[FFmpeg-devel] [PATCH 05/13] libavcodec: Split version.h
Martin Storsjö

Wed Feb 23 16:29:43 EET 2022
This avoids including version.h in all source files, avoiding
unnecessary rebuilds when the version number is bumped. Only
version_major.h is included by the main header, which defines
availability of e.g. FF_API_* macros, and which is bumped much
less often.
