[osg-users] [osgPlugins] osgDB::readImageFile() chooses ffmpeg over libpng
OSG-3.3.7 both plugins osgdb_png and osgdb_ffmpeg loaded. osgDB::readImageFile(image.png) chooses ffmpeg over libpng to load .png image files. I checked ReaderWriterFFmpeg.cpp, and it does not add the .png extention. How do I give libpng priority on .png files. Thanks :) -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=63688#63688 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Forcing a scene to rebind textures
Hi Robert, As a matter of fact I have a GraphicsContext managed by osg. And it properly gets destroyed. I later create a new View and set on it the scene data that was previously set on the other view (which is now discarded). I then see the errors below and get crashes. Please note that this does not happen on simple scenes but on scenes containing osgearth maps. There is something I am not doing properly when destorying the 1s view which leaves the scene in a bad state. Question is to find what is wrong with the scene. robertosfield wrote: Hi Phillipe. When a graphics context is detroyed a releaseGLObjects() on the scene graph should be called. When a context is destroyed outwith the control of the core OSG then calling osg::discardAllGLObjects(contextID) should be done to make sure any cached GL objects handles and discarded for that context. The osgViewer library tries to do this all for you, but if you've implement your own context setup/destruction then it won't have all the control to do this automatically. Robert.
