Merge remote-tracking branch 'cus/stable'

* cus/stable:
  ffplay: remove redundant !codec check
  ffplay: only initialize codec opts before using it
  ffplay: always free buffersink_params in configure_video_filters
  ffplay: remove uneeded format filter, buffersink format is set
  ffplay: check for buffersink_params allocation success
  ffplay: always free inputs and outputs in configure_filtergraph
  ffplay: fill the unused part of the window with black
  ffplay: add update parameter to fill_rectangle
