• Xuggler Error : Could Not Open

  22 septembre 2012, par MalTec

  I am using xuggler API to transcode Video from one format to another.

  Following the example, provided by

  http://wiki.xuggle.com/MediaTool_Introduction & http://www.javacodegeeks.com/2011/02/xuggler-tutorial-transcoding-media.html

  public void convertVideo(){
  
  
  
       String sourceUrl=getResourceDirectory()+"/in/AV36_1.AVI";
  
       String destUrl=getResourceDirectory()+"/out/output.mp4";
  
  
  
       IMediaReader reader = ToolFactory.makeReader(sourceUrl);
  
  
  
          // add a viewer to the reader, to see progress as the media is
  
          // transcoded
  
          reader.addListener(ToolFactory.makeViewer(true));
  
  
  
       // create a writer which receives the decoded media from
  
       // reader, encodes it and writes it out to the specified file
  
       IMediaWriter writer = ToolFactory.makeWriter(destUrl, reader);
  
  
  
       // add a debug listener to the writer to see media writer events
  
       writer.addListener(ToolFactory.makeDebugListener());
  
  
  
  
  
  ////
  
  ////        // create the media writer
  
          reader.addListener(ToolFactory.makeWriter(destUrl, reader));
  
  
  
          // read packets from the source file, which dispatch events to the
  
          // writer, this will continue until 
  
  
  
  
  
          while (reader.readPacket() == null)
  
            do {} while(false);
  
      }

  Provides Could Not Open Exception :

    Exception in thread "main" java.lang.RuntimeException: could not open: D:\Malhar\project_works\VideoConvertter/resources/in/AV36_1.AVI

  Have tried with different file to.. But, the result is same.

• Error in installing Open-CV with ffmpeg

  24 décembre 2013, par Matteo

  I am trying to install the library Open-CV working on on Ubuntu 11.04.

  I followed all instructions found in the InstallationGuide.

  However after installing with success I realized that I hadn't FFMPEG support because in my configuration file FFMPEG was disabled :

  Video I/O: 
  
  --     DC1394 1.x:                 NO 
  
  --     DC1394 2.x:                 YES 
  
  --     FFMPEG:                     NO 
  
  --       codec:                    YES 
  
  --       format:                   YES 
  
  --       util:                     YES 
  
  --       swscale:                  NO 
  
  --       gentoo-style:             YES 
  
  --     GStreamer:                  YES 
  
  --     UniCap:                     NO 
  
  --     PvAPI:                      NO 
  
  --     V4L/V4L2:                   Using libv4l 
  
  --     Xine:                       NO

  So I tried to rebuild everything after installing FFMEPG as decribed here.

  After configuring installation with the instruction

  cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON ../OpenCV-2.3.1

  I ran the make command getting this error :

  make[2]: *** [bin/opencv_test_calib3d] Error 1
  
  make[1]: *** [modules/calib3d/CMakeFiles/opencv_test_calib3d.dir/all] Error 2
  
  make: *** [all] Error 2

  This is the point of compilation where the error is coming out :

  can anybody please tell me what's the problem with installation process I'm following ?

  Why is there this library referentiation error ?
