 The samples {{{globo\ hd\ 20120424\ champions\ league\ paulonline.ts}}}
 and {{{VasHD.mpg}}} in http://samples.ffmpeg.org/ffmpeg-
 bugs/trac/ticket4544/ show many warnings on decoding -
 {{{ac->oc[1].m4ac.chan_config}}} is reset in aac_decode_frame_int() after
 output_configure() did not return an error.
