/* Notes about seeking:

   The full seek table consists of:
      uint64_t sample (only 36 bits are used)
      uint64_t offset
      uint32_t blocksize

   We don't store the blocksize (of the target frame) and we also
   limit the sample and offset values to 32-bits - Rockbox doesn't support
   files bigger than 2GB on FAT32 filesystems.

   The reference FLAC encoder produces a seek table with points every
   10 seconds, but this can be overridden by the user when encoding a file.

   With the default settings, a typical 4 minute track will contain
   24 seek points.

   Taking the extreme case of a Rockbox supported file to be a 2GB (compressed)
   16-bit/44.1KHz mono stream with a likely uncompressed size of 4GB:
      Total duration is: 48694 seconds (about 810 minutes - 13.5 hours)
      Total number of seek points: 4869

   Therefore we limit the number of seek points to 5000.  This is a
   very extreme case, and requires 5000*8=40000 bytes of storage.

   If we come across a FLAC file with more than this number of seekpoints, we
   just use the first 5000.
