With the commentary as is it should be fine if you are using 0.9.0.  
However the code you sent is broken.

This shouldn't be commented.

But as far as you are using 0.8.6c you should simply use  
libvlc_playlist_get_input(), not libvlc_playlist_get_media_instance().

What do you mean the library loading failed?

Hope this helps,
