Re: [osg-users] pUserData crash when run .exe in debug or release version
Hi Nan, I don't believe its a bug in OSG itself, it's the stupid Microsoft debug libraries. I suspect you are linking against the third party libraries built for VS2005, hence its works ok in debug mode. It's certainly worth applying SP1 for VS2008, but you also must make sure you linking against the third party libraries built with the version of VS you are using. You could download the libs for vs2008 and use those and see if it builds/runs ok in debug mode? Let us know how it goes.

[osg-users] Compile problems against recent ffmpeg
Hi!
As reported on http://bugs.gentoo.org/347481 the osg 2.8.3 release (and
current trunk probably as well, as far as I can tell) has problems
compiling against recent ffmpeg snapshots. The critical commit there is
SVN revision 25652 from 2010-11-02, which is now in git:
http://git.ffmpeg.org/?p=ffmpeg.git;a=commitdiff;h=262d1c5d2206467809fd
By default it introduces a preprocessor macro called SampleFormat:
#define SampleFormat AVSampleFormat
As a consequence, all references to SampleFormat in osg will be
rewritten, even if they refer to some other C++ namespace. This leads to
errors like this:
error: ‘AVSampleFormat’ in class ‘osg::AudioStream’ does not name a type
Luckily the commit also provides a means to avoid the definition. Simply
include this line before including the av*.h from ffmpeg:
#define FF_API_OLD_SAMPLE_FMT 0
I'd suggest you include this line in FFmpegHeaders.hpp:
--- OpenSceneGraph-2.8.3.orig/src/osgPlugins/ffmpeg/FFmpegHeaders.hpp
+++ OpenSceneGraph-2.8.3/src/osgPlugins/ffmpeg/FFmpegHeaders.hpp

{
#define __STDC_CONSTANT_MACROS
+#define FF_API_OLD_SAMPLE_FMT 0
#include errno.h// for error codes defined in avformat.h

You can also download this patch from the Gentoo bug report:

[osg-users] Qt Library
Hi all, we adapted our software to the new Qt library, which is a good thing! Testing it on various systems leads us to some problems. The programs crash sometimes and we successfully catched the problem in the debuger. The crash happens when QPainter and osg paint to the screen simultaneously in two different threads. But! We can assure that the frame() method is called in the gui thread and setThreadingModel(osgViewer::Viewer::SingleThreaded); is called in the constructor of the widget. Does anybody have an explanation for that? Is osg creating its own painting thread even after setting it to SingleThreaded? Thanks for any hints. - Werner - ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Using osgShadows I can't see widgets
Hi Daniele,
When using shadow techniques, you have to put all your child that are
supposed to be shadowed in separate scene below the shadowed scene, as a
sibling to the rest of the scene.
E.G. if you have a hud:
root
|
||
HUD SHADOW
|
MODELS
This should fix your problem.
cheers
Sebastian
