How to properly compress FMOD vorbis audio

[fabrieunko]

Hello, I try your tutorial but I have this message on all the files I test. Is this normal?

extract.py VO_FR.FSB -o VO_FR
Traceback (most recent call last):
  File "F:\fmod\extract.py", line 131, in <module>
    main()
  File "F:\fmod\extract.py", line 127, in main
    exit(app.run(sys.argv[1:]))
  File "F:\fmod\extract.py", line 120, in run
    with open(fname, 'rb') as f:
PermissionError: [Errno 13] Permission denied: 'VO_FR.FSB'

and if I directly indicate the name of the fsb file I have this message

f:\fmod>extract.py VO_FR.dat -o VO_FR
Traceback (most recent call last):
  File "F:\fmod\extract.py", line 131, in <module>

    yield sample_fakepath, sample.name, fsb.rebuild_sample(sample)
  File "F:\fmod\fsb5\__init__.py", line 211, in rebuild_sample
    from . import vorbis

    vorbis = load_lib('vorbis')
  File "F:\fmod\fsb5\utils.py", line 76, in load_lib
    raise LibraryNotFoundException("Could not load the library %r" % (names[0]))
fsb5.utils.LibraryNotFoundException: Could not load the library 'vorbis'

Put libogg.dll and libvorbis.dll from that archive in System32. That's how I fixed this.

Hello
I follow this guide but I've got some but I'm having trouble finalizing the project...

What I've done:
file.bank => extract FSB file with quickbms
PythonFSB5=>extract all .ogg file
bincat to concatenate all .ogg file

now i do not understand that :
if I use oggvorb2fsb on this file I have a very small gain durring compression almost nothing
If i use oggre I have a very high gain , but crc error when I unpack file...

for now if I do this
file.bank => extract FSB file with quickbms
PythonFSB5=> extract all .ogg files
bincat => one big file
oggvorb2fsb5 => one big encoded file
hdiffpatch between original.bank and my new file
compress encoded file + diff file

during unpack
hpatchz encoded + diff file => restore my original file.bank

It works but very small ratio gain in conversion...

thanks for your help

regards

Use another hdiff patch from the decoded data from oggre_dec.exe to the concatenated ogg files. That hdiff patch should be tiny. Don't use oggre under freearc if you get a CRC fail.
