* src/audio_output/input.c

  src/libvlc.h :
       First try to implement "user audio filters"
       You can provide a list of audio filters that you want to add to
       the pipeline (only the "headphone", at that time).
	(use --audio-filter filter1,filter2,...)

   ***Warning***
   It seems to work, but no guarantee at all. Perhaps all is bad
   and the commit should be reverted, as it could break audio output

* modules/codec/libmpeg2.c :
	Fixed a segfault when vout creation fails
