• Java Android Library relocates/realignes all centered texts

  9 août 2019, par Manuel Maurer

  Recently I noticed a very weird situation : Whenever I try to run a FFMpeg-Command with either https://github.com/tanersener/mobile-ffmpeg or https://github.com/bravobit/FFmpeg-Android, it changes the texts on all my other activities.

  I’m starting a thread, which saves an overlay to a video. Yes, I need to use FFMPEG, because I need it in some other places too. The strange thing is, that whenever I start the FFMPEG-Command, all the Texts in my app, that were centered before (textAlign->Center) are now aligned left.

  How can that even happen ?

• Auto rotate overlay image on video using ffmpeg through java

  20 juin 2019, par Ramavath Nirmala

  I need to auto rotate overlay image on video using ffmpeg commands ?

  I have tried with specifying angle but my goal is to auto rotate image on video.

  ffmpeg -i mersyvideo.mp4 -i avatar.jpg -filter_complex "[1:v] rotate=-    30*PI/180:c=none:ow=rotw(iw):oh=roth(ih) [rotate];[0:v][rotate] overlay=40:10" -codec:a copy output/overlayavatar.mp4

  I am specifying angle in command.so its giving output with specified angle. I need to rotate image on video

• 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 ?
