      rv34: set mb_num_left to 0 after finishing a frame · 5484170a
      Ronald S. Bultje authored
      Prevents running error resilience on a previous frame which will write
      to the pic->mb_type[] array of the previous image. The array might
      already be re-used for a new image in a subsequent thread, thus cause
      two threads to write to the same pic->mb_type[] array, causing a race
      condition which can crash in rv34_decode_cbp(), called by
      rv34_decode_inter_mb_header() (which accesses mb_type[] twice,
      assuming values are maintained, which the race condition breaks).

      rv34: fix and optimise frame dependency checking · 3547f8e8
      Janne Grunau authored
      The sporadic threading errors during fate-rv30 were caused by calling
      ff_thread_await_progress with mb row -1 as argument. That returns
      immediately since progress is initialized to -1. Not yet computed
      motion vectors from the reference could be used for the first
      macroblocks.

      rv34: DC-only inverse transform · 3faa303a
      Christophe GISQUET authored
      When decoding coefficients, detect whether the block is DC-only, and take
      advantage of this knowledge to perform DC-only inverse transform.
      
      This is achieved by:
      - first, changing the 108x4 element modulo_three_table into a 108 element
        table (kind of base4), and accessing each value using mask and shifts.
      - then, checking low bits for 0 (as they represent the presence of higher
        frequency coefficients)
      
      Also provide x86 SIMD code for the DC-only inverse transform.

      rv34: use get_bits_left() · e652cc96
      Janne Grunau authored
      It is not necessary to store the bit stream length in a RV34DecContext
      field.
