• xuggler failed to write header to container

  13 juillet 2015, par user3601262

  I am trying to download video from RTSP stream to a file on my computer using the Xuggler 5.4 library.

  String outputFilename = "D:\\downloadedrtsp.avi";
  
  String inputSource = "rtsp://[ip-address]:[port]/user=[username]&[password]=password&channel=1&stream=1.sdp";
  
  
  
      try {
  
          IContainer container = IContainer.make();
  
          IMetaData im = IMetaData.make();
  
          im.setValue("max_delay", (1000000l) + "");
  
          int retval = im.setValue("rtsp_transport", "tcp");
  
  
  
          container.open(inputSource, IContainer.Type.READ, null, false, true, im, null);
  
          IMediaReader mediaReader = ToolFactory.makeReader(container);
  
  
  
          IMediaWriter mediaWriter = ToolFactory.makeWriter(outputFilename, mediaReader);
  
  
  
          mediaReader.addListener(mediaWriter);
  
  
  
          IError error;
  
          while ((error = mediaReader.readPacket()) == null) {
  
              logger.info("reading packet");
  
          }
  
      } catch (Exception e) {
  
          e.printStackTrace();
  
      }

  But the code fails with a stacktrace

• Ffmpeg hangs when -vcodec copy specified (called from Java via ProcessBuilder)

  24 juin 2015, par Inglonias

  I’m trying to use ffmpeg to export an array of bytes to a video file, but the people I work with insist that I use -vcodec copy in the arguments for it. This, however, causes the code to hang, whereas if I don’t use -vcodec copy, the code will not hang. I don’t know what the problem is, and I’ve been trying to debug this code for the past two hours.

  Here is the relevant section of code. I’ve added comments above and below the line where the code hangs. Can anybody help me ?

          // This is the tricky part. We need to build an ffmpeg process that
  
          // takes input from stdin, and then plug Java into that.
  
          ProcessBuilder ffmpegBuilder = new ProcessBuilder();
  
          String[] cmd = {"ffmpeg", "-i", "-","-vcodec", "copy", directory
  
                  + "/" + fileName};
  
          StringBuilder combinedCmd = new StringBuilder();
  
          for (String s : cmd) {
  
              combinedCmd.append(s);
  
              combinedCmd.append(" ");
  
          }
  
          mLogger.log(Level.INFO,"Final command is " + combinedCmd.toString());
  
          ffmpegBuilder.command(cmd);
  
          ffmpegBuilder.redirectErrorStream(true); // So that stdout and stderr go
  
                                                      // to the same stream.
  
          byte[] dataToWrite = new byte[data.size()];
  
          for (int i = 0; i < dataToWrite.length; i++) {
  
              dataToWrite[i] = data.get(i); // Is there really STILL no better way
  
                                              // to convert an ArrayList to an
  
                                              // array?!
  
          }
  
          try {
  
              Process ffmpeg = ffmpegBuilder.start();
  
              OutputStream stdin = ffmpeg.getOutputStream();
  
              BufferedReader stdout = new BufferedReader(new InputStreamReader(
  
                      ffmpeg.getInputStream()));
  
  //HANGS AT THIS LINE vvvvvvvvvvvvvvvv
  
              stdin.write(dataToWrite);
  
  //HANGS AT THIS LINE ^^^^^^^^^^^^^^^^
  
  
  
              String line = "I know a song that gets on everybody's nerves...";
  
              while ((line != null) && stdout.ready()) {
  
                  line = stdout.readLine();
  
                  mLogger.log(Level.INFO, line);
  
              }
  
              try {
  
                  ffmpeg.waitFor(2, TimeUnit.SECONDS);
  
                  ffmpeg.destroyForcibly();
  
              } catch (InterruptedException e) {
  
                  // TODO Auto-generated catch block
  
                  e.printStackTrace();
  
              }
  
          } catch (IOException e) {
  
              // TODO Auto-generated catch block
  
              e.printStackTrace();
  
          }

  I just need to enable gd support for ffmpeg. I’ve tried using ./configure --enable-skip-gd-check and nothing has worked. I’ve scoured google for the last 12 hours and tried every "solution" so any advice is appreciated. Thanks.

  Terminal output after ./configure --enable-skip-gd-check :
