  swscale: K&R formatting cosmetics for Blackfin code
  frwu: lowercase the FRWU codec name
  movdec: fix dts generation in fragmented files
  fate: make acodec-ac3_fixed test output raw AC3
  APIchanges: add missing commit hashes
  swscale: implement MMX, SSE2 and AVX functions for RGB32 input.
  ra144enc: drop pointless "encoder" from .long_name
  bethsoftvideo: fix palette reading.
  mpc7: use av_fast_padded_malloc()
  mpc7: simplify handling of packet sizes that are not a multiple of 4 bytes
  doc: decoding Forward Uncompressed is supported
  Fix a typo in the x86 asm version of ff_vector_clip_int32()
