概 要GDIイメージに対してCD FLAC比較が動作しない。
詳 細CD FLAC compresion codec doesn't work for GDI images.
再現手順1. Take some Dreamcast image with a lot of CDDA tracks,
"Airforce Delta v1.000 (1999)(Konami)(NTSC)(US)[!][1S T-9501NAF]" for example.
2. convert it to chd
chdman.exe createcd -i "Airforce Delta v1.000 (1999)(Konami)(NTSC)(US)[!][1S T-9501NAF].gdi" -o "Airforce Delta v1.000 (1999)(Konami)(NTSC)(US)[!][1S T-9501NAF].chd"
3. check percentage of used compression codecs
chdman.exe info -v -i "Airforce Delta v1.000 (1999)(Konami)(NTSC)(US)[!][1S T-9501NAF].chd"
Hunks Percent Name
---------- ------- --------------
6,489 9.5% Copy from self
61,890 90.2% CD LZMA
268 0.4% CD Deflate
1 0.0% CD FLAC
追加情報Expected a lot of data hunks FLAC compressed, but it is not used, except 1 hunk.

I've also compressed this image with -c cdlz,cdzl switch (eg manually disabled FLAC) and got almost the same in size chd as previous -> its not the bug of "info" command, but something wrong during "createcd".

This only happens on GDI, for CUE/BIN with CDDA FLAC works fine.
