  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

    12 juillet 2013, par Deb Mukherjee

    Changed Paths :
     Modify /vp9/encoder/vp9_block.h


     Modify /vp9/encoder/vp9_encodemv.c

    Reworked the auto_mv_step_size speed feature

    This patch modifies the auto_mv_step_size speed feature to
    use a combination of the maximum magnitude mv from the last
    inter frame, and the maximum magnitude mv for the two reference
    mvs with the same reference. For arf frames, the max mav step
    for the resolution is used.
    The bounds therefore are slightly tighter. The feature is made
    a speed 1 feature.

    Rebased.

    Results (when this feature is turned on over speed 0) :
    derfraw300 : -0.046% psnr, about 5+% speedup
    (tested on football : goes from 4m30.760s to 4m17.410s).

    17 juillet 2013, par Ronald S. Bultje

    Changed Paths :

    Best_rd breakout in rd partition search.

    About 15% faster for bus (speed 0) first 50 frames @ 1500kbps, which
    goes from 1min36 to 1min24. Results become slightly better (+0.2% on
    derf/yt, +0.4% on hd), probably because of a bugfix for skipmode in
    super_block_yrd(). Overall speed change (on derfraw300) is roughly
    - 13%. This can probably be improved further by caching best_yrd
    between partition searches. Also, we might be able to get more
    speedups by always doing PARTITION_NONE before PARTITIONS_SPLIT, not
    just at the sb8x8 level.
