  libx264: fix indentation.
  vorbis: fix overflows in floor1[] vector and inverse db table index.
  win64: add a XMM clobber test configure option.
  movdec: Parse the dvc1 atom
  ARM: ac3: fix ac3_bit_alloc_calc_bap_armv6
  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()
  pcmenc: Do not set avpkt->size.
  ff_alloc_packet: modify the size of the packet to match the requested size
