Code Issues Releases Activity

Merge remote-tracking branch 'qatar/master'

Browse Source 
* qatar/master:
  APIchanges: fill in missing hashes and dates.
  Add an APIChanges entry and bump minor versions for recent changes.
  ffmpeg: print the low bitrate warning after the codec is openend.
  doxygen: Move function documentation into the macro generating the function.
  doxygen: Make sure parameter names match between .c and .h files.
  h264: move fill_decode_neighbors()/fill_decode_caches() to h264_mvpred.h
  H.264: Add more x86 assembly for 10-bit H.264 predict functions
  lavf: fix invalid reads in avformat_find_stream_info()
  cmdutils: replace opt_default with opt_default2() and remove set_context_opts
  ffmpeg: use new avcodec_open2 and avformat_find_stream_info API.
  ffplay: use new avcodec_open2 and avformat_find_stream_info API.
  cmdutils: store all codec options in one dict instead of video/audio/sub
  ffmpeg: check experimental flag after codec is opened.
  ffmpeg: do not set GLOBAL_HEADER flag in the options context
