From 26325cceb020608928800b8fe5f4a0f6e60468eb Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Sat, 27 Aug 2022 17:31:44 +0200 Subject: [PATCH] avutil/internal: Remove unused FF_SYMVER They are unused since d63443b9684fa7b3e086634f7b44b203b6d9221e. Furthermore, they were always in the wrong header: libavutil/internal.h is auto-included almost everywhere, but FF_SYMVER would only ever be used at a few places, so a proper header of its own would be appropriate for it.
