's answer (http://forum.doom9.org/showthread.php?s=&threadid=64548&perpage=20&pagenumber=7) ). I hope the nature of this problem will be identified and fixed, too. Personally, however, this problem is not that important any more, now that you can create idx/sub files as you like from SSA (i.e. with custom font-family, custom font-size, custom font-color) using son2vobsub (http://www.anime.cz/s2v/) .
If you are trying to create original idx/sub's try son2vobsub. This is really great, and works fine with MKVToolnix.

As a side note, the top item in my wish list now, is font-embedding :)

Should again be Gabest's responsibility ;) His Matroska splitter would somehow have to make use of attached fonts e.g. save them in a temporary directory, and his VSFilter would then have to use these.

Found the problem and fixed it. The thing was that I had misinterpreted the Quicktime specs (MP4 is basically Quicktime), and therefore the atom size wasn't read correctly in a special case. Please download and try http://www.bunkus.org/videotools/mkvtoolnix/win32/pre/mkvtoolnix-0.8.0-build20040103-1.rar

I downloaded the latest build (20040103) and tried the muxing combination I mention in my previous post but with AAC audio. The muxing seems to be done ok but the resulting file freezes MPC. If I try the same muxing with 0.7.8 version the file plays perfectly!

[jk888]

This issue appeared in the subtitles forum:

"I think his problem is with muxing the vobsub subtitles into a mkv file. I have the same problem as well, everytime I use mkvtoolnix to mux vobsub subtitles there's a random chance it will crash, some pop-up message saying "failure writting to memory 00x7000..." something along those lines. Memory leaks maybe? I've been having that problem since v0.7x to the current v0.80, but it still doesn't get fixed.

Should I post this into the mkvtoolnix development thread?"

Anyone else having this problem?

A lot of people have this problem, but so far I haven't been able to reproduce it. Therefore I need sample files. If you all could please upload VobSubs for which mkvmerge crashes then I could fix this sooner. My FTP server is always open: mosu.no-ip.com, user "upload", password "only". And please also upload a text file with some description and your name/nick name so that I can know who uploaded which file.

I tried again today with files from a new encode and the file worked fine! So I guess either something was wrong with theese files or something with my pc... Anyway everything works fine now with the latest build!
