Merge commit '65830277d2d2ee3658e1f070a61044fff261ed3e' into release/1.1

* commit '65830277d2d2ee3658e1f070a61044fff261ed3e':
  prores: Add a codepath for decoding errors
  nut: Fix unchecked allocations
  avi: directly resync on DV in AVI read failure
  mov: Don't allocate arrays with av_malloc that will be realloced
  shorten: Extend fixed_coeffs to properly support pred_order 0
  Prepare for 9.11 RELEASE
  avi: properly fail if the dv demuxer is missing
  prores: Reject negative run and level values
  audio_mix: fix channel order in mix_1_to_2_fltp_flt_c
  indeo4: Check the inherited quant_mat
