  mss2: only use error correction for matching block counts
  
  This fixes a heap-buffer-overflow in ff_er_frame_end when decoding mss2
  with coded_width/coded_height larger than width/height.

  binkaudio: switch to the new send/receive API
  
  It is more natural for this codec and allows to avoid awkward constructs
  like "consuming 0 bytes from input". Also, keep a reference to the input
  packet to avoid unnecessary copying.

• pthread_frame : do not run hwaccel decoding asynchronously unless it’s safe

  pthread_frame: do not run hwaccel decoding asynchronously unless it's safe
  
  Certain hardware decoding APIs are not guaranteed to be thread-safe, so
  having the user access decoded hardware surfaces while the decoder is
  running in another thread can cause failures (this is mainly known to
  happen with DXVA2).
  
  For such hwaccels, only allow the decoding thread to run while the user
  is inside a lavc decode call (avcodec_send_packet/receive_frame).
