Synchronization error near the end of file

Hi all,

I'm tring to get started with "libmad" so I've tried to make an
application very similar to "minimad.c" , the one included in the
source code, only that instead of reading and writing from STDIN to
STDOUT it reads and writes from and to files.

The problem that I get is that I get a strange synchronization error
near the end of the file :

 Decoding /balthasar/****.mp3
0  <-- ID3Tad size
decoding error 0x0101 (lost synchronization) at byte offset 3072836


The actual size of the file is : 3072949

I get this almost with every file I try to decode.

I manage the input by creating with "malloc()" a memory area of
"unsigned chars" of the size of the file , then I fread the mp3 file
into memory and pass the pointer to the callback input function .

I miss something or I made any mistakes?

Thanks for your help.


Bye

Marcello

PS= Do you know how to check the correctness of a Raw 16bit PCM
stream?? I've tried to play my file with many players , but it doesn't
work. Sorry but I'm a newbie of digital audio :)
