Re: [osg-users] ReadImage not routing to plugin?

Hi Robert, There isn't any easy way around this as there isn't a 1:1 mapping between all file extensions and loaders can load files. The extensions that a 3rd party library like ffmpeg supports isn't even fixed w.r.t what version of the OSG is compiled against it. For instance we might make an

Re: [osg-users] ReadImage not routing to plugin?

OK, I see the design flaw I was missing. You have to load a plugin library in order to see what extensions it handles, and plugins are only loaded when needed. But "needed" can only be known if you have loaded the plugin already. That's why there are so many hard coded extensions in the

Re: [osg-users] ReadImage not routing to plugin?

HI Rob, The OSG uses a chain of responsibility pattern for the plugins and will first attempt to load file by calling all of the currently loaded plugins first, then if it fails then look for the plugin named the same as the file extension, in your case .ogr. There are also some built in aliases

[osg-users] ReadImage not routing to plugin?

I am trying to understand why osgDB::readImageFile( "abc.ogv" ) does not get routed to the ffmpeg plugin. I get no image loaded and I see that the readImage method of the plugin is not even called. If I call osgDB::readImageFile( "abc.ogv.ffmpeg" ) it works, but that is not going to be an
