Hi,
I did a example to load video. But here it is playing correctly in the center
of the screen. Here I used camera manipulator as TrackballManipulator().
But in project (as given above) i am not using TrackballManipulator(). If I
used TrackballManipulator() then the 3D models are out of screen.
Can you please help me what settings i need to set to get the video correctly
on to the screen.
In the exaple program my transformation matrix is empty. That is I am not doing
any operatins on transformation matrix. If I do the same on my project then the
video is out of screen.
And in example program the video is repeated (looping) automatically. But in my
project it is not and giving error "no frames" when reaches to the end.
Can you please help me what to do
Here is my example program
Code:
void main()
{
osg::ref_ptr<osg::ImageStream> mImageStream;
//osg::ref_ptr<osg::Texture> mVideoTexture;
osg::ref_ptr<osg::Texture2D> mVideoTexture;
osg::ref_ptr<osg::Geode> mVideoGeode;
osg::ref_ptr<osg::Geode> geode = new osg::Geode;
osg::Image* img;
img = osgDB::readImageFile("C:\\Test\\ar352wa.mp4.ffmpeg");
mImageStream = dynamic_cast<osg::ImageStream*>(img);
mVideoTexture = new osg::Texture2D;
mVideoTexture->setImage( mImageStream.get() );
geode->addDrawable(osg::createTexturedQuadGeometry(
osg::Vec3(0, 0, 0),
osg::Vec3(videoWidth, 0, 0),
osg::Vec3(0, 0, videoHeight)
));
geode->getOrCreateStateSet()->setTextureAttributeAndModes(0,
mVideoTexture, osg::StateAttribute::ON );
osg::MatrixTransform * transformation = new osg::MatrixTransform();
transformation->addChild(geode.get());
mImageStream->play();
osgViewer::Viewer viewer;
viewer.setCameraManipulator(new osgGA::TrackballManipulator());
viewer.setUpViewInWindow (200, 200, 600, 600);
viewer.setSceneData( transformation );
while(!viewer.done())
{
viewer.frame();
}
}
...
Thank you!
Cheers,
Koduri
