I just tried the  NyArtoolkit  library for processing, which involved GSVideo as well, however, when I tried to run the second sketch of this tutorial, I got the error that "error when detecting player, maybe some native resource is already disposed"

anyone encountered this before or has any idea how can I do with that? tried google but not much useful info..

thanks!

here is the tutorial of nyartoolkit:
