The u member is an union meant to be used along with u.event_type if  
defined. There is no u.media_instance_reached_end so this field is not  
meant to be used with libvlc_MediaInstanceReachedEnd.

Of course that's not a bad idea though to initialize its value...

I would rather try to find why this is getting send two times... But  
this is a nice work around that work in some case!

The problem arise from the fact that the media_instance is listening  
to multiple variable to track input_state_change. I'll fix that ASAP.

Do you have a sample test app that show what is wrong? I could merge  
it into control/testapi.c. (I'll write one eventually).
