+# 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.
