* commit '6d0beefbf6ee6dbf8efb522a9307e54c6ed5f702': swscale: Do not make ff_ symbols globally visible. rtspdec: use av_strlcpy for writing into fixed size buffer g722enc: fix size argument in memset http: use av_strlcpy instead of strcpy() without size checks avfilter: correct memcpy size avfilter_copy_buf_props() lavc: split asv12 encoder/decoder Conflicts: libavcodec/asvdec.c libavfilter/buffer.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
