  • Write silence audio data into file ffmpeg C++

    14 août 2015, par Kaidul Islam

    I want to write silence/zeroed audio sampled data into mov media container file inside audio data. My audio data is G711 linear PCM-mulaw encoded data with one channel. Currently my code looks like :

    AVFrame* pSilentData = av_frame_alloc();
    
memset(&pSilentData->data[0], 0, iDataSize);
    
pkt.data = (uint8_t*) pSilentData;
    
pkt.size = iDataSize;
    

    
// ...
    

    
av_freep(&pSilentData->data[0]);
    
av_frame_free(&pSilentData);

    But this sounds noise like dot dot instead of silence. What’s the problem ?

  • recive klv data from a ffmpeg mulsticast

    5 avril 2019, par diego

    I am trying to get the klv data from a .mpeg.

    I tried this command and it works perfectly :

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

    Now I would like to open two CMD and transfer it by multicast, how could I do this ? i tried many comands like next ones, but I do not get the same .klv

    sender : ffmpeg -i video.mpeg -c copy -f mpegts udp://239.1.1.1:49410

    receiver : ffmpeg -i udp://239.1.1.1:49410 -map 0 -codec copy -f data data.klv

    I am new with ffmpeg and I do not know exactly what I need to change to get exactly whay I get in the first command.

    Thanks

  • AVFrame data format

    10 mars 2021, par Валентин Никин

    I process the raw data from AVFrame.data. Pixel format of this frames is AV_PIX_FMT_YUV420P. I want to understand in what range of values is this data located.

    


    Seems UV (in YUV scheme) must be in [-128, 128] range, CbCr (in YCbCr) must be in [0, 255]. What scheme used in FFmpeg ?
