• Live streaming and simultaneous local/server video saving with Insta360/Theta 360 camera [closed]

  13 août 2023, par Fornow

  I'm currently working on a project that involves live streaming video from a 360 camera, specifically the Insta360 and Theta models, while also saving the streamed video either locally or on a remote server. I'm relatively new to both live streaming and working with 360 cameras, so I'm seeking guidance on the best approach to achieve this.

  


  My primary goals are as follows :

  


  


  1. Live Streaming : I want to be able to stream the real-time video captured by the 360 camera to a web platform or application, allowing users to experience the immersive 360 content as it happens.

     


  


  2. Simultaneous Video Saving : In addition to live streaming, I also need to save the streamed video. This can either be saved locally on the device running the streaming process or on a remote server. The saved video should ideally retain its 360 nature and high-quality resolution.

     


  


  


  I've been researching various technologies and frameworks like WebRTC for live streaming, but I'm unsure about the compatibility and best practices when dealing specifically with 360 cameras like Insta360 and Theta. Additionally, I'm uncertain about the most efficient way to save the streamed video while maintaining its immersive properties.

  


  If anyone has experience with live streaming from 360 cameras and simultaneously saving the content, could you please provide insights into the following :

  


  

  • Recommended libraries, SDKs, or frameworks for live streaming 360 video from Insta360 or Theta cameras.

  


  • Tips for ensuring the streamed video retains its 360 attributes and high quality.

  


  • Best practices for saving the streamed video either locally or on a remote server while the live stream is ongoing.

  


  


  Any code examples, tutorials, or step-by-step guides would be greatly appreciated. Thank you in advance for your help !

  


• live streaming Buffer data to Rtmp server using ffmpeg with nodejs ?

  13 février 2023, par ashutosh karn

  const ondata = chunk => {
    
    console.log(chunk) //Giving - Buffer 00 00 00 1c 66 74 79 70 64 61..........

    Streaming(chunk,"rtmps://live-api-s.facebook.com:443/rtmp/FB-108963845678778")

    //Streaming function is given below in the next Block.

   
    
  };


  


  i have a function named ondata. who is continuously giving buffer data like this :-

  


  


  ( actually this a buffer of .MP4 file.)

  


  


  <buffer 00="00" 1c="1c" 66="66" 74="74" 79="79" 70="70" 64="64" 61="61" 73="73" 68="68" 69="69" 6f="6f" 36="36" 76="76" 63="63" 31="31" 6d="6d" 34="34" 02="02" ca="ca" 6c="6c" df="df" e2="e2" 16334="16334" more="more" bytes="bytes"></buffer>

  


  <buffer 14="14" 75="75" dd="dd" ea="ea" 7a="7a" 72="72" ef="ef" df="df" 4f="4f" 24="24" cb="cb" 83="83" c3="c3" 85="85" a3="a3" 17="17" 60="60" 26="26" 87="87" 74="74" 0b="0b" 49="49" e4="e4" 6f="6f" 09="09" 65="65" ae="ae" c8="c8" 6c="6c" 7d="7d" 0e="0e" 02="02" b1="b1" 6b="6b" 4a="4a" 63="63" 61="61" ab="ab" d9="d9" 44="44" 22="22" 62="62" 3c="3c" f6="f6" 0d="0d" 8c="8c" c9="c9" b7="b7" 16334="16334" more="more" bytes="bytes"></buffer>

  


  Now I want to stream this buffer data to RTMP Server using FFMPEG

  


  so I doing this :-

  


  const child_process = require('child_process');

   var Streaming = function (chunk, Rtmp_Uri) {

     ffmpeg_process = child_process.spawn('ffmpeg', [
        
         '-re',
         '-i', `${chunk}`,  //Buffer 00 00 00 1c 66 74 79 70 64 61..........
         '-stream_loop','-1',
        '-f', 'flv',
         '-profile:v', 'baseline',
         '-pix_fmt', 'yuv420p',
         '-c:a', 'aac',
         '-acodec', 'mp3',
        '-ar', '44100',
         '-b:a', '128k',
         '-vcodec', 'libx264',
         '-bufsize', '600k',
         '-vb', '400k', 
        '-maxrate', '3000k',
         '-preset', 'ultrafast',
         '-r', '30',
         '-g', '30',
        Rtmp_Uri       //"rtmps://live-api-s.facebook.com:443/rtmp/FB-1089638456787788-0..
                          AbzJ3chy775fhjjjkW2";
     ]);
     return ffmpeg_process;

}


  


  when I run this Streaming function nothing happens.

  


  so can anyone tell me how to stream the buffer to the Rtmp server ? or any FFmpeg command that stream buffer data to rtmp server ?

  


  Thanks in Advance.
