    Implement auto_calc_flac() -- calculate granulepos for flac packets (if · 49825f9c
    conrad authored
    granulepos is not given in Ogg framing). This tracks the current granulepos
    and determines the block size by reading the FLAC frame header. Note that
    this patch doesn't handle blocksize codes 0000, 0110 or 0111, which
    require poking elsewhere to get the actual value. Nevertheless this patch
    appears to handle the common case framing, and in any case it is very rare
    for Ogg FLAC packets to not have a granulepos.
      * Handles both old-style Ogg Flac framing ("Flac0") and current framing
      * Tested on all flac-in-ogg files from MPlayer samples:
      * Tested with valgrind --leakcheck=yes on src/examples/read-file (no leaks)
