Attendance:

Discussion:

• Kimball: I hate supporting subsampled images.

• All three open fuzz issues say they’re from the core fuzz checker. They’re all the same thing.

• Peter: could make a more pedantic check flag, “don’t read questionable files.”

• Kimball: expose a bunch of new functions that have been private.

•  

  • Manage attribute lists

  • Then the next commit will be to switch Header.

  • I’ll break up the commits so we don’t have 4 Tb of changes to go through.

• Open Source Days

•  

  • Exr has 30 minutes on the second day, Tuesday.

  • Kimball: we’ve been  trying to convince David that these should be more like a BOF. Present for 5 minutes.

  • Topics:

  •  

    • Kimball: What I’d really like to hear is, do we want to grow the file format. Bfloat? Alternate compression schemes? 

    • Kimball: Do we want to reclaim control over pyexr, now used in deep learning applications for using floating point data. Used by Tensorflow graphics addon package The maintainer started referring people to another repo, but it’s moribund as well.

    • Imath changes

    • ABI stability

• V3.2 release

•  

  • Probably not by SIGGRAPH, but by September, for VFX ref plat.

  • Would be nice to have code in a branch, for people to see and test 

• NickP: OpenTimelineIO Disney Tech Talk

•  

  • Derive and algebra and calculus for time sequences, with sampling theory that allows the high math into code you can actually use.

  • Pythagorean holonomics: cubic curves whose derivatives and integrals are also cubic, so everything stays cubic all the way through.

  • Kimball: We’re going to be reworking our camera pipeline, could use a new time framework.
