Problems with Snapshot 202502

Submitted by Kuro on

I just downloaded the latest Snapshot 202502 from Github.

Nice that it has added 14-bit support for Olympus cameras.

However, I'm seeing 2 big issues:

1. Extremely slow decoding speed. Decoding a compress Fuji RAF file is now at least 10x slower.
2. Yellow tint on every decoded image (RAF, CR3, ORF, etc.) Almost seems like WB and tint are off.

Any suggestions on what the problem might be?

Thank you for your feedback.
1) Downloaded latest master (commit ID: ad067c510bacea51755711c1b624da78b1812fba) and commit just before 202503 snapshot (commit ID: 29d9785c2d5f71db7c6ae2834003cd211bd6a421)
2) Compiled both as make CC=clang CXX=clang -f Makefile.dist on my home FreeBSD router (14.2)
3) Checked with Fuji GFX100 test files from rawdb.dnglab.org: four compressed files and two uncompressed via

time ./bin/uncompressed_raw /path/to/*.RAF

(to check decode time only)

Results
202403 snapshot (+all patches):

real    0m49,581s
user    0m47,898s
sys     0m1,284s

202503 snapshot + two newer changes (PhaseOne checks + CVE numbers):

real    0m44,326s
user    0m42,512s
sys     0m1,468s

The new one looks slightly faster (that could be test variation).

So, please check you're using same compile/etc/ mode for both versions (e.g. same OpenMP support: Fuji decoder is OpenMP-capable).

Regarding your 2nd complain:
It is useless to discuss colors/tint/etc without reference to specific RAW file/processing options used.
The result I see from same files set via dcraw_emu -w -T looks absolutely normal: https://www.dropbox.com/scl/fi/46fz50mtg77ddzytccbpa/Fujifilm-GFX100S-14...

I found the problem. I forgot

I found the problem. I forgot to update the libraw header files for my project and it was using the old data structures, causing heap overflow and all sorts of weird problems.

It is all good now.

By the way, I only see 202502 snapshot on Github. Where is 202503? Is the master branch 202503? I downloaded the one from the master branch.

Thanks.
