  • 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" (...)

    I want to use the mic from the seeed-2mic-voicecard.

    


    Thanks for the help

    swresample/resample : optimize exact_rational=on:linear_interp=on case

    separate dsp.resample to dsp.resample_common and dsp.resample_linear
    
and choose to call faster resample_common even when linear_interp=on
    
when c->frac and c->dst_incr_mod are both zero
    

    speed up resampling when exact_rational and linear_interp are both
    
enabled because exact_rational force c->frac and c->dst_incr_mod to
    
be zero when soft compensation does not happen
