    Dans beaucoup d’endroits du site, logos et images sont redimensionnées pour correspondre aux emplacements définis par les thèmes. L’ensemble des ces tailles pouvant changer d’un thème à un autre peuvent être définies directement dans le thème et éviter ainsi à l’utilisateur de devoir les configurer manuellement après avoir changé l’apparence de son site.
    Ces tailles d’images sont également disponibles dans la configuration spécifique de MediaSPIP Core. La taille maximale du logo du site en pixels, on permet (...)

  • 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" (...)

  • LibVLC DXVA2 Windows C++ Hardware Acceleration

    15 novembre 2016, par Sergiu Vlad

    I want to decode a h264 RTSP stream using DXVA2 Accelerated decoder. In VLC it does work but in my code have the following output :

    avcodec generic warning: threaded frame decoding is not compatible with DXVA2, disabled
    
avcodec generic debug: available hardware decoder output format 61 (dxva2_vld)
    
avcodec generic debug: available hardware decoder output format 128 (d3d11va_vld)
    
avcodec generic debug: available software decoder output format 12 (yuvj420p)
    
core generic debug: looking for hw decoder module matching "any": 1 candidates
    
core generic debug: no hw decoder modules matched

    Is this a problem with NV12 conversion ? Is there a way to force DXVA2 ?

    Thanks

  • Crash at sws_scale when converting AVFrame to RGB32

    1er mars 2017, par WLGfx

    Crashing at sws_scale when converting an AVPicture

    At first I was using sws_scale to actually scale the frames up but the cpu overhead was too high, so I decided to just convert the frames and adjust the QImage size instead. Before it was working and I was getting the video displaying when rendered, but now it crashes at sws_scale.

    This is written in Qt for Android and using FFMpeg 3.1.4.

    Also, is there another way around not using the deprecated functions ?

    Does anybody know why I am getting the crash at sws_scale ?

    The class for the VideoFrameCopy

    class VideoFrameCopy {
    
public:
    
    VideoFrameCopy() {}
    
    VideoFrameCopy(AVFrame *frame) { copyAVFrame(frame); }

    int interlaced_frame;

  • watermark image get rotated on video using ffmpeg- android

    24 avril 2017, par Pratik Deogade

    I am trying to add water mark on my video in android, i am successfull in adding it but the problem is water image get rotated by 90 degree clock wise

    here is my command

    String[] complexCommand = "ffmpeg","-y" ,"-i", "/sdcard/Vid.mp4","-strict","experimental", "-vf", "movie=/sdcard/watermarka.png [watermark] ; [in][watermark] overlay=main_w-overlay_w-10:10 [out]","-s", "320x2400","-r", "30", "-b", "15496k", "-vcodec", "mpeg4","-ab", "48000", "-ac", "2", "-ar", "22050", "/sdcard/out.mp4" ;

    the output i am getting is :
