[Flac] libflac doesn't find more than one metadata block

[Hadrien Lacour]

Hello, I'm currently doing a little music player using libflac and libao. What
I've currently done works as it should, but I have a problem where only one
metadata block is detected, even if there are more.

This is using flac 1.3.2 on Gentoo amd64.

The main code file is attached, it mainly follows the examples given with the
libflac and libao doc. And here's what metaflac --list gives me on a test file:

METADATA block #0
type: 0 (STREAMINFO)
is last: false
length: 34

METADATA block #2

If anyone has the solution or some clues, I'd be glad.
