    aacdec: Lower the number of frames required to detect ADTS
    
    For live audio streams, requiring 500 frames for a stream to
    be detected is a bit overkill.
    
    This allows live ADTS streams that don't start nicely at
    a frame boundary to start up more quickly, e.g.
    http://mp3.streampower.be/radio1.aac.
