[vlc-devel] [PATCH] GUI-Qt: update components/extended_panels.cpp

[Victorien Le Couviour--Tuffet]

Retrieve already loaded audio and video filters at window construction.
This fixes the bug occuring when enabling or disabling a filter from Qt:
it was rebuilding a filter chain adding or removing the concerned filter,
but as it didn't retrieved the ones that were already there (enabled through
command line), there were just thrown away.
