Hi Al,
Which view is hero in your input, and which branch did you build from?
The iif-optimisations branch doesn't fully support right-view-is-hero
multiview EXRs. I think it would push black into the left view. The
iif-weta branch supports both left and right view as hero. It is a
redesign of iif-optimisations which keeps the ABI closer to 1.7.1
The develop branch also has optimisation as part of the EXR-2.0
codebase, which should work for both left and right hero multiview files.
If symptoms persist there is a commented out line in
ImfScanLineInputFile.cpp which disables the optimised path. That might
help debug the problem:
// TODO-pk this disables optimization
// _data->optimizationMode._destination._format =
Imf::OptimizationMode::PIXELFORMAT_OTHER;

Hi Al,
I had a look and I can't seem to find any issues, which worries me as you may
be bumping into something not quite seen yet.
Could you give me an idea as to what you were doing to prompt the failure? Are
you reading existing imagery with a tool linked against v2.0?
Or are you writing out stereo images with v2 code base?
Either way, what is exrheader giving you?
Piotr

Hi all,
Just built the iff-optimised version, I tweaked the code in IlmImfTest
to spit out some timings between the aligned and unaligned tests.
The timings are almost identical, which isn't what I'd expect, is there
anything I should be doing here to make this work, I also tried using
the optimised libraries in our playback tool and that showed little to
no speed improvements.
I'm guessing I'm not using these correctly, is there some compiler
option I require or memory alignment needed?
cheers

I've noticed than stereo images don't seem to be working, it's missing
the left channel (it's black).
OpenExr 1.7.1 works as expected though, has something changed with this?
Anyone else noticed this issue ?
