  • 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.

  • Revision 6253cc9279 : Speed setting review. Substantial reworking of the speed vs quality trade offs

    1er octobre 2013, par Paul Wilkins

    Changed Paths :
     Modify /vp9/encoder/vp9_encodeframe.c


     Modify /vp9/encoder/vp9_onyx_if.c


     Modify /vp9/encoder/vp9_onyx_int.h


     Modify /vp9/encoder/vp9_rdopt.c



    Speed setting review.

    Substantial reworking of the speed vs quality trade offs for
    speed 1 and 2.

    In this patch I am attempting to freeze the "quality" meaning of
    speeds 1 and 2 relative to speed 0 so that in future we can
    better evaluate progress.

    I am targeting :
    Speed 1 quality -5% vs speed 0.
    Speed 2 quality -10% vs speed 0

    It is inevitable that quality will still fluctuate a little as we adjust
    settings and add new features, but we will attempt to keep as
    close as possible to these values. Above speed 2 things will remain
    a bit more fluid for now.

    In this patch speed 1 is approximately 4-5x as fast as speed 0. This
    is similar to before but the quality hit is a lot less. Likewise speed 2
    is approximately 2x as fast as speed 1 but is similar in quality to the
    previous speed 1 configuration.

    Also slight change to behavior of FLAG_EARLY_TERMINATE to insure
    all reference frames get at least one rd test. Important for very low
    variance regions.

    WIP :- Added a new speed level with old speed 4 becoming speed 5.
    Speed 3 and 4 tradeoffs still WIP

    Thanks in advanced.

  • How Opensl es on android control the audio speed ?

    6 décembre 2013, par user1882379

    I use NDK+FFMPEG on android to decode an video file, and transfer the decoded pcm data to opensles for play audio .I register the opengles for the pcm format：

      SLDataFormat_PCM format_pcm;
    
    format_pcm.formatType = SL_DATAFORMAT_PCM;
    
    format_pcm.numChannels = channel;
    
    format_pcm.samplesPerSec = rate * 1000;
    
    format_pcm.bitsPerSample = SL_PCMSAMPLEFORMAT_FIXED_16;
    
    format_pcm.containerSize = SL_PCMSAMPLEFORMAT_FIXED_16;

    also I convert the decoded pcm data to AV_SAMPLE_FMT_S16 format using swr_convert(...), but the play audio speed is very fast. but if you use sdl , the play speed is normal. It would be sdl can control the play audio speed, but opensles can not. I do not know whether it is my mistake using opensles or opensles can not control audio speed(need application to control)？
