Merge remote-tracking branch 'qatar/master'
* qatar/master: ARM: allow runtime masking of CPU features dsputil: remove unused functions mov: Treat keyframe indexes as 1-origin if starting at non-zero. mov: Take stps entries into consideration also about key_off. Remove lowres video decoding Conflicts: ffmpeg.c ffplay.c libavcodec/arm/vp8dsp_init_arm.c libavcodec/libopenjpegdec.c libavcodec/mjpegdec.c libavcodec/mpegvideo.c libavcodec/utils.c libavformat/mov.c Merged-by: Michael Niedermayer <michaelni@gmx.at>
