  • Extracting KLV data from mp2 stream using C++ and ffmpeg

    18 juin 2019, par Douglas

    I have an mp2 stream that has klv metadata. I stored the klv in a file using ffmpeg command line :

    ffmpeg -i input.mpg -map data-re -codec copy -f data output.klv

    I now want to do this in c++. So, I have

    FFMPEG setup …..

    Then the main loop

    // Read frames
    
while(av_read_frame(pFormatCtx, &packet) >= 0)
    
{
    
    // Is this a packet from the video stream?
    
    if(packet.stream_index == videoStream)
    
    {
    
        // Decode video frame
    
        avcodec_decode_video2(pCodecCtx, pFrame, &frameFinished, &packet);
    

    
        // Did we get a video frame?
    
        if(frameFinished)
    
        {
    
            // Convert the image from its native format to RGB
    
            sws_scale(sws_ctx, (uint8_t const * const *)pFrame->data,
    
                                pFrame->linesize, 0, pCodecCtx->height,
    
                                pFrameRGB->data, pFrameRGB->linesize);
    

    
            QImage myImage(pFrameRGB->data[0], pCodecCtx->width, pCodecCtx->height, QImage::Format_RGB888);
    

    
            QPixmap img(QPixmap::fromImage(myImage.scaled(ui->label->width(),ui->label->height(),Qt::KeepAspectRatio)));
    

    
            ui->label->setPixmap(img);
    
            QCoreApplication::processEvents();
    
        }
    
    }
    
    else // klv stream
    
    {
    
        // Decode klv data
    
        qDebug() << packet.buf->size;
    
        for(int i=0; isize; i++)
    
        {
    
            qDebug() << packet.buf->data[i];
    
        }
    
    }

    The resulting klv output is different - I must be doing something wrong processing the packet. The frames are good and I’m viewing it in a qt label - so my ffmpeg setup is working on images but not the klv data.

  • Extract MXF file data using python

    28 juin 2022, par Rex

    Is there any way to extract MXF file data using python ?

    


    All I want to do is get data like video duration, actual video stream and if possible the voice in mp3 or any audio format from an MXF file.
