  • 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 (...)

  • ffmpeg speed up video - Windows

    11 avril 2016, par Flash Thunder

    In manual it says :

    ffmpeg -i input.mkv -filter:v 'setpts=0.5*PTS' output.mkv

    But when I run :

    ffmpeg -i input.mp4 -filter:v 'setpts=0.5*PTS' speedup.mp4

    I get an error :

    [AVFilterGraph @ 0000000002500600] No such filter: 'setpts=0.5*PTS'
    
Error opening filters!

    Not sure if it means that filter can’t be opened at all or simply this filter is not available.

    How do I run it correctly ? Or maybe my release does not support it, then where can I get the release that would work right ? Win32/x64 binary

  • Revision 53ff43adc3 : Prunes out full-rd computation based on modeled rd Adds a speed feature to elim

    9 juillet 2013, par Deb Mukherjee

    Changed Paths :
     Modify /vp9/common/vp9_blockd.h


     Modify /vp9/encoder/vp9_onyx_if.c


     Modify /vp9/encoder/vp9_onyx_int.h


     Modify /vp9/encoder/vp9_rdopt.c



    Prunes out full-rd computation based on modeled rd

    Adds a speed feature to eliminate full-rd computation if the modeled
    rd or rd based on a different parameter in the same mode is already
    a lot larger than the best rd yet.

    Specifically, only search the sharp and smooth filters if the modeled
    rd cost based on the regular filter is within a certain factor of the
    best rd cost so far. Also, skip full-rd computation of non splitmv
    inter modes if the modeled rd cost based on pred error is within the
    same factor of the best rd cost so far.

    Also adds some enhancements in the rd search for splitmv mode to
    speed things up by early breakouts. Negligible impact on performance.

    Resuts on derfraw300 :
    psnr : -0.013% with the splitmv enhancements, -0.24% with the rd
    breakout feature on.
    speedup : 6% with splitmv enhancements, 20% with also residual breakout
    (tested on football sequence at 600 Kbps)
