* commit 'a7a17e3f1915ce69b787dc58c5d8dba0910fc0a4': hevc_filter: move some conditions out of loops Conflicts: libavcodec/hevc_filter.c This is possibly less readable than the variant used before. Thus please take a look and if people agree its worse, dont hesitate to revert. See: 83976e40e89655162e5394cf8915d9b6d89702d9 Merged-by: Michael Niedermayer <michaelni@gmx.at>
