flac dev - Feb 2010 - Contents of Flac-dev Digest, Vol 65, Issue 4

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

Another possibility could be different line endings in some
metadata file (ie '\r\n' on windows and '\n' on Linux).

It would be nice it the ones you post are a little smaller 
than these.

Cheers,
