      Prevent left_block_mode stepping into left tile · c8079494
      Jingning Han authored
      This commit uses left_available flag to decide if the left mode_info
      struct is available for left_block_mode. As discussed with James
      Zern (jzern@), this prevents the codec from fetching mode_info from
      blocks in the left tile, which although effectively not used might
      present concerns for multi-threaded tile decoding.
      
      This is NOT a bit-stream change.

      Modified no memory rate control. · eec3def7
      Paul Wilkins authored
      This 2-pass rate control setting allocates bits based
      on first pass stats to each kf group, gf group and individual
      frame but does not correct the bits left and allocation after
      each frame.
      
      In other words it recommends a bit allocation for each frame
      but does not try and correct any over or under spend on a
      frame over the remainder of the clip. This reduces the accuracy
      of rate control in terms of hitting an average bitrate but prevents
      problems that may arise because early frames either use to many
      or too few bits. This mode is currently more inclined to undershoot
      than overshoot (particularly at higher data rates).
      
      Also minor changes to rate of adaption when recode loop is not
      enabled.
      
      This mode is currently enabled by default for VBR.
      It gives the following % performance gains.
      
      derf +0.467, +1.072
      yt 2.962, 2.645
      stdhd 1.682, 1.595,
      yt-hd 2.3, 2.174

      Reduced delta for kf/gf/arf when at maxq. · a2769bb7
      Paul Wilkins authored
      Delta reduced because of concern about popping on some
      very hard clips.
      
      Also allow some frame recode at speed 2 for kf/gf/arf.

      Fix d207 intra prediction SSSE3 functions · dd510428
      Yunqing Wang authored
      This patch fixed a bug that caused 32bit PIC build mismatch. The
      stack pointer was modified after "GET_GOT". Loading left pointer
      from a hard-coded position gave wrong result.
