Hello dudes,

I had given up by the first one who answered, but I will go through this since two of you were interested about this... I actually don't care about the filesize, I just wanted to know what exactly causes this. (for the record, wavpack always produces the same filesize in win and lin).

Here you go:

djzn at orion:~$ flac --version
flac 1.2.1

djzn at orion:~$ wine $HOME/win32/flac/flac.exe --version
fixme:ntdll:find_reg_tz_info Can't find matching timezone information in the registry for bias 180, std (d/m/y): 21/02/2010, dlt (d/m/y): 17/10/2010
flac 1.2.1
djzn at orion:~$

This fixme from WINE does not affect flac encoding at all, since the flac.exe in a windows native installation produces the very same flac filesize.

I believe that this could be a Windows API call that results in filesize mismatch compared to the Linux ELF executable, using the SAME COMPRESSION LEVELS or OPTIONS. Pointing out again that the executable from flac.exe in WINE is the exact same file in native windows installation. Tomorrow I will upload the two files.

Example from the console, without inserting tags or anything:

djzn at orion:~/music$ ls -l *
total 3,4M
drwxr-xr-x  3 djzn djzn 4,0K 2010-02-10 22:04 ./
drwxr-xr-x 85 djzn djzn 4,0K 2010-02-10 21:33 ../
-rw-r--r--  1 djzn djzn 3,4M 2010-02-10 22:04 situation_us_mix.wav

djzn at orion:~/music$ flac -5 *.wav
