  rtpenc: Add support for G726 audio
  rtpdec: Interpret the different G726 names as bits_per_coded_sample
  rtpenc: Change rtp_send_samples to handle sample sizes other than even bytes
  rtpenc: Cast a rescaling parameter to int64_t
  h264: cap max has_b_frames at MAX_DELAYED_PIC_COUNT - 1.
  ARM: fix indentation in ff_dsputil_init_neon()
  ARM: NEON put/avg_pixels8/16 cosmetics
  ARM: add remaining NEON avg_pixels8/16 functions
  ARM: clean up NEON put/avg_pixels macros
  fate: split acodec-pcm into individual tests
  swscale: #include "libavutil/mathematics.h"
  pmpdec: don't use deprecated av_set_pts_info.
  rv34: align temporary block of "dct" coefs
  Add PlayStation Portable PMP format demuxer
  proto: Realign struct initializers
  proto: Use .priv_data_size to allocate the private context
  mmsh: Properly clean up if the second ffurl_alloc failed
  rtmp: Clean up properly if the handshake failed
  md5proto: Remove the get_file_handle function
