Move audio packets reordering from codec interface to demuxers for real
files (old and new format), pass only real extradata to the codec Enable cook codec from lavc, prefer lavc codecs for 14_4 and 28_8 formats. Disable internal 28_8, it's broken now and will be removed soon git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@17150 b3059339-0415-0410-9bf9-f77b7e298cf2
