  • FFmpeg Stream RTSP input and save to file at the same time using nodejs

    26 juin 2015, par Ofir Attia

    I am using node-rtsp-stream module to stream RTSP to web with nodejs.
    I am streaming RTSP source with ffmpeg, for example RTSP SOURCE - EXAMPLE

    I know that I can save one or many inputs to many outputs but I dont know if there is option to stream the input and save it to file at the same time without executing two process of ffmpeg.
    With the following example I am able to stream the RTSP source 

    ffmpeg -i rtsp-url -rtsp_transport tcp -f  mpeg1video -b:v 800k -r 30  

    On the module is look like that :

    this.stream = child_process.spawn("ffmpeg", [ "-i", this.url, "-rtsp_transport", "tcp",'-f', 'mpeg1video', '-b:v', '800k', '-r', '30', '-'], {
    
      detached: false
    
    });
    
    ff =child_process.spawn("ffmpeg", [ "-i", this.url,  '-b:v', '800k', '-r', '30', '1.mp4'], {
    
      detached: false
    
    });
    
    this.inputStreamStarted = true;
    
    this.stream.stdout.on('data', function(data) {
    
      return self.emit('mpeg1data', data);
    
    });
    
    this.stream.stderr.on('data', function(data) {
    
      return self.emit('ffmpegError', data);
    
    });

    As you can see I am using two process of ffmpeg to do what I want but
    If anyone faced with this issue and solve it with one command ( process ), I would like to get some suggestions.
    How to stream RTSP source and save it to file at the same time.

    for more information about the module I use :

  • Save and re-stream RSTP video as straight UDP

    30 septembre 2013, par user1701362

    I am trying to write a program that will connect to a RTSP video source and redirect the video data to another location using UDP. I am also saving the RTSP packets to be able to replay the video stream at a latter moment in time as well. Right now my program can connect to the RTSP video stream and redirect and save, but when I try to look at the redirected video I get nothing using VLC.

    Currently the program just strips out the datagram from the RTSP video packets it receives in its open UDP socket and re-sends them using this code using the boost asio library.

    newVideoSocket->send_to(&dg.data[0], dg.data.size() ,Endpoint);

    When I look at the traffic using Wireshark I see that it is actually sending the data to the new address and it is recognized as a UDP packet, but when I try and view the video using VLC nothing happens. The video stream is Mpeg4 with the video encoded as H.264 and VLC can play it.

    I have tried to connect to the redirected stream as UDP and as RTP at both multicast and unicast addresses but have had no success. Do I need to add or take something out of the datagram before I resend it ? Or is it something wrong with how I am tring to view it in VLC ? Thanks for the help.
