[vlc-devel] [PATCH 3/3] win32: window: re-create the window if it was destroyed externally

[Thomas Guillem]

This fixes dysfunctional vout when the user destroyed manually the window and
started a new video. The enable() callback need to check if the current window
is valid and re-create it if not.
