[osg-users] ffmpeg-plugin does not recognize .ogv extension

Hi! I think I found a little issue with ffmepg plugin. According the source files Xine plugin supports .ogv extension (only) and ffmpeg plugin supports .ogg (only). It seems that .ogv is now official extension for video.: http://wiki.xiph.org/index.php/MIME_Types_and_File_Extensions
