  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • FFMPEG Speed up video (loss of audio is fine)

    14 mai 2015, par adsun

    I’m trying to speed up a video by 2X by using this command.

    ./ffmpeg -i input.mp4 -filter:v setpts=(1/2)*PTS output.mp4

    But I get the following error :

    Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height

    Can someone help me with the correct command to do it ? The input video is a valid MP4 file. It is fine even if there is no audio in the video after speeding up.

  • What's right way to change playback speed with ffmpeg ?

    25 août 2016, par user2440195

    In my project i’m using ffmpeg to playback media. Currently I’m trying to implement changing of playback speed. Will it be right to drop certain packets at high rates, for example not keyframes ? Or I should rely only on changing timestamps and duration, even if performance is low(for example 4k video) and as a consequence increased speed isn’t noticable ?

  • Revision 017baf9f4b : Simplify bilateral filter search for speed Adds an internal buffer in the encod

    15 avril 2015, par Debargha Mukherjee

    Changed Paths :
     Modify /vp9/common/vp9_loopfilter.c


     Modify /vp9/common/vp9_loopfilter.h


     Modify /vp9/decoder/vp9_decodeframe.c


     Modify /vp9/encoder/vp9_bitstream.c


     Modify /vp9/encoder/vp9_encoder.c


     Modify /vp9/encoder/vp9_encoder.h


     Modify /vp9/encoder/vp9_picklpf.c


     Modify /vp9/encoder/vp9_rd.h



    Simplify bilateral filter search for speed

    Adds an internal buffer in the encoder to store the deblocked
    result to help speed up the search for the best bilateral filter.

    Very small change in performance but a lot faster :
    derflr : +0.518%
