• Auto rotate overlay image on video using ffmpeg through java

  20 June 2019, by 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 February 2013, by 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?

• Java FFmpeg no output

  31 December 2018, by Games9999

  I´ve run into problem. I want to convert video using ffmpeg but it gives me no output

  public void convert(String inputFile, String outputFile, String ... optionalParams) {
  
      ProcessBuilder processBuilder = new ProcessBuilder("ffmpeg", "-i", "\"" + inputFile.trim() +"\"", "\""+ outputFile.trim() + "\"");
  
      DownloadRecord downloadRecord = table.getItems().get(0);
  
      downloadRecord.setStatus("Downloading");
  
         // Try to execute process
  
         try {
  
             // Set the working directory
  
             processBuilder.directory(new File(workingDirectory));
  
             //Start the process
  
             Process process = processBuilder.start();
  
  
  
             // Read the output from cmd
  
             BufferedReader r = new BufferedReader(new InputStreamReader(process.getInputStream()));
  
             BufferedReader ra = new BufferedReader(new InputStreamReader(process.getErrorStream()));
  
  
  
             String line;
  
             String errline;
  
             while ((line = r.readLine()) != null) {
  
                  System.out.println(line);
  
             }
  
  
  
             while ((errline = ra.readLine()) != null) {
  
                  System.out.println(errline);
  
             }
  
             process.waitFor();
  
             System.out.println("the end");
  
         } catch(IOException | InterruptedException e) {
  
             System.out.println(e.toString());
  
         }
  
  }

  I’ve been searching on stackoverflow and find some solutions, none worked. What I tried and figured out so far

  • No output or error output
  • I tried to remove backslashes from ProcessBuilder, it
    also gives me no output
  • I tried to let the program running, but it never finishes
  • I tried to use full path to the ffmpeg, no changes
  • I tried to run the video, no error
  • I am using
    Netbeans IDE so I tried clean and rebuild project, no change
  • process also never finishes

  I would like from it an output. Does someone know what I am doing wrong here ?
