Subject: [Matroska-devel] Access to the Java source code
Message-ID: <481A287D.2070408@datacrow.net>

Hi,

I am running a fairly successful open source Java project called Data 
Crow (http://www.datacrow.net or http://sourceforge.net/projects/datacrow).
Data Crow is an all rounder when it comes to cataloging media. It 
allows, amog other things, to parse file information.
For the movie and music module I would like to add the ability to parse 
mkv file information.

It would like access to your svn repository 
(http://svn.matroska.org/svn/matroska/trunk/) for the Java source code.
Is this possible?

Cheers,
Robert Jan van der Waals

Subject: [Matroska-devel] Problem (and possible solution) compiling
	libmatroskadll in Visual Studio 2005
Message-ID: <465a4ad00805070922w3a1746b1gf1f6cee2ffbfa1c@mail.gmail.com>

Hi guys, I'm a new member here.

I recently downloaded libmatroska-0.8.1 and libebml-0.7.8, and I'm having
trouble getting the libmatroskadll project to compile in Visual Studio
2005.  libeml, libemldll, and libmatroska all compile OK, but when I try to
compile libmatroskadll, I get hundreds of errors.  Here are the first few
that come up, including the warnings immediately before them:

Lines 82 and 83 of kaxcontexts.h are:

extern const EbmlSemanticContext & MATROSKA_DLL_API GetKaxGlobal_Context();
extern const EbmlSemanticContext & MATROSKA_DLL_API
GetKaxTagsGlobal_Context();

I noticed that if I change the lines as follows, the code compiles and links
perfectly:

extern const EbmlSemanticContext MATROSKA_DLL_API & GetKaxGlobal_Context();
extern const EbmlSemanticContext MATROSKA_DLL_API &
GetKaxTagsGlobal_Context();

Is this a known issue?  Does VS2005 just interpret the address operator
differently than previous versions?  I haven't tried compiling the original
code in 2003 or VC6 yet.

Thanks

Subject: [Matroska-devel] Aspect Ratio in Haali Video Renderer
Message-ID: <3101.67.175.41.186.1210172243.squirrel@listserver.jriver.com>

Hi,

I am trying to use Haali Video Renderer in my application, but encountered
a difficulty. The filter works great except that it always tries to
maintain aspect ratio of the video. This makes it impossible to apply
custom aspect ratio.

Is there a way, by means of a COM interface for example, to tell the
renderer not to maintain aspect ratio - like the following Microsoft's
interface methods do:

IVMRAspectRatioControl::SetAspectRatioMode(),
IVMRAspectRatioControl9::SetAspectRatioMode(),
IMixerPinConfig::SetAspectRatioMode()?

Thank you for your help.

Yaobing

Subject: [Matroska-devel] How can I concatenate / append / combine segments
	of Matroska files programatically?
Message-ID: <465a4ad00805121014k3fa79d94wfb2a0d14a85dd34d@mail.gmail.com>

Hi guys,

I'm trying to write a class that will concatenate parts of two Matroska
files together.  I've seen examples of this in the mkvmerge program in the
mkvtoolnix toolkit.  However, that tool only appends complete files.  I'd
like to just append over *parts* of a source file onto the end of a
destination file.

Can anyone recommend the basic ways to do this?  The sample applications
included with the library illustrate muxing and reading/writing header data,
but it's not clear how to interact with the clusters and move them around
and still end up with an intelligible file.

As a side note, I haven't had much luck parsing any of the mkv files from
the matroska site with the test8 sample application--it seems like it just
loops through the files, finds no useful elements, and exits.  So that's
made it a bit difficult to examine the structure of a known good file.

Thanks!
--Peter

Hi,

 

When I use append feature to merge files, I got a "audio sync" issue.

I did some research with google and found the same question in your mailing
list archives.

But I cannot find any solution.

I need help.
