* qatar/master: libspeexenc: add supported sample rates and channel layouts. Replace usleep() calls with av_usleep() lavu: add av_usleep() function utvideo: mark interlaced frames as such utvideo: Fix interlaced prediction for RGB utvideo. cosmetics: do not use full path for local headers lavu/file: include unistd.h only when available configure: check for unistd.h log: include unistd.h only when needed lavf: include libavutil/time.h instead of redeclaring av_gettime() Conflicts: configure doc/APIchanges ffmpeg.c ffplay.c libavcodec/utvideo.c libavutil/avutil.h Merged-by: Michael Niedermayer <michaelni@gmx.at>
