  rv34: Fix potential overreads
  rv34: Fix buffer size used for MC of B frames after a resolution change
  rv34: Avoid NULL dereference on corrupted bitstream
  rv10: Reject slices that does not have the same type as the first one
  vf_yadif: add an option to enable/disable deinterlacing based on src frame "interlaced" flag

  vsrc_color: add @file doxy
  vsrc_buffer: remove duplicated file description
  eval: implement not() expression
  eval: add sqrt function for computing the square root
