• How can I read a live webstream in java using xuggle ? (I can do it in ffmpeg, just not xuggle)

  25 février 2013, par Grammin

  So if I run :

  ffmpeg -t 10 -re -i "rtmp://170.93.143.150/rtplive/ app=rtplive/ playpath=e000990f025f0075004d823633235daa swfUrl=http://www.chart.state.md.us/video/mediaplayer/player.swf pageUrl=http://www.chart.state.md.us/video/video.asp?feed=e000990f025f0075004d823633235daa stop=5000 flashver=`LNX 11,2,202,262` live=true" test.flv -report

  It gives me a 5 second snapsnot of video from that webstream that gets put into test.flv.
  Now I would like to do the same thing in java using xuggle except everytime I try and open the container it errors out on me and sets x to -1 :

   public IMediaReader grabStream(IMediaReader reader) throws IOException
  
    {
  
      String rtmp = "rtmp://170.93.143.150/rtplive/";
  
      rtmp = rtmp + " app=rtplive/";
  
      rtmp = rtmp + " playpath=e000990f025f0075004d823633235daa";
  
      rtmp = rtmp + " swfUrl=http://www.chart.state.md.us/video/mediaplayer/player.swf";
  
      rtmp = rtmp + " pageUrl=http://www.chart.state.md.us/video/video.asp?feed=e000990f025f0075004d823633235daa";
  
      rtmp = rtmp + " flashver=`LNX 11,2,202,262`";
  
      rtmp = rtmp + " live=true";
  
  
  
      IContainer container = IContainer.make();
  
      IMediaReader newReader = ToolFactory.makeReader(container);
  
  
  
      int x = container.open(rtmp, IContainer.Type.READ, null, true, false);
  
  
  
      if (x < 0)
  
      {
  
        IError ie = IError.make(x);
  
        System.out.println("Open error: " + ie.getType().toString());
  
        throw new RuntimeException("failed to open with error" + x);
  
      }
  
  
  
      return newReader;
  
    }

  Maybe the best way to do it is to stream in ffmpeg to a xuggle container using inputstream somehow ? Or maybe there is another way to stream in a webstream to java ?

• What kind of stream GStreamer produce ?

  16 novembre 2014, par Max

  I use following 2 commands to stream video from Raspberry Pi

  RaPi

  raspivid -t 999999 -h 720 -w 1080 -fps 25 -hf -b 2000000 -o - | gst-launch-1.0 -v fdsrc ! h264parse !  rtph264pay config-interval=1 pt=96 ! gdppay ! tcpserversink host=$RA-IP-ADDR port=5000 

  Linux Box

  gst-launch-1.0 -v tcpclientsrc host=$RA-IP-ADDR port=5000  ! gdpdepay !  rtph264depay ! avdec_h264 ! videoconvert ! autovideosink sync=false 

  But what kind of stream is it ? Can I read it with OpenCV ? or convert with avconv|ffmpeg nc $RA-IP-ADDR 5000 | avconv ? or watch with VLC ?

• Save Gstreamer stream at Windows side [closed]

  18 février 2013, par user1336117

  I am streaming video from webcam from linux via gstreamer as below :

  gst-launch -v v4l2src device=/dev/video0 ! videorate  ! video/x-raw-yuv, width=320, height=240, framerate=5/1  ! videobalance saturation=0.0 ! jpegenc ! multipartmux ! tcpserversink host=192.168.10.24 port=5000

  I can see the stream via VLC

  tcp://192.168.10.67:5000

  As the next step I want to save it as a video file but I could not succeeded.
  I tried to setup gstreamer to windows but it did not worked.
  I tried to save the stream by using ffmpeg on windows side but it did not worked.

  ffmpeg -i tcp://192.168.10.67:5000 -map 0 deneme.flv

  What should I do to be able to save the stream on windows side ?
