  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • FFmpeg : Jpeg file to AVFrame

    24 octobre 2012, par darja

    I need to join several jpg files into video using FFmpeg library. But I have a problem with reading this files. Here is a function which reads image file and makes AVFrame :

    AVFrame* OpenImage(const char* imageFileName)
    
{
    
    AVFormatContext *pFormatCtx;
    

    
    if(av_open_input_file(&pFormatCtx, imageFileName, NULL, 0, NULL)!=0)
    
    {
    
        printf("Can't open image file '%s'\n", imageFileName);
    
        return NULL;
    
    }       
    

    
    dump_format(pFormatCtx, 0, imageFileName, false);
    

    
    AVCodecContext *pCodecCtx;
    

    
    pCodecCtx = pFormatCtx->streams[0]->codec;
    
    pCodecCtx->width = W_VIDEO;
    
    pCodecCtx->height = H_VIDEO;
    
    pCodecCtx->pix_fmt = PIX_FMT_YUV420P;
    

    
    // Find the decoder for the video stream
    
    AVCodec *pCodec = avcodec_find_decoder(pCodecCtx->codec_id);
    
    if (!pCodec)
    
    {
    
        printf("Codec not found\n");
    
        return NULL;
    
    }
    

    
    // Open codec
    
    if(avcodec_open(pCodecCtx, pCodec)<0)
    
    {
    
        printf("Could not open codec\n");
    
        return NULL;
    
    }
    

    
    // 
    
    AVFrame *pFrame;
    

    
    pFrame = avcodec_alloc_frame();
    

    
    if (!pFrame)
    
    {
    
        printf("Can't allocate memory for AVFrame\n");
    
        return NULL;
    
    }
    

    
    int frameFinished;
    
    int numBytes;
    

    
    // Determine required buffer size and allocate buffer
    
    numBytes = avpicture_get_size(PIX_FMT_YUVJ420P, pCodecCtx->width, pCodecCtx->height);
    
    uint8_t *buffer = (uint8_t *) av_malloc(numBytes * sizeof(uint8_t));
    

    
    avpicture_fill((AVPicture *) pFrame, buffer, PIX_FMT_YUVJ420P, pCodecCtx->width, pCodecCtx->height);
    

    
    // Read frame
    

    
    AVPacket packet;
    

    
    int framesNumber = 0;
    
    while (av_read_frame(pFormatCtx, &packet) >= 0)
    
    {
    
        if(packet.stream_index != 0)
    
            continue;
    

    
        int ret = avcodec_decode_video2(pCodecCtx, pFrame, &frameFinished, &packet);
    
        if (ret > 0)
    
        {
    
            printf("Frame is decoded, size %d\n", ret);
    
            pFrame->quality = 4;
    
            return pFrame;
    
        }
    
        else
    
            printf("Error [%d] while decoding frame: %s\n", ret, strerror(AVERROR(ret)));
    
    }
    
}

    This causes no error but creates only black frame, no image. What is wrong ?

    license should be the type of license

    Follow convention to make it easier for automated license checking utilities to determine which license is used. The license property in bower.json should be the SPDX type of license, in this case "MIT", instead of the URL of the license file.
    

    Closes #544.
