• FFMPEG multi livestream - recorded stream send to different services like YT and Twitch at different time (on different button clicks )

  4 octobre 2022, par Ganesh

  Trying for the last 10 days and still no success, I am creating a python application that will accept the URL and visit that URL using chromium, capture that screen and send that real-time screen recording to different live stream acceptors as youtube live, twitch Twitter, Facebook live or some other sources and many of these could be multiple.

  


  There are two challenges (both challenges depend on a user action like different button clicks) -

  


  

  • The time of starting the Livestream we know only one Livestream acceptor and other acceptors could be sent via another API at any time or may not be sent on the whole live stream.

  


  • Any of the streams could be stopped at any moment including the first one which started the original live streaming service

  


  


  To Solve these challenges I am trying the following process (i took mp4 as a source for simplifying)

  


  

  • create a stream and store it into PIPE.stdout

  


  


  ffmpeg_Command_get_stream = 'ffmpeg -re -i test.mp4 -f flv pipe:1'
ffmpeg_Command_get_stream=ffmpeg_Command_get_stream.split()
pipe = sp.Popen(ffmpeg_Command_get_stream,
            stdout=sp.PIPE,
            stderr=sp.PIPE,
            bufsize=8000000,
            shell=True,
            universal_newlines=True
            )
out,err = pipe.communicate()


  


  


  • and send that stream with the help of FFMPEG to the Livestream acceptor with the click of the youtube Livestream button

    


    ffmpeg_Command_send_stream = ['ffmpeg','-i',pipe.stdout,'-f','flv',RTMPURL_YOUTUBE]

    


  


  


  Update Trying to Explain it a little more :

  


  step 1 - I need a real-time stream from the first command, so I used -re in FFMPEG

  


  step 2 - Use above stream as an input for other command and send that as an output as a Livestream to youtube (or twitch/Facebook), But the second step would happen only when the user click on the button "YT LiveStream", Here the tricky thing is there are multiple buttons (YT LiveStream, Twitch LiveStream, Facebook LiveStream) and user can click any time on any of button, also can click on all button one by one.

  


  

  


  sorry for bad explaination

  


  what I am doing wrong ? , Is this Possible ? or need to go with another process,

  


  any help would be greatly appreciated

  


• 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.
