Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2020-08-02 20:06:44 UTC
media-gfx/blender is blocking cleanup of media-libs/openjpeg for bug 711260. Can anything be done about the dependency on openjpeg:0?
Comment 2 Adrian 2020-08-05 02:43:42 UTC
While blender compiles with openjpeg:2, it fails to import display jp2 files in the gui when adding a background image and reports "IMB_ibImageFromMemory: unknown fileformat". When using openjpeg:0 it loads and displays the image properly.

Openjpeg is an optional dependency and it would be possible to disable to jpeg2k USE flag.

I will next test whether blender-2.8x supports openjpeg:2 as if that has support then forcing an upgrade and retiring 2.79b might be a better solution.

    media-gfx/blender: Version bump to 2.83.4
    Blender 2.83.4 works with python 3.7. It may compile with 3.8, but
    blender only supports 3.7 officially as it follows the VFX Reference
    Platform to ensure that user add ons are not broken in the process.
    They plan to introduce 3.8 support in 2021.
    New features include a new interface, the realtime eevee renderer,
    and importing openvdb files created by other packages among others.
    Game engine and Blender Player were removed in 2.80.
    Bug fixes in this version are alembic support, upstream fixes for
    opencollada, requiring openjpeg:2 to avoid security issues, and
    mimeinfo cache is correctly updated. Where these issues remain in
    blender 2.79b, the bug is linked but should be closed only when
    blender 2.79b is removed.
    On my system the docs do not currently compile,
    and the polyfill2d test still fails like 2.79b.
    Blender 2.83 support for draco, embree, oidn, usd and openxr is not yet
    implemented pending development of ebuilds for these packages.
