  • 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" (...)

  • Fill a BGR Frame Data in FFMPEG

    23 février 2016, par mFeinstein

    I am following the FFmpeg video enconding example here, but it makes some dummy YUV420P frames and I have a BGR image already captured from a camera.

    I am not sure how to use frame->data[] and frame->linesize[] for filling them with my BGR image instead, so I can encode an H264 video.

    EDIT :

    I have the following code (it’s called for every new picture the camera sends) after Ronald’s answer :

        .............
    
    AVFrame *bgrFrame = av_frame_alloc();
    

    
    bgrFrame->width = originalBGRImage.cols;
    
    bgrFrame->height = originalBGRImage.rows;
    

    
    ret = av_image_alloc(bgrFrame->data, bgrFrame->linesize, bgrFrame->width, bgrFrame->height, AV_PIX_FMT_BGR24, 32);
    

    
    /////////////////////////////////////
    
    // This works and prevents memory leak....if I remove it, it consumes all the RAM....but I can't free this memory here, since I will use it later...
    
    av_freep(&bgrFrame->data[0]);
    
    av_frame_free(&bgrFrame);
    
    return;
    
    /////////////////////////////////////
    

    
    ret = av_image_fill_pointers(bgrFrame->data, AV_PIX_FMT_BGR24, bgrFrame->height, originalBGRImage.data, bgrFrame->linesize);
    

    
    /////////////////////////////////////
    
    // Here is where I am done using the memory so I will want to free it...but this same code crashes the program.
    
    av_freep(&bgrFrame->data[0]);
    
    av_frame_free(&bgrFrame);
    
    return;
    
    /////////////////////////////////////

    So if I remove the av_freep(&bgrFrame->data[0]); at the end of the code I will have a memory leak...but leaving it there crashes....so what’s the correct way to free the used memory ?
