• How to configure Red5-Server 1.0.5 RELEASE and Red5-Client 1.0.5 RELEASE ? [on hold]

  25 juillet 2015, par Gerardo Barzola

  I have a big problem. Recently my friend and i we would try to configure Red5-client 1.0.5 RELEASE and Red5-server 1.0.5 RELEASE.

  We are using :

  • Ubuntu 12.04.5 LTS
  • ruby 2.0.0p643
  • Rails 4.2.1
  • Server Apache/2.2.22 (Ubuntu)
  • Phusion Passenger 5.0.7
  • FFMPEG version git-2015-05-22-ebb08f3

  And the configuration of the red5 server is good.
  But we have problems to configure red5 client. We dont know how to install and configure. We need to configure and webcamera screenshot and webcamera capture video.

  Do you give me and steps that how to install and configure ?

  Thanks a lot,

  Gerardo

• Node.js, stream pipe output data to client with socket io-stream

  22 mai 2018, par Empha

  Sorry for a repeating topic, but i’ve searched and experimented for 2 days now and i haven’t been able to solve the problem.

  I am trying to live stream pictures every 1 second to a client via socket.io-stream using the following code :

  var args = [
  
      "-i",
  
      "/dev/video0",
  
      "-s",
  
      "1280x720",
  
      "-qscale",
  
      1,
  
      "-vf",
  
      "fps=1",
  
      config.imagePath,
  
      "-s",
  
      config.imageStream.resolution[0],
  
      "-f",
  
      "image2pipe",
  
      "-qscale",
  
      1,
  
      "-vf",
  
      "fps=1",
  
      "pipe:1"
  
  ];
  
  camera = spawn("avconv", args);    // avconv = ffmpeg

  The settings are good, and the process writes to stdout successfully. I capture all outgoing image data using this simplified code :

  var ss = require("socket.io-stream");
  
  camera.stdout.on("data", function(data) {
  
      var stream = ss.createStream();
  
      ss(socket).emit("img", stream, "newImg");
  
      // how do i write the data-object to the stream?
  
      // fs.createReadStream(imagePath).pipe(stream);
  
  });

  "socket" comes from the client using the socket.io-package, no problem there. So what i am doing is that i listen to the stdout-pipe for the "data" event. That data gets passed to the function above. That means that at this stage "data" is not a stream, its a "<buffer></buffer>code>"-object, and therefore i cannot stream it like i could previously using the commented createReadStream-statement where i read the image from disk. <strong>How do i stream the data (Buffer at this stage) to the client? Can i do this differently, perhaps not using socket.io-stream?</strong> "data" is just one part of the whole image, so perhaps two or three "data"-objects need to be put together to form the complete image.

  I tried using "stream.write(data, "binary") ;" which did transfer the Buffer-objects, problem is that there is not end of stream-event and therefore i do not know when an image is complete. I tried registering to stdout.on "close", "end", "finish", nothing triggers. Am i missing something ? Am i making it overly complex ? The reasoning behind my implementation is that i need a new stream for each complete image, is that right ?

  Thanks alot !

• RTSP Client for H264 Audio/Video Stream

  9 février, par Jean-Philippe Encausse

  I'm looking for a simple way to get data of an IP Camera RTSP Stream (using H264 Audio/Video) and get on the other side

  



  

  • a frame by frame byte[]

  


  • a stream of the audio

  


  



  After many research

  



  

  • EmguCV Capture seems hanging forever (no answer from forum)

  


  • There is many (too big) RTSP Server few decode H264

  


  • There is "slow" ffmpeg wrapper

  


  • There is some managed DirectShow wrapper

  


  



  So I don't know where to go ? And how to do this ?

  



  It seems iSpyCamera is doing the job but it's a big project not a little library to query ip cameras.
