# Subslot: libavutil major.libavcodec major.libavformat major
# Since FFmpeg ships several libraries, subslot is kind of limited here.
# Most consumers will use those three libraries, if a "less used" library
# changes its soname, consumers will have to be rebuilt the old way
# (preserve-libs).
# If, for example, a package does not link to libavformat and only libavformat
# changes its ABI then this package will be rebuilt needlessly. Hence, such a
# package is free _not_ to := depend on FFmpeg but I would strongly encourage
# doing so since such a case is unlikely.
