  • Real fft error - ffmpeg

    22 juin 2016, par Steva

    I am trying to use ffmpegs fft utility for audio samples called real fft(rdft).

    But I have SIGSEGV error. Code is very simple.

     static void fft(float* data){
    
    RDFTContext * ctx = av_rdft_init(Globals::WindowSizePower, DFT_R2C)
    
    av_rdft_calc(ctx, data);
    
    av_rdft_end(ctx);
    
    av_free(ctx);
    
  }

    Defined constants are

    static const int WindowSize = 1024;
    
static const int WindowSizePower = 10;

    Can someone tell me what I am doing wrong ? I tried to find example on internet where this ffmpeg utility is used but I didnt find any.

    EDIT :

    This is function which call this function

    void fftInit(float* correction){
    
        m_fft_data = new float[Globals::WindowSize]();
    
        memcpy(m_fft_data, correction, sizeof(float)*Globals::WindowSize);
    
        for(int i = 0; i < Globals::WindowSize; ++i){
    
            m_fft_data[i] *= m_data[i];
    
        }
    

    
        FFMPEGFFT::fft(m_fft_data);
    
    }

    Input data is properly allocated. I tested extracted data before coming to this part.

  • How to merge and synchronize the audio with the processed video for real time streaming ?

    24 septembre 2019, par Padfoot

    I am detecting objects on a RTMP video+audio stream. The output, object detected video stream doesn’t contain audio in it. How to merge the audio back to the output for real-time video+object streaming output ?

    I am using YOLO in darknet C framework. The FPS is 40. Also the output stream needs to be in 25-30 FPS.
