  • Record the whole webrtc call in nodejs and stream it into rtmp

    31 juillet 2023, par Matrix 404

    I have a simple peer-to-peer video chat using PeerJS, and I want to stream the entire call to an RTMP server. Do you have any ideas on how to achieve this ? I'm particularly interested in understanding how platforms like StreamYard work on the backend.

    


    The main goal is to stream the video call to an RTMP server.

    


  • Find better VP8 parameters for robustness in UDP streaming with libav/ffmpeg

    24 octobre 2014, par lmNt

    I’m facing some problems in my video chat application, which is using libav libraries. I am sending 1080p videos encoded in VP8 as WebM container via UDP and it works quite well. Most of the time, the decoder on either side recovers from packet losses due to the transmission.

    However at some point in time it just freezes and never recovers again. This happens on both sides eventually. I was searching for VP8 codec parameters to set for increased robustness, when sending over lossy transmission channels. And I combined some of which I found, in order to increase robustness. However, it still freezes after some time of video chat.

    Here are the parameters I am currently using.

      pVidCodecCtx->codec_id     = AV_CODEC_ID_VP8;
    
  pVidCodecCtx->codec_type   = AVMEDIA_TYPE_VIDEO;
    
  pVidCodecCtx->width        = frmQ->pCodecCtx->width; //1920
    
  pVidCodecCtx->height       = frmQ->pCodecCtx->height; //1080
    
  pVidCodecCtx->time_base    = frmQ->pCodecCtx->time_base;
    
  pVidCodecCtx->pix_fmt      = PIX_FMT_YUV420P;
    
  pVidCodecCtx->qmin         = 4;
    
  pVidCodecCtx->qmax         = 56;
    
  pVidCodecCtx->bit_rate     = pVidCodecCtx->width * pVidCodecCtx->height * 6;
    
  pVidCodecCtx->slices       = 8;
    
  pVidCodecCtx->profile      = 3;
    
  pVidCodecCtx->thread_count = 3;
    
  pVidCodecCtx->keyint_min   = 5;
    
  av_dict_set(&pDictCodecOpts, "rc_lookahead", "0", 0);
    
  av_dict_set(&pDictCodecOpts, "quality", "realtime", 0);
    
  av_dict_set(&pDictCodecOpts, "deadline", "realtime", 0);
    
  av_dict_set(&pDictCodecOpts, "max-intra-rate", "0", 0);
    
  av_dict_set(&pDictCodecOpts, "qcomp", "0", 0);
    
  av_dict_set(&pDictCodecOpts, "default", "er", 0);
    
  av_dict_set(&pDictCodecOpts, "error_resilient", "er", 0);
    
  av_dict_set(&pDictCodecOpts, "partitions", "er", 0);

    Most of the parameters I extracted from the ffmpeg code for the vpx encoder.

    Do I also have to set parameters for the decoder in order to increase error resilience ?
    Or am I missing some parameters in the encoder or setting them incorrectly. Any help or hints are greatly appreciated.

  • Remove alternate demo versions.

    21 juillet 2019, par blueimp
    Remove alternate demo versions.

    jQuery UI and Angular 1 are obsolete.
    
The basic and basic plus versions are nice to have, but add unnecessary maintenance overhead.
