Hi hybr! That's working!!! Finally! :D I installed the ffmpeg plugin and loaded the movie with .mov.ffmpeg extension. As you said before, the code is correct... only a plugin problem. Only the audio is not playing... but that's no much important. Thanks again! ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=36783#36783 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
