Is it possible to use osg::ShadowMap to generate the
osgShadow_shadowTexture texture, then use that texture in a subsequent
RTT pass as input?

Hi,
Thanks for the tips. I know the planes' orientations need to be right. I
assumed that by creating the Polytope from a BoundingBox that they would be,
and when I inspect the values I think they're correct. I did try flipping them
all in case I was wrong about the orientation, but that didn't
HI Petr,
Pulling in ffmpeg's head will almost certainly expose you to changes in the
API that we haven't caught up with yet. Try pulling ffmpeg from 13.04's
repositories.

Ok, so situation:
- running on Ubuntu 13.04
- downloaded latest OpenSceneGraph-3.2.1-rc2
- downloaded http://git.libav.org/?p=libav.git;a=snapshot;h=HEAD;sf=tgz which
should be latest libav I suppose
Then I tried to recompile OpenSceneGraph Plugins with this errors:

HI Chris,
It really is hard to know what is going on with your usage as I don't know
you data or the code that you are using with the OSG.
It could be a problem with the orientation of the planes of the Polytope -
they are need to be consistent with all their normals pointing inwards. If
you hav
Hi Chris,
I also fight a long time with PolytopeIntersector and PagedLOD. Did you add
callback to read your PagedLOD? See osgSim::LineOfSight for an example.
Does it help?

Which version of ffmpeg were you trying to compile against? ffmpeg keeps
changing it's API, we do try to keep up but it's a moving goal post.
The ffmpeg version I'm compiling against i
I downloaded latest libav, make, make instal etc..
Then I just re-run building osgPlugins and ffmpeg started building and crashed
with some errors

Hi Petr,
sorry I can't help you with this. I use CMake to generate the projects
and usually compile under Windows only.

Hi Petr,
What is your OpenSceneGraph version?
Did you build it from scratch and compile it with ffmpeg?
For me it seems you have some mixed install here.
using export OSG_NOTIFY_LEVEL=DEBUG I found

isn't readable)

Hi Petr,
Do you have ffmpeg plugin built and installed?
Here is small snippet from my application:
std::string libName =
osgDB::Registry::instance()->createLibraryNameForExtension("ffmpeg");
osgDB::Registry::instance()->loadLibrary(libName);
osg::Image* image = osgDB::readImageFile("d:/tmp/
Hi,
I have a problem which Im not able to solve.
Im using this piece of code in my application:
Code:
osg::ref_ptr video1 = osgDB::readImageFile(
"external/videos/a.mp4.ffmpeg" );
which always returns NULL pointer. The path is right, I even tried absolute
path, I tried move that mp4 video to
Hi Lv,
can you provide a full compiling example? Then I can test it with the
Intel Compiler tools. Unfortunately they are not free but I have a
license in the company.
I agree with Robert, that the memory management with ref_ptrs is
rock-stable if used correctly, so a full example could help t

I haven't actually used Windows for about 13 years, and even then it was
only for a short spell experimenting with a home pc before I installed
Linux on it... So
