Creating farms of unique websites
13 avril 2011, parMediaSPIP 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" (...)

Simplify bilateral filter search for speedAdds 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 :

What's right way to change playback speed with ffmpeg ?
25 août 2016, par user2440195In 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 ?

FFMPEG Speed up video (loss of audio is fine)
14 mai 2015, par adsunI’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.
