  • Revision effd974b16: Limit arf interval for low fpf clips. This patch limits the maximum arf interv

    16 April 2015, by paulwilkins

     Modify /vp9/encoder/vp9_firstpass.c


     Modify /vp9/encoder/vp9_ratectrl.c



    Limit arf interval for low fpf clips.

    This patch limits the maximum arf interval length to
    approximately half a second. In some low fps animations in
    particular the existing code was selecting an overly long interval
    which was hurting visual quality. For a sample problem test clip
    (360P animation , 15fps, 200Kbit/s) this change also improved
    metrics by >0.5 db.

    There may be some clips where this hurts metrics a little, but the
    worst case impact visually is likely to be less than having an
    interval that is much too long. On more normal material at 24
    fps or higher, the impact is likely to be nil/minimal.

    Modified test for auto key frame detection.

    The existing test was triggering a lot of false positives on some types
    of animated material with very plain backgrounds. These were triggering
    code designed to catch key frames in letter box format clips.

    This patch tightens up the criteria and imposes a minimum requirement
    on the % blocks coded intra in the first pass and the ratio between the
    % coded intra and the modified inter % after discounting neutral (flat)
    blocks that are coded equally well either way.

    On a particular problem animation clip this change eliminated a large
    number of false positives including some cases where the old code
    selected kf several times in a row. Marginal false negatives are less
    damaging typically to compression and in the problem clip there are now
    a couple of cases where "visual" scene cuts are ignored because of well
    correlated content across the scene cut.

    Replaced some magic numbers related to this with #defines and added
    explanatory comments.
