  • 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" (...)

  • Getting color mismatch while converting from NV12 raw data to H264 using FFMPEG

    29 janvier 2019, par Harshil Makwana

    I am trying to convert NV12 raw data to H264 using hw encoder of FFMPEG.

    to pass raw data to encoder I am passing AVFrame struct using below logic :

        uint8_t * buf;
    
    buf = (uint8_t *)dequeue();
    
    frame->data[0] = buf;
    
    frame->data[1] = buf + size;
    
    frame->data[2] = buf + size;
    
    frame->pts = frameCount;
    
    frameCount++;

    but using this logic, I am getting, color mismatched H264 data,

    Can someone tell me , How to pass buffer to AVFrame data ?

    Thanks in Advance,
    Harshil

  • How to demux mpegts data and mux it in mp4 using ffmpeg in c++ ?

    29 septembre 2016, par M.Taha

    Hello I am streaming mpegts data and receaving mpegts data at other end . And i am able to demux mpegts data seperately into h264 and aac. Now i have to mux this h264 and aac in mp4 format, I am able to do muxing of h264 alone in mp4 but as soon as i am muxing h264 with aac in mp4 my program gets crashed.

    Help me in doing so. Any kind of help will be really appreciated.

  • ffmpeg how to save decoded audio data to pcm

    21 avril 2015, par Jason

    I have succeed decode audio data from a mp4 using avcodec_decode_audio4， I want to save the decoded frames,so I tried below

    if (got_frame) {
    
  int size;
    
  uint8_t *data;
    
  int ref = 0;
    
  ret = swr_convert(swr, &data, frame->nb_samples, (const uint8_t **)frame->extended_data, frame->nb_samples);
    
  //fwrite(data, 1, frame->nb_samples, fp_audio);
    
  ref++;
    
  int szie = av_samples_get_buffer_size(NULL, 2, 1024, AV_SAMPLE_FMT_FLTP, 1);
    

    
  for (int i = 0; i < frame->linesize[0]/4; i++)
    
  {
    
    fwrite(frame->data[0] + 4*i, 1, 4, fp_audio);
    
    fwrite(frame->data[1] + 4*i, 1, 4, fp_audio);
    
    ref++;
    
  }
    

    

    

    
  av_frame_unref(frame);
    
}

    but the pcm sounds strange, I also tried directed write as follows

    fwrite(frame->data[0], 1, frame->linesize[0], fp_audio);

    or :

    fwrite(frame->data[0], 1, frame->linesize[0], fp_audio);
    
fwrite(frame->data[1], 1, frame->linesize[0], fp_audio);

    I know that the decoded pcm is AV_SAMPLE_FMT_FLTP
    any help would be appreciated
