  • Revision 1092140379 : No longer use use_lastframe_partitioning speed feature The speedup in rd_pick_p

    6 septembre 2014, par Yunqing Wang

    Changed Paths :
     Modify /vp9/encoder/vp9_speed_features.c



    No longer use use_lastframe_partitioning speed feature

    The speedup in rd_pick_partition() function makes it possible
    to drop use_lastframe_partitioning feature. By doing that, we
    achieve good PSNR gain with small speed loss. Also, this makes
    encoding loop less complicated. The code cleanup patch will
    follow.

    Borg tests showed :
    1. At speed 2,
    stdhd set : 0.201% PSNR gain, 0.133% SSIM gain ;
    derf set : 0.262% PSNR gain, 0.276% SSIM gain.
    2. At speed 3,
    stdhd set : 0.139% PSNR gain, 0.109% SSIM gain ;
    derf set : 0.447% PSNR gain, 0.442% SSIM gain.

    The average speed loss over selected test clips is within 1%
    with the worst case of 4%.

  • avformat/hls : fix segment selection regression on track changes of live streams

    avformat/hls : fix segment selection regression on track changes of live streams
    

    Commit ad701326b43078b90 ("avformat/hls : open playlists immediately when
    AVDISCARD_ALL is dropped") inadvertently caused first_packet to never be
    cleared, causing select_cur_seq_no() to not use the specific code for
    live streams.

    In practice this means that when the user selects a different audio
    track during live stream (i.e. non-VOD) playback, there may be some
    additional delay as the code might select an incorrect segment at first,
    and we have to wait for video to catch audio (if too late segment was
    selected) or to download more following audio segments (if too early
    segment was selected).

    Fix that by restoring the zeroing of first_packet.
