      Further work to reduce pulsing. · 8064583d
      Paul Wilkins authored
      These changes are specifically targeted at fade transitions to
      static scenes. Here we want to place a GF/ARF immediately
      after the fade and prevent an ARF just  before the fade.
      
      Also some code lines and comment lines shortened to 80 chars
      while I was there.

      Fixed use of motion percentage in KF/GF group calc · 815e1e9f
      Adrian Grange authored
      In both vp8_find_next_key_frame and define_gf_group,
      motion_pct was initialised at the top of the loop before
      next_frame stats had been read in.
      
      This fix sets motion_pct after next_frame stats have
      been read.

      Implement error tracking in the decoder · 67fb3a51
      Henrik Lundin authored
      A new vpx_codec_control called VP8D_GET_FRAME_CORRUPTED. The output
      from the function is non-zero if the last decoded frame contains
      corruption due to packet losses.
      
      The decoder is also modified to accept encoded frames of zero length.
      A zero length frame indicates to the decoder that one or more frames
      have been completely lost. This will mark the last decoded reference
      buffer as corrupted. The data pointer can be NULL if the length is
      zero.

      Fix CQ range and experimental KF sizing changes. · 339c5127
      Paul Wilkins authored
      The CQ level was not using the q_trans[] array to convert
      to a 0-127 range as per min and maxq
      
      Experimental change to try and match the reconstruction
      error for forced key frames approximately to that of the
      previous frame by means of the recode loop. Though this
      may cause extra recodes and the recode behavior has not
      been optimized, it can only happen on forced key frames.

      Testing of modes with Alt Ref frame · 415371c9
      Paul Wilkins authored
      Previously when a frame was being overlaid on a previously coded
      alt ref frame we only checked the alt ref 0,0 mode. Where there is
      a possibility that the alt ref buffer is a filtered frame we should allow
      the other prediction modes as normal or at the least allow use of
      the last frame buffer.

      ARNR filter pointer update bug fix · 2c1b06e6
      Adrian Grange authored
      In cases where the frame width is not a multiple of 16 the
      ARNR filter would go wrong.
      
      In vp8_temporal_filter_iterate_c when updating pointers
      at the end of a row of MBs,  the image size was
      incorrectly used rather than using Num_MBs_In_Row
      times 16 (Y) or 8 (U,V).
      
      This worked when width is multiple of 16 but failed
      otherwise.

      KF/GF Pulsing · c8338ebf
      Paul Wilkins authored
      This change is designed to try and reduce pulsing effects when moving
      with a complex transition like a fade, into an easy or static section in
      an otherwise difficult clip in CQ mode.
      
      The active CQ level is relaxed down to the user entered level for frames that
      are generating less than the passed in minimum bandwidth.

      Limit key frame quantizer for forced key frames. · 55acda98
      Paul Wilkins authored
      Where a key frame occurs because of a minimum interval
      selected by the user, then these forced key frames ideally need
      to be more closely matched in quality to the surrounding frame.

      Fix bug in motion search · 3675b229
      Yunqing Wang authored
      The maximum possible MV in 1/8 pel units is (1<<11), which could
      cause mvcost out of its range that is 1023. Change maximum
      possible MV in 1/8 pel units to (1<<11)-8 will fix this problem.

      Two Pass VBR change · cf7c4732
      Paul Wilkins authored
      Further experiment with restriction of the Q range.
      
      This uses the average non KF/GF/ARF quantizer,  instead
      of just relying on the initial value. It is not such a strong constraint
      but there may be a reduced risk of rate misses.

      CQ Mode · e0846c9c
      Paul Wilkins authored
      The merge includes hooks to for CQ mode and other code
      changes merged from the test branch.
      
      CQ mode attempts to maintain a more stable quantizer within a clip
      whilst also trying to adhere to a guidline maximum bitrate.
      
      The existing target data rate parameter is used to specify the
      guideline maximum bitrate.
      
      A new parameter allows the user to specify a target CQ level.
      
      For normal (non kf/gf/arf) frames, the quantizer will not drop BELOW the
      user specified value (0-63). However, in some cases the encoder may
      choose to impose a target CQ that is above that specified by the user,
      if it estimates that consistent use of the target value is not compatible
      with guideline maximum bitrate.

      Limit Q variability in two pass. · 3af3593c
      Paul Wilkins authored
      In two pass encoding each frame is given an active
      Q range to work with. This change limits how much this
      Q range can be altered over time from the initial estimate
      made for the clip as a whole.
      
      There is some danger this could lead to overshoot or undershoot
      in some corner cases but it helps considerably in regard to
      clips where either there is a glut or famine of bits in some sections,
      particularly near the end of a clip.
