FFmpeg/libavcodec/arm/fft_init_arm.c
Michael Niedermayer 92ef4be4ab 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
