osg通过ffmpeg插件加载视频需要的全部DLL以及示例

osgDB::Registry::instance()->addFileExtensionAlias("avi", "ffmpeg"); osg::ref_ptr<osg::Image> image; //本地视频 image = osgDB::readImageFile( "D:\\video\\aaa.avi" ); osg::ImageStream* imageStream = dynamic_cast<osg::ImageStream*>( image.get() ); if ( imageStream ) imageStream->play(); //添加到四边形 osg::ref_ptr<osg::Texture2D> texture = new osg::Texture2D; texture->setImage( image.get() ); osg::ref_ptr<osg::Drawable> quad = osg::createTexturedQuadGeometry( osg::Vec3(), osg::Vec3(-1.0f, 0.0f, 0.0f), osg::Vec3(0.0f, 0.0f, 1.0f) ); quad->getOrCreateStateSet()->setTextureAttributeAndModes(0, texture.get() ); osg::ref_ptr<osg::Geode> geode = new osg::Geode; geode->addDrawable( quad.get() ); geode->getOrCreateStateSet()->setMode(GL_LIGHTING, osg::StateAttribute::OFF | osg::StateAttribute::OVERRIDE); osgViewer::Viewer viewer; viewer.setSceneData( geode.get() ); viewer.run();
