Unify blend file thumbnail extraction
Open, Confirmed, LowPublic


Currently there are two utilities for extracting thumbnails from Blend files.

  • ./source/blender/blendthumb/src/BlenderThumb.cpp
  • ./release/bin/

This is causing a problem for adding a new compression method D4402: LZ4 Compression for blend file IO because we need to support a new kind of decompression for both.

Besides this, Python doesn't support LZ4, making it likely we would need to write a new utility in C/C++ anyway.

This task proposes to share use a single thumbnail extraction utility (probably based on BlenderThumb.cpp) which all platforms can share.
