 The OGG demuxer fails to demux the AAC in sample file xx/xx.ogg

 no audio is produced using ffplay from
 4edcdf5c443b796dcd939d7d2a0cc08578726863

 the bug seems to sit in the ogg demuxer. reason for stating this is that
 i've tested with mplayer (1.0rc4-4.4.3 from ubuntu maverick)

 mplayer -demuxer ogg -ac faad -> sound
 mplayer -demuxer lavf -ac faad -> no sound

 note that

 mplayer -demuxer ogg -ac lavc -> no sound

 this for different reasons - aac uses unsupport features apparently.

 i know for a fact that this issue is at least 3 years old,
 http://trac.xbmc.org/ticket/5205 , so me using a mplayer with an older
 ffmpeg shouldn't influence the results.
