* qatar/master: (23 commits) ac3enc: correct the flipped sign in the ac3_fixed encoder Eliminate pointless '#if 1' statements without matching '#else'. Add AVX FFT implementation. Increase alignment of av_malloc() as needed by AVX ASM. Update x86inc.asm from x264 to allow AVX emulation using SSE and MMX. mjpeg: Detect overreads in mjpeg_decode_scan() and error out. documentation: extend documentation for ffmpeg -aspect option APIChanges: update commit hashes for recent additions. lavc: deprecate FF_*_TYPE macros in favor of AV_PICTURE_TYPE_* enums aac: add headers needed for log2f() lavc: remove FF_API_MB_Q cruft lavc: remove FF_API_RATE_EMU cruft lavc: remove FF_API_HURRY_UP cruft pad: make the filter parametric vsrc_movie: add key_frame and pict_type. vsrc_movie: fix leak in request_frame() lavfi: add key_frame and pict_type to AVFilterBufferRefVideo. vsrc_buffer: add sample_aspect_ratio fields to arguments. lavfi: add fieldorder filter scale: make the filter parametric ...
