* qatar/master: h264: Factorize declaration of mb_sizes array. vsrc_buffer: when no frame is available, return an error instead of segfaulting. configure: add dl to frei0r extralibs. dsputil x86: use SSE float instruction instead of SSE2 integer equivalent dsputil x86: remove deprecated parameter from scalarproduct_int16 prototype vp8dsp x86: perform rounding shift with a single instruction fate: add BMP tests. swscale: handle complete dimensions for monoblack/white. aacenc: Mark deinterleave_input_samples argument as const. vf_unsharp: Mark readonly variable as const. h264: fix 4:2:2 PCM-macroblocks decoding Conflicts: configure libavcodec/h264.h libavcodec/x86/dsputil_mmx.c libavfilter/vf_unsharp.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
