Matroska News

6. Juni 2005

Was gibt es Neues zu erz?hlen ?ber das matroska Projekt, au?er da? ich jetzt versuchen werde diese Seite hier in Zukunft auch auf Deutsch zu pflegen? Unser Teamchef, robux4, ist im Moment sehr stark damit besch?ftigt, unser neues Men? System in einen brauchbaren Status zu versetzen. Es wird sich sehr stark an das von konventionellen DVD's anlehnen, auch weil wir einsehen mussten da? wir mit den limitierten M?glichkeiten unseres kleinen Teams nicht in der Lage sein werden, einen guten Editor f?r Men?s selbst zu schreiben, und auf diese Weise vorhandene DVD Men?s in matroska files verwendet werden k?nnen.

Das Erstellen solcher files von beliebigen Quell-DVD's klappt bereits hervorragend, wir k?nnen diese komplett und mit allen Men?s und Funktionen in ein einziges MKV file kopieren, und dabei f?r die einzelnen Video/Audio/Untertitel Spuren bereits JEDEN derzeit unterst?tzen codec bzw. Format einsetzen. Dazu hat robux4 das tool DVDMenuXtractor geschaffen, welches bisher aber noch nicht ver?ffentlicht ist, und die F?higkeiten von mkvmerge wurden deutlich erweitert.
Was nun noch fehlt ist die M?glichkeit diese files dann auch abzuspielen, und all unsere ?berlegungen wie das auf M$ DirectShow, also mit dem Windows Mediaplayer, erreicht werden k?nnte haben leider zu keinem brauchbaren Ergebnis gef?hrt. Auch aus diesem Grund sind wir gerade dabei, uns ein neues tool namens ratDVD sehr genau anzusehen, welches mit dem Ziel entwickelt wurde eine komplette DVD mit allen Men?s in ein ZIP file zu packen das mehrere MPEG D! ateien in einer der DVD ?hnelnden Struktur enth?lt. Am meisten interessiert uns dabei das DirectShow Navigationsfilter das mit dem Programm verbreitet wird, und angeblich genau die ben?tigten Funktionalit?ten ?ber den Windows Mediaplayer 10 bereitstellt. Da dieses Filter nach Angaben seines Authors auf einer Linux Bibliothem namens libdvdnav basiert, der unter der GNU GPL opensource Lizenz gesch?tzt ist, muss der Author den Quellcode des Filters ebenfalls ver?ffentlichen, was wir sehr begr?ssen.

Bis das soweit ist arbeitet robux4 weiter mit Hochdruck an der Implementierung unseres Men? Systems in VLC, den exzellenten opensource Video-Player der Franz?sischen Videolan Gruppe. Dieser Player, der u.a. f?r Windows, MacOSX und Linux verf?gbar ist, hat schon sehr lange matroska Unterst?tzung, jedoch war dieser nicht auf den notwendigen Stand um darauf aufbauend schnell auch Men?s unterst?tzen zu k?nnen. Wir hoffen aber, da? diese Arbeiten schon bald abgeschlossen sein werden, damit wir unser Men? System endg?ltig vorstellen k?nnen.

Was hat sich in den letzten Woche sonst noch ereignet ? Nun wir mussten unser bekanntes matroska playback packf?r DirectShow player leider schon sehr bald nach Vorstellung der 1.1.0 Version ?berarbeiten und Version 1.1.1 vorstellen, weil sich dummerweise ein bug eingeschlichen hatte der Inkompatibilit?ten des neuen matroska splitter Filters von Mike 'Haali' Matsnev mit dem alten Splitter verursachen konnte. Ich bin im ?brigen neugierig, ob unsere Fans ?berhaupt bemerkt haben da? dieser Splitter auch MP4 files abspielen kann wenn man dies bei der Installation w?nscht ( normal deaktiviert ), aber evtl. sollten wir das gar nicht zu sehr an die grosse Glocke h?ngen, um zu vermeiden da? unser monatlicher download trafic total unbezahlbar wird. Das playback pack wurde mittlerweile mehr als 1 Million mal runtergeladen und es scheint als ob das grosse Interesse weiter anhalten w?rden, mit Blick auf die t?glich gezogenen Kopien.!

Die matroska Fans die den Container mehr f?r Musik-CD's zusammen mit Foobar2000, der freien Audioplayer Alternative zu WinAMP einsetzen ( es soll ja wirklich welche geben ), sollten sich mal das neue matroska plugin unseres Freundes Toff ziehen und in den 'plugins' folder des players kopieren. Es l?st eine Reihe kleinerer Probleme, wie z.B. die Anzeige der einzelnen Songs der CD ( die ja dann zu Kapiteln in einem einzigen file werden ), wenn diese mit neueren mkvmerge Versionen erstellt worden sind. Zudem wurde das Springen in matroska audio files (MKA) mit Vorbis audio verbessert, und die tags sollten jetzt auch alle korrekt angezeigt werden. Meines Wissens nach ist dieses neue plugin derzeit noch in keinem der offiziellen fb2k installer enthalten, nicht mal der fb2k Entwickler Case ist mit seine! r speziellen download Seite f?r die neuesten Versionen des players hier auf dem neusten Stand.

Ich denke mal da? das jetzt erst mal reichen sollte, mehr News gibt dann ( hoffentlich ) schon bald !

Auch wenn es im Moment nahc aussen nicht so aussehen sollte, wir sind ziemlich aktiv. Die Arbeiten am Men?system kommen gut voran, und wir hoffen in der n?chsten VLC Version ( 0.8.2 ) bereits Wiedergabe Unterst?tzung f?r dieses anbieten zu k?nnen.

In der Zwischenzeit haben wir eine neue Version unseres playback packs (v1.1.0) vorgestellt, welches mittlerweile schon ?ber eine Million mal runtergeladen wurde. Die wesentlichste ?nderung d?rfte die Umstellung des matroska Splitter Filters von Gabest's auf Haali's splitter sein. Au?erdem ist unser geliebtes FFdshow jetzt noch leistungsf?higer und unterst?tzt mehr codecs, so da? wir einige andere decoder Filter aus dem pack rausnehmen konnten. Hinzu kam ein Dekoder f?r Wavpack Audio files, ein neues Komprimierverfahren welches verlustfreie, normale oder sogenannte Hybrid ( normal + Korrekturfile ) von Musik erlaubt und dem wir eine grosse Zukunft vorhersagen.

6. Februar 2005

Neue Versionen von libebml (0.7.3) und libmatroska (0.7.5) wurden vorgestellt. Das Update wurde notwendig um die Basis f?r das kommende Men? System zu schaffen.

2. Januar 2005

Nein, wir sind NICHT tot :-) ! Das Projekt ist im Gegenteil gerade jetzt in einer sehr interessanten Phase, da wir schon sehr bald viele neue M?glichkeiten f?r den matroska Nutzer bereitstellen werden. Es ist zwar im Moment evtl. noch ein klein wenig zu fr?h dar?ber zu sprechen da einige erst halbfertig sind, aber hier ein kleiner Ausblick was schon bald m?glich sein wird :

MPEG 1/2 video Unterst?tzung : Die letzten Pre-Releases von mkvmerge (mkvtoolnix) erlauben ja nun schon seit einiger Zeit sogenannte MPEG Elementary Streams (ES) einzulesen, basierend auf John 'spyder' Cannon's MPEG parser Quelltext. Leider ist das bisher nicht gerade komfortabel zu nutzen, da die meisten MPEG files nun mal Program Streams (PS) sind und diese daher zun?chst mal ?ber tools wie z.B. TMPEGencoder oder bbdemux in ES umgewandelt werden m?ssen, bevor man sie mit mkvmerge in MKV muxen kann. Gerade daran hat Mosu nun sehr hart gearbeitet, erwartet f?r die n?chste mkvtoolnix Version Unterst?tzung f?r MPEG PS und sogar VOB files.
Men?'s: Wir k?nne nun dank der harten Arbeit von Teamchef Steve 'robux4' Lhomme's an seinem neuen Programm DVDmenuXtractor komplette Men?strukturen von DVD extrahieren. Es macht daraus ein XML file, welches dann von mkvmerge in den neusten Versionen verarbeitet werden kann. Das erlaubt es uns, eine kompleete DVD in ein einziges MKV file zu muxen, einschliesslich Video, Audio, Untertitel und Men? ! Das einzige Problem dabei ist, da? wir daf?r noch keinen player haben, ein release kommt daher noch nicht in Frage. Wir diskutieren daf?r mehrere M?glichkeiten, z.B. k?nnten wir das matroska CDL von TCMP (The Core Mediaplayer) umschreiben, den grossartigen Videolan player VLC anpassen oder ein spezielles DVD Navigationsfilter f?r alle DirectShow player machen. Die letzte Option w?re eindeutig die beste, weil damit alle ( oder die meisten ) DirectShow player das matroska Men?! System unterst?tzen k?nnten.
+ Wavpack 4: oh nein, nicht noch ein lossless ( verlustfreier ) audio codec, werdet ihr sagen. Das w?re aber ein wenig ungerecht, weil sein Author, David Bryant, diesem codec eine Reihe von features mitgegeben hat, die FLAC oder TTA nicht bieten k?nnen : +
- einen normalen ( verlustbehafteten ) Modus : zus?tzlich zum lossless Modus bietet Wavpack einen Kompressionsverfahren an, das zwar im Vergleich zu MP3 und Konsorten eine etwas h?here Bitrate verlangt, daf?r aber auch f?r Expertenohren ausgezeichnet klingt. Ohne die Sache komplizieren zu wollen, verwendet Wavpack in diesem Modus kein sogenanntes Psycho-Modell, d.h es werden nicht Teile der Musik ganz einfach unter den Tisch geworfen ( der codec 'entscheidet' dabei ob der Mensch das h?ren kann oder nicht ), wie das bei MP3 der Fall ist. Die Bitrate ist dadurch mit ca. 300 kbps zwar hoch, der Klang aber erstklassig.
- ein neuer 'Hybrid' Modus : Derart betrieben wird Wavpack4 gleich zwei files aus eurer Musik machen, n?mlich ein verlustbehaftetes mit hoher bitrate ( s.o. ) und ein sogenanntes Korrekturfile. Der codec kann dann das Originalfile ohne jeglichen Verlust aus den beiden Teilen wiederherstellen. Die Idee ist, das verlustbehaftete file auf ein portables Ger?t mit beschr?nkter Speicherkapazit?t ( z.B. PocketPC ) laden zu k?nnen, w?hrend das zugeh?rigeKorrekturfile zu Hause auf der Festplatte des Hauptrechners verbleibt. Zu Hause kann man dann 'lossless', also Originalqualit?t h?ren, und f?r den Portable spart man Speicherplatz ohne alles immer doppelt speichern zu m?ssen. Mit matroska k?nnen wir, der Einfachheit halber, beide Teile in einem MKA file speichern, und das verlustbehaftete dann ?ber einen schnellen Extraktionsprozess entnehmen um das Speichermdium des Portable mit neuer Musik zu laden.
+
Steve hat mkvmerge bereits mit perfektem Wavpack4 support ausgestattett, dies wird wohl ebenfalls mit der n?chsten Version 1.2.0 ver?ffentlicht werden.

There is a PERL parser for matroska files now, made by a user called Omion +on Hydrogenaudio.org. I don't expect that many people will download this +in its current phase (alpha), but you can find it on his website or in our SVN server. +You can find some background about the parser on Hydrogenaudio +in this thread.

Another very interesting tool was released from our old and dear friend +Christophe 'Toff' Paris, shortly before he went to another town to start +his new job here. This very useful tool is called MatroskaDiag +and will analyze matroska files and then check your PC if you have all the +right filters installed to play it with a DirectShow based player like Windows +Mediaplayer, or more preferably Zoomplayer +or TCMP. For interested developers, here +are the sources in Delphi. +Toff, from the whole matroska team, all the best for your +new job and your new life. We hope you will always be our friend, as we +are very proud to be yours.

Other news :

AvInfo and Gspot +have support for MKV files now. Both are video info tools, similar to VideoInspector +and MediaInfo. I couldn't test the +two new tools still, but knowing the authors and the quality of their tools +when i was using them for AVI files, i expect they did a good job.
Mosu has released the very latest version of Mkvtoolnix, 0.9.6 . More +about it here.

It has been a while since i had the time to write a long news entry, but +let me just start now and see how much i can report about the last months +since we had been celebrating our 1st birthday in May. A lot has happened +since then, matroska is on a very good way to become a well respected and +supported format. But here the news one by one :

The most amazing thing to happen was probably that we can now play MKV +files on PocketPC's with Betaplayer. +This great player is also a Corecodec project, like PocketMVP. Picard, its +main developer, was using Haali's integer C library to implement matroska +support in it, and there is more to come.
Talking about Haali's library, he released the alpha version of his DirectShow +splitter filter already, you can get it here. +Most of the bugs should be resolved already, and this new splitter will +be the basis for all future developments we are working on now ... but of +course, i cant tell you about this now ;) ...
Kyle Katarn has released a new version of his VideoInspector +tool, that will tell you everything about your matroska, AVI, MPEG and MOV +files
Spyder was recently improving on his alpha tool to mux MPEG 1/2 video +into MKV files. It can be obtained from here, +and there is a thread about it on Doom9.
We are working on a complete rewrite of the tagging system, find the docs +proposals +here. At the same time we are working hard on implementing our menue +system, the proposal is here.
Goldenear was putting a lot of work into a tool to create matroska files +containing a complete CD, with chapters marking every song. There are several +options for the compression format to be used, but default is FLAC. The +tool is called MKAencoder and can be obtained from here. +Its a script for EAC, the great +Audio CD ripping tool. He also updated the matroska plugin for +Foobar2000, called foo_matroska, +to be loaded from here. A Guide on how to use it was posted on Hydrogenaudio.org

Thats it for the time being, more news soon :) .....

A new version of the Matroska Pack +(v1.0.3) was released today. This version supports new Matroska fonctionalities, +the TTA lossless codec and all other DirectShow filters have been updated.

Mkvtoolnix (v0.9.5) +was also released with the same new functionalities and many bugs fixed. +It depends on a new version of libmatroska +(v0.7.3) that is up to date with all the latest additions to the specs.

2004-08-08

We have distributed the 200,000th Matroska +Pack v1.0.2 this week-end.

2004-05-01

Its matroska's 1st birthday today !!! +Exactly one year ago, we were publishing the first public tools to create +and playback matroska files, at that time only for the Windows platform, +of course after more than one year of preparation and specs definition already. +
+As of today, our matroska playback packs are downloaded more than 40,000 +times each month, the format can be used and played back +on Linux, Windows, MacOSX and BeOS, and this is certainly not the end ..... +in fact we have big plans with matroska and gstreamer, so that we can make +a real, free and opensource multimedia platform, similar to Quicktime and +Video for Windows ( VfW ) or DirectShow.
+A big, big thank you goes out to the team and all our supporters and users, +as well as to all the developers who have been working actively on implementing +matroska support in their tools, thus supporting our contraints to establish +it as a free, modern and open alternative to good old AVI, and MOV. We hpe +that there may be many many more birthdays for our 'baby' and that it will +grow and become what its parents had in mind when designing it : a beautiful +and intelligent opensource and open standard multimedia project. Here some +more News about it :

the main libraries for matroska writing and reading, libmatroska and + libebml, are now released under the L-GPL + license rather than the GPL/QPL + dual licensing system we have been using so far. This means that we are + prepared to open up the format for developers wanting to implement matroska + support into commercial applications by offering them a more liberal license, + as we feel quite safe to do that after one full year of usage and testing.
matroska is on its way to go Stable Version 1.0 + soon, we just havent finally decided if we will wait for the actual implementation + of the matroska + menue system until 1.0, or if we will add that later, once + we will move towards 2.0.
Peter Pawlowski has extended his support for various audio compression + formats packed in the matroska container in his great audio player Foobar2000, + and added support for the very latest matroska tagging system. He also + added more decoders to work in combination with containers like matroska + and MP4, instead of their 'native' framing.
Frank Klemm, the developer of MPC, + has started to work on a version of it that can be muxed into matroska, + called SV 7.5, allowing the use of MPC for movies. After that, we hopefully + we will even see him working on a SV8 version, with support for multi-channel + ( 5.1 Dolby Surround ) and DRC ( dynamic range control ).
DVD, the author of DVDtoMKV, + the great all-in-one DVD compression program, has finished his exams ( + successfully, we have no doubts here, do we ) and promised to continue + working on it soon. The first alpha was very well accepted by the users, + and we are eagerly awaiting the next versions now. If you are interested + to test the existing version, you will find it here.
A guy called DarkDudae made a nice Windows GUI for mkvextract, in case + you really plan to extract the video and audio from your matroska files, + to convert them into DVDs or any other video format. Read more about it + on Doom9.
The new matroska playback packs for Windows, + version 1.0.2, were released to the public on + April 1st. We fixed a couple of minor bugs in some of the programs distributed + in them, and also changed the standard behaviour for the installation + of some of them, especially Morgan + Stream Switcher, as it was causing problems on the machines + of some users, especially those with overloaded 'codec packs' installed. + You can download them here.
As mentioned above already, we are currently in the process of porting + Gstreamer to + Windows, investigating if we can use it to convert matroska+gstreamer + into a real, free and opensource multimedia alternative to Quicktime ( + with MOV ) and VfW ( with AVI ). We also have plans for a free movie editor + based on this platform, and the possibility to export into MP4, AVI, MPEG + and of course matroska from it.
There is still no stable release of Xine + with matroska support, but it was reported to me that the CVS version + is working quite nicely already. If you're on Linux, its a must for you + to test it :-) ! If you dont like to be 'guinea-pig' for CVS, the latest + pre-release ( + RC4 ) is for you, it even has seeking support already. Of course, + VLC and mplayer + will work fine also, only the current Gstreamer plugin for matroska seems + to have some problems still, being looked at.
The programmer of Zoomplayer, + our friend and long time supporter |Blight| has improved + matroska support in his latest version of his great Mediaplayer. It can + now read Aspect Ratio ( AR ) information from the matroska track header, + independant form the decoder filter that was used, and it will also read + the track name and display it. If he goes on improving his matroska support + at this speed, our two favourite players MPC + and TCMP really will + have to watch out to not get left behind ;-) .... but we heard TCMP5 is + in the works already ....
+
+ Ok, thats it for today ... more news in a couple of weeks, you all know + i have been quite lazy about that recently, and i dont think this will + change soon ;-) ..... and dont forget to have a toast on matroska's 1st + b-day later during the day !
+

2004-01-20 +
+Some more great news for the new year !!

foobar 2000, the great audio player and winamp alternative has native + Matroska support now for .MKA files, thanks to a plugin + from Jory 'Jcsston' Stone. Get the 'special installer' from here + and activate matroska support in the installer setup.
We have MPEG2 and MPEG1 video in MKV working !! More about this soon + ...

2003-12-03

This is the first news entry i am writing since august, what a +shame !! Some people even contacted us if matroska is dead because +of that, which of course is ridiculous, as matroska has moved forward a +lot during the last 3 months. It were mainly private reasons that didnt +allow me to update this page as often as i should have, please accept my +apologies for that !
+Now, to give you a brief overview of what has happened since august, read +here :

We have added a new lacing system to libmatroska, reducing overhead + for some audio formats significantly, by introducing a so-called 'EBML + lacing' in addition to the old, well-known 'Xiph lacing', + inspired by Ogg Vorbis. The main library will now by default mux any audio + track in 'auto' mode, choosing the best lacing mode automatically for + every audio track, and thus ensuring minimum overhead. Its not astonishing + that a Vorbis track muxed into a .MKA file, in 9 of 10 cases, will now + result in a smaller file than the original Ogg ;-) ....
+ As a result of that, all existing demuxers and parser filters had to be + compiled against latest libmatroska, otherwise they couldnt play the new + files. Older files stay 100% spec compliant, as the new lacing is only + an extension to the specs, not a change.
mkvmerge from Mosu's great mkvtoolnix set of matroska muxing/editing + tools, is now capable of muxing DVD Style Subtitles, + generally known a VOBSUBs, into the matroska container, + and meanwhile most players do support playback of them fine. It was very + surprising to see, that the DVD subtitles are not so big at all, especially + when demuxed from their MPEG transport layer. Especially our Asian fans + are quite happy about this feature, as it will allow them to save the + OCR process, which reportedly isnt very big fun for Asian languages ;-) + ! Of course, the size of a vobsub track is still a couple of MB ( typically + 2 - 5 MB ) per language, so it will use a lot more space than a SRT or + SSA track. To reduce this a little bit, we also added compression via + zlib to the SPU packets in the subtitles, saving another 25 - 35% of the + subtitles track size. Playback on Windows via DirectShow, again, is ensured + thanks to Gabest's wonderful DVobSub subtitle filter ( vsfilter.dll )
both mkvmerge and VirtualdubMod have had the ability to write + track names into matroska files since some time now, to allow + custom descriptions of any audio or subtitles file, like 'english - Director's + comment' . Unfortunately there was no way to read and display them in + the players supporting matroska yet. This has changed now, because Toff + from the corecodec Team modified the matroskasplitter.ax parser filter + by adding a new powerful interface, and on top of DirectShow. Now it is + possible to read those 'track names' on DirectShow, and meanwhile there + are already 4 players supporting it, namely 'The + Core Media Player RC5' , 'Zoomplayer' + , 'BSplayer' and 'KoolPlaya' + . Zoomplayer can now even support automatic aspect ratio compensation + via this interface, and completely independant from ffdshow and its resizing + capabilities. The Videolan team is implementing + support for track names into VLC right now, so even on Linux this should + be available soon.
AAC and SBR AAC tracks can now be + muxed from MP4 files also, again in mkvmerge. That way + the SBR ( Spectral Band Replication ) nature of the AAC track is also + automatically detected, other than when its muxed from the AAC container.
we put up a new Samples Page, + where we are offering state-of-the art sample files, so that new users + can download them and get an impression what can be done with the powerful + matroska container. The very latest of them is the Matrix + Reloaded Trailer, and these will be available in 2 version, with XviD + 1.0 Beta and RealVideo9, and both contain track names, chapters, and even + attachements.
while matroska can support Variable Frame Rate ( VFR ) by nature, there + are currently no video encoders available that would support this feature + by default. We found a little workaround, as latest mkvmerge will allow + to use an external Timestamp File to create those files, even if they + were compressed on CFR tools. For more information, read the New + A/V container section on Doom9.org + .
we always received a lot of criticism, especially from the Linux world, + why our main library is written in C++, instead of just C ! Our developers + are still backing up this decision, as they are convinced that the object + orientated C++ language will be better for a container format. However, + we were aiming since some time to get support for matroska in the great + FFMPEG open + source video library, but to no avail, as their main developers were postulating + a C library for integration of matroska into their libavformat + collection of container demuxers. It was again our friend Ronald 'BBB' + Bultje from the Gstreamer development + team, who was closing the gap, by completely rewriting the matroska libraries + libmatroska and libebml in plain C ! His library is already in the Gstreamer + CVS, and was used for his matroska gst-plugin. We hope to be able + to make a patch for libavformat soon, to get even better support for matroska + than is existing already.
Last but not Least : There has been a lot of rumour about that, but + yes, its true : We are in contact with at least one company making hardware + DVD/MPEG4 players, about implementing matroska support into their + units :-) !! We cant tell you right now who they are, but this is not + a fake, and it may happen sooner than you all can believe ;-) .....

We were pretty lucky when i decided to send this email, my guess. Only + by chance i was informed that VLC, + the great opensource player and streaming server project from France ( + now with native matroska support ), would be included in one of the upcoming + issues of CHIP, one of the biggest ( if not THE biggest ) PC magazines + in Germany. I just contacted the member of the CHIP team about including + matroska tools in the same issue, and he promised to look at it. After + a short while we were informed that a short article about matroska is + already on its way, and they would be pleased to include our tools in + the September issue of the magazine. However, they need the working software + for testing until 4th august, and this was a fine opportunity to set a + release date for the complete development team, and we wanted to have + chapter support by then in best case. Now this seems to be working out + great, most of our software is ready and already half way tested, and + it seems that CHIP will really invest some time into presenting our tools + in a very positive way. Chapter support was the last remaining feature + where OGM, a kind of 'competing' opensource container format to matroska, + had a small advantage, so we are quite eager now to release what we have + done now, and we will do so on 4th august officially, same date when we + have to give the software to the CHIP guys for getting it onto the CD + coming with the September issue. Stay tuned and watch our features + list turning green, there is even more to come ;-).

2003-07-28

We are back !!! Our team was going through a hard time + during the last 4 weeks, but hopefully we have normality back now. What + has happened ? Well, the central server of Corecodec.org, the opensource + community we chose to be hosted on and where our CVS is on, was hacked + from somebody who obviously wanted to hurt the project. You may ask why + i can be so sure about this, well there are attacks and attacks, and this + attack was simply ment to destroy the server, or in best case make sure + that corecodec.org as a service will be down for a certain time, it was + no attack to get control of the server to be able to make illegal things + from it, or to make other fancy bullshiting from it.
+ Everybody who was ever participating in an opensource project as an active + developer can imagine how bad it was to have lost CVS, but to make sure + this may never happen again we have installed some hidden CVS servers + now, so in case corecodec.org gets hacked again ( and this is what we + seriously expect to happen ) we can quickly switch to these private machines, + and development of the container can go on by all means. Whoever is trying + to prevent matroska from becoming widely adopted and used, and for whatever + reason this is done, we will make sure he will fail. Every server can + get hacked if somebody is just trying hard enough, no doubt. There is + no need to prove to the world that corecodec.org can be hacked, we are + not even claiming that its a pretty secured server, so the only conclusion + we can make out of the repeated attacks ( this was not the first time, + believe me ) is that matroska and corecodec are unwanted by certain people + in the video and audio encoding world. You call me paranoid ? All servers + get hacked occasionally ? Well yes, maybe i am really starting to become + paranoid, but i can smell stuff if there is some, belive me.
+ However, to show that all these attempts can not stop something thats + REALLY good, please allow me to list the events of the last 4 weeks :
Thanks to our core dev team member Jory 'jcsston' Stone, who made it + all rolling with a Real reader and a separate matroska writer plugin ( + to be released soon ), we can now mux RealVideo 9 into matroska files, + as well as most RealAudio codecs, and there are even three different ways + to do it. Muxing Real video/audio into matroska is one thing, but playback + on Windows, especially via DirectShow was a completely different story. + It was again Gabest, the author of the best matroska DirectShow parser + filter and the DirectShow muxer filter, who solved the problem by creating + a wrapper filter for the Real DLLs, which can be found on every Windows + PC once the RealOne player was installed. As all his other recent stuff, + these wrapper filters can be found on his Guliverkli + page. In the package there is also a Realmedia splitter filter, so + that now all Real files can be played on every normal DirectShow based + Mediaplayer, but this filter can also be used to mux Real content into + the matroska container, if a suitable DirectShow graph is built in Graphedit, + with Realsplitter opening the Realmedia files and matroska muxer filter + connected to it. To make things easier for normal users who are not capable + of building DirectShow graphs in Graphedit, there is a tool existing from + 'Dark-Cracker', a well known developer and forum member of Doom9, who + made an easy to handle GUI + for that.
+ Of course, muxing RealMedia into matroska will also work fine on Linux, + Mosu implemented this into the well known MKVtoolnix + compilation, and the latest version with Realmedia handling should + be released soon. His last mplayer patch ( it is now in official mplayer + CVS already ) can also play it fine, so the support for RV9 and RA in + matroska is almost perfect on Linux already, and should soon be possible + on BeOS and MaxOSX also, using the very same tools.
A big release can be expected from us soon, and this time we have set + a date until we will make this release, and for a very good reason. By + chance we got in contact with CHIP, one of the biggest ( if not THE biggest + ) PC magazines in good old Germany. The CHIP guys promised to look at + our tools for matroska file creation, and to include them into the SEPTEMBER + issue of the magazine, if found good and working correctly. We dont have + any doubts that our stuff is working, and with some luck we may even be + able to add chapter support to most of the tools, mainly VirtualdubMod, + both of the DirectShow parser filters and mplayer. To learn more about + the planned features of matroska, and when we think we will be able to + add them, can be found here.
Another important thing was being prepared in the last 4 weeks, and + we expect it to be one of the most important milestones for the complete + project. Most of the matroska files that are currently created by the + various existing tools, are so-called 'VFW/AVI compatibility' files, simply + because of the reason because they are made from either AVIs or OGM files, + or created with tools that are VFW based, like VirtualdubMod. In this + mode the matroska container is more or less clueless about the content + it has, as all the tools do is to set the matroska codec IDs to V_MS/VFW/FOURCC + for video and A_MS/ACM for audio, and all the important codec data are + simply copied from the corresponding VFW structures ( BITMAPINFOHEADER, + VIDEOINFOHEADER and WAVEFORMATEX ) in the KaxCodecPrivateDate filed in + the matroska track header. This mode was always planned and is also very + necessary to be able to support EVERY existing AVI file, whatever codecs + it may use, but we were also always convinced that we should try to enforce + that matroska files are used in their very own 'native' modes, also to + express the cross-platform idea behind the project.
+ Thanks to the work of David 'DaveEL' Leatherdale, author of the well known + tool avs2avi and moderator on Doom9, we are a very big step closer to + this goal. Dave, after adding MKV output to avs2avi, made a new tool called + avs2matroska, and this tool is NOT using VCM codecs for file creation, + but can use existing DLLs from certina codecs for file creation, and those + files will be native files ! For a first test avs2matroska is statically + linked to the opensource, education MPEG4 encoder project XviD, + and first alpha versions are now being tested thoroughly by a limited + team of alpha testers, but the created files work fine already. We hope + to be able to release avs2matroska out into the wild on 4th august also, + but certainly only to a limited audience of users who will be capable + to compile their own binaries from the XviD sources, and only for test + purposes. These native files should play perfectly in mplayer + and VLC by then, and also on Windows + DirectShow with ANY installed MPEG4 capable DirectShow + decoder filter, such as DivX5, 3ivX, NeroDigital and of course the great + ffdshow decoder + filter, thanks to a small translator filter ( also made by DaveEL ) called + 'timestamp manager'.
+
+ I hope this is enough news for today, now that we have our CVS back we + promise to keep you up-to-date about the development of the project more + frequently :) !

The latest matroska download + pack for Windows users is now available from our downloads + page. It was made by Brendan 'The Edge' from Ireland and does detect automatically + what version of Windows is used, installing the correct DirectShow parser + filter and subtitles filter ( Gabest' DVobSub ).

Yes, its true !!! The Videolan guys have added experimental matroska + support to the latest version of their nifty player, VLC 0.6.0. More on + Videolan !
+ To make it even better, Sam, one of the leading developers of Videolan + suggested to include libmatroska into the official Debian release, which + would make the matroska container format a widely supported thing at least + in the Linux world. This would fit very well into the picture that at + the last GUADEC meeting in Ireland + the GNOME people from the Gstreamer + team discussed the possibility to make matroska the default output + format from gst-rec, the main capturing application from Gstreamer. Big + thanks to Ronald 'BBB' Bultje here, who has been the main speaker for + matroska in this respect.
Mosu has released mkvtoolnix + 0.5.0 on his site + . Major changes include the adding of SSA/ASS muxing, changing the win32 + compile from cygwin to mingw, + and the fact that in this release reference priority elements are supported + now ( important for native MKV video streams with b-frames ).
The fansubber team from Anime-Xtreme.com + have released their first anime + movie using the matroska container. To get it you will need bittorrent. + This is the first real movie release using matroska as container i am + aware of, and this will definitely be the last kind of announcement for + these from my side from now on, this is just to let you know that our + hard work found its friends finally ;-) ... i am convinced this will NOT + be the last release in .mkv container format ...
DaveEL is making it true. Expect a release of avs2matroska in not so + far future, with xvid.dll dynamically linked and writing native matroska + MPEG4 files.

Gabest has made it possible : his last version of the DVobSub + DirectShow filter ( 2.26 ) has a source filter coming with it, so + that you can now mux SSA subtitles into matroska files with + his latest matroska + muxer DirectShow filter ! For playback of these files you need DVobSub + 2.26 again, and his latest matroska + DirectShow splitter/parser filter. Please check the Gulliverkli download + pages for newer versions in any case before downloading. As a sidenote, + his muxer filter will also allow transmuxing of Microsoft WMV9 video files + ( ASF/WMV container ) fine into matroska files, from Graphedit, and with + WMV9 VCM installed on your PC you can even open and edit + the files in latest VirtualdubMod + :-) ....
+ Mosu has released + a new version of his mkvtoolnix + for Linux also, tagged 0.4.4 as the latest libraries are. This new version + includes file splitting capabilities, and he has changed the CLI commands + almost completely. There are 2 different win32 binaries now, first Mosu's + cygwin + compile and then a new VC6++ + compile made by Nic, which doesnt require cygwin.
