Hi Koduri,
You can create a Quad and then add the image stream, something like that:
osg::ref_ptr<osg::Image> image = osgDB::readImageFile(
"/sdcard/videodemo256256.avi.ffmpeg" );
osg::ImageStream* imageStream = dynamic_cast<osg::ImageStream*>(
image.get() );
if ( imageStream )
{
imageStream->play();
}
osg::ref_ptr<osg::Texture2D> texture = new osg::Texture2D;
texture->setImage( image.get() );
osg::ref_ptr<osg::Geometry> quad = osg::createTexturedQuadGeometry(
osg::Vec3(), osg::Vec3(1.0f, 0.0f, 0.0f), osg::Vec3(0.0f, 0.0f,
1.0f),0,1,1,0 );
quad->getOrCreateStateSet()->setTextureAttributeAndModes( 0,
texture.get() );
osg::ref_ptr<osg::Geode> geode = new osg::Geode;
geode->addDrawable( quad.get() );
Cheers.
