[Flac-dev] slow FLAC__file_decoder_seek_absolute()...

[Brendan Dowling]

I have a new idea for speeding up seeking.  Would it help if I were to
decode a few frames (and throw away the decoded data) before doing the 
FLAC__file_decoder_seek_absolute() call?  This would be so that the
decoder object could prime its min_framesize and max_framesize
variables.
