Hi Robert, right, the ffmpeg plugin is trying to load files without knowing if they are of a supported format. The related code is here: https://github.com/openscenegraph/OpenSceneGraph/blob/master/src/osgPlugins/ffmpeg/ReaderWriterFFmpeg.cpp#L149
The comment explains something related to videos served from internet. I'm wondering if it would be ok to move that code below, after having checked whether the filename contains a URL (performed a few lines below). This would stop the plugin to try loading every possible image and printing errors on the console.
